You can use the webview delegate

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType

You can retrieve the URL of the request from the request parameter of the method. Check whether it matches the URL of play now button.
