frame size does not change in landscape mode

cocoa-touch, iphone

Solution

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.

Problem

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?
