如何使用Swift在运行时更改应用程序的行为,就像我在更改应用程序是agent(UIElement)一样?

我正在编码一个Mac应用程序,它是菜单栏右侧的NSPopoverApplication is agent(UIElement)设置为YES)。我允许用户通过单击并向下拖动弹出窗口来分离弹出窗口,这会将应用程序置于窗口内。这很好。但是,当将应用程序从菜单栏拖到窗口中时,我希望我的应用程序图标出现在停靠栏中,并且希望在菜单栏的左侧显示特定于应用程序的菜单,就像Application is agent(UIElement)设置为NO。相反,当关闭窗口并将应用程序返回到菜单栏中的弹出框时,我希望我的应用程序图标从停靠栏中消失,并且不再在菜单栏的左侧显示应用程序专用菜单({{ 1}}重新设置为Application is agent(UIElement))。

根据this question,我知道无法在运行时更改YES。但是,给出的答案是在Objective-C中进行的,自OS X 10.9起,最后一个功能似乎已被淘汰。如何使我的应用具有与在运行时使用Swift更改Application is agent(UIElement)相同的行为?

我知道在Application is agent(UIElement)中显示应用程序图标/菜单栏菜单,而在windowDidBecomeMain中隐藏应用程序图标/菜单栏菜单。

谢谢。

花费了大量的尝试和错误,但是我终于弄明白了。您可以使用Application is agent(UIElement)来代替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中:

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)
        }
    }
}

此外,如果在切换到常规菜单后无法显示菜单和停靠图标,则可能必须执行以下操作。对于较旧的Mac OS版本,这绝对是必需的。

        // needed to activate menu
    NSArray *dockAppA = [NSRunningApplication runningApplicationsWithBundleIdentifier:@"com.apple.loginwindow"];
    NSRunningApplication *dock = [dockAppA firstObject];
    [dock activateWithOptions:NSApplicationActivateIgnoringOtherApps];

    NSArray *dockAppB = [NSRunningApplication runningApplicationsWithBundleIdentifier:@"myAppBundleIdentifier"];
    NSRunningApplication *myApp = [dockAppB firstObject];
    [myApp activateWithOptions:NSApplicationActivateIgnoringOtherApps];
