操作button不会出现在通知iOS 10中

我在我的应用程序中使用本地推送通知。 当在iOS 10中添加通知的操作button时，它不会显示在通知下方。 通知正在出现，但通知底部的操作button已丢失。 appdelegate代码如下。

import UIKit import CoreData import UserNotifications @UIApplicationMain class AppDelegate: UIResponder, UIApplicationDelegate { var window: UIWindow? func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { // Override point for customization after application launch. UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound]) {(accepted, error) in if !accepted { print("Notification access denied.") } } let action = UNNotificationAction(identifier: "markCompleted", title: "Mark as Completed", options: []) let category = UNNotificationCategory(identifier: "todoList", actions: [action], intentIdentifiers: [], options: []) UNUserNotificationCenter.current().setNotificationCategories([category]) return true } func applicationWillResignActive(_ application: UIApplication) { // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state. // Use this method to pause ongoing tasks, disable timers, and invalidate graphics rendering callbacks. Games should use this method to pause the game. } func applicationDidEnterBackground(_ application: UIApplication) { // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later. // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits. } func applicationWillEnterForeground(_ application: UIApplication) { // Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background. } func applicationDidBecomeActive(_ application: UIApplication) { // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface. } func applicationWillTerminate(_ application: UIApplication) { // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:. // Saves changes in the application's managed object context before the application terminates. self.saveContext() } // MARK: - user defined functions func notifyWithinApp(_ message: String) { Utils.sharedInstance.notifyLocally(message) } func scheduleNotification(at date: Date, body: String) { let calendar = Calendar(identifier: .gregorian) let components = calendar.dateComponents(in: .current, from: date) let newComponents = DateComponents(calendar: calendar, timeZone: .current, month: components.month, day: components.day, hour: components.hour, minute: components.minute) let trigger = UNCalendarNotificationTrigger(dateMatching: newComponents, repeats: false) let content = UNMutableNotificationContent() content.title = "Dont Forget" content.body = body content.sound = UNNotificationSound.default() content.categoryIdentifier = "todoList" let request = UNNotificationRequest(identifier: "textNotification", content: content, trigger: trigger) UNUserNotificationCenter.current().delegate = self //UNUserNotificationCenter.current().removeAllPendingNotificationRequests() UNUserNotificationCenter.current().add(request) {(error) in if let error = error { print("Uh oh! We had an error: \(error)") } } } // MARK: - Core Data stack lazy var persistentContainer: NSPersistentContainer = { /* The persistent container for the application. This implementation creates and returns a container, having loaded the store for the application to it. This property is optional since there are legitimate error conditions that could cause the creation of the store to fail. */ let container = NSPersistentContainer(name: "ListTodo") container.loadPersistentStores(completionHandler: { (storeDescription, error) in if let error = error as NSError? { // Replace this implementation with code to handle the error appropriately. // fatalError() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development. /* Typical reasons for an error here include: * The parent directory does not exist, cannot be created, or disallows writing. * The persistent store is not accessible, due to permissions or data protection when the device is locked. * The device is out of space. * The store could not be migrated to the current model version. Check the error message to determine what the actual problem was. */ fatalError("Unresolved error \(error), \(error.userInfo)") } }) return container }() // MARK: - Core Data Saving support func saveContext () { let context = persistentContainer.viewContext if context.hasChanges { do { try context.save() } catch { // Replace this implementation with code to handle the error appropriately. // fatalError() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development. let nserror = error as NSError fatalError("Unresolved error \(nserror), \(nserror.userInfo)") } } } } @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) { // Print message ID. // Print full message. } func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) { if response.actionIdentifier == "markCompleted" { } } } 

Answer 1

button不会自行显示。 在支持的设备上，您必须3D触摸通知以显示内容或button。 在不支持的设备上，您可以尝试向下或向左/向右滑动button以显示。

希望这可以帮助。 🙂

Answer 2

其实我没有刷通知。 那么我发现只有当你滑动通知button才会出现。 苹果的糟糕的UI / UXdevise。

Answer 3

面临同样的问题。 3D触摸function的可用性对于显示button至关重要。 在iPhone 5s模拟器中运行您的应用程序 – 在将通知滑动到左侧后，将出现button。
