i think you should be able to manipulate the viewport using the safari meta tags

For example, to set the viewport width to the width of the device, add this to your HTML file:

<meta name = "viewport" content = "width = device-width">

To set the initial scale to 1.0, add this to your HTML file:

<meta name = "viewport" content = "initial-scale = 1.0">

To set the initial scale and to turn off user scaling, add this to your HTML file:

<meta name = "viewport" content = "initial-scale = 2.3, user-scalable = no">

Ya correct. But how to control it after the view is displayed and zoomed by the user ? – thndrkiss Aug 07 '10 at 17:22
The documentation states that by setting user-scalable to "no" will prevent the user from zooming at all? Maybe I am not understanding the question? – Aaron Saunders Aug 07 '10 at 17:35

It's not directly supported, but this thread has a workaround/solution.

If you want to reset the user scale to 1.0, at least on iOS 4.2 you can toggle scalesPageToFit:

webView.scalesPageToFit = NO;
webView.scalesPageToFit = YES;
