Question

I have an NSArray called namesArray.

I need to store all the names existing in namesArray using coredata.

How do i achieve this ?

Does we need to create any database like 'names.sqlite' using sqlite manager?

Answer 1

No you don’t need to create a names.sqlite using manager. You should go through some of the tutorial found on the net for example: Here or Here.

You basically need to save in the datamodel in valueForKey format.

   //Coredata saving
 self.theAppDel=[[UIApplication sharedApplication] delegate];
 NSManagedObjectContext*context=[self.theAppDel managedObjectContext];
 NSManagedObject*object=[NSEntityDescription insertNewObjectForEntityForName:@"Contacts" inManagedObjectContext:context];
 NSError*error=nil;

 [object setValue:[namesArray objectAtIndex:0] forKey:@"name"]; //for saving first name

1. Creating an instance of your appdelegate .

2. Access your Managed Object Context and Managed Object

3. Assuming you created a entity description with name contacts. With the count of number of items in your array, add each object for a column named name (which i’m assuming you would have created).

This is short example, but you should go through the tutorials and read apple’s documentation.

EDIT: As Ondra mentioned my earlier solution would have added only the last element. Use the following for adding: Adding NSMutableArray in CoreData Thanks Ondra Peterka
