您可以轻松地将图像和文本发布到Facebook。 为此，您不必退出应用程序。 尝试这个：

- (void) postFacebook {

    if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {
        SLComposeViewController *fbSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
        [fbSheet setInitialText:@"Your Text here"];
        [fbSheet addImage:[UIImage imageNamed:@"Icon-144.png"]];
        [fbSheet addURL:[NSURL URLWithString:@"http://asdf.com"]];
        [[CCDirector sharedDirector] presentViewController:fbSheet animated:YES completion:nil];
    }
    else {

        UIAlertView *alertView = [[UIAlertView alloc]
                                  initWithTitle:@"Sorry!!!"
                                  message:@"You can't share on facebook right now, make sure your device has an internet connection and you have at least one facebook account setup in your device."
                                  delegate:self
                                  cancelButtonTitle:@"OK"
                                  otherButtonTitles:nil];
        [alertView show];
    }

}

对于高音扬声器，请执行以下操作：

- (void) callTwitter {

    if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter])
    {
        SLComposeViewController *tweetSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
        [tweetSheet setInitialText:@"Your text here"];
        [tweetSheet addImage:[UIImage imageNamed:@"Icon-144.png"]];
        [tweetSheet addURL:[NSURL URLWithString:@"http://asdf.com"]];
        [[CCDirector sharedDirector] presentViewController:tweetSheet animated:YES completion:nil];
    }
    else
    {
        UIAlertView *alertView = [[UIAlertView alloc]
                                  initWithTitle:@"Sorry!!!"
                                  message:@"You can't send a tweet right now, make sure your device has an internet connection and you have at least one twitter account setup in your device."
                                  delegate:self
                                  cancelButtonTitle:@"OK"
                                  otherButtonTitles:nil];
        [alertView show];
    }
}

不要忘记通过转到添加SOCIAL.FRAMEWORK

BuildPhases-> LinkBinaryWithLibraries

同样在ViewController中，不要忘记在顶部导入#import <Social/Social.h>

编辑：

好吧，我在SO中找到了这个：

NSString *myMessage = [NSString stringWithFormat:@"%@",
                       [self.txtAdreca.text stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

NSString *post = [NSString stringWithFormat:@"fb://publish/profile/me?text=%@",urlString];
BOOL canOpenURL = [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:post]];
if (canOpenURL) {
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:post]];
}

对于高音扬声器：

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"twitter://status?id=12345"]];

希望这可以帮助.. ：）
