What is the best way to store (possibly hundreds) of strings in iPhone app?

There is a possibility that a user of my app may enter tens/hundreds/thousands of pieces of information into the app. For example, 开发者_运维知识库they may enter names, addresses, phone numbers of various people.

What would you recommend is the best way to store (a potentially large amount) these strings?

Ideally, I'd like to be able to export the inputted data as a text delimited file or a spreadsheet.

You should consider either CoreData or sqlite. CoreData can be over an xml or sqlite database. If you use sqlite, you should consider the fmdb wrapper on github

But, a lot depends on the access patterns. Sqlite is very fast but it also offers querying capabilities.

Sqlite3 is a great way to store a large amount of data.

Failing that you could always use NSUserDefaults
