如何让我的应用程序表现得像我在运行时使用 Swift 更改 Application is agent(UIElement) 一样?

W. *_*ook 2 macos cocoa nspopover swift lsuielement

我正在编写一个NSPopover位于菜单栏右侧的 Mac 应用程序(Application is agent(UIElement)设置为YES)。我允许用户通过单击并向下拖动来分离弹出窗口,这会将应用程序放在窗口内。这工作正常;但是,当应用程序被拖出菜单栏并进入一个窗口时,我希望我的应用程序图标出现在 Dock 中,并在菜单栏的左侧显示特定于应用程序的菜单,就好像Application is agent(UIElement)设置为NO。相反,当窗口关闭并且应用程序返回到菜单栏中的弹出窗口时,我希望我的应用程序图标从 Dock 中消失并且不再在菜单栏的左侧显示特定于应用程序的菜单(Application is agent(UIElement)已设置回到YES)。

这个问题,我明白Application is agent(UIElement)在运行时改变是不可能的。然而,给出的答案是在 Objective-C 中,最后一个函数似乎从 OS X 10.9 开始贬值了。如何使我的应用程序具有与Application is agent(UIElement)使用 Swift 在运行时更改相同的行为?

我知道显示应用windowDidBecomeMain程序图标/菜单栏菜单会发生在windowWillClose.

谢谢。

经过大量的反复试验,但我终于弄明白了。而不是使用Application is agent(UIElement),你使用NSApp.setActivationPolicy。现在这是我的代码。在应用程序委托中:

var isWindow = false

class AppDelegate: NSObject, NSApplicationDelegate, NSPopoverDelegate {

    let statusItem = NSStatusBar.system.statusItem(withLength: NSStatusItem.squareLength)
    let popover = NSPopover()

    func applicationDidFinishLaunching(_ aNotification: Notification) {
        // Insert code here to initialize your application

        NSApp.setActivationPolicy(.accessory)

        if let button = statusItem.button {
            button.image = NSImage(named: "StatusBarImage")
            button.action = #selector(togglePopover(_:))
        }
        popover.contentViewController = MainViewController.loadController()
        popover.delegate = self
        popover.animates = false
        popover.behavior = .transient
    }

    @objc func togglePopover(_ sender: Any?) {
        if popover.isShown == true {
            popover.performClose(sender)
        } else if detachedWindowController.window!.isVisible {
            detachedWindowController.window?.setIsVisible(false)
            isWindow = true
        } else if isWindow == true {
            detachedWindowController.window?.setIsVisible(true)
        } else {
            if let button = statusItem.button {
                popover.show(relativeTo: button.bounds, of: button, preferredEdge: NSRectEdge.minY)
            }
        }
    }

    lazy var detachedWindowController: DetachedWindowController = {
        let detachedWindowController = DetachedWindowController(windowNibName: "DetachedWindowController")
        detachedWindowController.contentViewController = MainViewController.loadController()
        return detachedWindowController
    }()

    func popoverShouldDetach(_ popover: NSPopover) -> Bool {
        return true
    }

    func detachableWindow(for popover: NSPopover) -> NSWindow? {
        return detachedWindowController.window
    }
}

DetachedWindowController

class DetachedWindowController: NSWindowController, NSWindowDelegate {

    @IBOutlet var detachedWindow: NSWindow!

    override func windowDidLoad() {
        super.windowDidLoad()

        detachedWindow.delegate = self
    }

    func windowWillClose(_ notification: Notification) {
        isWindow = false
        NSApp.setActivationPolicy(.accessory)
    }

    func windowDidBecomeMain(_ notification: Notification) {
        if NSApp.activationPolicy() == .accessory {
            NSApp.setActivationPolicy(.regular)
        }
    }
