ios - 从iPhone的Watch触发搜寻

Question

是否可以通过Watch代码在iPhone应用程序中触发segue？我一直在研究OS2，它说在两个应用程序都处于 Activity 状态时可以传输数据，但想知道是否可以从Watch代码中调用iPhone应用程序中的代码。

您不能将segue从WatchApp(子应用程序)推送到iPhone App(父应用程序)，但可以肯定地将数据从WatchApp发送到iPhone，并根据该数据可以在iPhone Application上执行segue。

要将更新从Apple Watch发送到iPhone App，您必须在openParentApplication中实现WatchKit Extension。

class func openParentApplication(userInfo: [NSObject : AnyObject], reply: (([NSObject : AnyObject], NSError?) -> Void)?) -> Bool

创建NSDictionary并使用以下代码传递该数据:

func updateInformationToParentApp(emergencyInfo : [NSObject : AnyObject]!){
  // Call the parent application from Apple Watch
  WKInterfaceController.openParentApplication(emergencyInfo) { (returnUpdate, error) -> Void in
    if((error) == nil){
      print("Data send successfully");
    } else {
      print("Error : \(error?.localizedDescription)");
    }
  }
}

在AppDelegate中实现以下方法以处理WatchApp更新。

func application(application: UIApplication, handleWatchKitExtensionRequest userInfo: [NSObject : AnyObject]?, reply: ([NSObject : AnyObject]?) -> Void){
  NSLog("Handler Apple Watch Event ");
  watchEvent(userInfo, reply: reply);
}

func watchEvent(userInfo: [NSObject : AnyObject]!, reply: (([NSObject : AnyObject]!) ->Void)!) {
  let dic = userInfo as NSDictionary;
  NSLog("dic %@", dic);

  // retrieved parameters from Apple Watch
  print(userInfo["Key"])
  //Perform Segue from Here according to Dictionary Info        
  //Pass back values to Apple Watch
  var returnUpdate = Dictionary<String,AnyObject>()
  let watchAppMessage = "Meesage Back To Apple Watch" as NSString;
  returnUpdate["message"] = NSKeyedArchiver.archivedDataWithRootObject(watchAppMessage);
  reply(returnUpdate)   
}
