iOS和对应的复杂功能不能相互通信

Question

我的App的基本概念是Complication向iPhone请求数据，然后iPhone将数据发回。 我在didFinishLaunchingWithOptions的iPhone应用程序中激活了我的WCSession。另外在我的Watch应用程序中，我已经覆盖了ExtensionDelegate中的init()。

这是我的iPhone单身人士：

class WatchConnectivityManager: NSObject, WCSessionDelegate {

   static let sharedManager = WatchConnectivityManager()

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

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

  func startSession() {
       print("session started")
       session?.delegate = self
       session?.activateSession()
   }

   func session(session: WCSession, didReceiveUserInfo userInfo: [String : AnyObject]) {
       print("didReceiveUserInfo")
       session.transferCurrentComplicationUserInfo(["reply":""])
   }
}

这是我手表中的单身人士：

class WatchConnectivityManager: NSObject, WCSessionDelegate {

   static let sharedManager = WatchConnectivityManager()

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

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

   func startSession() {
       print("session started")
       session?.delegate = self
       session?.activateSession()
   }

   func session(session: WCSession, didReceiveUserInfo userInfo: [String : AnyObject]) {
       print("didReceiveUserInfo")
   }

   func requestData() {
       print("data requested")
       session!.transferUserInfo(["request" : ""])
   }
}

在我的ExtensionDelegate的init中，当我激活我的复杂功能时应调用它，我调用startSession和requestData：

class ExtensionDelegate: NSObject, WKExtensionDelegate {

   override init() {
       WatchConnectivityManager.sharedManager.startSession()
       WatchConnectivityManager.sharedManager.requestData()
   }

   func applicationDidFinishLaunching() {}

   func applicationDidBecomeActive() {}

   func applicationWillResignActive() {}

}

来自我iPhone的AppDelegate：

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    WatchConnectivityManager.sharedManager.startSession()
    return true
}

输出只是：

session started
data requested

当我在XCode中的模拟器上调试复杂时，

没有didReceiveUserInfo。
