解析ios 9 Swift 2-應用程序委托錯誤

Question

Parse的文檔代碼當前是否不是針對iOS 9 Swift 2 xcode 7.1的最新版本？ 最后兩個函數都有錯誤，提示“定義與先前值沖突”

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

    Parse.setApplicationId("key",
        clientKey: "key")

    // 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)
        }
    }

    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.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]) {
        PFPush.handlePush(userInfo)
        if application.applicationState == UIApplicationState.Inactive {
            PFAnalytics.trackAppOpenedWithRemoteNotificationPayload(userInfo)
        }
    }

Answer 1

最后三個函數應該在didFinishLaunchingWithOptions函數之外。
