How to get real size UIView with autolayout
Before your "getting real size code", insert the following code:
[view setNeedsLayout];[view layoutIfNeeded];
Since everybody assumes the access is done via a UIViewController and not inside a UIView subclass, the answers don't prove really useful. The correct way to get the correct size of a UIView subclass is in layoutSubviews.
The simplest solution is to just run that code in -viewDidAppear: (after autolayout has been run).
