将数据从NSViewController传递到NSSplitViewController中的另一个NSViewController? [英] Pass data from NSViewController to another NSViewController which is in NSSplitViewController?

问题描述

您好，我无法将数据发送到NSSplitViewController.似乎在IOS开发中无法正常工作.

Hello i've got problems to send data to NSSplitViewController. It doesn't seems work like in IOS development.

firstController:

firstController:

class LoginController: NSViewController {
 //.....
  @IBAction func Login(_ sender: Any) {
     //....
     let story = NSStoryboard(name: NSStoryboard.Name(rawValue: "Main"), 
                bundle: nil).instantiateController(withIdentifier: 
                NSStoryboard.SceneIdentifier(rawValue: "SPLIT")) as! 
                NSSplitViewController
      let vc : ContainerController = ContainerController();
      vc.passedData = "karosas";
      self.view.window?.contentViewController = story;
     //....
   }
 //.....
}

第二个NSSplitViewController:

second NSSplitViewController :

import Cocoa

class ContainerController: NSSplitViewController {

    var passedData = "";

    override func viewDidLoad() {
        super.viewDidLoad()
        print(passedData);
        print("nzn");
    }

}

现在我正在尝试将数据发送到NSViewSplitController.我需要将数据传递到NSSplitViewController中的NSViewController.我确实尝试了许多不同的方法，但是我失败了.所以我认为我需要先将数据传递给SplitController，然后再传递给ViewController.但是我什至不能发送任何数据到NSSplitViewController.有人可以帮我吗?

Now i'm trying to send data to NSViewSplitController. I need to pass data to NSViewController which is in NSSplitViewController. I did try many different ways, but i failed. So i thought that i need to pass data first to SplitController and then to ViewController. But i can't even send any data to NSSplitViewController. Can someone help me?

推荐答案

如果LoginController和MenuController都在ContainerController中，则可以执行以下操作:

If the LoginController and the MenuController are both in the ContainerController, you could do something like:

LoginController

LoginController

import Cocoa

class LoginController: NSViewController {
 //.....
  @IBAction func Login(_ sender: Any) {
     //....
     self.userName = value["name"] as! String
     let MenuVC = parent?.childViewControllers[1] as! MenuController // 0 or 1 depending on order in SplitView
      MenuVC.passedData = self.username
      self.view.window?.contentViewController = parent as! ContainerController
     //....
   }
 //.....
}

MenuController

MenuController

import Cocoa

class MenuController: NSViewController {

    var passedData = ""

    override func viewDidLoad() {
        super.viewDidLoad()
        print(passedData)
        print("nzn")
    }

}
