【中文标题】在 Swift 3 中，申请为 ios 8.1 注册通知

【英文标题】：In Swift 3, Application filed to register notification for ios 8.1

【发布时间】：2017-09-20 04:27:48

【问题描述】：

以下是应用程序抛出错误注册通知时的错误详情：

<EXPR>:3:1: error: expected member name or constructor call after type name
Error
^

<EXPR>:3:1: note: use '.self' to reference the type object
Error
^
 .self

这是在 ios 10.1 中成功运行的代码

func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error)

    print("Failed to register Notification Error  = ", Error)        


func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)

    print("Device Token = ", Data) 




func registerForRemoteNotification()

    if #available(iOS 10.0, *)
    

        let center  = UNUserNotificationCenter.current()
        center.delegate = self
        center.requestAuthorization(options: [.sound, .alert, .badge])
         (granted, error) in
            if error == nil
            
                UIApplication.shared.registerForRemoteNotifications()


            
        
    
    else
    
        if #available(iOS 8.0, *)
        
            UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.sound, .alert, .badge], categories: nil))
            UIApplication.shared.registerForRemoteNotifications()

        
        else
        
           UIApplication.shared.registerForRemoteNotifications(matching: [.badge, .sound, .alert])
        
    

@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void)


    if let dicAps = notification.request.content.userInfo["aps"] as? NSDictionary
    
        AppUtilities.showAlertWithMessage(title: APP_TITLE as NSString, message: "\(dicAps.object(forKey: "msg")!)" as NSString)
    
    completionHandler([.alert, .badge, .sound])


//Called to let your app know which action was selected by the user for a given notification.
@available(iOS 10.0, *)
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void)

    print("User Info = ",response.notification.request.content.userInfo)

我正在尝试实现一个可以在 iOS 8 到 10.1 上运行的应用程序。它在 iOS 10.1.1 的 iPhone 5s 上运行良好。但是当我在iOS 8.1的模拟器中运行该应用程序时，它总是会抛出上述错误，如果我遗漏了什么，请纠正我。

谢谢。

【问题讨论】：

哪些行导致错误？

@JK Patel：推送通知在模拟器中不起作用，***.com/questions/21741259/…

@rmaddy 我在模拟器中运行应用程序时从 didFailToRegisterForRemoteNotificationsWithError 收到错误。

【参考方案1】：

很抱歉，您需要找到一些硬件来测试此功能。

推送通知在模拟器中不可用。它们需要来自 iTunes Connect 的配置文件，因此需要安装在设备上。这也意味着你可能必须被苹果 iPhone 开发者计划接纳并支付 99 美元。

我正在查看苹果开发者文档以了解此错误。
