I have to display an .html file which needs highcharts.js, jquery.min.js in order to display a graph. I am planning to display the .html file in a UIWebView.
You can boot http server locally (via for example https://github.com/robbiehanson/CocoaHTTPServer) and set //Documents/yourFolder as server root.
Then you can open in UIWebViewNSURL like this: http://localhost:8080/index.html
