I want a 2-page horizontally scrolling UIScrollView on a simple UIViewController. Very similar to what Twitter does to swipe between Home, Discover and Activity views.
Using storyboards, dropping a UIScrollView on a UIViewController is a piece of cake. Pinning the UIScrollView to the top and bottom layout guides - left and right parent view edges, piece of cake. I can paint the background bright green and see it just fine. What is the best way to layout the 'content' views? I want them to be the size of the UIScrollView's frame. Specifically, what is the best way to do this using AutoLayout? I know that Autolayout will cause the UIScrollView's contentSize to adjust to fit its child views ... so does that mean I need to create height and width constraints on the child views - ie: I need actual numerical values? If so, I clearly don't want to hard-code 320.0 as the width ... so is it appropriate to CGRectGetWidth(scrollView.frame) or CGRectGetHeight(scrollView.frame) and rely on "frame" or "bounds" values of the parent to setup the autolayout stuff in the children? Clearly this can only be done after the scrollView has loaded and positioned itself. It feels weird to mix the two abstractions and have to wait until the scrollview is positioned before creating the constraints on the children - feels dangerous/brittle. Feels like I'll have to manually handle device rotations, etc ???
