OpenGl memory management on iOS

I have a UITableView with custom Cells. These cells are containing each an OpenGL drawing (a graph chart). When I scroll the table and the c开发者_StackOverflowells become hidden, the cells begin the process of destroying objects, like GLViewController and GLView. As you know GLView has this method: destroyFramebuffer which clears the allocated buffer for OpenGL drawings. My problem occurs when I try to scroll the table very-very fast. Tell me please is this the problem of the framework, which does not manage to clear buffers or how could I solve this thing??

It's damn bad idea to have multiple GL views in table cells. Each GL view allocates a lot of memory, and destroying GL buffers also tooks some time, what you can see during fast scrolling. You should redesign your application to use only one GL view (for example, make it hidden, build graphs on it, catch image to UIImage, and show only it in table cell).
