Javascript to Obj-c Injection (iphone)

To control in UIwebview  via javascript  Injection

Here we are overriding window.open method so that we can launch  this on separate browser rather than opening in webview .

- (void)webViewDidFinishLoad:(UIWebView *)myWebView {
    [self.webView stringByEvaluatingJavaScriptFromString:@"var script = document.createElement('script');"
     "script.type = 'text/javascript';"
    
     "script.text = \"var open_=window.open ;window.open=function (url ,name)  { var prefix='ns://'; "
     "open_(prefix+url);return (prefix+url)"
     "}\";"
     "document.getElementsByTagName('head')[0].appendChild(script);"];
  
    [UIApplication sharedApplication].networkActivityIndicatorVisible = NO;
      
   
}



 And then handle the special case in

-(BOOL) webView:(UIWebView *)inWeb shouldStartLoadWithRequest:(NSURLRequest *)inRequest navigationType:(UIWebViewNavigationType)inType {
   
   
    if ([[[inRequest URL] scheme] isEqualToString:@"ns"] == YES)
    {
        [self.webView stopLoading];
               NSLog(@"it works do what ever you want ");
      
}
}
