触发通过iOS6的“推特表”

Question

我想触发通过iOS6的内置的“鸣叫表”

我希望将用户的tweet东西之后的特定动作的用户鸣叫后动作在用户点击其“发送”按钮后触发一个方法。

或者，如果我可以从iOS获得一些确认发布tweet的消息，那么我想要触发该方法。

这些选项都可能吗？在用户发布推文后是否有不同的首选方式来触发操作？

Answer 1

使用完成处理程序。看下面的代码示例。

SLComposeViewController *tweetSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter]; 
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; 
    } 

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

-(void)shareViewTwitter:(NSString*)str 
{ 
    TWTweetComposeViewController *twitter = [[TWTweetComposeViewController alloc] init]; 

    // Optional: set an image, url and initial text 

    [twitter setInitialText:@"Some Text"]; 

    // Show the controller 
    [self presentModalViewController:twitter animated:YES]; 

    // Called when the tweet dialog has been closed (Here your Action will be triggered) 
    twitter.completionHandler = ^(TWTweetComposeViewControllerResult result) 
    { 
     NSString *title = @"Tweet Status"; 
     NSString *msg; 

     if (result == TWTweetComposeViewControllerResultCancelled) 
// Your Action 

      msg = @"Tweet compostion was canceled."; 
     else msg = @"Tweet composition completed."; // Your Action 

     // Show alert to see how things went... 
     UIAlertView* alertView = [[UIAlertView alloc] initWithTitle:title message:msg delegate:self cancelButtonTitle:@"Okay" otherButtonTitles:nil]; 
     [alertView show]; 

     // Dismiss the controller 

     [self dismissModalViewControllerAnimated:YES]; 

    }; 

}
