There is no way to always restrict a UIViewController to one orientation

Status:Duplicate/5855845 Resolved:
Product:iPhone SDK Product Version:2.2
Classification:Serious Bug Reproducible:Always
 
Summary:

When a UIViewController is part of a UINavigationController, the behavior defined in 

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation

is ignored.

Steps to reproduce:

- Create UIViewController and have shouldAutorotateToInterfaceOrientation only return YES for portrait mode.
- Create a second UIViewController and have shouldAutorotateToInterfaceOrientation always return YES
- Use a UINavigationController to push the second view controller onto the navigation stack
- Rotate the device
- Use the UINavigationController's back button to go back to pop the second controller off the stack.

Expected Results:

Since the first view controller says it doesn't support landscape mode, it should not be rotated.

Actual Results:

shouldAutorotateToInterfaceOrientation is ignored, and the view is rotated anyway.

I have the same (frustrating) issue, and I've logged a radar (6409481).

I'm implementing support for landscape orientation through and through. It isn't too hard, but I'm noticing that performance is lacking.

Thanks for your complete bug report. I am in the very same case.

Ran into this myself. Definitely sounds like a bug to me.

My workaround - disable the "back" button while the device is in landscape mode. Total hack, but gets around the problem for now.
