In our upcoming release we have added a delegate method called tableViewModel:itemCreatedForSectionAtIndex:item: . You can use the following code to achieve what you want as soon as the managed object is created (I'll send you a pre-release RC version on your email):
- (void)tableViewModel:(SCTableViewModel *)tableViewModel
itemCreatedForSectionAtIndex:(NSUInteger)index item:(NSObject *)item
{
// This step is not actually neccessary but I included it just for clarity
NSManagedObject *managedObject = (NSManagedObject *)item;
// Now assuming you have attributes called "latitude" and "longitude"
[managedObject setValue:currentLatitude forKey:@"latitude"];
[managedObject setValue:currentLongitude forKey:@"longitude"];
}
That should do the trick!
