Question

In core data I’ve setup a simple entity called GolferEntity that contains simply a golferObject (transformable type) and playerId (string).

- (void)addOrUpdateGolfer:(GolferObject *)feedObj
{   
    NSLog(@"In add or update Feed");

// get reference to local (stored) golfer item, create it if needed
Golfer *localGolfer = [self golferForId:[feedObj PlayerId]];
if (localGolfer == nil) {
    localGolfer = (Golfer *)[NSEntityDescription insertNewObjectForEntityForName:@"GolferEntity" inManagedObjectContext:[self managedObjectContext]];
    [localGolfer setPlayerId:[feedObj PlayerId]];
}

// set folder fields
[localGolfer setGolferObj:feedObj];

// apply update
NSError *error;
if (![managedObjectContext save:&error]) {
    NSLog(@"%@", [error localizedDescription]);
    //      return nil;
}
NSLog(@"successfully saved user: %@", [feedObj PlayerId]);
//return localFolder;
}

The code is giving me a runtime error which reads:
* -[NSKeyedArchiver dealloc]: warning: NSKeyedArchiver deallocated without having had -finishEncoding called on it.
* Terminating app due to uncaught exception ‘NSInvalidArgumentException’, reason: ‘-[GolferObject encodeWithCoder:]: unrecognized selector sent to instance 0x4b7520’

— No where in my code have i alloc’d NSKeyedArchiver so I’m assuming this is something that done by core data? also my GolferObject does not have an encodeWithCoder method? I do not know where this is coming from?

Answer 1

I needed to encode before submitting to my custom object in CoreData. I needed to use the – (void)encodeWithCoder:(NSCoder *)encoder; and – (id)initWithCoder:(NSCoder *)decoder; methods.
