IPhone auto rotation problem

Question

I am trying to create an app with multiple views. I have a seperate nib file and view controller for all the views. I have created methods in the app delegate that call up the different views as well as add a transition. I then call that method from the view controller subclasses. My problem is that I want the device to only support landscape mode in some views, and portrait in the others. I modified the -BOOL should autorotate to interface orientation, but, the only view that rotates correctly is the first view loaded. The subsequent ones launch in portrait mode and will only flip into landscape if the device is rotated into portrait then landscape, and sometimes I have to repeat this. Am I missing something here?

I guess I'll need to build a test bed to be of any more help. I still suspect this project would be easier for you if you changed your app's structure to use a single root view that remained over your window for the life of the program. In fact, the Utility template might be a good starting point for you. You might use the MainView for your splash screen, and the FlipsideView for your GameView, replacing the info button with whatever is calling exitSplash and removing or modifying the FlipsideView's Nav Bar depending on where you want to go from the GameView. Per my previous thread, using the Utility template with landscape views has its own set of problems, but at least the comments in my thread would then apply, and others could help you without building a test bed from scratch. In particular, you might want to try xnav's suggestion to start with the Tab Bar Application template which you'll find near the end of that thread.
One more snippet of code that might be useful to you:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
UIView *rotatingView = rotatingViewController.view;
return [rotatingView superview] != nil ? YES : interfaceOrientation == UIInterfaceOrientationPortrait
|| interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown;
I put the above in my RootViewController.m so that only one of its subviews would rotate into landscape orientation. To avoid using the undocumented setOrientation method of UIDevice, I then ensured that users could only switch away from the rotatingView when the device was in portrait. Of course if you choose to use setOrientation, that would offer you even more flexibility.
Best of luck on your app!!
