Set the maximum zoom scale on a UIImageView?

Is there a way to set the maxim开发者_如何转开发um zoom level on a UIImageView?

I think imageviews don't really have the funcionality to zoom, most likely you'll want to slap down a uiscrollview and then insert the imageview as a subview, at that point you'll be able to set the max/min zoom scale on the scrollview. There is an apple sample code project called scrolling that is pretty simple example of scrollviews and imageviews:

hope that helps.
