calling optional delegate methods

Question

i created a delegate for a class

@protocol gameDelegate <NSObject>
@optional
-(void)gameStarted;
@required
@end

now in my game object i called this method:

[self.delegate gameStarted];

so now, if i initiate this object anywhere and set the delegate everything works fine until the gameStated gets called, because its not implemented in the main object where the game object is created (because its optional).

i tried some variations of this

if(![self.delegate respondsToSelector: @selector(gameStarted)]) {
    //[self.delegate gameStarted];
}

but this is not working for me. any ideas how to make this "really" optional?

thanks in advance

Omit the negation from your if statement:

if ([self.delegate respondsToSelector:@selector(gameStarted)]) {
    ...
}
