一个信号 - idsAvailable 已弃用答案

【问题描述】：

OneSignal 的最新构建版本生成警告，如“idsAvailable”已弃用。如何使用 getPermissionSubscriptionState() 而不是 idsAvailable 获取“playerID”，如下所示？

    OneSignal.idsAvailable({ (userId, pushToken) in

        if (pushToken != nil) {

            if let playerID = userId {

                // do something

            }
        }
    })

OneSignal 保留了非常好的文档。

对于android，您可以使用idsAvailable 方法获取用户ID，该方法返回用户ID 和注册ID。

userID aka playerID 是 OneSignal UUID 格式的字符串。（每个应用每个设备唯一） registrationID 是 Google 分配的标识符（每个设备每个应用程序和重新安装时的更改都是唯一的）。

对于 iOS，您可以通过相同的方式获取用户 ID，但在原生 iOS SDK 版本 2.5.0+ 中添加了 getPermissionSubscriptionState 方法和 addSubscriptionObserver。

您可以按如下方式获取 Swift 的 OSPermissionSubscriptionState：

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
print("userID = \(userID)")
let pushToken = status.subscriptionStatus.pushToken
print("pushToken = \(pushToken)")

对于 Objective-C：

OSPermissionSubscriptionState* status = [OneSignal getPermissionSubscriptionState];
status.permissionStatus.hasPrompted
status.permissionStatus.status

status.subscriptionStatus.subscribed
status.subscriptionStatus.userSubscriptionSetting
status.subscriptionStatus.userId
status.subscriptionStatus.pushToken

所以你上面的代码现在看起来像这样：

let status: OSPermissionSubscriptionState = OneSignal.getPermissionSubscriptionState()

let userID = status.subscriptionStatus.userId
    print("userID = \(userID)")
let pushToken = status.subscriptionStatus.pushToken
    print("pushToken = \(pushToken)")

if pushToken != nil {
    if let playerID = userID {
        // do something
    }
}

我刚刚在文档中发现，看起来“userID”的意思是“playerID”。

【解决方案3】：

userId 与 playerId 相同，将它们放在我在 Swift 4 应用程序中使用的一些示例分析（单例）类中：

class Analytics : NSObject, OSSubscriptionObserver {

    ///the singleton
    static let shared = Analytics()


    func setupOneSignal(launchOptions: [UIApplicationLaunchOptionsKey : Any]?) {
        OneSignal.setLogLevel(.LL_VERBOSE, visualLevel: .LL_NONE)
        OneSignal.add(self as OSSubscriptionObserver)

        let settings : [String : Any] = [kOSSettingsKeyInAppLaunchURL : false]
        OneSignal.initWithLaunchOptions(
            launchOptions,
            appId:Environment.oneSignalAppId,
            handleNotificationReceived: {
                (osnotification) in
               //.....
        },
            handleNotificationAction: {
                (osNotificationOpenedResult) in
               //.....

        },
            settings: settings)
    }

    func onOSSubscriptionChanged(_ stateChanges: OSSubscriptionStateChanges!) {
        if  let state = OneSignal.getPermissionSubscriptionState(),
            let userId = state.subscriptionStatus.userId,
            let pushToken = state.subscriptionStatus.pushToken {
            print("onesignal.userId : \(userId)")
            print("onesignal.pushToken : \(pushToken)")
        }
    }

}

使用此代码

public class MainActivity extends Activity implements OSSubscriptionObserver {
  protected void onCreate(Bundle savedInstanceState) {
    OneSignal.addSubscriptionObserver(this);
  }
  
  public void onOSSubscriptionChanged(OSSubscriptionStateChanges stateChanges) {
    if (!stateChanges.getFrom().getSubscribed() &&
        stateChanges.getTo().getSubscribed()) {
         new AlertDialog.Builder(this)
             .setMessage("You've successfully subscribed to push notifications!")
             .show();
        // get player ID
        stateChanges.getTo().getUserId();
      }
   
      Log.i("Debug", "onOSSubscriptionChanged: " + stateChanges);
  }
}
