objective c - Measure the memory usage of an UIImage array -


i implementing custom control present images, , control uses array store either uiimage or nsstring object. want implement such kind of mechanism:if memory usage high, control write big uiimage objects files, replace uiimage objects corresponding files path(nsstring objects).

so question how mesure memory usage of uiimage? thanks!

whenever code utilizes memory portion generates problem ios calls - (void)didreceivememorywarning method. conversion part you'll have in method.
