iOS: How To Access Local File Using NSURL

ios_file_via_url.m

Use [[NSBundle mainBundle] resourceURL] to gain a URL string of your local resource.

For example you have index.html in you bundle resource directory. To create an NSURL of that local html file to display on your UIWebView. Simply do this.

NSString *resourceURLString = [[NSBundle mainBundle] resourceURL];

resourceURLString will return something like this: file:/../AppName.app/

NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@index.html",resourceURLString]];

Your URL string would look something like this: file:/../AppName.app/Index.html 

You can then load that local html file to your UIWebView.

NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webView loadRequest:request];

NOTE: If you want to use path to access local files. You can use this one below.

NSString *urlAddress = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html"]; //you can also use PDF files

NSURL *url = [NSURL fileURLWithPath:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webView loadRequest:requestObj];
