Get a problem:
I am having view controller A setup in xib with auto layout and being pushed via pushViewController from home view controller. Home view controller is embedded in a navigation controller.
I tried to use pushViewController, push view controller B, another instance of the same class as A,
but I found that, the viewDidAppear is called in B even before the viewWillLayoutSubviews and viewDidLayoutSubviews
So when I tried to get a sub view's frame in viewDidAppear, it is not correct. What's wrong?
Some trace:
