Simply by implementing the standard touch event methods the motion of a gesture can easily be tracked by an iPad application. Much of an iPad’s user’s interaction with applications, however, involves some very specific gesture types such as swipes and pinches. To write code to correlate finger movement on the screen with a specific gesture type would be extremely complex. Fortunately, iOS 4 makes this task easy with the introduction of gesture recognizers. In the next chapter, entitled [[Identifying iPad Gestures using iOS 4 Gesture Recognizers (Xcode 4)|Identifying iPad Gestures using iOS 4 Gesture Recognizers]], we will look at this concept in more detail.
