This chapter introduces direct manipulation interfaces that go far beyond prebuilt controls. You see how to create views that users can drag around the screen. You also discover how to distinguish and interpret gestures, which are a high-level touch abstraction, and gesture recognizer classes, which automatically detect common interaction styles like taps, swipes, and drags.
