I'm developing an app that saves html files locally on iPhone file system, then load them in UIWebView. I want to be able to zoom or double tap programmatically on the UIWebView, I tried searching for javascript code, but I could only scroll.

I also tried the webview transform, but didn't work out for me. I found this method

sendAction:to:from:forEvent:

http://developer.apple.com/iphone/library/documentation/UIKit/Reference/UIApplication_Class/Reference/Reference.html#jumpTo_26

in the UIApplication class, that can send actions to controls.

Does anybody know how to send the double tap action programmatically to a UIWebView on a certain x,y?

get the UIWebview's subview which is a UIScrollview

UIScrollView *sview = [[webview subviews] objectAtIndex:0];

Then use zoom methods on that.
