macOS Virtual interface

[ncohen]

Hello,
I would like to create an interface without implementation... it would be an interface of a class which makes reference to the methods only. Is it possible to do that?

For example:

Superclass.h

@interface Superclass : NSObject
{
	
}
-(void)method1;
-(void)method2;
@end

Subclass.h

@interface Subclass : Superclass
{
	int variable1;
        int variable2;
}
-(void)method1;
-(void)method2;
@end

Subclass.m

@implementation Subclass
-(void)method1
{
      // some code
}

-(void)method2
{
      // some code
}
@end

This code doesn't work... is it possible to do something like that?

Thanks
