Change the scale factor in UIScrollView

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 UIS开发者_如何学编程crollView 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.
