ios - UIScrollView's origin changes after popping back to the UIViewController

Question

I have a UIViewController subclass as a scene in the storyboard that contains a UIScrollView containing various subviews. One of the subviews is a UIButton which segues into another scene UIViewController subclass. When I come back from the view (pop the UIViewController off the navigation controller stack), I find that the scroll view's origin has somehow changed, although the contentsize and contentoffset seem correct.

What's also interesting is that the app has a tab bar, and when I tab away and back to that view, the scroll view is set back correctly with offset at (0, 0).

There is basically no code involved in this process, as it's pretty much all in the storyboard. As I am fairly new to using the storyboard, I figure I'm doing something wrong, although I don't know what. Any ideas as to what that may be? Perhaps sizing issues or constraints?

In iOS 7/8/9 simple self.automaticallyAdjustsScrollViewInsets = NO; solved the problem in my case.
