Question

我有一个NSPopover窗口，我想添加触摸栏支持。我已经设法为标准NSWindow实现了触摸栏支持，但是按照弹出窗口的相同步骤不会导致xCode touchbar模拟器中出现任何触摸栏项目。

我正在makeTouchbar中实施NSTouchBarDelegate和NSViewController，其中NSPopover显示为makeTouchBar。 NSPopover正在调用委托函数，但触摸栏中没有显示任何内容（在下面的代码块中，Touchbar和提示都在记录）。

我担心NSPopover窗口不会触发触摸栏作为活动应用程序，即使它具有键盘焦点。如何显示//MARK: Touch bar @available(OSX 10.12.1, *) override func makeTouchBar() -> NSTouchBar? { Swift.print("Touchbar.") let touchBar = NSTouchBar() touchBar.delegate = self touchBar.customizationIdentifier = .touchBar touchBar.defaultItemIdentifiers = [.tbHint, .colourC] return touchBar } @available(OSX 10.12.1, *) extension RememberViewController: NSTouchBarDelegate { func touchBar(_ touchBar: NSTouchBar, makeItemForIdentifier identifier: NSTouchBarItemIdentifier) -> NSTouchBarItem? { switch identifier{ case NSTouchBarItemIdentifier .tbHint: Swift.print("hint") let buttonView = NSCustomTouchBarItem(identifier: identifier) let button = NSButton(title: "Hint", target: self, action: #selector(showHint)) buttonView.view = button return buttonView case NSTouchBarItemIdentifier .colourC: let colorPicker: NSColorPickerTouchBarItem colorPicker = NSColorPickerTouchBarItem.colorPicker(withIdentifier: identifier) colorPicker.customizationLabel = "Color Picker" colorPicker.target = self colorPicker.action = #selector(showHint) return colorPicker default: return nil } } }窗口的触摸栏项？

import re

print re.findall(r'uid=(.*?),',s)[0]
# prints user1

查看Apple的NSTouchBar Catalog Sample。最新版本有一个确切用例的例子。它被称为背景窗口（您必须通过构建应用中的 Window 菜单显示它。）

他们正在故事板中加载带有NSPopover segue的BackgroundImagesViewController并创建NSTouchBar，如下所示：

@available(OSX 10.12.2, *)
class BackgroundImagesViewController: NSViewController {
  override func makeTouchBar() -> NSTouchBar? {
    let touchBar = NSTouchBar()
    touchBar.delegate = self
    touchBar.customizationIdentifier = .scrubberBar
    touchBar.defaultItemIdentifiers = [.imageScrubber]
    touchBar.customizationAllowedItemIdentifiers = [.imageScrubber]
    touchBar.principalItemIdentifier = .imageScrubber

    return touchBar
  }
}

最好的办法是查看Apple的示例文件。

我尝试测试。我覆盖了NSPopover和NSViewController的makeTouchBar方法，当它弹出时，它不会调用该方法。但是，当我在其上添加TextField时，它将获得键盘的焦点，并且神奇地调用了makeTouchBar方法。触摸栏只显示键盘图标。因此，我认为我可以覆盖NSTextField的makeTouchBar方法，但是失败了。我用Google搜索，他们推荐使用NSTextView，而我将其覆盖了，就可以了！

但是实际上似乎在欺骗系统。

Controllers

呼叫代码：

@IBAction func addAction(_ sender: Any) {
    let addingController = NSStoryboard(name: NSStoryboard.Name("Main"), bundle: nil).instantiateController(withIdentifier: NSStoryboard.SceneIdentifier("controller_adding")) as! AddViewController
    let popover = NSPopover()
    popover.contentViewController = addingController
    popover.behavior = .semitransient

    popover.show(relativeTo: addButton.frame, of: addButton, preferredEdge: NSRectEdge.maxY)
}

这是弹出窗口的ViewController

import Cocoa

class AddViewController: NSViewController {


    @IBAction func OKAction(_ sender: Any) {
        print("OK")
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do view setup here.
        let touch = MyTextView()
        touch.setController(self)
        view.addSubview(touch)  
    }
}

这是重写的NSTextView。

class MyTextView : NSTextView
{

    var controller : AddViewController?

    func setController(_ controller : AddViewController)
    {
        self.controller = controller
    }

    @objc func action()
    {
        controller?.OKAction(self)
    }

    override func makeTouchBar() -> NSTouchBar? {

        let touchbar = NSTouchBar()
        let item_add = NSTouchBarItem.Identifier("item_add")
        touchbar.customizationIdentifier = NSTouchBar.CustomizationIdentifier("add")

        touchbar.customizationAllowedItemIdentifiers = [item_add]
        touchbar.defaultItemIdentifiers = [item_add]

        touchbar.delegate = self

        return touchbar
    }

    override func touchBar(_ touchBar: NSTouchBar, makeItemForIdentifier identifier: NSTouchBarItem.Identifier) -> NSTouchBarItem? {
        let item = NSCustomTouchBarItem(identifier: identifier)
        let item_add = NSTouchBarItem.Identifier("item_add")
        var itemDescription = ""
        switch identifier {
        case item_add:
            itemDescription = "Add Button"
            item.view = NSButton(image: NSImage(named: NSImage.Name("NSTrashEmpty"))!, target: self, action: #selector(action))
        default:
            print("???")
        }

        item.customizationLabel = itemDescription
        return item
    }
}

我不熟悉macOS的开发，也不知道如何关注popover，因此我使用这种方法来实现此功能。
