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.
