Mac 开发学习笔记

先说说百度云同步盘的 UI设计 先从 UI 开始

1. Mac如何开启后台应用(就是在 dock 那个地方 启动应用的时候不显示)?

   点击工程的 Target 设置 Info:
   Application is background only == YES

2. 在 Mac 状态栏右上角显示的叫做NSStatusItem

   代码块

    let statusItem: NSStatusItem = NSStatusBar.systemStatusBar().statusItemWithLength(NSSquareStatusItemLength)
    let mainMenu: NSMenu = NSMenu()
    
    let item1 = NSMenuItem(title: "测试1", action: "test1:", keyEquivalent: "")
    let item2 = NSMenuItem(title: "测试2", action: "test2", keyEquivalent: "")
    let item3 = NSMenuItem(title: "测试3", action: "test3", keyEquivalent: "")
    let item4 = NSMenuItem(title: "测试4", action: "test4", keyEquivalent: "")
    let item5 = NSMenuItem(title: "测试5", action: "test5", keyEquivalent: "")

    

    func applicationDidFinishLaunching(aNotification: NSNotification) {
        
        mainMenu.delegate = self
        mainMenu.addItem(item1)
        mainMenu.addItem(item2)
        mainMenu.addItem(item3)
        mainMenu.addItem(item4)
        mainMenu.addItem(item5)
        
        statusItem.button?.image = NSImage(named: "status-syncfinished-lep")
        statusItem.menu = mainMenu
        mainMenu.autoenablesItems = true
    }

    func applicationWillTerminate(aNotification: NSNotification) {
        // Insert code here to tear down your application
    }


    
    func test1(sender: NSStatusBarButton) {
        print(__FUNCTION__)
    }
    
    func test2() {
        print(__FUNCTION__)
    }
    func test3() {
        print(__FUNCTION__)
    }
    
    func test4() {
        print(__FUNCTION__)
    }
    
    func test5() {
        print(__FUNCTION__)
    }
    
    
    // MARK: NSMenuDelegate
    
    func menuWillOpen(menu: NSMenu) {
        if menu == mainMenu {
            print(__FUNCTION__)
        }
    }
    ```
