在iOS6中，TWTweetComposeViewController已被弃用。

Question

我的代码按预期工作，只是我需要摆脱这个警告信息。TWTeetComposeViewController在IOS6中已被弃用。有没有替代这个内置视图控制器的方法？

这是我的示例代码。

if ([TWTweetComposeViewController canSendTweet]) {
    // Initialize Tweet Compose View Controller
    TWTweetComposeViewController *vc = [[TWTweetComposeViewController alloc] init];
    // Settin The Initial Text
    [vc setInitialText:@"This tweet was sent using the new Twitter framework available in iOS 5."];
    // Adding an Image
    UIImage *image = [UIImage imageNamed:@"sample.jpg"];
    [vc addImage:image];
    // Adding a URL
    NSURL *url = [NSURL URLWithString:@"http://mobile.tutsplus.com"];
    [vc addURL:url];
    // Setting a Completing Handler
    [vc setCompletionHandler:^(TWTweetComposeViewControllerResult result) {
        [self dismissModalViewControllerAnimated:YES];
    }];
    // Display Tweet Compose View Controller Modally
    [self presentViewController:vc animated:YES completion:nil];
} else {
    // Show Alert View When The Application Cannot Send Tweets
    NSString *message = @"The application cannot send a tweet at the moment. This is because it cannot reach Twitter or you don't have a Twitter account associated with this device.";
    UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Oops" message:message delegate:nil cancelButtonTitle:@"Dismiss" otherButtonTitles:nil];
    [alertView show];
}

你在哪里看到那个TWTeetComposeViewController的？？http://developer.apple.com/library/ios/#documentation/Twitter/Reference/TWTweetSheetViewControllerClassRef/Reference/Reference.html - Martin

在iOS 5和iOS 6之间使用社交网络有一些变化。
1. 关于库：在iOS 6中，我们使用Social框架代替Twitter框架。
2. 我们使用SLComposeViewController代替TWTweetComposeViewController。
3. 请参考以下代码比较一些API：

if([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter]) {

        SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];

        SLComposeViewControllerCompletionHandler myBlock = ^(SLComposeViewControllerResult result){
            if (result == SLComposeViewControllerResultCancelled) {

                NSLog(@"Cancelled");

            } else

            {
                NSLog(@"Done");
            }

            [controller dismissViewControllerAnimated:YES completion:Nil];
        };
        controller.completionHandler =myBlock;

        //Adding the Text to the facebook post value from iOS
        [controller setInitialText:@"Test Post from mobile.safilsunny.com"];

        //Adding the URL to the facebook post value from iOS

        [controller addURL:[NSURL URLWithString:@"http://www.mobile.safilsunny.com"]];

        //Adding the Image to the facebook post value from iOS

        [controller addImage:[UIImage imageNamed:@"fb.png"]];

        [self presentViewController:controller animated:YES completion:Nil];

    }
    else{
        NSLog(@"UnAvailable");
    }

只有一点点的区别，但它们更重要。

是的，在iOS 6上应该使用Social Framework。这要归功于现在在iOS上存在的Facebook集成。你将能够从那里使用Twitter和Facebook。
