ios - 注册后更新 Parse deviceToken

Question

目前我有很多空的 deviceToken 字段。我发现这是因为在创建安装对象之前添加组存在问题 - 它会阻止后续的创建工作。

我现在想做的是再次获取该 deviceToken 并在 Parse 中更新它，但问题是，didRegisterForRemoteNotificationsWithDeviceToken 在第一次运行后再也不会运行...

在初始调用 didRegisterForRemoteNotificationsWithDeviceToken 之后有什么方法可以获取设备 token ？

这对 iOS 8 有效:

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
    UIUserNotificationSettings* notificationSettings = [UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert | UIUserNotificationTypeBadge | UIUserNotificationTypeSound categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:notificationSettings];
    [[UIApplication sharedApplication] registerForRemoteNotifications];
} else {
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes: (UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound | UIRemoteNotificationTypeAlert)];
}
