Change the scale factor in UIScrollView

Question

Hi,

Is it possible to change the scaling factor of a UIScrollView? What I mean is I can only use two pinch gesture to completely zoom-out the content view to its minimum scale or two expand gesture to completely zoom-in the content view to its maximum value. Like for example, the minimum scale of the UIScrollView is 0.32 and just by two pinch gesture the content view will scaled to 0.32.

Thanks.

There's no property directly for that, but I bet you could make it work by implementing the UIScrollViewDelegate protocol and overriding the viewForZoomingInScrollView: method, then from that method manually alter the UIScrollView's zoomScale property.
