ios - 用户通过 iOS6“推文表”发推文后触发动作

Question

我想在用户通过 iOS6 的内置“推文表”发布推文后触发特定操作

我想在用户点击其“发送”按钮后触发一个方法。

或者，如果我可以从 iOS 收到一些确认推文已成功发布，我想触发该方法。

这些选项中的任何一个都可能吗？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

-(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];

    };

}

使用完成处理程序。请参阅下面的代码示例。

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.");
        }];
    });
};
