Swift中的MacOS菜单

灵感来自“您正在寻找的是所谓的NSSplitViewController”

代码如下:

class MenuController: NSViewController {
    override func loadView() {
        super.loadView()
        tabViewController = parent?.childViewControllers[1] as! NSTabViewController! //The parent is the SplitView, so the child in the second view would be the TabViewController
    }
    @IBOutlet weak var FirstButton: NSButton!
    @IBOutlet weak var SecondButton: NSButton!

    var tabViewController = NSTabViewController()

    @IBAction func FirstView(_ sender: Any) {
        tabViewController?.selectedTabViewItemIndex = 0 //Now that the TabViewController is specified, one may set the current view controller within the tabview.
    }

    @IBAction func SecondView(_ sender: Any) {
        tabViewController?.selectedTabViewItemIndex = 1 //Shows the second view in NSTabViewController
    }
}

在图中 NSSplitViewController 有两个 childViewControllers ; 因此,它是这些控制器的父级,可以通过 parent? 方法。一旦指定了 tabViewController ,然后可以设置 selectedTabViewItemIndex[value] 在中切换视图 NSTabViewController .
