I'm trying to use categories to separate two sections of one class. The code looks as follows:

[ MyClassExtension.h ]

#import <MyClass.h>
	This is plain wrong:
	Your own headers should be included with:
#import "MyClass.h"
	Angle brackets are for standard headers only.
@interface MyClass (MyClassExtension)
- (void) extraMethod;
...
@end

[ MyClassExtension.m ]

#import "MyClassExtension.h"
@implementation  MyClass (MyClassExtension)

- (void) extraMethod
{
...
}

@end

Now, do I have to include
#import "MyClassExtension.h"
in the file MyClass.h ? If I do so, I get the error 'cannot find interface section for MyClass'
If I don't, I get the compiler warning 'MyClass may not respond to extraMethod' if I try to call it from MyClass.


So, what is the solution for this?

Thanks for your time,

Arthur C.
