Handling lots of objects

First, I am an objective-c newbie. Just thought I would get that out of the way ;)

I am trying to handle objects but I'm a bit confused about the best way to go around doing so. Let me put this into a bit of context:

I have a preference area where a user can add a new Foo to the app. Once the input fields are validated it should spawn a new object of type Foo (according to my Foo class). The user could have anywhere from 1 to 100 of these in the app. What is the best way of keeping track of all of these? How can I create them in the code and keep track of them?

I bet that made no sense, but I have tried to explain it the best I can. Please feel free to ask for more details.

Thanks in advance for any help

It depends somewhat on what you want to do with them. To just keep them in RAM, you can store pointers to those objects in an NSArray (or NSMutableArray), or if you need to be able to find them with a key use an NSDictionary (or NSMutableDictionary). To save them so that they persist even after your app exits so you can load them again next time you can them write them to a file (plist, sqllite, coredata, ...).

Oh, I thought you said lots. :-) I was already planning an explanation on the flyweight pattern when I read 'up to 100'. You can just put these in an array.
