Core Data not saving NSString

Question

Currently seeing an issue in my Core Data saving. For some reason a NSString isn't being saved properly, always returning 0 regardless. Below is my current code.

appDelegate =(NotaciousAppDelegate *) [[UIApplication sharedApplication] delegate];

        NSEntityDescription *entity = [NSEntityDescription entityForName:@"Note" inManagedObjectContext:appDelegate.managedObjectContext];
        NSArray *fetchedNotes;

        NSArray *notes = [object valueForKey:@"result"];
        for (NSDictionary *singleNote in notes){

            noteFetch=[[NSFetchRequest alloc] init];
            [noteFetch setEntity:entity];
            NSPredicate *pred=[NSPredicate predicateWithFormat:@"ID==%@",[singleNote objectForKey:@"note id"]];
            [noteFetch setPredicate:pred];

            NSError *fetchError=nil;
            fetchedNotes=[appDelegate.managedObjectContext executeFetchRequest:noteFetch error:&fetchError];

            if (fetchError!=nil) {
                NSLog(@"syncNotes fetchError=%@,details=%@",fetchError,fetchError.userInfo);
            }
            if ([fetchedNotes count]==0) {


                NSString *notelocked = [singleNote objectForKey:@"note locked"];

                NSString *notecreated = [singleNote objectForKey:@"note created"];
                NSString *noteupdated = [singleNote valueForKey:@"note updated"];
                NSString *notetitle = [singleNote objectForKey:@"note title"];
                NSString *notesummary = [singleNote objectForKey:@"note summary"];
                NSString *noteid = [singleNote objectForKey:@"note id"];
                NSString *notecontent = [singleNote objectForKey:@"note content"];

                NSString *formattedTitle = [NSString decodeShit:notetitle];
                NSString *formattedSummary = [NSString decodeShit:notesummary];
                NSString *formattedContent = [NSString decodeShit:notecontent];


                NSLog(@"Note Title: %@",formattedTitle);
                NSLog(@"Note Summary: %@",formattedSummary);
                NSLog(@"Note ID: %@",noteid);
                NSLog(@"Note Content: %@",formattedContent);
                NSLog(@"Note Created: %@",notecreated);
                NSLog(@"Note Updated: %@",noteupdated);
                NSLog(@"Note Locked: %@",notelocked);

                newNote = [NSEntityDescription insertNewObjectForEntityForName:@"Note" inManagedObjectContext:appDelegate.managedObjectContext];
                [newNote autorelease];

                [newNote setValue:formattedContent forKey:@"content"];
                [newNote setValue:formattedSummary forKey:@"summary"];
                [newNote setValue:formattedTitle forKey:@"title"];
                [newNote setValue:noteid forKey:@"ID"];
                [newNote setValue:notecreated forKey:@"created"];
                [newNote setValue:noteupdated forKey:@"updated"];
                [newNote setValue:notelocked forKey:@"locked"];

                NSLog(@"Note Updated in MOC:%@",[newNote valueForKey:@"updated"]);

                NSError *error = nil;
                if (![appDelegate.managedObjectContext save:&error]) {
                    NSLog(@"Unresolved error %@, %@", error, [error userInfo]);
                    abort();
                }


            }

            [noteFetch release];

        }

The issue arises when trying to save the updated string. For some reason, regardless of what string is in there, it will not save to the Core Data attribute.

I'm struggling to find any coherent reason for it to not be saving, but I'm about to deem it possible. This is the last issue that needs to be sorted before this application can hit the shelves. Any help would be great!

Edit

There is no error, only the following output in the debug console.

Answer 1

Are you really sure "note updated" in the dictionary is not an NSDate instead of an NSString? The log output makes it look an AWFUL lot like you have an NSDate in there.

You would need to use an NSDateFormatter to save it into an NSString object property if so.

Answer 2

The following code has worked.

appDelegate =(NotaciousAppDelegate *) [[UIApplication sharedApplication] delegate];

        NSEntityDescription *entity = [NSEntityDescription entityForName:@"Note" inManagedObjectContext:appDelegate.managedObjectContext];
        NSArray *fetchedNotes;

        NSArray *notes = [object valueForKey:@"result"];
        for (NSDictionary *singleNote in notes){

            noteFetch=[[NSFetchRequest alloc] init];
            [noteFetch setEntity:entity];
            NSPredicate *pred=[NSPredicate predicateWithFormat:@"ID==%@",[singleNote objectForKey:@"note id"]];
            [noteFetch setPredicate:pred];

            NSError *fetchError=nil;
            fetchedNotes=[appDelegate.managedObjectContext executeFetchRequest:noteFetch error:&fetchError];

            if (fetchError!=nil) {
                NSLog(@"syncNotes fetchError=%@,details=%@",fetchError,fetchError.userInfo);
            }
            if ([fetchedNotes count]==0) {

                NSString *notelocked = [singleNote objectForKey:@"note locked"];

                NSString *noteupdated = [singleNote valueForKey:@"note updated"];
                NSString *notecreated = [singleNote objectForKey:@"note created"];
                NSString *notetitle = [singleNote objectForKey:@"note title"];
                NSString *notesummary = [singleNote objectForKey:@"note summary"];
                NSString *noteid = [singleNote objectForKey:@"note id"];
                NSString *notecontent = [singleNote objectForKey:@"note content"];

                NSString *formattedTitle = [NSString decodeShit:notetitle];
                NSString *formattedSummary = [NSString decodeShit:notesummary];
                NSString *formattedContent = [NSString decodeShit:notecontent];

                newNote = [NSEntityDescription insertNewObjectForEntityForName:@"Note" inManagedObjectContext:appDelegate.managedObjectContext];

                [newNote setValue:formattedContent forKey:@"content"];
                [newNote setValue:formattedSummary forKey:@"summary"];
                [newNote setValue:formattedTitle forKey:@"title"];
                [newNote setValue:noteid forKey:@"ID"];
                [newNote setValue:notecreated forKey:@"created"];
                [newNote setValue:noteupdated forKey:@"noteupdated"];
                [newNote setValue:notelocked forKey:@"locked"];

                NSError *error = nil;
                if (![appDelegate.managedObjectContext save:&error]) {
                    NSLog(@"Unresolved error %@, %@", error, [error userInfo]);
                    abort();
                }


            }

            [noteFetch release];

        }

It seems that CoreData didn't like me accessing an attribute with the name updated .
