在故事板中，嵌入式视图控制器不再与其容器视图大小相同

Question

I have a storyboard with multiple view controllers, several of which have container views with embedded view controllers. Until recently, the embedded view controllers correctly sized themselves in the storyboard based on the size of their container views. But now they all show at 600 x 600 (which is not the size of any of the containers). They do assume the proper sizes when I run the app.

Is there a way to restore the default behavior in the storyboard? (And what might have caused this?) (XCode 7.2)

Answer 1

In the Simulated Metrics section of the size inspector change the Size from Inferred to Detail :

Answer 2

Change the ViewController/Navigation Controller attribute in 'Simulated Metrics' from Inferred to 'Page Sheet' or 'Form Sheet' to get a full size storyboard. This removes the shrinking effect
