Gettin my app to autorotate

Question

My app got rejected for not autorotating so I am trying to implement that now.
My app is a painting application based off GLPaint. The problem with this is that there is no ViewController class and that is where this code is found that does the autorotation:
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceO rientation {
// Return YES for supported orientations
return YES;
So since I dont have this class only a AppController and PaintingView, where do I implement this code. Is it possible to create a view controller and have it link up to control my MainWindow.xib?
If not, then how can I make my app autorotate. Thank you.

OK. I am assuming that you are using the OpenGLES Template iPad application to start your project. Why Apple choose to make it look like it does is beyond me, but there you go.
What you need to do is start a View based application, and then copy in the opengl parts of the opengles template project into the view based project. Then in the ViewDidLoad function, you need to create an instance of your OpenGLES View (EAGLView or something like that). You then have an autorotating OpenGLES project. Yay.
There are other issues with doing this, but with a simple project it should be fine. If, like me, you want to run the OpenGL updates in a thread, it then becomes a world of pain, with everything being initialised at the wrong times and crashing in openGL functions etc.... but for what you are doing, this will work perfectly !
Haven't got the code to hand at the moment, but if you look on the web, there should be examples like this.
