== Subclassing ==
<googlehtmlet>ADSDAQBOX_FLOWadsdaqbox_flow</googlehtmlet>
Subclassing is an important feature of any object-oriented programming environment and the iOS SDK is no exception to this rule. Subclassing allows us to create a new class by deriving from an existing class and then extending the functionality. In so doing we get all the functionality of the parent class combined with the ability to extend the new class with additional methods and properties.
