如何通过Watch App（Watch OS 2）沟通非活动IOS应用程序

Question

试图将我的Watch OS1应用程序升级到Watch OS 2.创建Watch OS 2的新目标。并使用sendMessage:replyHandler:errorHandler发送/从IOS应用程序获取回复。它工作正常，如果只有IOS应用程序正在运行。如果Watch应用程序在iOS应用程序处于非活动状态（Killed状态）时尝试通信，则连接错误为7001.如何从Watch App（Watch OS 2）通信非活动的IOS应用程序？

这个来自手表应用的sendMessage:replyHandler:errorHandler方法会在后台唤醒相应的iOS应用并使其可达？

谢谢。

EDIT1 -

iOS应用程序的App代表：

- (BOOL)application:(UIApplication*)application didFinishLaunchingWithOptions:(NSDictionary*)launchOptions{ 

    if ([WCSession isSupported]) { 
     WCSession *session = [WCSession defaultSession]; 
     session.delegate = self; 
     [session activateSession]; 
    } 
return YES; 
} 
- (void)session:(nonnull WCSession *)session didReceiveMessage:(nonnull NSDictionary<NSString *,id> *)message replyHandler:(nonnull void (^)(NSDictionary<NSString *,id> * __nonnull))replyHandler { 

     UIApplication *application = [UIApplication sharedApplication]; 
     __block UIBackgroundTaskIdentifier identifier = UIBackgroundTaskInvalid; 
     dispatch_block_t endBlock =^{ 
      if (identifier != UIBackgroundTaskInvalid) { 
       [application endBackgroundTask:identifier]; 
      } 
      identifier = UIBackgroundTaskInvalid; 
     }; 
     identifier = [application beginBackgroundTaskWithExpirationHandler:endBlock]; 

     if (replyHandler!=nil) { 
      replyHandler(resultContainer); // my data dictionary from Iphone app to watch os as reply. 
     } 

     if (identifier!=UIBackgroundTaskInvalid) { 
      [application endBackgroundTask:identifier]; 
      identifier = UIBackgroundTaskInvalid; 
     } 
} 

关注应用：

- (void)applicationDidFinishLaunching { 
    // Perform any final initialization of your application. 
    if ([WCSession isSupported]) { 
     WCSession *session = [WCSession defaultSession]; 
     session.delegate = self; 
     [session activateSession]; 
    } 
     NSDictionary *context = @{@"APP_LOADING":@"LOADING"}; 
     [WKInterfaceController reloadRootControllersWithNames:@[WATCH_INTERFACE_LOADING] contexts:@[context]]; 


     NSDictionary *request = //My Request data; 
     [[WCSession defaultSession] sendMessage:request 
            replyHandler:^(NSDictionary *reply) { 
             //handle reply from iPhone app here 

             NSDictionary *resultDict = [reply objectForKey:WATCH_REQUEST_RESULT]; 
// Use reply from Phone app 
            } 
            errorHandler:^(NSError *error) { 
             //catch any errors here 
// Getting error here 7001 Error. 
            } 
     ]; 

}

由于激活方法是异步的使用是在委托方法类似如下：

public func session(_ session: WCSession, activationDidCompleteWith activationState: WCSessionActivationState, error: Error?){ 
    print("activationDidCompleteWith") 
    if activationState == WCSessionActivationState.activated { 
     NSLog("Activated") 
     if(WCSession.default().isReachable){ 

      do { 
       try session.updateApplicationContext(
        [WatchRequestKey : "updateData"] 
       ) 
      } 
      catch let error as NSError { 
       print("\(error.localizedDescription)") 
      } 
     } 
    } 

    if activationState == WCSessionActivationState.inactive { 
     NSLog("Inactive") 
    } 

    if activationState == WCSessionActivationState.notActivated { 
     NSLog("NotActivated") 
    } 
}
