swift - 将按钮添加到 NSTouchBar 控制条

Question

我正在做一个宠物项目，它在触摸栏上显示当前的加密货币价格。我是一名网络开发人员，但不是 Swift 开发人员，所以进展缓慢。

现在，基本功能已经到位，但当然只有在应用程序窗口处于活动状态时才会显示数据。无论哪个应用程序处于活动状态，我都希望能够查看数据，而我能看到的唯一方法是将一个按钮添加到触控栏的控制条部分。

如何将按钮添加到控制条？对此没有公共 API，但我可以看到其他非 Apple 应用程序可以做到这一点。

仅通过私有API，您需要连接/System/Library/PrivateFrameworks/DFRFoundation.framework

桥：

// TouchBarPrivateApi-Bridging.h
#import "TouchBarPrivateApi.h"`

标题：

// TouchBarPrivateApi.
#import <AppKit/AppKit.h>`
extern void DFRElementSetControlStripPresenceForIdentifier(NSTouchBarItemIdentifier, BOOL);
    extern void DFRSystemModalShowsCloseBoxWhenFrontMost(BOOL);

    @interface NSTouchBarItem (PrivateMethods)
    + (void)addSystemTrayItem:(NSTouchBarItem *)item;
    + (void)removeSystemTrayItem:(NSTouchBarItem *)item;
    @end


    @interface NSTouchBar (PrivateMethods)
    + (void)presentSystemModalFunctionBar:(NSTouchBar *)touchBar placement:(long long)placement systemTrayItemIdentifier:(NSTouchBarItemIdentifier)identifier;
    + (void)presentSystemModalFunctionBar:(NSTouchBar *)touchBar systemTrayItemIdentifier:(NSTouchBarItemIdentifier)identifier;
    + (void)dismissSystemModalFunctionBar:(NSTouchBar *)touchBar;
    + (void)minimizeSystemModalFunctionBar:(NSTouchBar *)touchBar;
    @end

并使用它：

// AppDelegate applicationDidFinishLaunching
func applicationDidFinishLaunching(_ aNotification: Notification) {
    TouchBarController.shared.setupControlStripPresence()
}

// TouchBarController class TouchBarController: NSObject, NSTouchBarDelegate {

    static let shared = TouchBarController()

    let touchBar = NSTouchBar() func setupControlStripPresence() {
        DFRSystemModalShowsCloseBoxWhenFrontMost(false)
        let item = NSCustomTouchBarItem(identifier: .controlStripItem)
        item.view = NSButton(image: #imageLiteral(resourceName: "Strip"), target: self, action: #selector(presentTouchBar))
        NSTouchBarItem.addSystemTrayItem(item)
        DFRElementSetControlStripPresenceForIdentifier(.controlStripItem, true)
    }

更新 10.14

+ (void)presentSystemModalTouchBar:(NSTouchBar *)touchBar placement:(long long)placement systemTrayItemIdentifier:(NSTouchBarItemIdentifier)identifier;
+ (void)presentSystemModalTouchBar:(NSTouchBar *)touchBar systemTrayItemIdentifier:(NSTouchBarItemIdentifier)identifier;
+ (void)dismissSystemModalTouchBar:(NSTouchBar *)touchBar;
+ (void)minimizeSystemModalTouchBar:(NSTouchBar *)touchBar;
