如何获取Dock for Mac OS X编程中当前正在运行和可见的所有应用程序的列表？

Question

我需要知道哪些应用程序正在运行并且有一个活动窗口.类似的东西必须是'command + tab'热键切换器中的内容.

当我运行这样的代码时:

NSWorkspace * ws = [NSWorkspace sharedWorkspace];
NSArray * apps = [ws runningApplications];
NSLog (@"%@", apps);

我在日志中得到这个:

"<NSRunningApplication: 0x6080001052b0 (com.apple.loginwindow - 66)>",
"<NSRunningApplication: 0x608000105340 (com.apple.systemuiserver - 285)>",
"<NSRunningApplication: 0x6080001053d0 (com.apple.dock - 284)>",
"<NSRunningApplication: 0x608000105460 (com.apple.finder - 286)>",
"<NSRunningApplication: 0x6080001054f0 (com.apple.iTunesHelper - 339)>",
"<NSRunningApplication: 0x608000105580 (cc.omh.Clyppan - 340)>",
"<NSRunningApplication: 0x608000105610 (ws.agile.1PasswordAgent - 333)>",
"<NSRunningApplication: 0x6080001056a0 (com.irradiatedsoftware.Cinch-Direct - 342)>",
"<NSRunningApplication: 0x608000105730 (com.leapmotion.Leap-Motion - 343)>",
"<NSRunningApplication: 0x6080001057c0 (com.apple.notificationcenterui - 316)>",
"<NSRunningApplication: 0x608000105850 (com.smileonmymac.textexpander - 348)>",
"<NSRunningApplication: 0x6080001058e0 (com.lightheadsw.caffeine - 350)>",
"<NSRunningApplication: 0x608000105970 (2BUA8C4S2C.com.agilebits.onepassword4-helper - 309)>"

它显示了所有正在运行的应用程序.我只想要在Dock中运行和可见的应用程序.

Answer 1

返回的数组的成员[NSWorkspace runningApplications]是类型NSRunningApplication.你想挑选出activationPolicy属性类型的那些NSApplicationActivationPolicyRegular.

Answer 2

以下代码使用NSWorkplace workspace.runningApplications.filter调用来提取应用程序。

// Swift 4.1
//: Playground - noun: a place where people can play

import Cocoa

let workspace = NSWorkspace.shared
let apps = workspace.runningApplications.filter{  $0.activationPolicy == .regular }

Answer 3

针对Swift 3进行了更新

    let ws = NSWorkspace.shared()
    let apps = ws.runningApplications
    for currentApp in apps
    {
        if(currentApp.activationPolicy == .regular){
            print(currentApp.localizedName!)
        }
    }

Answer 4

要访问所有正在运行的应用程序的列表，请使用runningApplications中的方法NSWorkspace。
