UIScrollview Autolayout Issue

Question

I have a problem with autolayout(maybe) and my scrollview!

My Problem

1. I scroll down

Answer 1

The following code snippet in the containing view controller also seems to solve the problem, without relying on explicit sizes:

- (void)viewDidDisappear:(BOOL)animated {
  [super viewDidDisappear:animated];
  self.mainScrollView.contentOffset = CGPointZero;
}

It does reset the content offset to the origin, but it seems that so do the other answers.
