ios - isRegisteredForRemoteNotifications 返回 true 即使我完全禁用它

Question

if UIApplication.sharedApplication().isRegisteredForRemoteNotifications() == true {
    println("Yes, allowed")
    println(UIApplication.sharedApplication().isRegisteredForRemoteNotifications())
} else {
    //ignore
    return
}

当我转到设置以完全关闭通知然后返回应用程序时，该应用程序仍然打印 true, allowed。

我似乎无法让它触发 false，即使在应用程序卸载/重新安装之后也是如此。

我为 Swift 3 做了一个扩展

extension UIApplication {
    func remoteNotificationsEnabled() -> Bool {
        var notificationsEnabled = false
        if let userNotificationSettings = currentUserNotificationSettings {
            notificationsEnabled = userNotificationSettings.types.contains(.alert)
        }
        return notificationsEnabled
    }
}

比起使用它

UIApplication.shared.remoteNotificationsEnabled()
