Hi, Can you guys give some hints about the UNDOCUMENTED APIs to have the checkerboard pattern for uiwebview. For the pages with large contents , zooming and scrolling is not smooth.

I know that private APIs can do it . Any help please?

Thanks in Advance.

Apple has some iPhone specific META tags that can disable the zoom.

Add:

into your HEAD section of your HTML, et voila, no more user zooming.

I think it’s better call Objective-C methods with window.open(“”) rather than document.location = “” . Than you can continue precess your javascript;

Your override of hitTest has helped me so much. I was trying to figure out how to detect clicks using a dummy class and all sorts of hassle, but your just made it extremely easy for what I needed to detect the click for. Thank you very much!

Is there a way one can auto-scroll UIWebView? I know of “window.location.hash” but I am looking for a “smooth” scroll and not the “jump” the previous code does. Any thoughts?

[...] 7 tips for using UIWebView | Coding Ventures For an IPhone app I have been building, I decided to use the UIWebView to render SVG files, instead of doing the vector rendering myself. I needed to have a way to read-in files generated from a vector authoring tool (Illustrator etc.) and after initially looking for an open-source SVG parsing/rendering engine of some sort, I decided on hosting the UIWebView itself instead and use the SVG rendering capability of WebKit.

You have 3 snippets for the JavaScript calls Objective-C section. The second two make sense to me, but I don't know exactly what this line indicates:

myapp:myfunction:myparam1:myparam2

I can see it is referring to a function and params, but I don't know how to use it.

Is this a protocol in Objective-C? I don't recognize the format.

Making a connection between JavaScript and Objective-C is a key capability for us. It would be great to get some more information about how this works. I have played with Phonegap, but have run into problems with that framework... and in any case I would prefer to have more control, if I can.

Thanks for a great post.
