i am iphone developer very new to this field....i am developing a ebook app in iphone using cocos2d...i use more than 150 images(i guess) the problem while turning from one page to another images get hanged randomly......
i tried this also [[TextureMgr sharedTextureMgr] removeAllTextures]; but went in vain...i guess the the problem is with the memory.....this my coding for all the pages
-(id)init
