I am trying to implement a generic resource management singleton class that will load all of the images, sounds, and data files for the app. This resource manager will keep track of how frequently each object is requested (or in the case of sounds when they are played). Then when an applicationDidReceiveMemoryWarning: message was received, the manager would purge from memory the less frequently used items (but ready to load them again if they are requested). I am trying to implement David Duncan's suggestion, but because I am dealing with images and sound, its not clear how much memory is actually being used (although worst case estimates can be made). Thats why I was wondering if there was a generic approach to get either the total app memory used, or get total memory used by a particular object (recursively following pointers of course). _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
