Three20 iOS 6 Rotation

Today, I was working on updating one of my apps for the iPhone 5 and after dealing with iOS 6. I realized my view controllers weren’t rotating. All that was required was simply adding this line after the TTNavigator had been setup.

[[[UIApplication sharedApplication] keyWindow] setRootViewController:[[TTNavigator navigator] rootViewController]];

This is due to the changes in the ViewController rotation API in iOS 6. A rootviewcontroller must be set for the main window of the application.

  All you need to do to handle individual view controller rotation is add the methods shouldAutorotate and supportedInterfaceOrientations.
  
  Both are in the new UIViewController documentation.

This doesn’t seem to work for me, please could you include your setup code for three20? eg when you first set up the TTNavigator, and call the first url? I have tried the above and shouldAutoRotate never gets called in the first view controller which three20 visits. If however I init the view controller myself and set window.rootViewController = myFirstViewController, shouldAutoRotate does get called! Very odd!

Thanks
