jQueryUI Drag & Drop compatibility w/ iOS

I have a web-based tool that utilizes jQuery 开发者_JAVA百科UI for drag'n'drop functionality. It works fine across all browsers however, webkit used in iPad and iPhone (and other touch screen smart phones) does not support that functionality. What is the best way to make it compatible with such devices?

Shall I add a script to check for device and if iDevice use different JS library? Or are there any scripts that make jQuery compatible?

Thanks.

I have not used it myself, but I understand that's the idea behind http://jqtouch.com/
