Question

我是新手，

我在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];
}

但是当我点击控制器中的发送按钮时，我收到错误，

2016-09-05 14：55：24.488 mailDemo [1276：104171] viewServiceDidTerminateWithError：错误 Domain = _UIViewServiceInterfaceErrorDomain Code = 3“（null）” UserInfo = {Message = Service Connection Interrupted} 2016-09-05 14：55：24.989 mailDemo [1276：104171]试图驳回演示文稿控制器在转换时已经。（＆lt; _UIFullscreenPresentationController：0x7fe35b52d2a0＆gt;）2016-09-05 14：55：24.991 mailDemo [1276：104171] transitionViewForCurrentTransition 未设置，演示控制器在期间被解雇介绍？（＆lt; _UIFullscreenPresentationController：0x7fe35b52d2a0＆gt;）

问题是什么？

Answer 1

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

Answer 2

模拟器不支持方法和设备不登录邮件，这种方法没有任何响应。

替换此方法::

- (void)sendMail:(id)sender {


    if (![MFMailComposeViewController canSendMail]) {
        NSLog(@"Mail services are not available.");
        return;
    }
    else{
            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];
        }
}

Answer 3

MFMailComposeViewController不适用于模拟器。如果您在真实设备中尝试相同的代码，它将起作用。您的代码没有任何问题。

MailCompositionService意外退出ios
