Question

如果应用程序未处于活动状态（甚至不在后台或说已终止），则单击操作按钮 3D Touch中的通知中的聊天时不会调用UNUserNotificationCenter功能。我在Xcode中使用“附加到名称处理”来在应用程序终止时调试应用程序。这是代码：

import UIKit
import Mixpanel
import UserNotifications

@UIApplicationMain

class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        //setup mixpanel

        self.handlePushNotificationWithUserInfo(launchOptions: launchOptions)

        //ask for push notification perms
        return true
    }

当通知弹出窗口（从MixPanel发送）时，首先调用此函数，

致电1：

    func handlePushNotificationWithUserInfo(launchOptions: [NSObject: AnyObject]?) {
        //Handle PushNotification when app is opened
    }

然后它就到了，

致电2：

    //register for notification
    func application(_ application: UIApplication, didRegister notificationSettings: UIUserNotificationSettings) {

        if #available(iOS 10.0, *) {
            let center = UNUserNotificationCenter.current()
            center.requestAuthorization(options: [.alert, .sound]) { (granted, error) in
                // Enable or disable features based on authorization.
            }
            center.delegate = self

            let actionChat = UNNotificationAction(identifier: Constants.ActionType.CHAT.rawValue, title: "Chat", options: [.foreground])
            let categoryOptions = UNNotificationCategoryOptions(rawValue: 0)
            let customerSupportCategory = UNNotificationCategory(identifier: Constants.NotificationType.CUSTOMER_SUPPORT.rawValue, actions: [actionChat], intentIdentifiers: [], options: categoryOptions)
            center.setNotificationCategories([customerSupportCategory])
        }

        application.registerForRemoteNotifications()
    }

致电3：

    // remote notification
    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        ....Some Code....
    }

但以下功能未被调用。但是，如果应用程序在后台运行，则会调用以下函数，并且一切正常，否则应用程序进入前台，之后聊天。

    // action buttons in enhanced Notification
    @available(iOS 10, *)
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {
        guard let action = Constants.ActionType(rawValue: response.actionIdentifier) else {
            completionHandler()
            return
        }
        switch action {
        case .CHAT:
            _ = self.handleRemoteUrl(NSURL(string: "chat") as? URL)
        default:
            _ = self.handleRemoteUrl(NSURL(string: "chat") as? URL)
        }
        completionHandler()
    }

    @available(iOS 10.0, *)
    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
        completionHandler([.alert, .sound])
    }
}

这个函数永远不会被调用，因为它在iOS 10中通过userNotificationCenter（）折旧，不确定。请解释一下..

    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
        ....Some Code....
    }

我正在使用iPhone 6s iOS 10作为调试设备。 XCode 8 beta-3

Answer 1

从我自己的实验中，在Swift 3＆amp ;;中接收本地通知Xcode 8如下：

<强>一致性

符合UNUserNotificationCenterDelegate

class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate { .... }

注册为通知中心的代表：

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    let center = UNUserNotificationCenter.current()
    center.delegate = self

    return true
}

委派方法

回复错过的通知（例如，在发送通知时用户查看应用）

func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {
    print(notification.request.content.userInfo)
}

回复已采取行动的通知（例如，用户已打开的通知）

func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {
    print(response.notification.request.content.userInfo)
}

Answer 2

Swift 3.1更新

符合UNUserNotificationCenterDelegate
注册为通知中心的代表：

UNUserNotificationCenter.current().delegate = self

委派方法

public func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
    print(response.notification.request.content.categoryIdentifier)
}

public func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
    print(notification.request.content.categoryIdentifier)
}

Answer 3

当应用未被用户运行或杀死并且收到通知时，在这种情况下，您需要处理didFinishLaunchingWithOptions并检查应用是否通过通知打开并采取适当的行动。

//检查是否从通知

启动

if let notification = launchOptions?[UIApplicationLaunchOptionsRemoteNotificationKey] as? [String: AnyObject] {
       notificationReceived(notification)
    }

如果App终止，则不会调用UNUserNotificationCenter didRecieve Response
