make one tab of ios tabbar app portrait orientation only

Question

i have a tabbar ios app. i want to make one of the tabs portrait only. how do i do that? i already tried the solution in How to force view controller orientation in iOS 8? and didn't help. I put that in view controller's .m code. This view controller has both a UIView and UITableView in it. pl see image below;

thank you.

Answer 1

in your all viewcontroler write this code:

- (NSUInteger)supportedInterfaceOrientations
{
  return UIInterfaceOrientationMaskAll; //allow rotate landscape, portrait
}

and write this code in in which viewconroller you want only portrait.

- (NSUInteger)supportedInterfaceOrientations
{ 
  return UIInterfaceOrientationMaskPortrait|UIInterfaceOrientationMaskPortraitUpsideDown; // portrait only 
}

OR you can use this one:

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
    if ([self.window.rootViewController.presentedViewController isKindOfClass: [CompareViewController class]])
    {
        CompareViewController *compareController = (CompareViewController *) self.window.rootViewController.presentedViewController;

        if (compareController.isPresented)
            return UIInterfaceOrientationMaskLandscape;
        else return UIInterfaceOrientationMaskPortrait;
    }
    else return UIInterfaceOrientationMaskPortrait;
}
