I\'ve got an app that was working perfectly on iOS 6, but on iOS 7, if there is a very specific action taken by the user (too complex to get into but it uses a UIWebView>
if you are using IOS i Wouldn't use onClick. IOS takes your on click and puts some funky 200 ms delay on onClicks which results in sometimes breaking the "webglue". JavaScript has a full touch library that I would use and also something like Hammer.js will resolve your problem. also, i would use phonegap for the webview component of your app (even if it is not the full app) because they fix alot of quirks/bugs IOS has with their native webview (even if it is just for website browsing).
