如何在cocos2d中使用MFMailComposeViewController以横向模式显示mail composer?

所以,当我在场景中触摸到一个CcLabel时,邮件页就打开了。

@interface EmailScene : CCScene <MFMailComposeViewControllerDelegate>
{
    MFMailComposeViewController *picker;
}

-(void)displayComposerSheet;

@end

@implementation EmailScene

- (id) init {

    self = [super init];
    if (self != nil) {
        [self displayComposerSheet];
    }
    return self;
}
-(void)displayComposerSheet
{

    [[CCDirector sharedDirector] pause];
    picker = [[MFMailComposeViewController alloc] init];
    picker.mailComposeDelegate = self;

    NSArray *toRecipients = [NSArray arrayWithObject:@"srikanth.rongali786@gmail.com"]; 
[picker setToRecipients:toRecipients];

    [[[CCDirector sharedDirector] openGLView] addSubview:picker.view];
    [[CCDirector sharedDirector] stopAnimation];
}
- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error
{
    [[CCDirector sharedDirector] resume];
    CCScene *Scene = [CCScene node];
    CCLayer *Layer = [GameWinScreen node];
    [Scene addChild:Layer];

    [picker.view removeFromSuperview];
    [[CCDirector sharedDirector] startAnimation];
    [picker dismissModalViewControllerAnimated:YES];
    [[CCDirector sharedDirector] replaceScene:Scene];
}

@end

但是,问题是我的游戏是在横向模式。所以,我需要邮件页以横向模式显示。但是,这里的邮件页是以纵向模式显示的。键盘以横向模式出现。但是,邮件镇定表处于纵向模式。

我们如何将“从我的iPhone发送”改为“从我的iPad发送”

非常感谢。
