I am making an IOS app with SimpleDB entries that will expire after 30 days. I currently know how to write, read, and delete from SimpleDB, but I have no idea how to make items automatically expire after X amount of time.
I have read about HMAC-SHA signatures with SimpleDB here (It says they can be used to provide an expiration date) and I found this post saying that one could use CommonCrypto to use HMAC-SHA signatures with AWS (SimpleDB, etc.) on IOS.
My Questions before I proceed: Will that do what I want it to and are there any other ways to make items expire after X amount of time with AWS on IOS?
EDIT: I just found this. If anybody has anything to add, that would be greatly appreciated.
Thank you.
