I have a webpage loaded in a UIWebView, and a javascript function of the page needs to data from native iOs app, a NSString. How can a Js function access the data in native app?
Thanks,

You can execute JavaScript in your UIWebView from Obj-C. Simply call [webView stringByEvaluatingJavaScriptFromString:@myJavaScript];.
I could imagine a setup like this:
Webpage
<html>
<head>
<script type=text/javascript>
function callmeFromObjC(para1) {
// do something
alert(para1);
}
</script>
</head>
<body>
</body>
</html>
Objective-C
NSString *myParameter = @myParameter;
[webView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@callmeFromObjC('%@'), myParameter]];
