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?

我将命令作为字符串命令"，但可以根据需要轻松操作数据.

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

不需要获取返回的输出值.

There is no need to get a returned output value.

推荐答案

NSTask 很容易做到这一点.对于同步调用，您可以使用如下片段:

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 调用确保它在继续之前完成.如果任务可以是异步的，您可以删除该调用并让 NSTask 完成它的工作.

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.
