ios - 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 用户的唯一播放器 ID？我只在 OneSignal 官方文档中找到了 iOS SDK 设置。

如有建议，不胜感激。

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)")
      }
   }
}
