如何处理iOS 10中的UserNotifications *** 作

概述所以我可以安排这样的通知; //iOS 10 Notificationif #available(iOS 10.0, *) { var displayDate: String { let dateFormatter = DateFormatter() dateFormatter.dateStyle = DateFormatter.Style.full 所以我可以安排这样的通知;

//iOS 10 Notificationif #available(iOS 10.0,*) {    var displayDate: String {        let dateFormatter = DateFormatter()        dateFormatter.dateStyle = DateFormatter.Style.full        return dateFormatter.string(from: datePicker.date as Date)    }    let notif = UNMutableNotificationContent()    notif.Title = "I am a Reminder"    notif.subTitle = "\(displayDate)"    notif.body = "Here's the body of the notification"    notif.sound = UNNotificationSound.default()    notif.categoryIDentifIEr = "reminderNotification"    let today = NSDate()    let interval = datePicker.date.timeIntervalSince(today as Date)    let notifTrigger = UNTimeIntervalNotificationTrigger(timeInterval: interval,repeats: false)    let request = UNNotificationRequest(IDentifIEr: "reminderNotif",content: notif,trigger: notifTrigger)    UNUserNotificationCenter.current().add(request,withCompletionHandler: { error in        if error != nil {            print(error)           // completion(Success: false)        } else {            //completion(Sucess: true)        }        })}

我已经在appDelegate中请求了权限,并且使用通知扩展程序的自定义视图显示通知正常.

我在appDelegate中为通知类别添加了通知 *** 作;这些也出现了.

//Notifications Actions private func configureUserNotifications() {    if #available(iOS 10.0,*) {        let tomorrowAction = UNNotificationAction(IDentifIEr: "tomorrowReminder",Title: "Remind Me Tomorrow",options: [])        let dismissAction = UNNotificationAction(IDentifIEr: "dismissReminder",Title: "dismiss",options: [])        let category = UNNotificationcategory(IDentifIEr: "reminderNotification",actions: [tomorrowAction,dismissAction],intentIDentifIErs: [],options: [.customdismissAction])        UNUserNotificationCenter.current().setNotificationCategorIEs([category])    } else {        // Fallback on earlIEr versions    }}

我在通知扩展名.pList文件中设置了相同的类别.在通知扩展中,我有以下内容在用户点击 *** 作时更改文本.

//Handle Notification Actions And Update Notification Window  private func dIDReceive(_ response: UNNotificationResponse,completionHandler done: (UNNotificationContentExtensionResponSEOption) -> VoID) {    if response.actionIDentifIEr == "tomorrowReminder" {        print("Tomrrow button pressed")        subLabel.text = "Reminder For Tomorrow"        subLabel.textcolor = UIcolor.blue        done(.dismissAndForwardAction)    }    if response.actionIDentifIEr == "dismissReminder" {        print("dismiss button pressed")        done(.dismiss)    } else {        print("Else response")        done(.dismissAndForwardAction)    }}

但是,文本没有改变,也没有调用任何语句;

在appDelegate中我有以下内容;

func application(_ application: UIApplication,dIDFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey : Any]? = nil) -> Bool {    if #available(iOS 10.0,*) {        UNUserNotificationCenter.current().delegate = self        configureUserNotifications()    }}extension AppDelegate: UNUserNotificationCenterDelegate {@available(iOS 10.0,*)private func userNotificationCenter(_ center: UNUserNotificationCenter,willPresent notification: UNNotification,withCompletionHandler completionHandler: (UNNotificationPresentationoptions) -> VoID) {    completionHandler([.alert,.sound])}@available(iOS 10.0,dIDReceive response: UNNotificationResponse,withCompletionHandler completionHandler: () -> VoID) {    print("RecIEved Action For \(response.actionIDentifIEr)")    if response.actionIDentifIEr == "tomorrowReminder" {        print("Tomorrow Reminder")        //Set new reminder for tomorrow using the notification content Title        completionHandler()    }    if response.actionIDentifIEr == "dismissReminder" {        print("dismiss Reminder...")        completionHandler()    }}}

这些函数都不是在appDelegate中实际调用的.我不确定更新扩展视图的问题是否与应用程序委托有关.我不这么认为,我已经关注了Apple的WWDC视频以及其他教程并查看了文档API并且无法弄清楚;

>为什么通知扩展文本标签不更新？
>为什么appDelegate中的函数没有被调用？
>我如何使用app delegate中的通知内容来使用
为了行动？

PS：过去几周我一直在研究并试图解决这个问题,看起来相当直接,我不确定我错过了什么.我知道我不是唯一有这些问题的人.

解决方法 我没有检查你的整个代码,但至少,这些函数头需要改变如下：

func userNotificationCenter(_ center: UNUserNotificationCenter,withCompletionHandler completionHandler: @escaPing (UNNotificationPresentationoptions) -> VoID) {func userNotificationCenter(_ center: UNUserNotificationCenter,withCompletionHandler completionHandler: @escaPing () -> VoID) {func dIDReceive(_ response: UNNotificationResponse,completionHandler done: @escaPing (UNNotificationContentExtensionResponSEOption) -> VoID) {

简单的规则：
删除私有,添加@escaPing.

您可能从Xcode收到了错误的建议,但是如果将它们设为私有,则不会生成Objective-C入口点. iOS运行时在内部使用Objective-C选择器,因此无法找到您的方法,因此它们不会被执行.
