免责声明:不是可用于生产.它可能会被App Store拒绝.如果将来ifconfig的输出发生更改，也会出错. 之所以这样做，是因为我缺乏翻译链接中给出的C代码的技能.它不能替代完整的Swift解决方案.话虽如此，它的工作原理...

DISCLAIMER: this is not production-ready. It would probably be rejected by the App Store. It's also subject to errors if the output of ifconfig changes in the future. I've made this because I lacked the skills to translate the C code given in the links. It does not replace a full Swift solution. That being said, it works...

获取ifconfig的输出并进行解析以获取与接口关联的MAC地址(在此示例中为en0):

Get ifconfig's output and parse it to get the MAC address associated with an interface (en0 in this example):

let theTask = NSTask()
let taskOutput = NSPipe()
theTask.launchPath = "/sbin/ifconfig"
theTask.standardOutput = taskOutput
theTask.standardError = taskOutput
theTask.arguments = ["en0"]

theTask.launch()
theTask.waitUntilExit()

let taskData = taskOutput.fileHandleForReading.readDataToEndOfFile()

if let stringResult = NSString(data: taskData, encoding: NSUTF8StringEncoding) {
    if stringResult != "ifconfig: interface en0 does not exist" {
        let f = stringResult.rangeOfString("ether")
        if f.location != NSNotFound {
            let sub = stringResult.substringFromIndex(f.location + f.length)
            let range = Range(start: advance(sub.startIndex, 1), end: advance(sub.startIndex, 18))
            let result = sub.substringWithRange(range)
            println(result)
        }
    }
}
