UIScrollView contentSize not working

Question

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

Answer 1

Setting the contentSize in viewDidAppear is critical.

But I also had a variation of what worked in the 3.5 inch screen, and the 4 inch screen. The 4 inch screen worked, the older one does not. Both iOS 7. Bizarre is an understatement!
