Objective-C: Importing headers in .h or .m?

Question

I\'m new to objective-c and would like to know the best practice for importing some external headers that I use in my class.

Should I be storing the #import \"classB.h\"

Answer 1

It is proper practice to put a forward class declaration (@class classB;) in the header and #import "classB.h in the .m

A forward class declaration, like @class classB; lets the compiler know it should expect the class later on, and it shouldn't complain about it at the moment.
