ios - Memory issues (my concerns about my app) -


under arc, know objects deallocated automatically compiler, don't know when happens.

consider object holds various data in it, long nsstrings uiimages , more. i'm using same object in many of controllers, if pass object through many controllers via uinavigationcontroller, still 1 object or copy itself? i'm concerned objects won't deallocated because controllers still on navigation stack. want figure out what's happening @ compiler side.
