How to load NSURL which contains hash fragment "#" with UIWebView?

Given a local URL address like index.html

Now I need to use UIWebView to load it in iPad. I followed these steps:

1. Create NSURL

   NSURL *url = [NSURL fileURLWithPath:@"http://mysite.com#page1"];
   

2. Load with UIWebView for local HTML/JS/CSS etc

   [webView loadRequest:[NSURLRequest requestWithURL:url]];
   

But it doesn't work, because "#" is converted to "%23", so the URL string is

http://mysite.com%23page1

My question is, how to fix this auto-conversion issue and let UIWebView access the URL which contains the hash fragment "#"?
