使用未声明的类型UNAuthorizationOptions

Question

我正在尝试使用Firebase来处理推送通知.我安装了Firebasepod('Firebase/Core'和'FirebaseMessaging'pods).

在我将Firebase导入项目之后

import Firebase

我已经像这样配置了Firebase应用程序(代码是从官方文档中复制的):

  func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?)
-> Bool {FIRApp.configure() }

之后,我尝试使用此代码(代码从官方文档复制):

if #available(iOS 10.0, *) {
            let authOptions : UNAuthorizationOptions = [.alert, .badge, .sound]
            UNUserNotificationCenter.current().requestAuthorization(
                options: authOptions,
                completionHandler: {_,_ in })

            // For iOS 10 display notification (sent via APNS)
            UNUserNotificationCenter.current().delegate = self
            // For iOS 10 data message (sent via FCM)
            FIRMessaging.messaging().remoteMessageDelegate = self

        } else {
            let settings: UIUserNotificationSettings =
                UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
            application.registerUserNotificationSettings(settings)
        }

        application.registerForRemoteNotifications()

但是我从标题中得到了错误:

使用未声明的类型UNAuthorizationOptions

我也有与UNUserNotificationCenter班级相关的错误.

我使用的是Swift 2.2和Xcode 7.3.1

这个错误的原因是什么？

Answer 1

你需要import UserNotifications在调用这些框架之前.而且Nirav D所说的是真的,它是iOS 10中的一个新框架,也应该记得选择正确的部署目标.

Answer 2

UserNotifications.framework可以从iOS 10获得,你使用Xcode 7.3意味着iOS 9及更低版本,所以你不需要添加它if #available(iOS 10.0, *) {,直接写其他部分并注册远程通知.

let settings: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
application.registerUserNotificationSettings(settings)
application.registerForRemoteNotifications()
