In the innermost scanner loop, I am trying to use

NSManagedObject which I then want to populate with the two strings and
the integer using [object setValue:forKey:]
The problem I'm having is the line that tries to store the integer:
[object setValue:i forKey:@"fileIndex"];
I get the compiler error "Passing argument 1 of 'setValue"forKey'
makes pointer from integer without a cast".
Can anyone tell me how to fix this? I'm also wondering if I'm using
the correct methods to accomplish the task.

setValue:forKey takes an id (NSObject*) not an integer. You need to wrap
your integer into an NSNumber, [ NSNumber numberWithInt:i ] and set that.
