嘗試呈現MFMailComposeViewController時應用程序崩潰

-1

我想在我的應用程序中呈現MFMailComposeViewController以從我的應用程序發送郵件。每當我調用該方法來呈現郵件撰寫我的應用程序崩潰，下面崩潰日誌：嘗試呈現MFMailComposeViewController時應用程序崩潰

Assertion failure in -[UICGColor encodeWithCoder:], /SourceCache/UIKit/UIKit-2372/UIColor.m:1191 

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Only support RGBA or the White color space, this method is a hack.' 
First throw call stack:

libc++abi.dylib: terminate called throwing an exception

下面是我使用的代碼：

// Send email 
- (void) emailAction 
{ 

    MFMailComposeViewController* controller = [[MFMailComposeViewController alloc] init]; 
    controller.mailComposeDelegate = self; 
    [controller setSubject:@"FavePlates app"]; 

    UIImage *ImageToShare = selectedDishImageView.image; 
    NSData *myData = UIImagePNGRepresentation(ImageToShare); 
    [controller addAttachmentData:myData mimeType:@"image/png" fileName:[NSString stringWithFormat:@"%@",ImageToShare]]; 

    NSString * msgBody = [NSString stringWithFormat:@"%@", Check Out]; 
    [controller setMessageBody:msgBody 
         isHTML:NO]; 
    if (controller) { 
     [self presentModalViewController:controller 
           animated:YES]; 
    } 

} 

    - (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error 
    { 
     NSString *messageBody= [[NSString alloc] init]; 
     switch (result) 
     { 
      case MFMailComposeResultCancelled: 
       DLog(@"Mail cancelled: you cancelled the operation and no email message was queued."); 
       [self dismissViewControllerAnimated:YES 
             completion:nil]; 
       messageBody = @"You cancelled sending message"; 
       break; 

      case MFMailComposeResultSaved: 
       DLog(@"Mail saved: you saved the email message in the drafts folder."); 
       [self dismissViewControllerAnimated:YES 
             completion:nil]; 
       messageBody = @"Mail saved: you saved the email message in the drafts folder'"; 
       break; 

      case MFMailComposeResultSent: 
       DLog(@"Mail send: the email message is queued in the outbox. It is ready to send."); 
       [self dismissViewControllerAnimated:YES 
             completion:nil]; 
       messageBody = @"Mail has been sent"; 
       [self mailSent]; 
       break; 

      case MFMailComposeResultFailed: 
       DLog(@"Mail failed: the email message was not saved or queued, possibly due to an error."); 
       [self dismissViewControllerAnimated:YES 
             completion:nil]; 
       messageBody = @"Email sending failed"; 
       break; 

      default: 
       DLog(@"Mail not sent."); 
       [self dismissViewControllerAnimated:YES 
             completion:nil]; 
       break; 
     } 

    }

u能共享代碼...？ –

您是否錯誤地複製並粘貼了此內容，您在關閉之前缺少關閉「關閉」 NSString * msgBody = [NSString stringWithFormat：@「％@，Check Out]; – CW0007007

您是否在代碼中的任何位置使用ColorWithPatternImage？ – GenieWanted

請檢查你的代碼下面一行：

[controller addAttachmentData:myData mimeType:@"image/png" fileName:[NSString stringWithFormat:@"%@",ImageToShare]];

有替換[NSString stringWithFormat:@"%@",ImageToShare]帶有一些文本或圖像名稱ImageToShare是圖像的對象

那麼它看起來像：

[controller addAttachmentData:myData mimeType:@"image/png" fileName:"YourImageFileName"];

和

請更換行：

[self presentModalViewController:controller animated:YES];

與

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