How to access javascript function variable in UIWebview

Question

I want to print variable value of javascript function in xcode console. This is the script

<script language="javascript" type="text/javascript">
function myFunction() {
var abc =@"My Value";
      alert('Hello world');
}
</script>

With help of

[webView stringByEvaluatingJavaScriptFromString:@"myFunction()"]];

I able to run function and alert of @"Hello world" is display.

My main concern is NSLog(@"abc Value %@",?); How to access abc value ="My Value";

I am new in javascript and don't have much knowledge of basic of javascript.

waiting for replay'

Thanks

And if you require this abc value to your objective c code then return abc from javascript function. And in objective c, assign to some string variable. — Mrunal, Aug 08 '13 at 13:10
