swift - mac app打开后如何执行命令

Question

我想在我的应用打开系统终端应用后执行命令。我使用以下内容打开终端应用程序:

let url = NSURL(fileURLWithPath: "/System/Applications/Utilities/Terminal.app", isDirectory: true) as URL
let configuration = NSWorkspace.OpenConfiguration()
NSWorkspace.shared.openApplication(at: url, configuration: configuration, completionHandler: { app, error in
    //app.executeMyCommand("echo hello")
})

打开后我要执行命令“echo hello”，如completionHandler所示。如何做到这一点？

另一种解决方案:

向终端发送一个 do script Apple 事件:

let terminalScript = "echo hello"
if let url = NSWorkspace.shared.urlForApplication(withBundleIdentifier: "com.apple.Terminal") {
    let configuration = NSWorkspace.OpenConfiguration()
    let doScriptEvent = NSAppleEventDescriptor(eventClass: kAECoreSuite,
        eventID: kAEDoScript, targetDescriptor: nil, returnID: AEReturnID(kAutoGenerateReturnID),
        transactionID: AETransactionID(kAnyTransactionID))
    doScriptEvent.setParam(NSAppleEventDescriptor(string: terminalScript), forKeyword:keyDirectObject)
    configuration.appleEvent = doScriptEvent
    NSWorkspace.shared.openApplication(at: url, configuration: configuration, completionHandler: { app, error in
        if error != nil {
            print("Error: \(String(describing: error))")
        }
    })
}

允许发送 Apple 事件:

• 在“签名和功能”、“强化运行时”下，选中“Apple 事件”
• 在 info.plist 中添加一行 'Privacy - AppleEvents Sending Usage Description'
• 在权利中添加一行“com.apple.security.temporary-exception.apple-events”和项目“com.apple.Terminal”
