xcode - 全屏退出后模态 NSWindow 消失

Question

我正在开发 OS X 应用程序，并且是 Swift 和 OS X 开发的新手。我有一个我想成为模式的窗口，有时会有很多内容要显示，所以我想让它进入全屏模式。窗口 nib 和下面的代码实现了这一点，但退出全屏模式会导致窗口消失。如果我转到另一个桌面并返回，窗口又回来了。下面是我的应用委托(delegate)代码。

import Cocoa

class AppDelegate: NSObject, NSApplicationDelegate {
    let theApp: NSApplication = NSApplication.sharedApplication()
    var fooController: FooController?

    func applicationDidFinishLaunching(aNotification: NSNotification?) {
        // Insert code here to initialize your application
    }

    @IBAction func sessionFoo(sender: AnyObject) {
        if fooController == nil {
            fooController = FooController(windowNibName: "FooWindow")
        }

        // This works when it returns from FullScreen but isn't modal
        // fooController!.showWindow(self)

        // This is modal but the window disappears when returning from FullScreen
        theApp.runModalForWindow(fooController!.window)
    }
}

在窗口的属性检查器中:检查以下内容:

   Shadow
   Close
   Resize
   Restorable
   Deferred (for Memory)

一切都是“推断行为”
全屏是“主窗口”，我试过“辅助窗口”，但没有成功。
内存已“缓冲”。

这是基于文档的应用程序的辅助窗口。我错过了什么？谢谢。

1.覆盖 NSWindowDelegate.windowDidExitFullScreen;

2.设置NSWindow.Delegate;

3.在windowDidExitFullScreen中调用NSWindow.makeKeyAndOrderFront或NSWindow.OrderFront；

public class tbWindowDelegate : NSWindowDelegate
{   
    public EventHandler WindowFullScreenDidExit;

    public override void DidExitFullScreen(NSNotification notification)
    {
        if (WindowFullScreenDidExit != null)
            WindowFullScreenDidExit(notification, EventArgs.Empty);
    }
}


public class tbWindow : NSWindow
{       
    protected bool mRunModal = false;
    protected tbWindowDelegate mDelegate = null;

    public tbWindow() : base()
    {
        this.InitEvent();
    }

    private void InitEvent()
    {           
        this.mDelegate = new tbWindowDelegate();
        this.mDelegate.WindowFullScreenDidExit = this.OnWindowFullScreenDidExit;
        this.Delegate = this.mDelegate;
    }


    protected virtual void OnWindowFullScreenDidExit(object sender, EventArgs e)
    {
        if (this.mRunModal)
        {
            //this.MakeKeyAndOrderFront(this);
            this.OrderFront(this);
        }

    }   

}
