I don't see this in a quick test I just typed into Xcode. I did this in the .h
file
@interface RKControl : NSControl
@property SEL action;
@property (weak) id target;
@end
and .m
#import "RKControl.h"
@implementation RKControl
{
SEL myAction;
id __weak myTarget;
}
@synthesize action=myAction;
@synthesize target=myTarget;
@end
and I get no warnings or errors and the properties I believe match the
originals. I dropped one on a project as an NSView, set the class, connected up
a random target/action and debugged viewDidLoad to check the control was there
and had a correct target/action.
What are you seeing which is different? If you are having a problem then does
it work if you don't use synthesize and go back to the good old -(thing)value,
-(void)setValue:(thing)value?
