-(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.

There's also some gesture code in CMMSimpleFramework. A bit hard to separate - but overall nice work. https://github.com/kimbobv22/CMMSimpleFramework
