解决方式：
info.plist 文件添加权限请求
NSUserTrackingUsageDescription xxx需要使用你的广告追踪权为您提供更精准的服务

AppDelegate
   func applicationDidBecomeActive(_ application: UIApplication) {
       if #available(iOS 14.0, *) {
           ATTrackingManager.requestTrackingAuthorization { (status: ATTrackingManager.AuthorizationStatus) in
               // ...
           }
         }
     }

SceneDelegate:
 func sceneDidBecomeActive(_ scene: UIScene) {
        if #available(iOS 14, *){
            DispatchQueue.global().asyncAfter(deadline: .now() + 1) {
                       ATTrackingManager.requestTrackingAuthorization { (status: ATTrackingManager.AuthorizationStatus) in
                           switch status {
                           case .notDetermined:
                               NSLog("--申请tracking权限，用户为做选择或未弹窗")
                               break
                           case .authorized:
                               NSLog("--用户允许广告追踪")
                               break
                           case .denied:
                               NSLog("--用户拒绝广告id")
                               break
                           case .restricted:
                               NSLog("--restricted")
                               break
                           @unknown default:
                               NSLog("--unknown")
                           }
                      }
                   }
        }else{
            if ASIdentifierManager.shared().isAdvertisingTrackingEnabled == true {
                let idfa = ASIdentifierManager.shared().advertisingIdentifier
                NSLog("允许广告追踪 idfa:\(idfa)")
            }else{
               NSLog("用户限制了广告追踪")
            }
        }
        
        // Called when the scene has moved from an inactive state to an active state.
        // Use this method to restart any tasks that were paused (or not yet started) when the scene was inactive.
    }

即使在applicationDidBecomeActive里面调用ATTrackingManager还是无法弹窗？
看看设置-隐私-跟踪，是否是打开的，自己关闭了，所以无论怎么都不会有弹窗
