Executing shell commands with NSTask – Objective-C Cocoa
You could do something like: NSTask *task = [[NSTask alloc] init]; [task setLaunchPath:@”/bin/bash”]; [task setArguments:@[ @”-c”, @”/usr/bin/killall Dock” ]]; [task launch]; Exactly what launch path and arguments you provide are dictated by the command you want to run and its parameters.
