如何在objective-c中调用linux命令

Answer 1

void runls()
{
[[NSTask launchedTaskWithLaunchPath:@"/bin/ls"
arguments:[NSArray array]] waitUntilExit];
}

如果你希望调用系统命令，先执行shell：

void runSystemCommand(NSString *cmd)
{
[[NSTask launchedTaskWithLaunchPath:@"/bin/sh"
arguments:[NSArray arrayWithObjects:@"-c", cmd, nil]]
waitUntilExit];
