Question

截至目前，我获得推送通知并在前景和后台状态下显示横幅。但是虽然它在后台工作正常但是当我在前台时我无法触发一个动作来打开一个特定的视图控制器一旦我点击横幅（应该只在我点击横幅时打开）。我该怎么做我的代码如下：

func application(_ application: UIApplication,
                     didReceiveRemoteNotification userInfo: [AnyHashable : Any],
                     fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void)
    {

        print("Recived: \(userInfo)")

        completionHandler(.newData)


        if state == .background {
            if mediaId != nil{
                DispatchQueue.main.async {
                    let storyboard = UIStoryboard(name: "Main", bundle: nil)
                    let mP3ViewController = storyboard.instantiateViewController(withIdentifier:"MP3ViewController") as! MP3ViewController
                    mP3ViewController.media_ID = mediaId
                    self.navigationController?.pushViewController(mP3ViewController, animated:true)

                }

            }
        }else if state == .active {
      //What sould i do here to get the click 

            print("Running on foreground")
            UIApplication.shared.applicationIconBadgeNumber = 0
            let count = 0
            UserDefaults.standard.setValue(count, forKey: "PUSH_COUNT")
            UserDefaults.standard.synchronize()


        }

    }

试试这个在UNUserNotificationCenterDelegate班级

中实施AppDelegate

class AppDelegate: UIResponder, UIApplicationDelegate,UNUserNotificationCenterDelegate {
}

在AppDelegate class

中添加bellow方法

    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        print("didReceive response")
        completionHandler()
    }

    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        print("willPresent notification")

        completionHandler([.badge, .alert, .sound])
    }

上面的方法会在推送通知出现在前台时调用。

修改： -

添加由交互式通知委托
调用的此方法
func application(_ application: UIApplication, handleActionWithIdentifier identifier: String?, for notification: UILocalNotification, completionHandler: @escaping () -> Void) { print("identifier = \(identifier)") }

编辑2：

func application(_ application: UIApplication, handleActionWithIdentifier identifier: String?, forRemoteNotification userInfo: [AnyHashable : Any], withResponseInfo responseInfo: [AnyHashable : Any], completionHandler: @escaping () -> Void) { print("identifier = \(identifier)") }

一旦在前景上单击推送通知横幅，如何触发操作
