引入庫

import UserNotifications

首先注冊 注冊方法 放置到這里

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {}

注冊方法

    //MARK:  注冊推送
    func registerNotifications(_ application: UIApplication) {
        //-- 注冊推送
        if #available(iOS 10.0, *) {
            let center = UNUserNotificationCenter.current()
            center.delegate = self as UNUserNotificationCenterDelegate
            center.getNotificationSettings { (setting) in
                if setting.authorizationStatus == .notDetermined{
                    // 未注冊
                    center.requestAuthorization(options: [.badge,.sound,.alert]) { (result, error) in
                        print("顯示內(nèi)容：\(result) error：\(String(describing: error))")
                        if(result){
                            if !(error != nil){
                                print("注冊成功了场躯！")
                                application.registerForRemoteNotifications()
                            }
                        } else{
                            print("用戶不允許推送")
                        }
                    }
                } else if (setting.authorizationStatus == .denied){
                    //用戶已經(jīng)拒絕推送通知
                    //-- 彈出頁面提示用戶去顯示
                    
                }else if (setting.authorizationStatus == .authorized){
                    //已注冊 已授權(quán) --注冊同志獲取 token
                    self.registerForRemoteNotifications()
                }else{
                    
                }
            }
        }
        
    }

    // 注冊通知牲芋，獲取deviceToken
    func registerForRemoteNotifications() {
        // 請求授權(quán)時異步進行的闸餐，這里需要在主線程進行通知的注冊
        DispatchQueue.main.async {
            UIApplication.shared.registerForRemoteNotifications()
        }
    }

成功與失敗的回調(diào)

    // 成功的回調(diào)
    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        //TODO: 注冊遠程通知, 將deviceToken傳遞過去
        let deviceStr = deviceToken.map { String(format: "%02hhx", $0) }.joined()
        
        print(deviceStr)
    }
    
    func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
        
    }
    
    //失敗的回調(diào)
    func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
        //TODO: 注冊失敗后的結(jié)果, 可以在這里記錄失敗結(jié)果, 以后再伺機彈框給用戶打開通知
        
    }

delegate

extension AppDelegate:UNUserNotificationCenterDelegate{
    
    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        
    }
    
    func userNotificationCenter(_ center: UNUserNotificationCenter, openSettingsFor notification: UNNotification?) {
        
    }
    
    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        
    }
}

簡單明了復制即可
