在通用应用程序中固定Iphone的方向

Question

我已经开发了一个通用应用程序,我想支持IPAD的所有方向,但对于Iphone,我只想要UIInterfaceOrientationPortrait和UIInterfaceOrientationPortraitUpsideDown,我只有这个

-(BOOL)shouldAutorotate {
    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone){
        return NO;
    }else{
        return YES;
    }
}
- (NSUInteger)supportedInterfaceOrientations{

     if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone){
         return UIInterfaceOrientationMaskPortrait;
     }else{
        return UIInterfaceOrientationMaskAll;
     }

} 
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
     if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone){

    return interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown ;
     }else{
         return YES;
     }

}

但仍然没有停止在景观中的方向
