actually
i have this image
sheet = [CCSpriteSheet spriteSheetWithFile:@"backTile.png" ];
[self addChild:sheet z:10];
sprite = [sheet createSpriteWithRect:CGRectMake(16,16,16,16)];//32 * idx,32 * idy,32,32 make 32 all to color box
[sheet addChild:sprite ];
however if i use this [super removeAllChildrenWithCleanup:NO];
now i want to remove them so i did
[sheet removeChild:sprite cleanup:YES];
But its not working

how ever if i use this
[super removeAllChildrenWithCleanup:NO];
then everything gets clear on the screen
