Hi, I'm not sure if I'm posting in the right section. If it isn't, mods please help to move this thread. Thanks! Anyway, I'm working on a jailbroken phone. And I need to find a way to kill certain processes from my app. I've tried doing: Code: system("usr/bin/killall processName"); But this is not working on the iPhone. It did work on the simulator when I tested it though. I tried popen, but it isn't working either.
