允许在macCatalyst中对Touch Bar进行用户自定义
问题描述 投票：1回答：1
在催化剂Swift项目中，UIViewController子类创建了一个TouchBar，如下所示：
override func makeTouchBar() -> NSTouchBar? {
let touchBar = NSTouchBar()
touchBar.delegate = self
touchBar.defaultItemIdentifiers = [<<some>>]
touchBar.customizationAllowedItemIdentifiers = [<<more>>]
touchBar.customizationIdentifier = "com.me.myapp.touchbar"
return touchBar
}
默认项目显示在TouchBar上，但是没有菜单项可以自定义它们。读取the TouchBar documentation有两个选项：
1：NSApplication
自定义菜单项当特定的NSTouchBar对象在触摸栏中可见时，用户可以通过选择栏自定义菜单项来为其调用自定义UI。要启用此菜单项，您必须明确选择加入，您可以通过以下方式进行选择：
- [如果您希望系统在应用程序菜单中自动命名，放置，验证和激活此菜单项，请将应用程序对象（NSApplication类型）的isAutomaticCustomizeTouchBarMenuItemEnabled属性设置为true。
- 要明确地将自定义菜单项放置在应用程序的菜单之一中，请使用应用程序对象的toggleTouchBarCustomizationPalette（_ :)方法。当您执行此操作时，系统仍会命名并验证菜单项，并将其隐藏在没有触摸栏的系统上。
尝试执行任何一个操作都会产生'NSApplication' is unavailable in Mac Catalyst错误。因此，经过一番谷歌搜索后，我发现了这一点：
NSClassFromString("NSApplication")?.setValue(true, forKeyPath: "sharedApplication.automaticCustomizeTouchBarMenuItemEnabled")
print(NSClassFromString("NSApplication")?.value(forKeyPath: "sharedApplication.isAutomaticCustomizeTouchBarMenuItemEnabled"))
此编译并执行得很好。它甚至会打印出之前有Optional(1)的Optional(0)。但是菜单项仍然不存在。我在生成TouchBar，生成菜单和func application(_, didFinishLaunchingWithOptions)时尝试了此操作，但无济于事。
我无法获得第二个，不会给我一个错误。
2：触摸栏
奇怪的是，NSTouchBar具有the same property，但正在运行
NSTouchBar.isAutomaticCustomizeTouchBarMenuItemEnabled = true
在任何时候（也可以编译）没有任何区别。
问题
这是缺少的功能还是有实现该功能的方法。如果是这样：如何？
编辑
我正在自定义菜单栏。由于错误，为两个选项设置相同的快捷方式会在Xcode中导致以下输出：

但是自定义TouchBar操作出现在菜单中（我所有的自定义按钮都消失了，❗MISSING LABEL❗问题很容易解决。
因此，我想知道是否是我的菜单自定义代码引起了该错误，但是在AppDelegate中取消对整个override func buildMenu(with builder: UIMenuBuilder)的注释不会导致自定义菜单出现-仅快捷方式冲突会出现。

在我的Swift Catalyst应用程序（macOS 10.15.3，Xcode 11.3.1）中，我可以打电话
NSTouchBar.isAutomaticCustomizeTouchBarMenuItemEnabled = true
在我的override func makeTouchBar()方法中，“自定义触摸栏...”菜单项出现在“查看”菜单选项卡中。对于缺少的标签，以下工作：
func touchBar(_ touchBar: NSTouchBar, makeItemForIdentifier identifier: NSTouchBarItem.Identifier) -> NSTouchBarItem? {
if identifier == yourIdentifier {
let item = NSPickerTouchBarItem(...)
item.customizationLabel = "View Segmented Control"
return item
}
return nil
}
