應用程序凍結後發送鳴叫

Question

嗨我有一個iOS應用程序中的兩個UIButtons。一種是發佈到twitter，另一種是發佈到Facebook。 facebook按鈕的工作原理非常完美，但推文封閉了我的一些問題，推特表會隨着填充的文本打開，但需要點擊兩下取消按鈕才能解除。如果我點擊發送推文將被髮送，工作表被解散，但我的應用程序凍結，並變得沒有響應。我已經包含的代碼

- (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); 

}]; 
} 

Answer 1

您呈現的ViewController 「myTweet」

[self presentViewController:myTweet animated:YES completion:nil]; 

兩個位，但沒有解僱...語句在completionHandler

[self dismissViewControllerAnimated:YES completion:nil];
