DESCRIPTION:

A series of examples that illustrate how to use UIScrollView.

1_TapToZoom demonstrates:
* Fitting the image to the screen on launch
* Detecting single, double, and two-finger taps using UIGestureRecognizer
* Zooming in response to taps

2_Autoscroll adds a thumbnail scroll view, and demonstrates:
* Use of the canCancelContentTouches property to track moving touches in a subview of a scroll view
* How to implement autoscrolling in response to a subview being dragged

3_Tiling demonstrates:
* How to subclass UIScrollView to add content tiling
* Reusing tiles to optimize performance and memory use
* Changing the resolution of the content in response to zooming
