Iphone郵件應用程序

Question

可以打開Iphone郵件應用程序而無需撰寫新消息？

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

此代碼不適合我。

我只需要在主屏幕上打開郵件應用程序。

感謝

PS對不起，我的英文））

-(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 
{ 
    switch (result) 
    { 
    case MFMailComposeResultCancelled: 
     UIAlertView *ErrorAlert = [[UIAlertView alloc] initWithTitle:@"Canceled !!" 
         message:@"Mail sending cancelled." delegate:nil 
         cancelButtonTitle:@"OK" otherButtonTitles:nil, nil]; 
     [ErrorAlert show]; 
     [ErrorAlert release]; 
     break; 
    case MFMailComposeResultSaved: 
     UIAlertView *ErrorAlert = [[UIAlertView alloc] initWithTitle:@"Saved" 
            message:@"Mail saved to Drafts." delegate:nil 
            cancelButtonTitle:@"OK" otherButtonTitles:nil, nil]; 
     [ErrorAlert show]; 
     [ErrorAlert release]; 
     break; 
    case MFMailComposeResultSent:

        message:@"Thank you for recommending us to your friends via Email." 
        delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil]; 
     [ErrorAlert show]; 
     [ErrorAlert release]; 
     break; 
    case MFMailComposeResultFailed: 
     UIAlertView *ErrorAlert = [[UIAlertView alloc] initWithTitle:@"Error !!" 
            message:@"Failed to send mail." delegate:nil

     [ErrorAlert show]; 
     [ErrorAlert release]; 
     break; 
    default: 
     UIAlertView *ErrorAlert = [[UIAlertView alloc] initWithTitle:@"Error !!"

     break; 
} 
[self becomeFirstResponder]; 
[self dismissModalViewControllerAnimated:YES];
