UIView's that don't handle their events pass them up the chain. By default, this passes them to their parent View, and if not handled (ultimately) to their parent UIViewController. UIScrollView breaks this (there's lots of questions on SO, variations on the theme of "why does my app stop working once I add a UIScrollView?) UISV decides...
I'm creating a comicbook-like application. I'm using a UIScrollView with paging enabled to display the hi-res full-screen images (the app works similar to Photos.app but with zooming disabled). The final product will have nearly 200 images that need to be paged through by the user. How do I go about setting up the UIScrollView for such a...

A normal configuration for starting up is something like this: CGRect cs2 = CGRectMake(0, 0, 4000, 4000); CGPoint screen = {[UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height}; self.canvas.frame = cs2; //canv...

I have already built a UIViewController subclass with a bunch of controls in it, and just realized that if I rotate the iPhone, half of the controls become invisible. So, I would like to somehow make the UIViewController's UIView scrollable so that when the device (or the Simulator) rotates, the user can scroll the view to see all the co...
