Error: Accessing unknown getter method?

Thanks…

#import <Foundation/Foundation.h>


@interface puppy : NSObject {
    int mack;
    int jack;
}
-(puppy *) waldo: (puppy *) f;
-(void) setMack: (int) m;
-(void) setJack: (int) j;
@end

#import "puppy.h"


@implementation puppy
-(void) setJack: (int) j{
    jack = j;
}

-(void) setMack: (int) m{
    mack = m;
}



-(puppy*) waldo: (puppy *) f{   

    return (f.jack + f.mack); // Error: <-- Accessing unknown "jack" getter method
                              // Error: <-- Accessing unknown "mack" getter method
}

You haven’t implemented the methods jack and mack.

- (int) jack { return jack; }
- (int) mack { return mack; }

But I’d recommend just using @property and @synthesize with no ivar.
