Jaipho Dynamic iPhone Gallery with ASP.Net c#

2011-10-23T12:52:00.003+05:30

few days back i gone through a html/javascript iphone optimized photo gallery at http://www.jaipho.com/
Really cool way to create a gallery that looks awesome on smart phone.
What if you can create this gallery in dynamic way...!!
Here i made a solution that parses xml from a flikr rss feed and shows this on your browser directly. Here is the xml structure of flikr looks like-

You have to parse media:content and media:thumbnail through your server side code and after this you have to send them to client side of the page.
currently if you open index.html file on a editor then you will see the page contain detail of 2 image path and its detail at very end of the page.

so what you have to do, you have to fill dao.ReadImage( 0,'','','',''); method dynamically through server side code. For this you have to create a ASP.Net atmosphere for your project. So create a new asp.net c# project and at you root directory place all files and directories of JAIPHO that contain all files in same structure.
Now your default.aspx file and index.html file should contain in the same base directory.
The next thing you have to copy and paste all code between and tag from index.html to Default.aspx. Now if you will run your Default.aspx file, it should run normally as your index.html file runs. Add 2 text boxes to the default.aspx page with id TextBox1 and TextBox2.
Next step is to start making code for the parsing of the flikr rss. Here is the way i made-

the code above grabs thumb and image urls from the rss feed and appends them with a comma (,). After committing the whole for loop, both of your textboxes has comma separated urls of image and thumb image.
Now come to your .aspx file. Comment all lines than contains sets of image path and titles i.e. dao.ReadImage( 0,'','','','');
What you have to do, you have to fill this dao.ReadImage( 0,'','','',''); method dynamically with the comma separated urls from your text boxes. For this you have to fill javascript array will urls at every indexes. So First take the full text of the Textbox into a var type like this. Do this just above the declaration of var dao = new Jph_Dao();
do like this-
now fill array with comma saperated urls-

doing this, myArr and myArr2 contains urls at all of its indexes.
Now here is the final step. You have to fill dao.ReadImage( 0,'','','',''); with the help of a for loop-

Now when you run the Default.aspx, this will take images from flikr rss and will execute gratefully.

iPhone Application Ad Hoc Distribution Step 1

2011-02-17T18:44:00.004+05:30

NOTE- this tutorial is based on iphone dev SDK 4.2

Ad Hoc Distribution allows you to try an application before it’s available in the iTunes App Store.

This is how we distribute iPhone applications to selected peoples as a beta release

The Apple method requires pre-registration of beta testers. In order to register them you need to know their devices unique device identifier (UDID) and then create a mobile provisioning file - a security certificate that authorizes that unique device to run the App being tested.
You are limited to 100 devices per App using this method meaning you can only have 100 beta testers.
Here are the steps to follow-
Step 1: Open up your ad hoc provisioning profile in Text Edit and verify that it contains a “<key>get-task-allow</key>”. If it does not, generate a new provisioning profile using the Program Portal.

Step 2

UITextView with HTML

2010-09-14T14:26:00.001+05:30

You must bother sometimes when you need to display a multi color text in your application! You must be using many uilabels with fissrent color. But you need not do this all. Here is a simple way to show your HTML file directly into UITextView.

What you need is to save all text into a html file and call that file in your UITextView with the help of this code bellow-


 // Load the HTML source

 self.sourceText = [NSString stringWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"htmlfile" ofType:@"html"]];

 [myTextView setContentToHTMLString:self.sourceText];

UITableView with Textfield Controls auto Moved Up on select

2010-09-14T11:48:00.004+05:30

This example shows a signup page with UITextFields and UILabels. When a field is selected by a user then it doesn't get overlapped by the keypad, textfields automatically moves up on select and auto moves down on 'done' button click.

Remember, you can easily implement same concept using UITableViewController, but in that case there will not be more customization options like, static background image etc. So this example is based on UIViewController with UITableViewDelegate.

The method bellow works for moving up and down of whole TableView


- (void) moveToUpDownAnimation:(NSInteger) upOrDown:(NSInteger) yAxis {

 

 [UIView beginAnimations:nil context:NULL];

 [UIView setAnimationDelegate:self];

 [UIView setAnimationDuration:0.5];

 [UIView setAnimationBeginsFromCurrentState:YES];

 itemTableView.frame = CGRectMake(itemTableView.frame.origin.x, (itemTableView.frame.origin.y + yAxis), itemTableView.frame.size.width, 368);

 heading.frame = CGRectMake(heading.frame.origin.x, (heading.frame.origin.y + yAxis), heading.frame.size.width, heading.frame.size.height);

 [UIView commitAnimations];

}
