UIWebView 缓存页面的问题 [英] Issue with UIWebView caching pages

问题描述

我正在将一个远程 html 页面加载到 UIWebView 中，该页面使用我的 mac book pro 保存并通过 OS X 的内置 Apache 服务器提供.

I'm loading a remote html page into a UIWebView, the page is held on my mac book pro using and made available via OS X's built in Apache server.

我注意到，如果我在 UIWebView 中加载页面，然后对页面进行更改并重新加载，则更改不会反映出来，因此它可能被缓存在某处.即使我退出包含 UIWebView 的应用程序并重新启动它，我也会得到这种行为.

I've noticed that if I load the page in the UIWebView, then make changes to the page and reload it then the changes are not reflected, hence it must presumably be being cached somewhere. I get this behavior even if I quit the app containing the UIWebView and re-launch it.

网页缓存在哪里?是否可以强制 UIWebView 获取最新更新的页面?

Where is the web page being cached? Is it possible to force the UIWebView to get the latest updated page?

推荐答案

试试这个 -

[[NSURLCache sharedURLCache] removeCachedResponseForRequest:NSURLRequest];

这将删除特定请求的缓存响应.还有一个调用将删除在 UIWebView 上运行的所有请求的所有缓存响应:

This would remove a cached response for a specific request. There is also a call that will remove all cached responses for all requests ran on the UIWebView:

[[NSURLCache sharedURLCache] removeAllCachedResponses];
