Send Email with Attachment in iphone

1) In Xcode 4 goto the build phases tab for your target. Make sure you see MessageUI.framework. If it's not there click + to add a new framework.

2)In your interface file

#import <MessageUI/MFMailComposeViewController.h>

@interface YourViewController : UIViewController <MFMailComposeViewControllerDelegate>

3)Add this Method

-(void)displayComposerSheet
{
    MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
    picker.mailComposeDelegate = self;
    [picker setSubject:@"Check My Image!"];

    // Set up recipients
    // NSArray *toRecipients = [NSArray arrayWithObject:@"first@example.com"];
    // NSArray *ccRecipients = [NSArray arrayWithObjects:@"second@example.com", @"third@example.com", nil];
    // NSArray *bccRecipients = [NSArray arrayWithObject:@"fourth@example.com"];

    // [picker setToRecipients:toRecipients];
    // [picker setCcRecipients:ccRecipients];
    // [picker setBccRecipients:bccRecipients];

    // Attach an image to the email
    UIImage *myImage = YourImage;
    NSData *myData = UIImagePNGRepresentation(myImage);
    [picker addAttachmentData:myData mimeType:@"image/png" fileName:@"myImage.png"];

    // Fill out the email body text
    NSString *emailBody = @"My Pic";
    [picker setMessageBody:emailBody isHTML:NO];
    [self presentModalViewController:picker animated:YES];

    [picker release];
}

4) Implement the delegate method

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
    // Notifies users about errors associated with the interface
    switch (result)
    {
        case MFMailComposeResultCancelled:
            NSLog(@"Result: canceled");
            break;
        case MFMailComposeResultSaved:
            NSLog(@"Result: saved");
            break;
        case MFMailComposeResultSent:
            NSLog(@"Result: sent");
            break;
        case MFMailComposeResultFailed:
            NSLog(@"Result: failed");
            break;
        default:
            NSLog(@"Result: not sent");
            break;
    }
    [self dismissModalViewControllerAnimated:YES];
}

IPhone Custom Toolbar on Keyboard to Hide keyboard

2012-10-24T00:44:00.003-07:00

IPhone Custom Toolbar on Keyboard

MY requirement was to work on numeric keys not alphabets so i have used Numeric Pad on UITEXTFIELD and you all know that by default there is no button on numeric pad for hidden keyboard. You have to create Custom Button on ur numeric pad and call [numberTextField resignFirstResponder]; to hide numeric pad.

Solution
I have create a custom toolbar and have put two buttons on it 1) Apply and 2) Cancel. And created a method for both buttons.

- (void)viewDidLoad

{

[super viewDidLoad];

UIToolbar* numberToolbar = [[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];

numberToolbar.barStyle = UIBarStyleBlackTranslucent;

numberToolbar.items = [NSArray arrayWithObjects:

[[UIBarButtonItem alloc]initWithTitle:@"Cancel" style:UIBarButtonItemStyleBordered target:self action:@selector(cancelNumberPad)],

[[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil],

[[UIBarButtonItem alloc]initWithTitle:@"Apply" style:UIBarButtonItemStyleDone target:self action:@selector(doneWithNumberPad)],

nil];

[numberToolbar sizeToFit];

numberTextField.inputAccessoryView = numberToolbar;

}

-(void)cancelNumberPad{

[numberTextField resignFirstResponder];

numberTextField.text = @"";

}

-(void)doneWithNumberPad{

NSString *numberFromTheKeyboard = numberTextField.text;

[numberTextField resignFirstResponder];

}

Thats it ..
You can add Custom button on left side of 0 button.

2 UIPicker and 1 UILabel

Connect Datasource and delegate of both picker to file owner.

Source Code : https://github.com/zohaibbrohi/UIPickerView.git

NOTE:-

Sorry for naming convention. You can achieve this multi picker by using one pickerView and divide it in number of columns.

In numberOfComponentsInPickerView return how many columns you want in one pickerView.

Loaded nib but the view outlet was not set

2012-10-23T03:41:00.000-07:00

Loaded nib but the view outlet was not set

I was working on my iPhone project . And i copied Components from one nib file to another and when i run that project it gave this error. It happen when you copy nib components to another nib or sometime when you open new nib File.

Solution

Open the XIB file causing problems
Click on file's owner icon on the left bar (top one, looks like a yellow outlined box)
If you don't see the right-hand sidebar, click on the third icon above "view" in your toolbar. This will show the right-hand sidebar
In the right-hand sidebar, click on the third tab--the one that looks a bit like a newspaper
Under "Custom Class" at the top, make sure Class is the name of the ViewController that should correspond to this view. If not, enter it
In the right-hand sidebar, click on the last tab--the one that looks like a circle with an arrow in it
You should see "outlets" with "view" under it. Drag the circle next to it over to the "view" icon on the left bar (bottom one, looks like a white square with a thick gray outline
Save the xib and re-run

Inside Android Manifest

2012-10-22T13:11:00.002-07:00

The foundation for any Android application is the manifest file, AndroidManifest.xml in the root of your project. Here is where you declare what is inside your application—the activities, the services, and so on. You also indicate how these pieces attach themselves to the overall Android system; for example, you indicate which activity (or activities) should appear on the device’s main menu.
When you create your application, a starter manifest will be generated for you
automatically. For a simple application, offering a single activity and nothing else, the autogenerated manifest will probably work out fine, or perhaps require a few minor modifications. On the other end of the spectrum, the manifest file for the Android API demo suite is more than 1,000 lines long. Your production Android applications will probably fall somewhere in the middle.

Underneath the Manifest element

user permission elements: Indicate the permissions your application will need in order to function properly.
permission elements: Declare permissions that activities or services might require other applications to hold in order to use your application’s data or logic.
instrumentation elements: Indicate code that should be invoked on key system events, such as starting up activities, for the purposes of logging or monitoring.
uses-library elements: Hook in optional Android components, such as mapping services.
uses-sdk element: Indicates for which version of the Android SDK the application was built.
application element: Defines the guts of the application that the manifest describes.

Here’s an example:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.commonsware.android">
<uses-permission
android:name="android.permission.ACCESS_LOCATION" />
<uses-permission
android:name="android.permission.ACCESS_GPS" />
<uses-permission
android:name="android.permission.ACCESS_ASSISTED_GPS" />
<uses-permission
android:name="android.permission.ACCESS_CELL_ID" />
<application>
...
</application>
</manifest>
In this example, the manifest has uses permission elements to indicate some device capabilities the application will need—in this case, permissions to allow the application to determine its current location. The contents of the application element will describe the activities, services, and whatnot that make up the bulk of the application itself.

Inside Android Project

2012-10-22T13:10:00.002-07:00

In this post I will share that what is inside the android project. When you open android project you will see many files and folder in it.

Src

In this folder you will see java files. Whatever you will work in java you will do in this folder.

Gen

This is generated java file and you will see R.java file in this folder. There is nothing to do with this file when you open this file you will see on the top it says that DO NOT MODIFY. Whenever you will add components or anything in android using XML then it will added in this folder ( source code will be generated In this file) and after adding component to this folder you can easily bind that component with java (through R.java file) and can do whatever you like to do with that component.

Assets

A folder that holds other static files you wish packaged with the application for deployment onto the device.

Res

In this resource folder you will see drawable-hdpi, drawable-ldpi, drawable-mdpi, layout and values folder. Let’s talk about layout first. You will see main.xml file in layout and in this file you can make layout or you can say UI of android using XML. In Values folder there is string.xml file. This file help to make anything global ( means it can be use everywhere in application). If your project name is ABC and you want to use it anywhere in your project just add you project name ( p_name = ABC) now whenever you will call p_name you will see ABC and can easily change it(no need to change this name everywhere). Now let talk about drawable. If you want to add any picture in you project you will insert in this folder. But why three folder of drawable? High resolution pictures goes in hdpi, medium resolution in mdpi and low in ldpi.

Manifest.xml

An XML file describing the application being built and which components—activities, services, and so on—are being supplied by that application.

Default.properties and local.properties

Property files used by the Ant build script.

Res/drawable/:For images (PNG, JPEG, etc.).

Res/layout/:For XML-based UI layout specifications.

Res/menu/:For XML-based menu specifications.

Res/raw/:For general-purpose files (e.g., a CSV file of account

information).

Res/values/:For strings, dimensions, and the like.

Res/xml/:For other general-purpose XML files you wish to ship.

AlertVIew in iphone with 2 buttons OK/YES/DELETE and NO/CANCEL .
// 2 Buttons
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Wait" message:@"Are you sure you want to delete this. This action cannot be undone" delegate:self cancelButtonTitle:@"Delete" otherButtonTitles:@"Cancel", nil];
[alert show];

Performing Action on Both Buttons i.e Delete and Cancel.
buttonIndex 0 for Delete
buttonIndex 1 for Cancel

- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex {
if (buttonIndex == 0) {

Enumeration

2011-05-14T15:03:00.000-07:00

Enumeration are declared using enum keyword. Enumeration are distinct type consisting of a set of names that are constant.
For example we know that days in week are constant so we can use enum for days and month also.
Each enum type has a corresponding integral type called the underlying type of the enum
type. This underlying type must be able to represent all the enumerator values defined in
the enumeration. An enum declaration may explicitly declare an underlying type of byte,
sbyte, short, ushort, int, uint, long, or ulong. Note that char cannot be used as an underlying
type. An enum declaration that does not explicitly declare an underlying type has an
underlying type of int.

Example:-

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace test_practise
{
public enum Days { Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday }
class Program
{
static void Main(string[] args)
{
Days day = Days.Monday;
Console.WriteLine((int)day);
Console.WriteLine(day);
Console.ReadLine();
}
}
}

You will see output 0. You can change the value of Monday from 0 to 1 by assigning value to Monday

public enum Days { Monday=1, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday }

Interface

2011-03-01T16:22:00.000-08:00

Interface is a comunicating media between two mediums. In c# multiple inheritance is not allowed that's why interface are used to fulfil the needs of multiple inheritance. As c# does not support multiple inheritance then it is necessary that the class can inherit the behaviour of more than one class, that's what interface provides us. In multiple inheritance we had a problem that if a class has two base class and both have some same methods then which method to call. Classes can inherit multiple interface.
Interface are contract of rules that a class which inherits it must follow(i.e must implement the method which are defined in interface). Interface contains method that do not contain any implementation just contain declaration of that method and the class which inherits it must implement those method. Interfaces can contain properties, indexers, and events but interface cannot contains field and interface cannot be instantiate.

Example

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace blog
{
   class Program
   {
   static void Main(string[] args)
   {
   circle objc = new circle();
   objc.fill();
   square objs = new square();
   objs.fill();
   line objl = new line();
   objl.draw();
   Console.ReadKey();
   }
   }
   interface fill
   {
   void fill();
   }
   class shapes {
   public void draw() {
   Console.WriteLine("shape Draw");
   }
   }
   class circle : shapes,fill {
   public void fill() {
   Console.WriteLine("Circle Fill");
   }
   }
   class square : shapes, fill {
   public void fill() {
   Console.WriteLine("Square Fill");
   }
   }
   class line : shapes {
   }
}

Mathematical Table

Mathematical Table
Lets make a Program that take input and will show mathematical table.

static void Main(string[] args)
   {
   int table;
   Console.WriteLine("Enter Table Number");
   table = Convert.ToInt32(Console.ReadLine());
   for (int i = 1; i < 13; i++)
   {
   Console.WriteLine(table + " x " + i + " = " + i * table);
   }
   Console.ReadKey();
   }

Lets make another program that will show mathematical table from 1 to 12.

static void Main(string[] args)
   {
   for (int i = 1; i < 11; i++)
   for (int j = 1; j < 13; j++)
   Console.WriteLine(i + " x " + j + " = " + i * j);

   Console.ReadKey();
   }

Factorial Program

2011-02-16T06:26:00.000-08:00

Factorial Program
Lets make a factorial program using FOR loop. First of all we should understand what's the mechanism of factorial. Factorial number are those number which multiply themselves by its lower number. If you want to find out factorial of 4 that will be ( 4 x 3 x 2 x 1 ) 24.

static void Main(string[] args)
   {
   int num;
   int result=1;
   Console.WriteLine("Enter Any Number To Find its Factorial");
   num = Convert.ToInt32(Console.ReadLine());
   for (int i = num; i > 1 ; i--)
   result *= i;
   Console.WriteLine("Factorial of "+ num +" is " + result);
   Console.ReadKey();

   }
