iOS Question

UIView created in IB has no frame in viewDidLoad and awakeFromNib

I'm sorry if I missed something here, but I thought UIView objects that were created in IB should have their frames created in viewDidLoad so you can do initial setup based off of this view in viewDidLoad or awakeFromNib or viewWillAppear. I logged the output in each method:

NSLog(@"%@ %s", NSStringFromCGRect(self.zoomView.frame), __FUNCTION__);

And in all I get {0, 0, 0, 0}.

This is the first nib in my UIStoryboard, and I'm using Autolayout and iOS 6. I could have sworn on previous apps I have used the frame of other UIView objects created in IB to set things up. Is there something that has changed? Or do I just remember it incorrectly? Thanks!


I had the exact same issue. Yes, you remember correctly - it used to be different in iOS 5. I always set up my views in viewDidLoad: and the frame was already the way it was going to be when the view was actually on screen.

Now in iOS 6, you'll need to put your code into viewDidAppear: to have a valid frame to work with, if auto layout is enabled. Apparently the laying-out is done in between those two calls.
