What I would probably do is have each cached object check in with a size, and track the total cache size separately. When you get a memory warning, shrink the cache by about half. If the cache is under a certain size (say 5MB) just purge the entire thing. -- David Duncan Apple DTS Animation and Printing _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
