is self referring to the actual class itself. And super is referring to the NSObject ?

confused between super and self. Also is there any documentation on self ?

I know this is an old question but I'm going to answer in case anyone else has this question. self is referring to the instance of the class. For example, say you initialize MusicLibrary *musicLibrary, then self refers to musicLibrary the instance of class MusicLibrary. As for super, if the super class of the class in question is NSObject then yes super refers to NSObject.
