我通过以下方式向 Twitter 发布消息：

 if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter])
{



//  Create an instance of the Tweet Sheet
SLComposeViewController *tweetSheet = [SLComposeViewController
                                       composeViewControllerForServiceType:
                                       SLServiceTypeTwitter];

// Sets the completion handler.  Note that we don't know which thread the
// block will be called on, so we need to ensure that any UI updates occur
// on the main queue
tweetSheet.completionHandler = ^(SLComposeViewControllerResult result) {
    switch(result) {
            //  This means the user cancelled without sending the Tweet
        case SLComposeViewControllerResultCancelled:
            break;
            //  This means the user hit 'Send'
        case SLComposeViewControllerResultDone:
            break;
    }

    //  dismiss the Tweet Sheet
    dispatch_async(dispatch_get_main_queue(), ^{
        [self dismissViewControllerAnimated:NO completion:^{
            NSLog(@"Tweet Sheet has been dismissed.");
        }];
    });
};

//  Set the initial body of the Tweet
[tweetSheet setInitialText:@"Download Cleverly at "];

//  Adds an image to the Tweet.  For demo purposes, assume we have an
//  image named 'larry.png' that we wish to attach
if (![tweetSheet addImage:[UIImage imageNamed:@"iTunesArtwork120.png"]]) {
    NSLog(@"Unable to add the image!");
}

//  Add an URL to the Tweet.  You can add multiple URLs.
if (![tweetSheet addURL:[NSURL URLWithString:@"https://itunes.apple.com/us/app/cleverly/id703006076?ls=1&mt=8"]]){
    NSLog(@"Unable to add the URL!");
}

//  Presents the Tweet Sheet to the user
[self presentViewController:tweetSheet animated:NO completion:^{
    NSLog(@"Tweet sheet has been presented.");
}];
}
}

我想运行这个方法：

NSInteger highScore = [[NSUserDefaults standardUserDefaults] integerForKey:@"SharingsLeft"];
if (highScore != 999999999) {
[[NSUserDefaults standardUserDefaults] setInteger:highScore + 5 forKey:@"SharingsLeft"];
[self.SendCounter setTitle:[NSString stringWithFormat:@"%ld", (long)highScore] forState:UIControlStateNormal];

仅当用户实际发布推文时。但是，当推文发布或用户按下“发布”按钮时，该块中没有任何方法可以通知我。

tweetSheet.completionHandler = ^(SLComposeViewControllerResult result) {
    switch(result) {
            //  This means the user cancelled without sending the Tweet
        case SLComposeViewControllerResultCancelled:
            break;
            //  This means the user hit 'Send'
        case SLComposeViewControllerResultDone:
            break;
    }

};

如果您阅读正确，SLComposeViewControllerResultDone是当用户为工作表按下发送/发布时，您可以在此处添加您想要在用户成功发布时调用的方法调用

 };

完全同意但丁
