DismissModaViewController上的郵件編輯器不起作用

Question

當我完成屏幕截圖並嘗試在應用中發送屏幕截圖時遇到問題。通常情況下，發送文本時可以很好地工作，但一旦發送屏幕截圖，無論取消還是發送電子郵件，屏幕都不會消失。我可否知道這有什麼問題？

這是我的代碼。非常感謝你。

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { 

     if (buttonIndex == 0) { 

     UIGraphicsBeginImageContext(self.view.frame.size); 
     [self.view.layer renderInContext:UIGraphicsGetCurrentContext()]; 
     UIImage * image = UIGraphicsGetImageFromCurrentImageContext(); 
     UIGraphicsEndImageContext(); 

     NSData * imageData = UIImageJPEGRepresentation(image, 1.0); 

     if ([MFMailComposeViewController canSendMail]) { 
      MFMailComposeViewController * mailComposer = [[[MFMailComposeViewController alloc] init] autorelease]; 
      mailComposer.delegate = self; 
      [mailComposer addAttachmentData:imageData mimeType:@"image/jpeg" fileName:@"attachment.jpg"]; 

      /* Configure other settings */ 

      [self presentModalViewController:mailComposer animated:YES]; 
     } 
    } 
} 
- (void)mailComposeController:(MFMailComposeViewController*)controller{ 
    [self dismissModalViewControllerAnimated:YES]; 
}

你需要實現的委託方法是mailComposeController:didFinishWithResult:error:，不mailComposeController:。詳情請參閱the documentation。
