I'm an absolute newbie on iOS Development at the minute so please pardon me if this seems like such a simple question to ask.
I want to build a project - almost like a note taking application - in which the user will be able to associate tags to their inputs. I'm sure many have seen them before - it's used in things like hashtags, or to give an example of an iOS app - Journalling apps like DayOne have it. It's basically used to generate tags for easy retrieval of a particular article.
My question is - how do you go about creating these kinds of tags? Particularly - how do you implement the tagging system that can generate custom tags for articles in the app?
Is it something that is built into Cocoa/SDK or do i have to look at something more complex like Core Data (NSPredicates) to learn how to create something like that?
OR is it something that has to be done programatically rather than a built in system in SDK?
Thanks.
