objective c - UIScrollView contentSize not working

I put a UIScrollView in my nib's view, and linked it to a an IBOutlet property.

Now, when I do this in my viewDidLoad method, it seems to have no effect on the contentSize:

self.sv.backgroundColor = [UIColor yellowColor]; // this works
CGSize size =  CGSizeMake(1000.0, 1000.0); 
[self.sv setContentSize:size]; // this does not

It behaves as if the contentSize was the same as the frame. What's going on? This started working when I turned off AutoLayout. Why?

I had the same problem. Auto Layout for UIScrollView is messed up.

Work around: Put everything in the UIScrollView into another UIView, and put that UIView as the only child of the UIScrollView. Then you can use Auto Layout.

If things near the end is messed up (the end of whichever direction your UIScrollView scrolls), change the constraint at the end to have the lowest possible priority.
