ios - MailCompositionService 意外退出 ios

Question

我是新手，

我的 viewController 中有这段代码，

- (void)sendMail:(id)sender {
    NSArray *to = [NSArray arrayWithObjects:@"rayjada11@gmail.com", nil];

    mailComposer = [[MFMailComposeViewController alloc] init];
    mailComposer.mailComposeDelegate = self;
    [mailComposer setToRecipients:to];
    [mailComposer setSubject:@"Test Mail"];
    [mailComposer setMessageBody:@"Testing message body" isHTML:NO];
    [self presentModalViewController:mailComposer animated:YES];
}



#pragma mark - mail compose delegate
-(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error {
    if(result) {
        NSLog(@"Result = %d", result);
    }
    if(error) {
        NSLog(@"Error = %@", error);
    }
    [self dismissModalViewControllerAnimated:YES];
}

但是当我点击我的 Controller 中的发送按钮时，我得到了这样的错误，

2016-09-05 14:55:24.488 mailDemo[1276:104171] viewServiceDidTerminateWithError: Error Domain=_UIViewServiceInterfaceErrorDomain Code=3 "(null)" UserInfo={Message=Service Connection Interrupted} 2016-09-05 14:55:24.989 mailDemo[1276:104171] Trying to dismiss the presentation controller while transitioning already. (<_UIFullscreenPresentationController: 0x7fe35b52d2a0>) 2016-09-05 14:55:24.991 mailDemo[1276:104171] transitionViewForCurrentTransition is not set, presentation controller was dismissed during the presentation? (<_UIFullscreenPresentationController: 0x7fe35b52d2a0>)

问题是什么？

您的代码没有任何问题。MFMailComposeViewController 不适用于模拟器，请在真实设备中尝试相同的代码。
