The signature of this method is: - (CGSize)sizeThatFits:(CGSize)size I don't understand what the size parameter is used for. Apple's documentation states that it is "The current size of the receiver." But the receiver presumably knows its current size. So why does it need to be passed in? When I experimentally pass in other va...
I have a few UILabels in my view with their height set using sizeWithFont:. I set the autoreszingMask to flexible width and height, however on rotate the width changes (am assuming because self.view's width changes and its set with a width relative to self.view) but the height of it doesn't change to fit the content again. This results ...
I'm currently doing the tutorials from O'Reilly's 3D programming for the iPhone and have come across some difficulties, mainly one in particular.

In your knowledge, is there any practical way to do this? Side note: I looked at UIPasteboard and all that but it is NOT what I'm looking for as it does not offer a o...
