iOS 10.3 某些机型设置 Cookies 无效

如下一个 普通的 Cookie 的设置，其实来说是太正常不过了

NSHTTPCookie *cookie = [[NSHTTPCookie alloc] initWithProperties:@{
                                                            NSHTTPCookieName: @"staging",
                                                            NSHTTPCookieValue: @"true",
                                                            NSHTTPCookieDomain: url.host,
                                                            NSHTTPCookiePath: url.path,
                                                }];
NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
[storage setCookie:cookie];

但我们有两个测试机 确实无效的, 发现设置完成后 cookies 中居然没有上述刚刚设置的

po [NSHTTPCookieStorage sharedHTTPCookieStorage].cookies

当然如果监听其 Cookies 变化则可以通过 NSHTTPCookieManagerCookiesChangedNotification 来监听。

后来发现

NSHTTPCookie *releaseCookie = [[NSHTTPCookie alloc] initWithProperties:@{
                                                          NSHTTPCookieName: @"staging",
                                                          NSHTTPCookieValue: @"true",
                                                          NSHTTPCookieDomain: url.host,
                                                          NSHTTPCookiePath: @"/",
                                                           }];

改了一下 Cookie 这个 NSHTTPCookiePath 值 "/ "就可以了 , 因为之前我们的此值为 “” 空。
