iphone - 无法关闭 iPhone 中的电子邮件编辑器 View ？

Question

我是 iPhone 开发新手。我创建了一个基于选项卡栏的应用程序。首先，我希望显示电子邮件编辑器。我可以显示它，但取消和发送按钮不起作用，我不知道哪里出了问题。请帮助我。这是我的代码。

- (void)viewDidLoad 
{
    [super viewDidLoad];
    [self displayComposerSheet];    
}

-(void)displayComposerSheet 
{
    picker = [[MFMailComposeViewController alloc] init];

   [[picker navigationBar] setTintColor:[UIColor blackColor]];

   picker.mailComposeDelegate = self;

   if ([MFMailComposeViewController canSendMail]) 
   {

            [picker setToRecipients:[NSArray arrayWithObjects:@"name@gmail.com",nil]];

            [picker setSubject:@"Sample"];

   }
   [self.view addSubview:picker.view];
   [self presentModalViewController:picker animated:YES];

}

 - (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error 
{

    [self dismissModalViewControllerAnimated:YES];

 }

Answer 1

您正在两次呈现邮件编辑器。

删除该行:

[self.view addSubview:picker.view];

并将下一行替换为:

[self.navigationController presentModalViewController:picker animated:YES];
