ios - WatchKit 数据不显示

Question

我正在将数据从 iOS 传递到 WatchKit。 但我无法获得显示在 WatchKit 端收到的数据。

这很好用:iOS TableViewController

func getCloudKit() {
    ///...
    let publicData = container.publicCloudDatabase
    publicData.performQuery(query, inZoneWithID: nil) { results, error in
        if error == nil { // There is no error
            for play in results! {
                let newPlay = Play()
                    newPlay.tColor = play["TColor"] as! String

                do {
                    try WatchSessionManager.sharedManager.updateApplicationContext(["color" : newPlay.tColor])
                    NSLog("NewPColor: %@", newPlay.tColor)
                } catch {
                    print(error)
                }
                self.objects.append(newPlay)
            }
        } else {
            print(error)
        }
    }
}

这不是调用任何 NSLog 或显示任何数据:WatchKit InterfaceController

import WatchConnectivity


class InterfaceController: WKInterfaceController, WCSessionDelegate {

    @IBOutlet var colorLabel: WKInterfaceLabel!

    private let session: WCSession? = WCSession.isSupported() ? WCSession.defaultSession() : nil

    private func configureWCSession() {
        session?.delegate = self;
        session?.activateSession()
    }

    override init() {
        super.init()
        configureWCSession()
    }

    override func awakeWithContext(context: AnyObject?) {
        super.awakeWithContext(context)
    }

    func session(session: WCSession, didReceiveApplicationContext applicationContext: [String : AnyObject]) {
        let colorWatch = applicationContext["color"] as? String
        NSLog("Check if anything here: %@", colorWatch!)

                dispatch_async(dispatch_get_main_queue()) {
                    if let colorWatch = colorWatch {
                        self.colorLabel.setText("From iPhone: \(colorWatch)")
                        NSLog("Heres all the strings %@", colorWatch)
                    } else {
                        NSLog("Nothing")
                    }
                }
    }


}

有什么想法吗？谢谢!

尝试检查 session 是否为零(我的 swift foo 很弱):

  private func configureWCSession() {
    print("session: \(session?))
    session?.delegate = self;
    session?.activateSession()
}
