iOS6: supportedInterfaceOrientations not working (is invoked but the interface still rotates)

In my app I have multiple views, some views need to support both portrait and landscape, while other views need to support portrait only. Thus, in the project summary, I have all selected all orientations.

The below code worked to disable landscape mode on a given view controller prior to iOS 6:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
// Return YES for supported orientations
return (interfaceOrientation == UIInterfaceOrientationPortrait);

Since shouldAutorotateToInterfaceOrientation was deprecated in iOS6 I've replaced the above with:

return UIInterfaceOrientationMask.Portrait;

This method is correctly called when the view appears (I can set a breakpoint to ensure this), but the interface still rotates to landscape mode regardless of the fact that I'm returning the mask for portrait modes only. What am I doing wrong?

It seems that it's currently impossible to build an app that has different orientation requirements per view. It seems to only adhere to the orientations specified in the project summary.


If your are using a UINavigationController as the root window controller, it will be its shouldAutorotate & supportedInterfaceOrientations which would be called.

Idem if you are using a UITabBarController, and so on.

So the thing to do is to subclass your navigation/tabbar controller and override its shouldAutorotate & supportedInterfaceOrientations methods.
