Iphone – frame size does not change in landscape mode

cocoa-touchiphone

I have a UINavigationController that can rotate to landscape mode and that it initializes a new UIViewController and pushes it on the stack. On the UIViewController's viewDidLoad I just print the self.view.frame.size.

If the UINavigationController is in Portrait mode, the View Controller will print {320, 460}. However, when the Navigation Controller is in Landscape, the frame size is exactly the same. (To clarify, in the second case the UIViewController is initialized while the phone is already in landscape mode.)

Shouldn't the frame size of the view be rotated? And if not how I can I find the correct frame size without hardcoding the numbers?

You can't rely on the frame in landscape mode; you have to use a combination of bounds and center; frame is generated using a combination of those, and when there's a non-identity transform applied (as there is in landscape), it gets a little weird.

Objective-c – documented way to set the iPhone orientation

This is long after the fact, but just in case anybody comes along who isn't using a navigation controller and/or doesn't wish to use undocumented methods:

UIViewController *c = [[UIViewController alloc]init];
[self presentModalViewController:c animated:NO];
[self dismissModalViewControllerAnimated:NO];
[c release];

It is sufficient to present and dismiss a vanilla view controller.

Obviously you'll still need to confirm or deny the orientation in your override of shouldAutorotateToInterfaceOrientation. But this will cause shouldAutorotate... to be called again by the system.
