应用程序窗口 退后[隐藏]了后,应用程序图标在 Dock 是 残疾人(后设置 NSApplication.ActivationPolicy.accessory)。你需要启动“任务控制”来显示应用程序窗口。
为了解决上述问题,我做了一个扩展:
import AppKit
extension NSApplication {
public enum Dock {
}
}
extension NSApplication.Dock {
public enum MenuBarVisibiityRefreshMenthod: Int {
case viaMenuVisibilityToggle, viaSystemAppActivation
}
public static func refreshMenuBarVisibiity(method: MenuBarVisibiityRefreshMenthod) {
switch method {
case .viaMenuVisibilityToggle:
DispatchQueue.main.async { // Async call not reaaly needed. But intuition tells to leave it.
// See: cocoa - Hiding the dock icon without hiding the menu bar - Stack Overflow: https://stackoverflow.com/questions/23313571/hiding-the-dock-icon-without-hiding-the-menu-bar
NSMenu.setMenuBarVisible(false)
DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) { // Without delay windows were not always been brought to front.
NSMenu.setMenuBarVisible(true)
NSRunningApplication.current.activate(options: [.activateAllWindows, .activateIgnoringOtherApps])
}
}
case .viaSystemAppActivation:
DispatchQueue.main.async { // Async call not reaaly needed. But intuition tells to leave it.
if let dockApp = NSRunningApplication.runningApplications(withBundleIdentifier: "com.apple.dock").first {
dockApp.activate(options: [])
} else if let finderApp = NSRunningApplication.runningApplications(withBundleIdentifier: "com.apple.finder").first {
finderApp.activate(options: [])
} else {
assertionFailure("Neither Dock.app not Finder.app is found in system.")
}
DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) { // Without delay windows were not always been brought to front.
NSRunningApplication.current.activate(options: [.activateAllWindows, .activateIgnoringOtherApps])
}
}
}
}
public enum AppIconDockVisibilityUpdateMethod: Int {
case carbon, appKit
}
@discardableResult
public static func setAppIconVisibleInDock(_ shouldShow: Bool, method: AppIconDockVisibilityUpdateMethod = .appKit) -> Bool {
switch method {
case .appKit:
return toggleDockIconViaAppKit(shouldShow: shouldShow)
case .carbon:
return toggleDockIconViaCarbon(shouldShow: shouldShow)
}
}
private static func toggleDockIconViaCarbon(shouldShow state: Bool) -> Bool {
// Get transform state.
let transformState: ProcessApplicationTransformState
if state {
transformState = ProcessApplicationTransformState(kProcessTransformToForegroundApplication)
} else {
transformState = ProcessApplicationTransformState(kProcessTransformToUIElementApplication)
}
// Show / hide dock icon.
var psn = ProcessSerialNumber(highLongOfPSN: 0, lowLongOfPSN: UInt32(kCurrentProcess))
let transformStatus: OSStatus = TransformProcessType(&psn, transformState)
return transformStatus == 0
}
private static func toggleDockIconViaAppKit(shouldShow state: Bool) -> Bool {
let newPolicy: NSApplication.ActivationPolicy = state ? .regular : .accessory
let result = NSApplication.shared.setActivationPolicy(newPolicy)
return result
}
}
用法:
前提条件: Info.plist设置 LSUIElement不存在或设置为值 NO。
private func hideDock() {
log.debug("Will hide app from dock.")
let status = NSApplication.Dock.setAppIconVisibleInDock(false)
log.debug("Status is: \(status)")
NSApplication.Dock.refreshMenuBarVisibiity(method: .viaMenuVisibilityToggle)
}
private func showDock() {
log.debug("Will show app in dock.")
let status = NSApplication.Dock.setAppIconVisibleInDock(true)
log.debug("Status is: \(status)")
// The method `viaMenuVisibilityToggle` not working. Menu itens non-clickable
NSApplication.Dock.refreshMenuBarVisibiity(method: .viaSystemAppActivation)
}
