OSX开发之守护进程（appserver）

1.状态栏程序制作

• xcode创建项目

• 删除Main.storyboard 中的Window和ViewController

• appdelegate 添加代码

import Cocoa
@NSApplicationMain
class AppDelegate: NSObject, NSApplicationDelegate {

    let statusItem = NSStatusBar.system().statusItem(withLength: NSVariableStatusItemLength)
    var statusMenu: NSMenu!

    func applicationDidFinishLaunching(_ aNotification: Notification) {
        statusMenu = NSMenu(title: "")
        let item0 = NSMenuItem(title: "启动App", action: #selector(startApp), keyEquivalent: "")
        item0.isEnabled = true
        statusMenu.insertItem(item0, at: 0)
        
        let item1 = NSMenuItem(title: "设置", action: #selector(setting), keyEquivalent: "")
        item1.isEnabled = true
        statusMenu.insertItem(item1, at: 1)
        
        let item2 = NSMenuItem(title: "退出", action: #selector(exit), keyEquivalent: "")
        item2.isEnabled = true
        statusMenu.insertItem(item2, at: 2)
        
        let icon = NSImage(named: "icon1")
        statusItem.image = icon
        statusItem.menu = statusMenu
    }
    
    func setting() {}
    
    func exit() {
        NSApplication.shared().terminate(self)
    }
    
    func startApp()  {}
}

• info.plist添加 Application is agent (UIElement) 为 true （隐藏dock图标）

2.主程序target添加

• 添加target

• Build Phases 添加copy Files选项，添加target app

• 启动app

let path = Bundle.main.bundlePath.appending("/Contents/SharedSupport/MainApp.app")
let task = Process()
task.launchPath = "/usr/bin/open"
task.arguments = [path]
task.launch()

3.进程间的通讯

• 使用CFMessagePort
• 参考
  • iOS--CFMessagePort实现进程间通信

4.开机启启动

• 参考

  • 三种方式配置Mac OS X的启动项
  • Creating Launch Daemons and Agents
  • 在Mac OS X下，怎样才可以在开关机时自动运行脚本程序？
  • Mac OS X启动项详解

• 使用Launchd

  • 配置plist
  • 添加command Line Tool 并配置启动
  • copy plist文件至 /Library/LaunchAgents 目录下，copy command Line Tool 至 /Users/Shared

• 把启动项添加到用户登录项的脚本

#把文本编辑.app 添加到用户登录项
#!/bin/bash 
/usr/bin/osascript -e "tell application \"System Events\" to make new login item with properties { path: \"/Applications/TextEdit.app\", hidden:false } at end"
