Question

I have a integer named marbles, and am trying to save it into an array using the following code:

[records setValue:marbles forKey:@"marbles"];

With this code, I get the warning:

warning: Semantic Issue: Incompatible integer to pointer conversion sending ‘int’ to parameter of type ‘id’

So, How do I set the value for an NSInteger.

Next Question, How do re-upload the array into core data? I fetch the array, make changes, and how do I apply those changes back to Core Data?

Thanks

Answer 1

Initialize an NSNumber (which is what CoreData is expecting) with your integer:

NSNumber *marbleNumber = [NSNumber numberWithInt:marbles];
[records setObject:marbleNumber forKey@"marbles"];

Or:

[records setMarbles:[NSNumber numberWithInt:marbles]];

To persist your changes, you save your context:

NSError *error;
[myManagedObjectContext save:&error];

//handle your error
