CCPinchGestureRecognizer

CCPinchGestureRecognizer is a subclass of CCGestureRecognizer that looks for pinching gestures involving two touches. When the user moves the two fingers toward each other, the conventional meaning is zoom-out; when the user moves the two fingers away from each other, the conventional meaning is zoom-in. Pinching is a continuous gesture, and thus the associated action method is called every time a finger moves enough to be considered a pinch gesture.

Example

CCPinchGestureRecognizer * pinch = CCPinchGestureRecognizer::create();
pinch->setTarget(this, callfuncO_selector(HelloWorld::didPinch));
pinch->setCancelsTouchesInView(true);
this->addChild(pinch);
