iphone - MFMailComposer 在 io6 横向模式下不工作

Question

if ([MFMailComposeViewController canSendMail]) {
    MFMailComposeViewController * mailComposeController=[[MFMailComposeViewController alloc]init];
    mailComposeController.mailComposeDelegate = self;
  //  mailComposeController.wantsFullScreenLayout = NO;
    [mailComposeController setSubject:@"WallPaperApp."];
    [mailComposeController setMessageBody:@"This is my new Wallpaper." isHTML:NO];
    UIImage *img=mainImageView.image;
    UIImage *img1=[UIImage imageNamed:@"aaa.jpg"];
    NSData *imageData = UIImagePNGRepresentation(img);      
    [mailComposeController addAttachmentData:imageData mimeType:@"image/jpg" fileName:[NSString stringWithFormat:@"photo.png"]];

    [self presentModalViewController:mailComposeController animated:YES];
    //[mailComposeController release];

}

它在 ios5 中工作正常，但在设备上的 ios6 m 测试中不工作

在 appdelegate 的 didfinishloading 中尝试以下代码

rootController = 
    [[firstViewController alloc] 
     initWithNibName:@"firstViewController" bundle:nil];
    navigationController = [[UINavigationController alloc]initWithRootViewController:rootController];
        window = [[UIWindow alloc] 
                  initWithFrame:[[UIScreen mainScreen] bounds]];
        [window addSubview:navigationController.view];
[window makeKeyAndVisible];

rootController 是一个 uiviewcontroller 实例
