iPhone - How to download big amount of files

noemail@noemail.org (Oleg) — Wed, 16 May 2012 09:09:05 GMT

I need to download a number of files from the server. What is the best way to do it? All documents are stored in NSMutableArray and for each documents there are two files - the document itself and its change log. So what I do is:

- (void)downloadDocuments:(int)docNumber
{
    NSString *urlString;
    NSURL *url;   
    for (int i=0; i<[items count]; i++) {
        [progressBar setProgress:((float)i/[items count]) animated:YES];
        urlString = [[items objectAtIndex:i] docUrl];
        url = [[NSURL alloc] initWithString:[urlString stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]];
        [self downloadSingleDocument:url];
        urlString = [[items objectAtIndex:i] changeLogUrl];
        url = [[NSURL alloc] initWithString:[urlString stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]];
        [self downloadSingleDocument:url];
    }
    urlString = nil;
    url = nil;
    [self dismissModalViewControllerAnimated:YES];
}

- (void)downloadSingleDocument:(NSURL *)url
{
    NSMutableURLRequest *req = [NSMutableURLRequest requestWithURL:url];
    [req addValue:@"Basic XXXXXXX=" forHTTPHeaderField:@"Authorization"];
    downloadConnection = [[NSURLConnection alloc] initWithRequest:req delegate:self startImmediately:YES];
}

- (void)connection:(NSURLConnection *)conn didReceiveResponse:(NSURLResponse *)response
{
    if (conn == downloadConnection) {
        NSString *filename = [[conn.originalRequest.URL absoluteString] lastPathComponent];
        filename = [filename stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

        filePath = [[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:filename];
        [[NSFileManager defaultManager] createFileAtPath:filePath contents:nil attributes:nil];

        file = [[NSFileHandle fileHandleForUpdatingAtPath:filePath] retain];
        if (file)
        {
            [file seekToEndOfFile];
        }
    }

}


- (void)connection:(NSURLConnection *)conn didReceiveData:(NSData *)data
{
    if (conn == downloadConnection) {
        if (file) { 
            [file seekToEndOfFile];
        }
        [file writeData:data];
    }

}


- (void)connectionDidFinishLoading:(NSURLConnection *)conn
{

    if (conn==downloadConnection) {
        [file closeFile];
    }
}

And my problem is that only the last file is downloaded. Any suggestions on what I am doing wrong? Thanks in advance for help!

I want to download a large video file to Iphone in my app. I used NSURLConnection and saving the file to disk once it completly downloads the video.

As my video is large, it is crashing in middle.

Is there anyway like directly saving the file to disk without keeping it in memory.

How to download large files in iOS?

noemail@noemail.org (Strong Like Bull) — Sun, 12 Jun 2011 14:56:08 GMT

I'm trying to download files [> 40MB] from web server over HTTP request. To do that I've used the SimpleURLConnection sample provided by the apple. In that sample they only download the image files, so I modified the code to download pdf files and stored it in application's document directory. This is working fine to download small files, but it only download 6.4MB of data if I trying to download large files [>40Mb]. please help me to fix this,

Thank you,

FYI:

code to write file with downloaded data

  - (void)connection:(NSURLConnection *)theConnection didReceiveData:(NSData *)data
    // A delegate method called by the NSURLConnection as data arrives.  We just 
    // write the data to the file.
{
    #pragma unused(theConnection)
    NSInteger       dataLength;
    const uint8_t * dataBytes;
    NSInteger       bytesWritten;
    NSInteger       bytesWrittenSoFar;

    assert(theConnection == self.connection);

    dataLength = [data length];
    dataBytes  = [data bytes];

    bytesWrittenSoFar = 0;
    do {
        bytesWritten = [self.fileStream write:&dataBytes[bytesWrittenSoFar] maxLength:dataLength - bytesWrittenSoFar];
        assert(bytesWritten != 0);
        if (bytesWritten == -1) {
            [self _stopReceiveWithStatus:@"File write error"];
            break;
        } else {
            bytesWrittenSoFar += bytesWritten;
        }
    } while (bytesWrittenSoFar != dataLength);
}

iOS browsers double-back (skip page) when returning from external URL redirect in Next.js Pages Router [closed]

noemail@noemail.org (pavan lucky) — Mon, 21 Sep 2026 16:13:16 GMT

I am experiencing a severe history stack issue in a Next.js (Pages Router) application. The bug specifically happens on iOS 27 and above across all WebKit browsers (Safari, Chrome, Opera). Devices running older iOS versions (iOS 26 and below), Android devices, and desktop browsers (macOS/Windows) work perfectly.

The ScenarioA user is on Page Pre-A.The user navigates natively to Page A (my Next.js page). On Page A, the user clicks an external link (e.g., a Single Sign-On (SSO) login via a GET request, a banner advertisement, or a basic anchor tag hyperlink). The browser successfully leaves the app and loads https://external-site.com. On the external website, the user clicks the browser's native Back button. Expected Behavior is - The user should return cleanly to Page A.Actual Behavior (iOS 27+ Only) The browser completely skips Page A and lands all the way back on Page Pre-A (an unintended double-back navigation).

What I have tried :: I have tested multiple ways to trigger the external redirect from Page A, but iOS 27+ consistently drops Page A from the history stack context upon returning:

Standard Anchor Tag:jsx<a href="https://external-sso.com" rel="noopener noreferrer">Login Link</a>

Window Location Assignment:javascriptwindow.location.href = "https://external-site.com";

"Load More" in UITableView

noemail@noemail.org (Allen) — Fri, 10 Dec 2010 15:17:02 GMT

I'm loading an RSS feed into a table view. I'm going to load 10 entries and then would like it say "Load More" in the last cell or somewhere below the last cell, so when the user clicks on Load More, the rest of the RSS feed gets loaded. Since the RSS comes off of my web site, I can program it to get the 10 or all entries on the server side (using a query string or something).

The question is how to render a table such that the last cell has a Load More link that the can clicked to call a method to load the rest of the feed (and then when the entire feed is loaded there is no more "Load More" link).

Fill a plist with quotes

noemail@noemail.org (user717452) — Thu, 2 Aug 2012 15:34:09 GMT

I have been doing some work for a while on an iPhone daily quote app, and the bulk of comments I received are to use a plist to store the quotes, and then setup the code to randomly access a quote each day. I have never really worked with a plist though, and am unsure as to the best way to build a new one filled with quotes. Could I get some guidance on this?

What WordPress Forms/Quiz plugin is good for Desktop and Mobile?

noemail@noemail.org (Janina Elijoki) — Fri, 8 May 2026 08:29:22 GMT

I'm creating a website in WordPress that will include multiple (5-10) quizzes and I need it to work well on desktop and mobile.

The quizzes are composed of around 20-40 questions, which the user will answer on a scale of strongly disagree to strongly agree. I'm intending to use radio buttons for this.

The quizzes have also been split to 5-10 sections and each section will be scored separately and results will be given per section.
After completing the quiz and getting their results the user should also have the option to upload a pdf or send a pdf to their email of their results.
The results should contain a summary of the users answer as well as the actual results based on the scoring of the sections.

Previously I used the Forminator plugin for this and it had all the necessary features required, but I ran into an issue attempting to use the website and fill the form/quiz on iOS devices. The form/quiz was very slow to load and to respond to inputs and as the quiz went on it became impossible to use due to the long load and response times. On desktop and on Android devices the quiz worked fine.

Has anyone encountered the same problems?

What other form/quiz plugin would you recommend for me that would also work on iPhone without the performance issues?

How to determine the current iPhone/device model?

noemail@noemail.org (The Mach System) — Thu, 25 Sep 2014 01:08:01 GMT

Is there a way to get the device model name (iPhone 4S, iPhone 5, iPhone 5S, etc) in Swift?

I know there is a property named UIDevice.currentDevice().model but it only returns device type (iPod touch, iPhone, iPad, iPhone Simulator, etc).

I also know it can be done easily in Objective-C with this method:

#import <sys/utsname.h>

struct utsname systemInfo;
uname(&systemInfo);

NSString* deviceModel = [NSString stringWithCString:systemInfo.machine
                          encoding:NSUTF8StringEncoding];

But I'm developing my iPhone app in Swift. What is the equivalent way to solve this in Swift?

"Safari cannot open the page because the address is invalid" for Google Maps link

noemail@noemail.org (Adam Hollock) — Thu, 20 Nov 2014 20:46:14 GMT

I have an iPhone 4s with iOS7 that doesn't have the Google Maps app installed on it. Whenever I try to navigate to a location link on it, it flashes an error at me that says:

Cannot Open Page
Safari cannot open the page because the address is invalid

But then the error goes away (without having to hit OK) and the map shows up, and all subsequent Google Maps links load without this error. When I clear my cache, the error shows up again, but only for the first time, and again disappears on its own.

This is the link in question that I am using, but I have tested it with multiple links and the problem seems to be persistent:

https://www.google.com/maps/place/Kraftwork/@39.971494,-75.127336,17z/data=!3m1!4b1!4m2!3m1!1s0x0:0x6db3f86eca2f8b45?hl=en

Any idea what's causing this problem?

To be specific, this problem exists as a result of straight html and just attempting to click a maps link.

How can i display animated svg file in iOS without using UIWebView

noemail@noemail.org (Mihir Mehta) — Tue, 4 Jul 2017 12:49:24 GMT

Currently i am using UIWebView to display animated svg file in my native iOS application.

This works fine except the CPU usage is constantly being on higher side as long as app is in foreground.

Is there any better way to display svg file without using UIwebView

I have already tried many third party libraries but all works only with static svg file not animated svgs

I have tried following

https://github.com/mchoe/SwiftSVG

https://github.com/exyte/Macaw

https://github.com/onmyway133/Snowflake

https://github.com/SVGKit/SVGKit

My app supports iOS 9 and above , My code is in Swift3

Here is the link of on of the svg file that i am trying to display

UIManagedDocument example / tutorial

noemail@noemail.org (adamteale) — Mon, 2 Jan 2012 22:26:45 GMT

I have been trying very unsuccessfully to create a simple UIManagedDocument library style application (separate documents saved to iCloud).

I am confused with the following:

Do I subclass UIManagedDocument and set up the persistentStoreCoordinator, ManagedObjectModel & ManagedObjectContext within this subclass, or are these supposed to be configured within the AppDelegate (and if so, how do I go about refreshing the persistentStoreCoordinator to look at the new file - it seems that once that has read a persistentStore that I can't get it to read a new persistent store)?

FBPermissionDialog bug, showing "Welcome to Facebook" page

noemail@noemail.org (Oliver) — Sun, 16 May 2010 22:17:19 GMT

I'm experiencing a weird bug that I can replicate pretty consistently with the FBConnect iPhone SDK, more specifically with the class FBPermissionDialog. The result is that instead of seeing the standard extended permissions dialog, the user is shown this:

The only way around it is for the user to delete the app and reinstall.

This is how I have replicated it:

On first login, the user is asked for extended permissions on something (the dialog displays correctly). The user declines the permission. User quits the app.
The user relaunches the app and since we still need the permission, we ask again.
Instead of the permission dialog, the user is shown the "Welcome to Facebook" page.

The only way for the user to get asked again is to delete the app and reinstall. Has anyone else experienced this? Is there a workaround? Here is the code I use to ask for permission, I believe it's pretty standard.

// Create a permission dialog
FBPermissionDialog *dialog = [[[FBPermissionDialog alloc] init] autorelease];
dialog.delegate = self;
dialog.permission = @"read_stream";
[dialog show];

NSArchiver vs NSKeyedArchiver performance

noemail@noemail.org (Ben Quan) — Tue, 10 Jan 2012 16:06:12 GMT

Why is NSKeyedArchiver performance so poor? The size doubles vs using NSArchiver.

I am encoding an NSMutableArray of objects with the following line

BOOL result = [NSArchiver archiveRootObject:self.appDataObject.materias toFile:archivePath];

the NSMutableArray contain custom objects that have their corresponding encodeWithCoder and initWithCoder

-(void)encodeWithCoder:(NSCoder *)aCoder
{

    [aCoder encodeObject: _fileName];
    [aCoder encodeObject: _categoria];
    [aCoder encodeObject: _materia];
    [aCoder encodeObject: _nombre];

    [aCoder encodeObject: _position];
    [aCoder encodeValueOfObjCType:@encode(BOOL) at:&_favorite];

}

-(id)initWithCoder:(NSCoder *)aDecoder
{
    if (self=[super init]) {
        [self setFileName:[aDecoder decodeObject]];
        [self setCategoria:[aDecoder decodeObject]];
        [self setMateria:[aDecoder decodeObject]];
        [self setNombre:[aDecoder decodeObject]];

        [self setPosition:[aDecoder decodeObject]];
        [aDecoder decodeValueOfObjCType:@encode(BOOL) at:&_favorite];
    }

    return self;
}

it works fine as it saves the file properly and then I am able to unarchive it. They are around 3000 objects and the output file is about 900kB

The problem occurs when I change my archiving line to:

BOOL result = [NSKeyedArchiver archiveRootObject:self.appDataObject.materias toFile:archivePath];

Everything magically works BUT the file size more than doubles to 2MB!

Why am I asking this? because I am developing a iOS application and therefore lose support of NSArchiver.

Perspective correction of UIImage from Points [closed]

noemail@noemail.org (Jakob Halskov) — Tue, 22 Nov 2011 23:16:50 GMT

I'm working on an app where I'll let the user take a picture of a business card or photograph.

The user will then mark the four corners of the object (which they took a picture of) like it is seen in a many document/image/business card scanning apps:

How do I crop and fix the perspective according to these four points? I've been searching for days and looked at several image proccessing libraries without any luck.

Any one who can point me in the right direction?

NSURLConnection/CFURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9813)

noemail@noemail.org (Ruchir Shah) — Sun, 24 May 2015 05:23:49 GMT

I am trying for an HTTP call on https. Here is my code snippet.

NSMutableURLRequest *request = [[NSMutableURLRequest alloc]
                                initWithURL:[NSURL
                                             URLWithString:@"https://testservice.fiamm.com/token"]];

[request setHTTPMethod:@"POST"];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-type"];

NSString *postString = @"username=TestIphone&Password=T3st1ph$n&Grant_type=password";

[request setValue:[NSString stringWithFormat:@"%d", [postString length]] forHTTPHeaderField:@"Content-length"];

[request setHTTPBody:[postString
                      dataUsingEncoding:NSUTF8StringEncoding]];

// Fetch the JSON response
NSData *urlData;
NSURLResponse *response;
NSError *error;

// Make synchronous request
urlData = [NSURLConnection sendSynchronousRequest:request
                                returningResponse:&response
                                            error:&error];

// Construct a String around the Data from the response
NSString *strFiamm = [[NSString alloc] initWithData:urlData encoding:NSUTF8StringEncoding];

When I try in hurl or postman I get response proper but when I try in my code I get this error.

NSURLConnection/CFURLConnection HTTP load failed (kCFStreamErrorDomainSSL, -9813)

Any help or suggestions appreciated.!

How to get CSRF token in iOS?

noemail@noemail.org (Joey Franklin) — Sat, 12 Jan 2013 21:19:43 GMT

So I'm trying to POST form data to my colleague's site in order login (simple username and password) from my iPhone app. However, it appears that I need a CSRF Token in order to post. I've done a lot of research on this and from what I can obtain this token from the csrftoken cookie ( I read that here: https://docs.djangoproject.com/en/dev/ref/contrib/csrf/) using a GET request. The problem is, I don't know what exactly to do with this GET request? Where do I get from?

Here is the code so far for my post request:

NSURL *url = [NSURL URLWithString:SERVER_ADDRESS];
NSData* postData= //Some form data
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url];
[request setHTTPMethod:@"POST"];
[request setValue:[NSString stringWithFormat:@"%d", postData.length] forHTTPHeaderField:@"Content-Length"];
[request setValue:@"application/x-www-form-urlencoded charset=utf-8" forHTTPHeaderField:@"Content-Type"];
[request setHTTPBody:postData];

[request addValue:token forHTTPHeaderField:@"X-CSRFToken"];  //Where do I get this token from

NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request
                                                              delegate:self];
[connection start];

I know there are a lot of similar posts to this on StackOverflow, but I haven't found any with an answer that seems complete. Usually it just directs me to the link above which is only filled with AJAX related info. Help would be much appreciated!

How to change iPhone deployment target

noemail@noemail.org (delmin) — Thu, 2 Apr 2020 09:44:42 GMT

I have updated flutter today also with Xcode and I'm getting an error when trying to run my app on IOS

warning: The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 7.0, but the range of supported deployment target versions is 8.0 to 13.4.99. (in target 'gRPC-C++-gRPCCertificates-Cpp' from project 'Pods')

...

When I go to a runner from Xcode I can only change it to min version 8

Azure Point to Site VPN connection from IOS / IPad / IPhone [closed]

noemail@noemail.org (Murray Foxcroft) — Thu, 23 Nov 2017 12:25:52 GMT

Is it possible to connect from an IOS device to an Azure Point to Site VPN? (Yes, I know it is unsupported). However, I have seen it suggested that SSTP could be used, but cant find a concrete example.

Can anyone shed some light on if this is actually possible - or suggest alternatives?

While I am entering text in one field, it is diplaying the same text in some other textfield too

noemail@noemail.org (iosDev) — Fri, 18 May 2012 10:17:24 GMT

When I am entering text in textfield 1, that text is also displayed in textfield 9.

Here is some code what I did to create textfield in tableview cell.

I added textfield in tableview cell, like below in the cellforRowatintexpath method.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    static NSString *CellIdentifier = @"myCell";
    //UILabel* nameLabel = nil;
    cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if(cell == nil)
    {
        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
        cell.selectionStyle = UITableViewCellSelectionStyleNone;
    }
    else
    {
        UILabel *titleLbl = (UILabel *)[cell viewWithTag:1];
        [titleLbl removeFromSuperview];
    }
    nameLabel = [[UILabel alloc] initWithFrame:CGRectMake(7.0, 10.0, 160.0, 44.0)];
    nameLabel.text = [labels objectAtIndex:indexPath.row];
    nameLabel.font = [UIFont boldSystemFontOfSize:12];
    nameLabel.lineBreakMode = UILineBreakModeWordWrap;
    nameLabel.tag = 1;
    nameLabel.numberOfLines = 0;
    [nameLabel sizeToFit];
    CGSize expectedlabelsize = [nameLabel.text sizeWithFont:nameLabel.font constrainedToSize:nameLabel.frame.size lineBreakMode:UILineBreakModeWordWrap];
    CGRect newFrame = nameLabel.frame;
    newFrame.size.height = expectedlabelsize.height;
    [cell.contentView addSubview: nameLabel];
    [nameLabel release];


    // Adding textfield to tableview cell.
    tv = [[UITextField alloc] initWithFrame:CGRectMake(nameLabel.frame.origin.x + nameLabel.frame.size.width + 2, 10.0, cell.contentView.bounds.size.width, 30)];
    tv.tag = indexPath.row + 2;
    //tv.text = [labels objectAtIndex:indexPath.row];
    tv.font = [UIFont boldSystemFontOfSize:12];


    // This method will take text from textfield of tableview cell using their individual tag
    [tv addTarget:self action:@selector(getTextFieldValue:) forControlEvents:UIControlEventEditingDidEnd];

    [cell.contentView addSubview:tv];

    [tv setDelegate:self];

    [tv release];

    return cell;
}

And here is the getTextFieldValue method:

- (void) getTextFieldValue:(UITextField *)textField {

    if (textField.tag == 2) {

        //NSString *value1 = [NSString stringWithFormat:@"%@", textField.text];
        //NSLog(@"value1 is %@", value1);.

        NSLog(@"2--->%@", textField.text);
    }else if(textField.tag == 3) {
        NSLog(@"3--->%@", textField.text);
    }else if(textField.tag == 4) {
        NSLog(@"4--->%@", textField.text);
        }
    else if(textField.tag == 5) {
        NSLog(@"5--->%@", textField.text);
    }
    else if(textField.tag == 6) {
        NSLog(@"6--->%@", textField.text);
    }
    else if(textField.tag == 7) {
        NSLog(@"7--->%@", textField.text);
    }
    else if(textField.tag == 8) {
        NSLog(@"8--->%@", textField.text);
    }
    else if(textField.tag == 9) {
        NSLog(@"9--->%@", textField.text);
    }
    else if(textField.tag == 10) {
        NSLog(@"10--->%@", textField.text);

verification failed as the authority is invalid

noemail@noemail.org (user3009033) — Tue, 19 Nov 2013 13:54:58 GMT

I'm trying to resign an ipa which is already signed with the developer certificate. Now I'm resigning with the enterprise distribution certificate. I've got proper provisioning profile, ios_distribution certificate to sign the app. I'm following this answer Re-sign IPA (iPhone) for the resigning steps. With this I'm successfully able to resign the ipa but when I try to install this via itools, I'm getting this error: verification failed as the authority is invalid.

Another thing is I'm resigning with the enterprise distribution certificate but still when i try to install the resigned ipa directly (keeping resigned ipa on dropbox) getting this error "safari can't download this file" which I believe should come when the app is not signed with the enterprise distribution certificate and someone try to download that file directly on iphone (not via appstore or itunes).This certificate says I can distribute this app outside the appstore, so I'm confused what I'm really missing.

Iphone Ipad QA testing process [closed]

noemail@noemail.org (yeahdixon) — Fri, 10 Sep 2010 19:49:22 GMT

I'm curious about how people test their apps In general.

I recently uploaded an app and wanted to reach as many iOS' as possible so i targeted it to 3.0. I did test on iphone 3, iphone 4 and 3GS but found out that there was an obscure sizing of a button image on a specific ios version.

In general how do you guys test for different versions? Do people actually keep 3, 3gs and 4. Then on each, do people test on the various versions of ios within each of the phones. Yuck, anything to make this easier?

For the simulator, each xcode download contains only latest os and hardware to target. It would be nice if it could keep older os versions on the simulator to test with, is this possible?

Avoiding atan2 in calculating angles - atan2 precision

noemail@noemail.org (wczekalski) — Sat, 7 Jan 2012 12:08:53 GMT

we, developers very often need to calculate angle to perform rotation. Usually we can use atan2() function but sometimes we need more precision. What do you do then?

I know that theoretically atan2 is precise but in my system (iOS) it's inaccurate about 0.05 radians so it's big difference. That's not just my problem. I've seen similar opinions.

noemail@noemail.org (Alexander) — Mon, 10 Dec 2012 11:54:25 GMT

I found two ways how i can easier develop web app for iPhone.

http://moduscreate.com/enable-remote-web-inspector-in-ios-6/

http://webdesign.tutsplus.com/tutorials/workflow-tutorials/quick-tip-using-web-inspector-to-debug-mobile-safari/

But I can't do it on Windows, because for windows is only Safari 5. Have you any ideas how I can solve this problem?

Bootstrap modal not working on iPhone

noemail@noemail.org (Jota) — Wed, 21 Mar 2018 14:55:35 GMT

This is the modal:

<div class="modal fade" id="modalInsertAgression" tabindex="-1" role="dialog" aria-labelledby="modalInsertAgression" aria-hidden="true">
<div class="modal-dialog" role="document">
    <div class="card">

        <form id="formInsertarAgresion" action="{% url 'insertarAgresion' %}" role="form">{% csrf_token %}
            <div class="card-header card-header-icon" data-background-color="rose">
                <i class="material-icons">place</i>
            </div>

            <div class="card-content">
                <h4 class="card-title">Test</h4>
                <p class="text-center" id="msgModalInsertAgression"></p>
                <br>

                <div class="input-group">
                    <span class="input-group-addon"><i class="material-icons">date_range</i></span>
                    <div class="form-group">{{ agresionForm.fecha }}</div>
                </div>
            </div>

            <div class="card-footer pull-right">
                <button id="btnInsertModalInsertAgression" type="submit" class="btn btn-fill btn-rose">Insertar</button>
                <button id="btnCloseModalInsertAgression" type="button" class="btn btn-default btn-fill" data-dismiss="modal">Cancelar</button>
            </div>
        </form>

    </div>
</div>

I open it with:

$("#modalInsertAgression").show();

It does not work on iPhone, when the modal appears the background keeps black and it lost the focus, you can not click in the modal or the buttons.

Edit: The modal only works with $("#modalInsertAgression").modal({backdrop: false}); but I do not want to lose the black background...

Can you do a Ping or traceroute command on iPhone? [closed]

noemail@noemail.org (mootymoots) — Fri, 9 Jul 2010 11:12:12 GMT

Odd question, I know I can do this in OS X Objective C, but can you run a ping against an IP or URL on the iPhone? Is the framework there to support it? Same with doing a traceroute.

Xcode/Simulator: How to run older iOS version?

noemail@noemail.org (Shai UI) — Tue, 23 Nov 2010 23:16:44 GMT

I'm thinking of upgrading to iOS SDK 4.2. But what I'm wondering is if I'll still be able to run the simulator as iOS 3.2. This is because I'm creating iAds for iPad but I still want to check if my program will run with iOS 3.2.

Note: I have seen a similar post to this in the past, but they weren't really helpful in giving the exact steps in how this could be done.
