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? Local Data:
Core Data hooked into a sqlite.db is the way to go. Some say it's a little heavy but I have had a lot of luck with it. It's going to give you everything you need to persist and query data locally on the device. Remote Data:
You pretty much have to go with a web service layer. The standard now-a-days is RESTful JSON. Directly connecting to a remote DB is too unreliable for the mobile world. ASIHTTPRequest: A wrapper around network level API's for connecting to web servers. Use this. Depends on the app but generally speaking I would use CoreData to map the object and store it in SQLite database. I can't think of any reason you would use a MySQL wrapper. If I wanted to get something from a MySQL database I would set up a REST api on my server. We use a web service with JSON. On the iPhone, we use HTTPRiot to talk to the web service using JSON.
