Cocoa / Objective-C Shell命令行执行 [英] Cocoa/ Objective-C Shell Command Line Execution

问题描述

这可能是一个愚蠢的问题，但是如何从我的Cocoa应用程序执行shell命令？

This is probably a stupid question, but how can I execute a shell command from my Cocoa app?

我有一个命令作为字符串命令可以根据需要轻松处理数据。

I have the command as a string "command", but can easily manipulate data as needed.

无需获取返回的输出值。

There is no need to get a returned output value.

推荐答案

NSTask 很漂亮容易做到这一点。对于同步调用，您可以使用类似以下片段：

NSTask is pretty easy to do this with. For a synchronous call, you can use something like this fragment:

NSString *path = @"/path/to/executable";
NSArray *args = [NSArray arrayWithObjects:..., nil];
[[NSTask launchedTaskWithLaunchPath:path arguments:args] waitUntilExit];

-waitUntilExit 调用确保完成然后继续。如果任务可以是异步的，你可以删除该调用，并让NSTask做它的事情。

The -waitUntilExit call makes sure it finishes before proceeding. If the task can be asynchronous, you can remove that call and just let the NSTask do it's thing.
