    You can’t prevent memory warnings — they’re part of the way the system works. When it needs more memory, it sends warnings to the various running apps to get them to release memory that they don’t need.

    To prevent your drawings from being erased, you need to write them into one or more files so that you can restore them at a later point. You can then safely release the drawings when you get a warning, and read them back as you need them.
