如何在 iOS 中获取 One Signal 用户的唯一玩家 ID？

Question

如何在 iOS 中检索 OneSignal 用户的唯一玩家 ID？我只在 OneSignal 官方文档中找到 iOS SDK 设置。

如果有任何建议，谢谢。

Answer 1

您需要使用 OneSignal 的观察者，例如 OSSubscriptionObserver.

// Add OSSubscriptionObserver after UIApplicationDelegate
class AppDelegate: UIResponder, UIApplicationDelegate, OSSubscriptionObserver {

   func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
      // Add your AppDelegate as an subscription observer
      OneSignal.add(self as OSSubscriptionObserver)
   }

   // After you add the observer on didFinishLaunching, this method will be called when the notification subscription property changes. 
   func onOSSubscriptionChanged(_ stateChanges: OSSubscriptionStateChanges!) {
      if !stateChanges.from.subscribed && stateChanges.to.subscribed {
         print("Subscribed for OneSignal push notifications!")
      }
      print("SubscriptionStateChange: \n\(stateChanges)")

      //The player id is inside stateChanges. But be careful, this value can be nil if the user has not granted you permission to send notifications. 
      if let playerId = stateChanges.to.userId {
         print("Current playerId \(playerId)")
      }
   }
}

为了更好的解释，这里是 addSubscriptionObserver

Answer 2

您可以在 standardUserDefaults 中找到它。您可以使用以下方法检索它。我相信它是在第一次启动应用程序时设置的，但是，它可能不会在第一次调用 application:didFinishLaunchingWithOptions: 时设置。

UserDefaults.standard.string(forKey: "GT_PLAYER_ID")

您可以通过查看字典表示来了解用户默认值中还存储了什么：UserDefaults.standard.dictionaryRepresentation()

Answer 3

我确实需要在代码中的某处获取玩家 ID（或用户 ID），但我不想将其保存在任何地方。

我最终使用了这段代码：

let userId = OneSignal.getPermissionSubscriptionState().subscriptionStatus.userId

Answer 4

    let status: OSPermissionSubscriptionState = OneSignal.getPermissionSubscriptionState()

    let hasPrompted = status.permissionStatus.hasPrompted
    print("hasPrompted = \(hasPrompted)")
    let userStatus = status.permissionStatus.status
    print("userStatus = \(userStatus)")

    let isSubscribed = status.subscriptionStatus.subscribed
    print("isSubscribed = \(isSubscribed)")
    let userSubscriptionSetting = status.subscriptionStatus.userSubscriptionSetting
    print("userSubscriptionSetting = \(userSubscriptionSetting)")
    let userID = status.subscriptionStatus.userId // This one
    print("userID = \(userID)")
    let pushToken = status.subscriptionStatus.pushToken
    print("pushToken = \(pushToken)")
