嗨,我在iOS应用程序中有两个UIButton.一个是发布到Twitter,第二个是发布到Facebook. Facebook按钮工作得很好但是推文给我留下了一些问题,推文表将打开填充文本,但需要两次点击取消按钮才能解除.如果我点击发送,将发送推文并且表单被解雇,但我的应用程序冻结并变得无法响应.我已经包含了两位代码
- (IBAction)postTweet:(id)sender { // if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter]){ myTweet = [[SLComposeViewController alloc]init]; myTweet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter]; NSString *tweetString = [[NSString alloc]initWithFormat:@"%@\n%@\nvia @ValuatorApp", pdOne.text, pdTwo.text]; [myTweet setInitialText:tweetString]; [myTweet addURL:[NSURL URLWithString:@"http://sjb007.me/TheValuator"]]; [self presentViewController:myTweet animated:YES completion:nil]; // } [myTweet setCompletionHandler:^(SLComposeViewControllerResult result) { NSString *output = [[NSString alloc]init]; switch (result) { case SLComposeViewControllerResultCancelled: output = @"Twitter Post Cancelled"; break; case SLComposeViewControllerResultDone: output = @"Twitter post Succesful"; break; default: break; } NSLog(@"%@",output); }]; } - (IBAction)postFacebook:(id)sender { // if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]){ myTweet = [[SLComposeViewController alloc]init]; myTweet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook]; if (pd3 != 0) { NSString *facebookString = [[NSString alloc]initWithFormat:@"%@\n%@\n%@", pdOne.text,pdTwo.text, pdThree.text]; [myTweet setInitialText:facebookString]; } else if (pd3 == 0){ NSString *facebookString = [[NSString alloc]initWithFormat:@"%@\n%@\n", pdOne.text,pdTwo.text]; [myTweet setInitialText:facebookString]; } // [myTweet addImage:[UIImage imageNamed:@"Photo Jun 02, 22 46 37.jpg"]]; [myTweet addURL:[NSURL URLWithString:@"http://sjb007.me/TheValuator"]]; [self presentViewController:myTweet animated:YES completion:nil]; // } [myTweet setCompletionHandler:^(SLComposeViewControllerResult result) { NSString *output = [[NSString alloc]init]; switch (result) { case SLComposeViewControllerResultCancelled: output = @"Facebook Post Cancelled"; break; case SLComposeViewControllerResultDone: output = @"Facebook post Succesful"; break; default: break; } NSLog(@"%@",output); }]; }
您正在展示ViewController“myTweet”
[self presentViewController:myTweet animated:YES completion:nil];
但是你的completionHandler中没有解雇……声明
[self dismissViewControllerAnimated:YES completion:nil];
