Using the social.framework is real simple on iOS 6.0. Apple only refers to their reference, so I decided to show the code snippet example. To change between twitter and Sina Weibo, just use the types: SLServiceTypeSinaWeibo SLServiceTypeTwitter. It just takes 10 lines of code. If you used the Twitter.framework, you can remove it and replace your Twitter code with the following code. The Social.framework will manage all social networks moving forward.

if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {

SLComposeViewController *socialSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];

[socialSheet setInitialText:@"posted from @PhotoTable"];

[socialSheet addImage:image];

[socialSheet setCompletionHandler:^(SLComposeViewControllerResult result) {

NSLog(@"Result: %d", result);

}];

[self presentViewController:socialSheet animated:YES completion:^ {

}];

}
