How to call CCButton on parent view from the child view - ios

Question

In parent view, there's a CCButton called pausebutton, when click it, a child view will be added to this view
[[CCDirector sharedDirector] pause];
pausebutton.selected = YES;
pauseLayer *pauseLayer = [pauseLayer node];
[self addChild:pauseLayer];
in child view pauseLayer, also has a ccbutton called resumebutton, when click it, this child view will be removed from parent view, and both set the pausebutton's selected is NO.
- (void)backResume:(id)sender
{
[self.parent removeChild:self cleanup:YES];
[[CCDirector sharedDirector] resume];
}
but i can't find a way to call the pausebutton from child view, so can you help me?

Answer 1

On the parent class, add a method to force a pause :
in .h :
-(void) forcePause;
in .m :
-(void) onButton:(id) sender {
[self forcePause];
}
-(void) forcePause {
[[CCDirector sharedDirector] pause];
pauseLayer *pauseLayer = [pauseLayer node];
[self addChild:pauseLayer];
}
and in the child, when the condition to trigger a pause is met
[self.parent forcePause];
just the general idea, there are other ways to make this happen. This example would be for a very simple use-case/game. Alternately, in the parent you could be listening for a #"forcePause" notification and notify in the child.
