How do I initialize a view without a known frame?

I am creating a view without a file .xib

using the method loadView

. But at the point when loadView is called, the frame of view is not yet known. So I only use it to create a view hierarchy without specific frames. (Than I am updating the view layout when known). The question is, should I use, [[UIView alloc] init]

or [[UIView alloc] initWithFrame:CGRectZero]

or could there be something else, to initialize a view without a 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];
}
