When my application starts the viewDidLoad method, it runs a snippet of code that accesses an X site, retrieves an HTML form and displays it in a UIWebView.
My problem is this, when a link is clicked I need to intercept the return HTML to perform another treatment, however, I do not know how to detect that the webview was updated with a new request, or even get the html present.
HTML ...
<html>
<body>
<input id="myId" type="hidden" value="TextValue"/>
</body>
</html>
No Swift ...
var id:String = IBwebView.stringByEvaluatingJavaScriptFromString("document.getElementById('myId').value")!
println(id)
in the Obj c:
NSString* value = [webView stringByEvaluatingJavaScriptFromString:@"document.getElementById('myId').value"];
You must implement the UIWebViewDelegate protocol, and perform the action you need in the viewDidFinishLoad method.
