    // Initialize Activity View Controller
    UIActivityViewController *vc = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];

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

Add social framework. Import in your view controller.

SLComposeViewController *socialVc=[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
NSData *data = UIImageJPEGRepresentation(self.defaultImageView.image, 1.0);
[socialVc addImage:[UIImage imageWithData:data]];


[socialVc setInitialText:[NSString    stringWithFormat:@"%@",self.captionTextFeild.text]];
[socialVc addURL:[NSURL URLWithString:@"via www.coderit.com"]];
[self.navigationController presentViewController:socialVc animated:YES completion:nil];
