我正在尝试将 UrbanAirship 集成到我的应用程序中，并且一直遇到以下错误：

这是我为它编写的代码：
UAConfig *config = [UAConfig defaultConfig];
[UAirship takeOff:config];
[UAPush shared].notificationTypes = (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeNewsstandContentAvailability);
[[UAPush shared] setPushEnabled:YES];
.plist 已经有了正确的密钥，并且我已经在苹果注册了我的捆绑 ID。还有什么我想念的吗？我浏览了 5 次文档。
