iphone - Drawing on a view(in a scroll-view) is consuming too much memory in ipad devices -

I have added a view to a scrollview (maxZoomScale = 1, minZoomScale = 0.25). The close-up of the scene-frame (2000, 2000) is the size I have written the code for drawing a path (for ~ 8000 digits) in Draw Draw. Whenever ScrollView's zooming ends, I had flagged the diagram of the view, now every time it draws to drawRect it has a huge memory (~ 16 MB). Due to the memory warnings, please help any body solve this problem due to this iPad reboot ...

Check the CatLayer You should not depict the 2000x2000 view; Most of the luggage is offscreen.
