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

NSString *path = @"/path/to/executable";

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.
