Core data/Database IOS

Question

I'm new to IOS programming, and I have had a great time learning it. It took me about 4 months to really get a good grasp on it. I have began creating my own app, and I ran in to a few questions. The app I'm creating is a live app like instagram, foursquare, etc. How do I store all of the information I need. Can I use Core-Data to create a real-time app that can handle updates from multiple users?

The app I'm creating is a live app like instagram, foursquare, etc. How do I store all of the information I need.

You'll probably create some sort of server to manage the data. Having a single, central source of data is a lot easier than trying to sync data between multiple devices.

Can I use Core-Data to create a real-time app that can handle updates from multiple users?

You can -- Core Data works on MacOS X as well as on iOS, so you could write a Mac program that is the server for your iOS app. Whether that's the best approach is another question... I suppose it depends on how well you already know Core Data, whether there are any advantages to using the same Core Data data model on both the server and the client, how many clients you think you might have to support at once, etc.

If you're asking about using Core Data on the iOS client, then yes, you can certainly do that.
