iOS - Twitter and Facebook

---

Twitter has been integrated in iOS 5.0 and Facebook has been integrated in iOS 6.0. Our tutorial focuses on using the classes provided by Apple and the deployment targets for Twitter and Facebook are iOS 5.0 and iOS 6.0 respectively.

Steps Involved

Step 1 − Create a simple view-based application.

Step 2 − Select your project file, then select targets and then add Social.framework and Accounts.framework in choose frameworks.

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

Step 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

Step 5 − Update ViewController.m as follows −

#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 we run the application and click facebookPost, we will get the following output −

When we click twitterPost, we will get the following output −
