苦苦于解决这个问题并且不愿实施自定义cookie管理系统.

看来iOS的一些隐藏级别的HTTP实现无法正确管理无会话cookie.每当HTTP响应设置或删除cookie时,立即检查NSHTTPCookieStorage cookie将产生预期结果并指示正确的sessionOnly值.

但是,如果应用程序在响应更新cookie后立即退出,则重新启动时,这些sessionOnly = FALSE cookie将恢复为某个先前状态,并且最新更新将丢失.

是否通过响应头或NSHTTPCookieStorage setCookie设置/删除cookie:没有区别.

一些缓存/同步伏都教必须在幕后进行.cookie变为持久化所需的时间最长可达5秒.

在那里有谁或者可以指出这种行为的明确解释？这是一个简单明了的bug吗？还是一些我无法理解的无证特征？

您可以使用一些代码重现:

- (void)applicationDidBecomeActive:(UIApplication *)application
{

    [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways];

    NSHTTPCookie *cookie;
    for (cookie in [NSHTTPCookieStorage sharedHTTPCookieStorage].cookies) {
        NSLog(@"%@=%@", cookie.name, cookie.value);
    }

    NSMutableDictionary *cookieProperties = [NSMutableDictionary dictionary];
    [cookieProperties setObject:@"testCookie" forKey:NSHTTPCookieName];
    [cookieProperties setObject:[NSString stringWithFormat:@"%f", [[NSDate date] timeIntervalSince1970]] forKey:NSHTTPCookieValue];
    [cookieProperties setObject:@"www.example.com" forKey:NSHTTPCookieDomain];
    [cookieProperties setObject:@"www.example.com" forKey:NSHTTPCookieOriginURL];
    [cookieProperties setObject:@"/" forKey:NSHTTPCookiePath];
    [cookieProperties setObject:@"0" forKey:NSHTTPCookieVersion];

    // set expiration to one month from now
    [cookieProperties setObject:[[NSDate date] dateByAddingTimeInterval:2629743] forKey:NSHTTPCookieExpires];

    cookie = [NSHTTPCookie cookieWithProperties:cookieProperties];
    [[NSHTTPCookieStorage sharedHTTPCookieStorage] setCookie:cookie];

}

此代码应在每次启动时输出新值.相反,您会看到如果您快速退出应用程序,则值将保持不变. …
