Abstract classes

I'm converting a C++ class hierarchy to Objective-C, now I wonder, what are the dos and don'ts of abstract classes in Objective-C?

Should an abstract class have an init method or shouldn't it have?
Is there a notation to indicate what methods should be implemented by subclasses, like in C++?
If I implement a initWithCoder in the subclasses, how should this method be written in the abstract super class?
