iOS simulator stop caching image in memory cache

steps to reproduce simulate memory warning > reload image > check in memory cache (found nil)

image is cached in disk but not in memory after memory warning which cause flicker on reload

This is the expected behavior, the memory cache is used temporarily when there are resources available. If your UI is flickering, it would be probably because of other reasons, like loading big images in a list without downsizing it.
