MPMoviePlayerViewController doesn't auto-rotate

Question

I'm having some strange behavior where my `MPMoviePlayerViewController` isn't `auto`-rotating when the `orientation` changes. However, I recreated the same view hierarchy in a fresh project and when the `MPMoviePlayerViewController` player was up, it rotated to every orientation. I've scoured the project looking for anything that might be setting the orientation explicitly, but there is nothing. I'll lay out all the relevant information here and the things that I've tried so far. The view hierarchy currently looks like this: - Navigation Controller - "Root" View Controller <- navigation controller's 'rootViewController' - "Feed" View Controller <- Pushed on the navigation stack by the Root VC - "Preview" View Controller <- Presented as a modal VC from the Feed - MPMoviePlayerViewController Subclass <- presented by the Feed VC via 'presentMoviePlayerViewControllerAnimated' Every class in the view hierarchy responds to shouldAutorotateToInterfaceOrientation with YES only for UIInterface…

Accepted Answer

Solution:

For anyone that might encounter this, the reason the video wasn't rotating was that I was accidentally adding the RootViewController has the window's rootViewController, rather than the UINavigationController.

```
self.window.rootViewController = navController; 
```

is correct

`self.window.rootViewController = rootViewController; `

is not

Thank you guys for your help and input along the way.
