Swift with Parse：向appDelegate添加推送通知支持時出錯

Question

我正在嘗試使用Swift向我的appDelegate添加解析。 我說錯了

無法使用類型為（（UIUserNotificationType））的參數列表調用'registerForRemoteNotifications'

這是我的代碼。 怎么了？

    if application.respondsToSelector("registerUserNotificationSettings:") {
        let userNotificationTypes = UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound
        let settings = UIUserNotificationSettings(forTypes: userNotificationTypes, categories: nil)
        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()
    } else {
        let types = UIUserNotificationType.Badge | UIUserNotificationType.Alert | UIUserNotificationType.Sound
        application.registerForRemoteNotifications(types)
    }
    return true

在遵循了Parse教程以使用Apple Developer Console設置推送通知和證書之后，請確保您的AppDelegate.swift如下所示：

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

    Parse.setApplicationId("ID", clientKey:"KEY")

    let userNotificationTypes = (UIUserNotificationType.Alert |
        UIUserNotificationType.Badge |
        UIUserNotificationType.Sound);

    let settings = UIUserNotificationSettings(forTypes: userNotificationTypes, categories: nil)
    application.registerUserNotificationSettings(settings)
    application.registerForRemoteNotifications()

    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)
    installation.addUniqueObject("Chat", forKey: "channels")
    installation.saveInBackground()
}

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)
    }
}

當用戶打開應用程序時，此最后一個功能將重置徽章計數器：

func applicationDidBecomeActive(application: UIApplication) {
    //Reset badge counter to zero
    var currentInstallation = PFInstallation.currentInstallation()
    if(currentInstallation.badge != 0){
        currentInstallation.badge = 0
    }
}

Answer 2

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

如果您使用的是Swift 2.0，這可能會很有用，因為某些錯誤提示

二進制運算符不能應用於兩個UIUserNotificationType
