View of frame not appeared to have set in awakeFromNib

I am using autolayout in my view controller, to align a uiview as if it were a navigation bar (aligned to top, stretched to trailing and leading sides and 44 height).

I have subclassed this view, and during awakeFromNib I want to add subviews to it.

However, when I adding these subviews (also with constraints to the parent view) it doesn't work.

Initially I thought the constraints were programmed incorrectly, however, after logging the frame of the view like so:

- (void)awakeFromNib
{
    [super awakeFromNib];

    NSLog(@"%@", NSStringFromCGRect(self.frame));
}

I get the following output:

2012-11-27 03:25:25.976 myApp[8262:c07] {{0, 0}, {0, 0}}

Yet when I log in, for example, touchesBegan:withEvent: it logs the correct frame size.

Does anyone know what might be causing this?

I have also tried setting setTranslatesAutoresizingMaskIntoConstraints:NO on all views involved. But nothing seems to work.

Thanks in advance!

When awakeFromNib is called, the view is not yet created. The best way to get properties of any kind from the view in this method is to call [self view] before trying to access properties.
