How to initialize view without known frame?

Question

I'm building view without .xib file, just using loadView method. But in the point, when loadView is called, the frame of view is yet unknown. So, I use it just to build view hierarchy without concrete frames. (Than I update view's layout when it's frame is known.) The question is: should I use [[UIView alloc] init] or [[UIView alloc] initWithFrame:CGRectZero] or may be something else, to initialize view without known frame? Here is the code:

- (void)loadView
{
    UIView *containerView = [[UIView alloc] init];
    // or 
    // UIView *containerView = [[UIView alloc] initWithFrame:CGRectZero];
    // or something else?        

    // ...

    self.view = containerView;
    [containerView release];
}

Answer 1

- (id)initWithFrame: is the designated initializer for UIView, so you should use that, with a zero-sized rect.
