删除cookie UIWebView

Question

如何删除UIWebView中的cookie？这段代码：

NSArray* cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];
for (NSHTTPCookie *cookie in cookies) {
 [cookies deleteCookie:cookie];
}

删除cookie但是当我重新启动我的应用程序时，NSHTTPCookieStorage中有相同的cookie。有时这段代码有效，但我想让它每次都有效。如何解决这个问题？

Answer 1

这对我有用：

NSHTTPCookieStorage* cookies = [NSHTTPCookieStorage sharedHTTPCookieStorage];

NSArray *allCookies = [cookies cookies];

for(NSHTTPCookie *cookie in allCookies) {
    if([[cookie domain] rangeOfString:@"facebook.com"].location != NSNotFound) {
        [cookies deleteCookie:cookie];
    }
}

Answer 2

尝试这样的事情：

NSHTTPCookieStorage* cookies = [NSHTTPCookieStorage sharedHTTPCookieStorage];
        NSArray* facebookCookies = [cookies cookiesForURL:
                                    [NSURL URLWithString:@"http://login.facebook.com"]];
        for (NSHTTPCookie* cookie in facebookCookies) {
            [cookies deleteCookie:cookie];
        }

Answer 3

删除单个cookie并不总是因某些奇怪的原因而起作用。要真正删除cookie，您需要存储非特定的cookie，然后重新加载它们，然后遍历所有cookie并删除它们，如此

NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];
   if (cookies != nil && cookies.count > 0) {
       for (NSHTTPCookie *cookie in cookies) {
           [[NSHTTPCookieStorage sharedHTTPCookieStorage] deleteCookie:cookie];
       }
       [[NSUserDefaults standardUserDefaults] synchronize];
   }

Answer 4

请务必致电：

[[NSUserDefaults standardUserDefaults] synchronize];

Answer 5

类似于前一个但更简单：

NSHTTPCookieStorage* cookies = [NSHTTPCookieStorage sharedHTTPCookieStorage];

NSArray *allCookies = [cookies cookies];

for(NSHTTPCookie *cookie in allCookies) {
    if([[cookie domain] contains:@"facebook.com"]) {
        [cookies deleteCookie:cookie];
    }
}

＆＃34;最佳答案＆＃34;很糟糕，因为它允许删除指定具体URL的cookie。例如，您删除了＆＃34; login.facebook.com＆＃34;的cookie。但你可能会错过＆＃34; www.login.facebook.com＆＃34;
