Device orientation portrait only for one view controller

Question

I want only portrait orientation only in one view controller. I am doing this :

-(BOOL)shouldAutorotate{
    return NO;
}

-(NSInteger)supportedInterfaceOrientations:(UIWindow *)window{

    //    UIInterfaceOrientationMaskLandscape;
    //    24
    //
    //    UIInterfaceOrientationMaskLandscapeLeft;
    //    16
    //
    //    UIInterfaceOrientationMaskLandscapeRight;
    //    8
    //
    //    UIInterfaceOrientationMaskPortrait;
    //    2


    //    return UIInterfaceOrientationMaskLandscape;
    return 2;
}  

No success !!
I have tried many permutations and combinations as suggested on google but still not working.

Answer 1

您应该在shouldAutorotate返回YES，因为如果您的应用是横向的，在其他情况下您的视图将不会旋转回纵向。

Answer 2

You should try returning YES for shouldAutoRotate to make the below supportedInterfaceOrientations to become effect and also there is no method called -(NSInteger)supportedInterfaceOrientations:(UIWindow *)window on UIViewController instead use:

This code must go in your view controller which you want to be in portrait only.

-(BOOL)shouldAutorotate
{
    return YES;
}

-(NSInteger)supportedInterfaceOrientations
{
   return UIInterfaceOrientationMaskPortrait;
}
