In my app users login through a SafariWebViewController and I am trying to implement a logout button for my app. When the button is pressed the following code is called.
在我的应用程序中，用户通过SafariWebViewController登录，我正在尝试为我的应用程序实现注销按钮。按下按钮时，将调用以下代码。
NSHTTPCookieStorage *storage = [NSHTTPCookieStorage
sharedHTTPCookieStorage];
for (NSHTTPCookie *cookie in [storage cookies]) {
[storage deleteCookie:cookie];
}
[[NSUserDefaults standardUserDefaults] synchronize];
The code does not properly clear the cookies and when the user tries to login the SafariWebViewController remembers their last login. I am not sure what I am doing wrong that the cookies are not clearing. Any help would be appreciated.
代码无法正确清除cookie，当用户尝试登录时，SafariWebViewController会记住他们上次登录。我不确定饼干没有清除我做错了什么。任何帮助，将不胜感激。

NSHTTPCookieStorage only affects UIWebView and your own app's requests, it doesn't have any effect on WKWebView or SFSafariViewController, they use their own cookie handler.
NSHTTPCookieStorage仅影响UIWebView和您自己的应用程序的请求，它对WKWebView或SFSafariViewController没有任何影响，它们使用自己的cookie处理程序。
SFSafariViewController also shares cookies with the Safari app; my guess is only the user can clear the cache themselves (for obvious security/privacy reasons).
SFSafariViewController还与Safari应用程序共享cookie;我的猜测只是用户可以自己清除缓存（出于明显的安全/隐私原因）。
Use UIWebView or WKWebView if you want to control the cache.
如果要控制缓存，请使用UIWebView或WKWebView。
