title: Limit maximum scale for scaling image with pinch gesture in IOS
body: <p>I am currently able to make an image scale by using the pinch gesture recognizer provided by Apple, but how can I limit the maximum scale for the image?</p>
  
  <p>I have been using the  <a href="http://developer.apple.com/library/ios/#samplecode/SimpleGestureRecognizers/Introduction/Intro.html#//apple_ref/doc/uid/DTS40009460" rel="noreferrer">SimpleGestureRecognizers sample</a> from Apple, which sets the scale to 1, and makes it very easy to scale image, but when I remove it, it jumps suddenly, which is not nice. But then it is hard to track the scale since its alway set to 1.</p>
  
  <p>Thank you in advance.</p>
