ios - 如何使用 sharedHTTPCookieStorage 删除 cookie 数据和用户默认值？

Question

我在 APIManager.m 中有一个注册和 loginWithUserName 方法。在 loginWithUserName 方法中，我像这样设置 cookie:

if ([[responseObject objectForKey:@"status_code"] isEqualToString:kStatusOk]) {
    NSArray *cookies = [[NSHTTPCookieStorage sharedHTTPCookieStorage] cookies];
    self.cookie = cookies[0];
    NSLog(@"%@", self.cookie);
    NSData *cookiesData = [NSKeyedArchiver archivedDataWithRootObject:self.cookie];
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:cookiesData forKey:@"savedCookie"];
    [defaults synchronize];
    NSLog(@"%@ \n\n\n RESPONSE OBJECT Obtained \n\n\n",responseObject);
    succes(responseObject);
} else {
    failure(responseObject);
}

我有一个方法来加载保存的 cookie(我在登录或注册后在我的 appDelegate 中使用这个方法):

(BOOL) loadSavedAuthCookie {
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    NSData *cookieData = [defaults dataForKey:@"savedCookie"];
    if (cookieData) {
        id cookie = [NSKeyedUnarchiver unarchiveObjectWithData:cookieData];
        if ([cookie isKindOfClass:[NSHTTPCookie class]]) {
            [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];
            return YES;
        }
        else return NO;
    }
    else return NO;
}

我想创建一个注销按钮，我的 APIManager.m 中需要一个方法来删除 cookie。

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