In-memory cache for saving strings or NSNumbers

Question

Is there any external library out there that does in-memory caching? I was just thinking of creating a NSDictionary with key-value stores for this if there isn't any. I know there's EGOCache but this does disk caching. Any ideas?

Answer 1

NSCache基本上就像一个NSDictionary，只需要做一些修改就可以根据优先级等清除数据。
