Remove UIWebView's internal cache

Question

I\'m showing a web app in an UIWebView, and sometimes the content of pages will change. After content have been changed the app clears the cache. But when I go

Answer 1

It appears that what's happening here is that it reloads the actual HTML file, but does not necessarily reload the resources within that page.

A possible solution I've seen is to append a query parameter on to the end of the URL. For example:

NSString *testURL = [NSString stringWithFormat:@"%@?t=%@", url, randQuery];
[self.webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:testURL] cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:10.0]];

where you generate a random alphanumeric string as your randQuery query parameter, or keep a persistent count and just count up.

This should force the UIWebView to load from the remote resource.

I had the same issue and setting HTTPShouldHandleCookies property to NO fixed my problem.

For example:

NSMutableURLRequest  *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:strurl]];

[request setHTTPShouldHandleCookies:NO];

[webView loadRequest: request];

Hope this help.
