社会框架：

share Fb or Twitter

- (IBAction)socialSheet:(id)sender {



       // create Facebook controller
        SLComposeViewController *socialController = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];

        // add initial text
        [socialController setInitialText:@"Hello Facebook!"];

        // add an image for you optional 
        [socialController addImage:[UIImage imageNamed:@"picture.jpg"]];

        // add a URL for you optional 
        [socialController addURL:[NSURL URLWithString:@"http://wpguru.co.uk"]];

        // present controller
        [self presentViewController:socialController animated:YES completion:nil];
    }
