Facebook/Twitter API Integration in iOS6 - iPhone

You need to add Social.framework in your project.
Add  ---  #import "Social/Social.h"

You can create 3 type of service:

SLServiceTypeTwitter;

SLServiceTypeFacebook;

SLServiceTypeSinaWeibo;

For Facebook -

SLComposeViewController *facebookController=[SLComposeViewControllercomposeViewControllerForServiceType:SLServiceTypeFacebook];

if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])

{

        SLComposeViewControllerCompletionHandler __block completionHandler=^(SLComposeViewControllerResultresult){

        

        [facebookController dismissViewControllerAnimated:YES completion:nil];

        

        switch(result){

        case SLComposeViewControllerResultCancelled:

        default:

        {

            NSLog(@"Result Cancelled");

            

        }

            break;

        case SLComposeViewControllerResultDone:

        {

            NSLog(@"Result Post Done");

        }

            break;

    }};

    

    [facebookController addImage:[UIImage imageNamed:@"yourImage.jpg"]];

    [facebookController setInitialText:@"Check out this cool IOS Blog"];

    [facebookController addURL:[NSURL URLWithString:@"http://vijaysinghadhikari.blogspot.in/"]];

    [facebookController setCompletionHandler:completionHandler];

    [self presentViewController: facebookController animated:YES completion:nil];
