I've created an Xcode project using the Command Line Tool template
with the Type set to "Core Data".
I defined an Entity with 3 Properties. Two of the Properties are
strings and one is an integer (Int 16).
I fetch data from 3 files read from the internet and use a scanner
which extracts the strings. The integer is an index identifying the
file.
In the innermost scanner loop, I am trying to use
NSEntityDescription
insertNewObjectForEntityForName:inManagedObjectContext, to create an
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.
