UIWebView 清除缓存

//清除cookies

NSHTTPCookie *cookie;

NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];

for (cookie in [storage cookies])

{

[storage deleteCookie:cookie];

}

//    清除webView的缓存

[[NSURLCache sharedURLCache] removeAllCachedResponses];

一般这样就能删除UIWebView 中的缓存。
