通用应用程序中Iphone的固定方向

Question

我已经开发了一个通用的应用程序，我想支持IPAD的所有定向，但对于Iphone我只想要UiInterfaceOrientationPrafficial和UiInterfaceOrientationPrafficiTupsidedown只有这一点，我有

-(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;
     }

}

但仍未停止景观中的定位

只需从概要中禁用除UIIterfaceOrientationPrazilit和UIIterfaceOrientationPrazilitUpsidedown以外的所有其他定向，如下面的描述所示。在图片中，颠倒是禁用的，请启用它。多谢了。
