iPhone 邮件应用程序

Question

是否可以打开 Iphone Mail 应用程序而无需撰写新邮件？

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"mailto:%@?subject=My Subject", _recipient]]];

此代码不适合我。

我只需在主屏幕上打开邮件应用程序。

谢谢

P.S 抱歉我的英语))

   -(void) EmailMethod
  {
    MFMailComposeViewController *picker=[[MFMailComposeViewController alloc]init]; 
picker.mailComposeDelegate = self;
    [picker setToRecipients:@"mailid@mymail.com"];
[picker setSubject:@"Place your subject of mail here."];
[picker setMessageBody:@"Place your body of mail here." isHTML:YES];
    [self presentModalViewController:picker animated:YES];      
  }

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