How to clear UIWebView cache?

I need UIWebView to display some local .webarchive file. But images there have same names, so UIWebView shows only one image all the time. How can I clear the cache?

Thanks in advance

// Flush all cached data
[[NSURLCache sharedURLCache] removeAllCachedResponses];

NSURLRequest* request = [NSURLRequest requestWithURL:fileURL cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:60.0];

[webView loadRequest:request];

(now with typo fixed)

I've had this issue myself with script and css files being cached.

My solution was to put a cache-busting parameter on the src url:

<script src='myurl?t=1234'> ...

where t=1234 changes each time the page is loaded.
