receiver type *** for instance message is a forward declaration

Question

In my iOS5 app, I have NSObject States class, and trying to init it:

states = [states init];

here is init

Answer 1

That basically means that you need to import the .h file containing the declaration of States.

However, there is a lot of other stuff wrong with your code.

• You're -init'ing an object without +alloc'ing it. That won't work
• You're declaring an object as a non-pointer type, that won't work either
• You're not calling [super init] in -init.
• You've declared the class using @class in the header, but never imported the class.
