Block the pinch in a scrollview

microfott · 11-17-2010, 10:03 AM

Hi everybody, I need to block the pinch gesture of an image in a scrollview when the user reach the max or min value of scale.

I mean: when the user starts to pinch, the image starts zooming but when the max/min value of scale is reached, the zoom must stop also if the user's fingers are still moving..

Any suggestion how to do it?
I already set the max/min value of the scale (if too big/low) in scrollViewDidEndZooming.

I hope you understand my question.

If I'm correctly understanding what you're describing, you can prevent this by setting the scroll view's bouncesZoom property to NO. That should stop the zooming immediately when the user hits one of the scale limits, instead of the default behavior of going beyond the limit and then "bouncing" back to the limit when the user lets go.

OMG .. I forgot to write "I'm a newbie" but you understood it by yourself... many thanks Chris, it's what I was searching for.
