ios Swift GCM注册令牌为零

我究竟做错了什么？它打印出我的registrationToken是NIL，虽然它也成功打印出注册到GCM .

我正在尝试连接到GCM，我已经设置了SENDER-ID和SENDER ID，现在有什么问题了吗？

Setting up a GCM Client App on iOS它说：

如果注册成功，InstanceID将使用有效的注册令牌和nil错误对象调用registrationToken处理程序 . 如果注册失败，则注册令牌为nil并返回有效的错误对象 . 有关错误代码的详细信息，请参阅GGLInstanceID.h . 注册失败时，客户端应用程序应实施指数退避以重试 .

我得到输出 nil error object 但也有nil注册令牌 .
