Parse.com 注册推送通知

Question

我正在尝试使用 Parse.com 推送通知服务向我的 iOS 应用程序添加推送通知，但我运行遇到一些问题，我的一些设备无法接收通知。

当前代码

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    Parse.setApplicationId("*****", clientKey: "*****")

    // Register for Push Notitications
    if application.applicationState != UIApplicationState.Background {
        // Track an app open here if we launch with a push, unless
        // "content_available" was used to trigger a background push (introduced in iOS 7).
        // In that case, we skip tracking here to avoid double counting the app-open.

        let preBackgroundPush = !application.respondsToSelector("backgroundRefreshStatus")
        let oldPushHandlerOnly = !self.respondsToSelector("application:didReceiveRemoteNotification:fetchCompletionHandler:")
        var pushPayload = false
        if let options = launchOptions {
            pushPayload = options[UIApplicationLaunchOptionsRemoteNotificationKey] != nil
        }
        if (preBackgroundPush || oldPushHandlerOnly || pushPayload) {
            PFAnalytics.trackAppOpenedWithLaunchOptions(launchOptions)
        }
    }
    if application.respondsToSelector("registerUserNotificationSettings:") {
        let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()
    }else {
        let types : UIRemoteNotificationType = [.Badge, .Alert, .Sound]
        application.registerForRemoteNotificationTypes(types)
    }
    return true
}

func application(application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    // Store the deviceToken in the current Installation and save it to Parse
    let installation = PFInstallation.currentInstallation()
    installation.setDeviceTokenFromData(deviceToken)
}

func application(application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: NSError) {
    if error.code == 3010 {
        print("Push notifications are not supported in the iOS Simulator.")
    } else {
        print("application:didFailToRegisterForRemoteNotificationsWithError: %@", error)
    }
}

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject]) {
    if application.applicationState == UIApplicationState.Inactive {
        PFAnalytics.trackAppOpenedWithRemoteNotificationPayload(userInfo)
    }
}

这似乎适用于一些设备（在同事的 iPhone 上测试过 5 - 有效，在我老板的 iPhone 上测试过 6 - 没有t 工作）

我目前使用的代码也给了我 2 个警告，这是（我怀疑的）推送通知无法在每个 iDevice 上工作的原因。

警告 1：

/Users/ds/code/rp-iOS/rp/AppDelegate.swift:43:25: 'UIRemoteNotificationType' was deprecated in iOS 8.0: Use UIUserNotificationType for user notifications and registerForRemoteNotifications for receiving remote notifications instead.

第 43 行：

let types : UIRemoteNotificationType = [.Badge, .Alert, .Sound]

警告 2：

/Users/ds/code/rp-iOS/rp/AppDelegate.swift:44:25: 'registerForRemoteNotificationTypes' was deprecated in iOS 8.0: Please use registerForRemoteNotifications and registerUserNotificationSettings: instead

第 44 行：

application.registerForRemoteNotificationTypes(types)

现在我对这些警告感到困惑，因为我从 Parse.com 文档中复制了代码 - 那么我做错了什么？似乎这个 else 子句为运行旧版本 iOS 的设备提供了向后兼容性。

在我的 Parse.com 推送控制台中，我也遇到了一些错误：

如有任何帮助，我们将不胜感激。

Answer 1

在didRegisterForRemoteNotificationsWithDeviceToken中尝试添加这行代码。

installation.saveInBackground()

为了消除警告，我建议使用此代码（为了方便和重复使用，我将其放在静态函数中）

static func askForPushNotifications(){
  let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
  UIApplication.sharedApplication().registerUserNotificationSettings(settings)
  UIApplication.sharedApplication().registerForRemoteNotifications()
}
