Question

我有一个客户端在他的设备上测试应用程序，他正在使用带有iOS 6.1.3的iPhone 3GS。

该应用包含一个简单的部分，您可以在其中分享有关应用的信息等信息。

他报告的问题是，当邮件编辑器打开（presentViewController）时，应用程序会在显示后立即自动关闭邮件窗口。所以它会上升，然后再次直接下调，结果与您取消电子邮件的结果相同。

我完全不知道为什么只有这个singel测试仪报告了这个问题。它在模拟器iOS 6.1和7.0上运行良好，它在iPhone 4,4S和5等所有其他设备上运行良好。这是代码，也许我做错了3GS无法编译：

#pragma mark - Share to mail
// Share mail button
- (IBAction)shareTo_mail_BtnClicked:(id)sender
{
    [HUD showUIBlockingIndicatorWithText:@"Laddar mail"];

    // Email Subject
    NSString *emailTitle = PROMO_TEXT;
    // Email Content
    NSString *messageBody = SHARED_INFO_TEXT;

    // If mail account can't bee found
    if(![MFMailComposeViewController canSendMail]) {

        [HUD hideUIBlockingIndicator];

// Alert the user that no mail account is connected to the phone
            UIAlertView *warningAlert = [[UIAlertView alloc] initWithTitle:@"Ett fel inträffade" message:@"Kontrollera att du har ett mail-konto anslutet till telefonen." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
            [warningAlert show];
            return;

        }else {

            NSLog(@"Mail account found!");

        }

    MFMailComposeViewController *mc = [[MFMailComposeViewController alloc] init];
    mc.mailComposeDelegate = self;
    [mc setSubject:emailTitle];
    [mc setMessageBody:messageBody isHTML:NO];

    [self presentViewController:mc animated:YES completion:nil];
    [HUD hideUIBlockingIndicator];
}

// Mail did finish with result
- (void) mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
    switch (result)
    {
        case MFMailComposeResultCancelled:
            NSLog(@"Mail cancelled");
            break;
        case MFMailComposeResultSaved:
            NSLog(@"Mail saved");
            break;
        case MFMailComposeResultSent:
            NSLog(@"Mail sent");
            break;
        case MFMailComposeResultFailed:
            NSLog(@"Mail sent failure: %@", [error localizedDescription]);
            break;
        default:
            break;
    }

    // Close the Mail Interface
    [self dismissViewControllerAnimated:YES completion:nil];
}
