from ibaction i need to call this function or webview delegate – user1662494 Dec 27 '12 at 05:43
If you wanna call the JS method on click of the button,you need to put this logic in the IBAction. If you wanna call the JS method while loading page into UIWebView,put this logic in delegate method webViewDidStartLoad .. – Murali Dec 27 '12 at 05:55
can you send me some sample code for that – user1662494 Dec 27 '12 at 05:57
