iOS-Twitter and Facebook

Introduction

Twitter has been integrated into iOS 5.0, while Facebook has been integrated into iOS 6.0. This tutorial focuses on how to deploy Twitter and Facebook in iOS 5.0 and iOS 6.0 using the classes provided by Apple.

Example Steps

1. Create a simple View-based application.

2. Select the project file, then choose "targets," and add the Social.framework and Accounts.framework in the choose frameworks section.

3. Add two buttons named facebookPost and twitterPost, and create ibActions for them.

4. Update ViewController.h as follows:

   #import <Social/Social.h>
   #import <Accounts/Accounts.h>
   #import <UIKit/UIKit.h>
   
   @interface ViewController : UIViewController
   
   -(IBAction)twitterPost:(id)sender;
   -(IBAction)facebookPost:(id)sender;
   
   @end
   

5. Update ViewController.m as shown below:

   #import "ViewController.h"
   
   @interface ViewController ()
   
   @end
   
   @implementation ViewController
   
   - (void)viewDidLoad
   {
       [super viewDidLoad];
   }
   
   - (void)didReceiveMemoryWarning
   {
       [super didReceiveMemoryWarning];
       // Dispose of any resources that can be recreated.
   }
   
   -(IBAction)facebookPost:(id)sender{
   
      SLComposeViewController *controller = [SLComposeViewController 
      composeViewControllerForServiceType:SLServiceTypeFacebook];
      SLComposeViewControllerCompletionHandler myBlock = 
      ^(SLComposeViewControllerResult result){
             if (result == SLComposeViewControllerResultCancelled)
             {                
               NSLog(@"Cancelled");                
             } 
             else                
             {
               NSLog(@"Done");
             }
             [controller dismissViewControllerAnimated:YES completion:nil];
           };
      controller.completionHandler =myBlock;        
      //Adding the Text to the facebook post value from iOS
      [controller setInitialText:@"My test post"];        
      //Adding the URL to the facebook post value from iOS
      [controller addURL:[NSURL URLWithString:@"http://www.test.com"]];        
      //Adding the Text to the facebook post value from iOS
      [self presentViewController:controller animated:YES completion:nil];    
   }
   
   -(IBAction)twitterPost:(id)sender{
       SLComposeViewController *tweetSheet = [SLComposeViewController 
       composeViewControllerForServiceType:SLServiceTypeTwitter];
   

[tweetSheet setInitialText:@"My test tweet"];
[self presentModalViewController:tweetSheet animated:YES];
}

@end

Output

When running the application and clicking facebookPost, we will get the following output:
