== Touch Notification Methods ==
Touch screen events cause one of four methods on the first responder object to be called. The method that gets called for a specific event will depend on the nature of the interaction. In order to handle events, therefore, it is important to ensure that the appropriate methods from those outlined below are implemented within your responder chain. These methods will be used in the worked example contained in the [[iOS 4
Phone Multitouch, Tap and Gesture Event Handling Tutorial]] and [[Detecting iOS 4 iPhone Touch Screen Gesture Motions]] chapters of this book:

== Summary ==
In order to fully appreciate the mechanisms for handling touch screen events within an iOS 4 iPhone application, it is first important to understand both the responder chain and the methods that are called on a responder depending on the type of interaction. We have covered these basics in this chapter. In the next chapter, entitled iOS 4
Phone Multitouch, Tap and Gesture Event Handling Tutorial we will use these concepts to create an example application that demonstrates touch screen event handling.
