store data

[thehindutimes]

How do you save data in your app so it stays there after the app has been shut off.

i.e. I want the user to enter some information the first time they open the app and then keep that information stored.

Is there any good tutorial on this?
or is it too easy to even make a tutorial about?

Cheers!

NSUserDefault is the keyword u r looking for.

It keeps user data in most apps! Check it out!

User defaults can only store objects that conform to NSCoding protocol (meaning they can be archived to NSData).

The answer to your question really depends on the type and the amount of data to be stored.

baja_yu is right.
I assumed from what u said that u wanted to store info like username,email,birthday etc.

In those cases NSUserDefault will fit your purpose depending on the amount of data ofcourse.

Yes, I only need to store username, email and such once.

[thehindutimes]

Can you use NSUserDefault to store data and then load that data into an email?

[baja_yu]

Yes, you can save and load at any time. If you're using MFMailComposer, you need to load it before you present the controller so you can populate it's fields.
