Question

(IPhone newbie question)

I’ve subclassed a UIViewController and a UIView, and created a InitWithFrame for the view. My custom controller uses this to initialize its view, by frame, in its loadView function.

I plan to use the controller and view in my code at different places. At times under a navigation controller, toolbar, both, neither etc. This means that the code creating the view in loadView of the controller, should ideally know in what size to create the view.

How do I avoid hard coding these sizes for the different cases? Is there a way to build the surrounding controllers (navigation bar, etc.), then figure out the size of the viewable frame, and somehow only then create my controller and initialize my custom view using this frame size?

If my design is incorrect, any tip could be of great assistance… Thanks!

Answer 1

For the initial vew size you might be interested in [UIScreen applicationFrame]. Returned rectangle accounts for the status bar and interface orientation. When your controller is used inside a navigation controller or other wrapper that changes the available screen space, I think the view gets resized automatically (through UIViewController magic), so there’s nothing you have to do (apart from setting a permissive autoresizingMask).
