Ask HN: How would you do a database connection in an iphone app?

I am trying to develop an iphone application that needs to connect to a database. After about an hour of googleing I found that there a lot of ways to go about doing this(SQLite database locally on the iphone, MYSQL wrapper class to connect to a database, and many other). What is the best method or convention most developers use? Does the iphone SDK have any built in NS objects to connect to a database?
