In the Foundation framework we have an NSCache class which acts as a Dictionary but also encapsulates a logic of purging its content after reaching the max elements.

I highly recommend the following book.
This is in regards to penetration testing of the applications & the phone but you can use the same knowledge to write secure code for your applications. https://t.co/bNdKXqfdqK
