Я искал способ запуска демонов на iPhone, и я создал небольшое тестовое приложение с Xcode, изучая исходный код приложения муравьев , который научил меня использовать launchctl
Но к сожалению это не работает.
Я установил свое приложение с SSH на свой iPod Touch в /Applications/
, затем я запускаю его с SSH через учетную запись mobile
, и мой журнал говорит следующее:

Когда я запускаю его с root
(делаю это с su
), я запускаю демон, но он ничего не делает.
Мой демон должен отображать UIViewAlert
каждые десять секунд с момента запуска:
