Cocos2d with UIPinchGestureRecognizer

Question

In Cocos2d while using the UIPinchGestureRecognizer, how do you get the pinch coordinates?

Answer 1

-(void)handlePinchFrom:(UIPinchGestureRecognizer*)recognizer
{
    // How to get the coordinates.
    CGPoint touchLocation = [recognizer locationInView:recognizer.view];
    touchLocation = [[CCDirector sharedDirector] convertToGL:touchLocation];
    touchLocation = [self convertToNodeSpace:touchLocation];

    // How to get the scale.
    float scale = recognizer.scale;
}

... assuming that self is your scene.
