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:

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

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

import Cocoa

class MenuController: NSViewController {

    var passedData = ""

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

}
