Release memory at Run-time in cocos2d iphone with ARC enabled -


i have enabled arc in cocos2d iphone project. facing 1 problem of elements not visible on-screen or off-screen. want release memory occupied elements @ run time.as have implemented arc in project release memory @ compile time. think should release memory @ run time memory optimization. demonstration have implemented infinite tiled map using 4 tile map object. files shown below.

helloworldlayer.h

#import "cocos2d.h" #import "box2d.h" #import "gles-render.h" #define ptm_ratio 32 @interface helloworldlayer : cclayer {     cctmxtiledmap *map1;     cctmxtiledmap *map2;     cctmxtiledmap *map3;     cctmxtiledmap *map4;     cctmxtiledmap *defaultmap;     float maptobeadded;     int whichmap;     cgsize screensize;     int speed;     bool complexmap;     ccmenu *menu; } +(ccscene *) scene; @end

helloworldlayer.mm

    y = y+speed;     self.position =ccp(self.position.x, y);     menu.position = ccp(menu.position.x, menu.position.y-speed);     printf("%d\n",[[self children] count]); } @end

so know possible release memory @ run-time? should do? kind of or guidance helpful.

under arc release object held strong reference, have nil references it.
