Mac Dev Part 1 - Menu Bar

时间总是挤出来的

从今天开始进行记录和学习Mac开发

1.展示名为statusItembutton的图片到Mac的状态栏上(应该是叫状态栏吧)

AppDelegate.swift

    let statusItem = NSStatusBar.system.statusItem(withLength:  NSStatusItem.variableLength)

    func applicationDidFinishLaunching(_ aNotification: Notification) {
        
        if let button = statusItem.button {
        button.image = NSImage(named: "statusItembutton")
        button.action = #selector(showDetail(sender:))
        }
    }

    @objc func showDetail(sender: NSStatusBarButton) {
            print("nice")
    }

效果:

2.工程不希望window和底部应用图标出现

Main.storyboard

取消 Is Initial Controller 就不会出现window

Info.plist加入 Application is agent (UIElement) --- YES 不会出现应用图标

3.添加MenuButton下拉项(先这么叫...)

AppDelegate.swift

    let menu = NSMenu()

    menu.addItem(NSMenuItem(title: "Show Detail", action:   #selector(showDetail(sender:)), keyEquivalent: "G"))
    // 加分割线
    menu.addItem(NSMenuItem.separator())
    menu.addItem(NSMenuItem(title: "Quit", action: Selector("terminate:"),  keyEquivalent: "q"))
        
    statusItem.menu = menu

其中keyEquivalent这个参数是快捷键,但是你必须把MenuButton点开下拉项才能用快捷键(可能有解决方法,之后会研究)

效果:

4.添加MenuButton下弹显示控制器(先这么叫...)

AppDelegate.swift

    let popover = NSPopover()
    
    func applicationDidFinishLaunching(_ aNotification: Notification) {
        
        if let button = statusItem.button {
            button.image = NSImage(named: "statusItembutton")
            button.action = #selector(showDetail(sender:))
        }
        
        popover.contentViewController = DetailViewController.loadFromNib()
    }
    // 下弹控制器
    @objc func showDetail(sender: NSStatusBarButton) {
        if popover.isShown {
            popover.performClose(sender)
        } else {
            if let button = statusItem.button {
                popover.show(relativeTo: button.bounds, of: button, preferredEdge: .minY)
            }
        }
    }

添加弹出控制器,并在sb中拖入控制器设置对应class和sb ID(其实我发现xib应该更方便一点)

DetailViewController.swift

class DetailViewController: NSViewController {
    
    class func loadFromNib() -> DetailViewController {
        let sb = NSStoryboard(name: "Main", bundle: nil)
        return sb.instantiateController(withIdentifier: "DetailViewController") as! DetailViewController
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do view setup here.
    }
    
}

runAPP即可弹出,效果:
