当应用程序在 iOS 中处于运行状态时检测推送通知选择

Question

我正在使用didReceiveRemoteNotification 来检测应用通知。但是当应用程序处于运行状态时，它会自动触发。我需要在应用程序处于运行状态时检测到通知选择，而不是通过didReceiveRemoteNotification 自动检测通知。提前致谢

当应用在前台运行时，iOS 10+ 提供了自定义本地通知来处理此类问题。

在didFinishLaunchingWithOptions，添加委托

    UNUserNotificationCenter.current().delegate = self

然后创建一个 appDelegate 扩展并添加它。

@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {

// Receive displayed notifications for iOS 10 devices.
func userNotificationCenter(_ center: UNUserNotificationCenter,
                            willPresent notification: UNNotification,
                            withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
    let userInfo = notification.request.content.userInfo



    // Print full message.
    print(userInfo)

    // Change this to your preferred presentation option
    completionHandler([.alert,.sound])
}

func userNotificationCenter(_ center: UNUserNotificationCenter,
                               didReceive response: UNNotificationResponse,
                               withCompletionHandler completionHandler: @escaping () -> Void) {
       let userInfo = response.notification.request.content.userInfo


       // Print full message.
       print("tap on on forground app",userInfo)

       completionHandler()
   }

}
