CoreData and UITableViewController Problem

Question

Hi

I have a app that works with Core Data. The data has a field with a date and I would like to show every entry of a month in a seperate section.

How do I actually get the data ? I use a NSFetchedResultsController to get the data and use this :

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{

    id <NSFetchedResultsSectionInfo> sectionInfo = [[_fetchedResultsController sections] objectAtIndex:section];
    return [sectionInfo numberOfObjects];

}

to get the rows and this :

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{
MyInfoObject *info = [_fetchedResultsController objectAtIndexPath:indexPath];
}

to get my actually data object.

Thanks

Make sure you set the sectionNameKeyPath when instantiating your fetchedResultsController

NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:@"dateKey" cacheName:@"Root"];
