致电

UIUserNotificationType types = UIUserNotificationTypeAlert;

UIUserNotificationSettings *settings = [UIUserNotificationSettings settingsForTypes:types categories:nil];

[[UIApplication sharedApplication] registerUserNotificationSettings:settings];

在

- (void)application:(UIApplication *)application didRegisterUserNotificationSettings:(UIUserNotificationSettings *)notificationSettings

我永久得到所有类型的 notificationSettings

<UIUserNotificationSettings: 0x16dd6160; types: (UIUserNotificationTypeAlert UIUserNotificationTypeBadge UIUserNotificationTypeSound);>

UIUserNotificationSettings *settings = [[UIApplication sharedApplication] currentUserNotificationSettings]

所以我不能设置上开始限制动力的权限。

So I can't setup restricted dynamical permissions on start.

推荐答案

看来，这是不可能的iOS8上设置 UserNotificationType 从应用程序（至少）。人们需要使用一般的通知中心设置声音，徽章和警报的任意组合。仅注册这第一次尝试用推送通知的权限警惕发生套 UserNotificationType 必要的。

It seems that it is impossible to setup UserNotificationType from application in iOS8 (at least). One needs to use general Notification Center to set any combination of sound, badge and alert. Only the first attempt to register which occurs with Push notification permissions alert sets UserNotificationType needed.

另一种方式是发送 UserNotificationType 上订阅推送服务​​器负载取决于这种类型的应该做。

Another way is to send UserNotificationType on subscription to your push server which should make payload depending of this type.
