邮件和邮件不会从警报视图中撤销 [英] Mail and Message not Dismissing from Alert View

问题描述

我有一个UIAlertView启动一个电子邮件和一个消息屏幕。当用户点击警报的按钮时，这两个视图都会打开，但是它们不会关闭。

我尝试添加：

$ （MFMailComposeViewController *）控件didFinishWithResult：（MFMailComposeResult）结果错误：（NSError *）错误{
[self dismissModalViewControllerAnimated：YES] ;
}

到该类的正文，但是没有帮助。 p>

这是电子邮件的显示方式：

  [viewController presentViewController：email动画：YES完成：nil]; 
  

编辑这是我用来显示电子邮件的整个代码：

  //发送电子邮件... 
  - （void）sendEmail {
 
 / / mail composer 
 Class mailClass =（NSClassFromString（@MFMailComposeViewController））; 
 if（mailClass！= nil）{
 if（[mailClass canSendMail]）{
 
 //从App代理获取当前视图控制器
 apptester_appDelegate * appDelegate =（apptester_appDelegate *）[[UIApplication sharedApplication] delegate]; 
 UIViewController * viewController = [appDelegate getViewController]; 
 
 MFMailComposeViewController * email = [[MFMailComposeViewController alloc] init]; 
 email.mailComposeDelegate = self; 
 
 //导航栏颜色取决于iOS7或更低版​​本... 
 if（floor（NSFoundationVersionNumber）< = NSFoundationVersionNumber_iOS_6_1）{
 [[email navigationBar] setTintColor：[UIColor黑色]; 
} else {
 [[email navigationBar] setBarTintColor：[UIColor blackColor]]; 
} 
 
 //显示模型视图... 
 [viewController presentViewController：电子邮件动画：YES完成：nil]; 
 
} 
} 
} 
  

有没有人否则会出现此错误？

这可能并不相关，但这个应用程序有一个标签栏。

解决方案

确保已设置邮件控制器委托人

  mail.mailComposeDelegate = viewController; 
  

另请尝试，

  [viewController.tabBarController presentViewController：email animated：YES completion：nil]; 
  

您是否尝试使用此方法并传递控制器而不是self：

$ b $ （MFMailComposeViewController *）控制器didFinishWithResult：（MFMailComposeResult）结果错误：（NSError *）错误
{
[controller dismissViewControllerAnimated：YES completion：nil];
}

谢谢！

I have a UIAlertView that launches an email and a messages screen. When a user clicks on the Alert's button, both views open, however, they do not close.

I have a tried adding:

-(void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error {
    [self dismissModalViewControllerAnimated:YES];
}

to the body of the class, however, it did not help.

Here is how the email is presented:

    [viewController presentViewController:email animated:YES completion:nil];

Edit Here is the entire code I am using to present the email:

//send email...
-(void)sendEmail{

    //mail composer
    Class mailClass = (NSClassFromString(@"MFMailComposeViewController"));
    if(mailClass != nil){
        if([mailClass canSendMail]){

            //get the current view controller from the App Delegate
            apptester_appDelegate *appDelegate = (apptester_appDelegate *)[[UIApplication sharedApplication] delegate];
            UIViewController *viewController = [appDelegate getViewController];

            MFMailComposeViewController *email = [[MFMailComposeViewController alloc] init];
            email.mailComposeDelegate = self;

            //navigation bar color depends on iOS7 or lower...
            if(floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1){
                [[email navigationBar] setTintColor:[UIColor blackColor];
            }else{
                [[email navigationBar] setBarTintColor:[UIColor blackColor]];
            }

            //show the model view...
            [viewController presentViewController:email animated:YES completion:nil];

        }
    }
}

Has anyone else experienced this error?

This may not be relevant, but this app has a tab bar.

解决方案

Make sure you have set delegate for mail controller

   mail.mailComposeDelegate = viewController;

Also try this as well,

    [viewController.tabBarController presentViewController:email animated:YES completion:nil];

Have you try this method and pass "controller" instead of self:

   -(void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
    {
       [controller dismissViewControllerAnimated:YES completion:nil];
    }

Thanks!
