快速杀死进程 [英] Kill process in swift

问题描述

我正在尝试制作一个Mac应用程序，该应用程序将自动关闭在OS上运行的指定代码的应用程序.我正在尝试使用killall(例如在Terminal中).每当我尝试运行程序时，都会得到"sysctl:unknown oid'killall'".

I am trying to make a Mac application that will automatically close a code designated application running on the OS. I am trying to use killall (like in Terminal). Whenever I try to run the program, I get, "sysctl: unknown oid 'killall'".

这是我的代码:

let task = Process()
    task.launchPath = "/usr/sbin/sysctl"
    ///usr/sbin/sysctl
    task.arguments = ["killall","iTunes"]
    let pipe = Pipe()
    task.standardOutput = pipe
    task.standardError = pipe
    task.launch()
    task.waitUntilExit()
    let data = pipe.fileHandleForReading.readDataToEndOfFile()
    let output: String = NSString(data: data, encoding: String.Encoding.utf8.rawValue) as! String
    print(output)

提前谢谢！

推荐答案

我建议您先阅读sysctl的man页-它用于获取和设置内核状态.听起来像您想要的东西吗?

I'd suggest you first read the man page for sysctl -- it's used to get and set kernel state. Does that sound like something you want?

killall的路径是/usr/bin/killall，您可以在终端机上找到

The path to killall is /usr/bin/killall, which you can find from Terminal:

> which killall
/usr/bin/killall

这是完整的Swift代码:

Here's the full Swift code:

let pipe = Pipe()

let task = Process()
task.launchPath = "/usr/bin/killall"
task.arguments = ["iTunes"]
task.standardOutput = pipe
task.standardError = pipe
task.launch()
task.waitUntilExit()

let data = pipe.fileHandleForReading.readDataToEndOfFile()
if let output = String(data: data, encoding: .utf8) {
    print(output)
}
