@class "className" VS #import "className.h"

In one of the diary app header files we used @class THDairyEntry instead of #import "THDairyEntry.h". What is the difference between this to methods?

In my understanding: (don't listen to me i'm a newbie) you use @class so you can save time. You use @class in your .h file, so you're telling: compiler, here comes a class and treat it that way. And #import do you use in the .m file. Because you don't have to 'use' the object in the header file (like running methods on it). You're only importing the whole file, in the file where you're using the object.

I'm little bit confused, as far as I know we import header files to be able to create an new object from the same king of the header file. I'm not really sure why we use @class "className"
