// Get pinch scale into pinchScale

float scale = fmaxf(pinchScale,
    fminf(ipadWidth / imageWidth, ipadHeight / imageHeight));

// Use scale instead of pinchScale

I Think it is better to take imageview into scrollview, By default scrollview has Zooming in - Zooming out options with implementing its delegate methods....not a problem also take pinch gesture it is also good one , you can fallow fallowing links ,they are helpful i think so...

using pinch gesture recognizer you can use these links for your requirement...
