Finding subclasses of a class in objective-c

Question

In the Apple docs there are a lot of classes that are meant to be subclassed or abstract classes. How can i find which classes are subclass of a given class?

For instance: If i'm looking at UIDummyClassAbstract, how can i find all classes that are subclassing UIDummyClassAbstract?

It would help to get a better overview

Answer 1

It is not exactly in Documentation but you can inspect class hierarchy this way:

1. Open "Symbol Navigator" (look for icon)
2. Toggle "Show only project defined symbols" option off ( icon in the bottom at the window)
3. You can inspect class tree now :)
