Question

I am trying to make a save button for my CoreData project, and usually I have no issues. But this time I am not seeing it save to the SQL file (using SQLite in FireFox) nor can I pull the data back in a UITableView.

There are no errors or warnings. Can someone help me with my clouded sunday afternoon (NZ time) head)??

- (IBAction)saveDataAction:(id)sender
{
//Instantiating the Entity with a pointer and giving it a mission.
NSString *details = @"Details";
NSManagedObject *newObject = [NSEntityDescription insertNewObjectForEntityForName:details inManagedObjectContext:[self managedObjectContext]];

int yearOfBirth = [_yearTxtField.text intValue]; //Converting the value from a String into an int
NSNumber *year = [NSNumber numberWithInt:yearOfBirth]; //Converting the int into a NSNumber

//Setting each textField value to an attribute in the Entity.
[newObject setValue:_nameTxtField.text forKey:@"name"];
[newObject setValue:_streetTxtField.text forKey:@"streetName"];
[newObject setValue:_cityTxtField.text forKey:@"cityName"];
[newObject setValue:year forKey:@"yearOfBirth"];

//This log just shows what has been added to the database.
//NSLog(@"Details Save:\n\n Name: %@\n StreetName: %@\n CityName: %@\n Year of birth: %@", details.name, details.streetName, details.cityName, details.yearOfBirth);
}
