iOS 上不显示应用程序跟踪透明度对话框

Question

由于 ATT 请求未出现，Apple 审核人员刚刚拒绝了我的应用程序：“在 iOS 15.0.1 上审核时，我们无法找到应用程序跟踪透明度权限请求。”

我的代码如下所示：

if #available(iOS 14, *) {
  ATTrackingManager.requestTrackingAuthorization { (status) in
    //print("IDFA STATUS: \(status.rawValue)")
    FBAdSettings.setAdvertiserTrackingEnabled(true)
  }
}

我在 AppDelegatedidFinishLaunchingWithOptions和viewDidLoad. ATT 权限请求出现在 iOS 14 上，但不在 iOS 15 中。

该死的，我修复了它:( 这都是关于 iOS 警报系统的。在提出通知请求后，我请求应用程序跟踪透明度。一旦通知请求警报关闭，ATT 警报就需要出现。它在 iOS 上运行良好14，但在 iOS 15 上，要在另一个警报之后显示警报，彼此之间需要有一个延迟时间。

编辑：这是我的代码，分别显示两个警报：

 func setNotification(){
    //Ask for notification permission
    let n = NotificationHandler()
    n.askNotificationPermission {
        //n.scheduleAllNotifications()
        
        //IMPORTANT: wait for 1 second to display another alert
        DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
            if #available(iOS 14, *) {
              ATTrackingManager.requestTrackingAuthorization { (status) in
                //print("IDFA STATUS: \(status.rawValue)")
                //FBAdSettings.setAdvertiserTrackingEnabled(true)
              }
            }
        }
    }
}

为了方便起见，这里是我的 NotificaitionHandler 类：

import UserNotifications

class NotificationHandler{
//Permission function
func askNotificationPermission(completion: @escaping ()->Void){
    
    //Permission to send notifications
    let center = UNUserNotificationCenter.current()
    // Request permission to display alerts and play sounds.
    center.requestAuthorization(options: [.alert, .badge, .sound])
    { (granted, error) in
        // Enable or disable features based on authorization.
        completion()
    }
}

Answer 2

Apple 人员建议您通过applicationDidBecomeActive(_:)in请求AppDelegate。这就是我解决 iOS 问题的方法。

import UIKit
import AppTrackingTransparency

class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate, MessagingDelegate {
    func applicationDidBecomeActive(_ application: UIApplication) {
        if #available(iOS 15.0, *) {
            ATTrackingManager.requestTrackingAuthorization(completionHandler: { status in
                
            })
        }
    }
}

Answer 3

我已更改为从以下位置调用请求

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
}

到

@available(iOS 13.0, *)
func sceneDidBecomeActive(_ scene: UIScene) {
    DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) {
        self.requestPermission()
    }
}

func requestPermission() {
    if #available(iOS 15.0, *) {
            ATTrackingManager.requestTrackingAuthorization(completionHandler: { status in
                switch status {
                case .authorized:
                    // Tracking authorization dialog was shown
                    // and we are authorized
                    print("Authorized")
                case .denied:
                    // Tracking authorization dialog was
                    // shown and permission is denied
                    print("Denied")
                case .notDetermined:
                    // Tracking authorization dialog has not been shown
                    print("Not Determined")
                case .restricted:
                    print("Restricted ")
                @unknown default:
                   
                }
            })
        }
    }
}
