ios - 用户通过 iOS6 "tweet sheet"发推后触发一个 Action

Question

我想在用户通过 iOS6 的内置“tweet sheet”发布推文后触发特定操作

我想在用户点击“发送”按钮后触发一个方法。

或者，如果我可以从 iOS 收到一些关于推文已成功发布的确认信息，那么我想触发该方法。

这两个选项中的任何一个都可行吗？在用户发布推文后，是否有一种不同的首选方式来触发操作？

Answer 1

-(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];

    };

}
