Question

Actually i’m using only one section. I sort my data stored in core data by date.

I want to have two sections (latest and history). In my first section “latest” I want to put my latest date and in the other section “history” i want to put other dates sorted by date.

My table is editable and I’m using NSFetchedResultsController.

Here is my sample code for numberOfRowsInSection:

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

    NSFetchRequest *fetchRequest = [[NSFetchRequest alloc]init];
    [fetchRequest setEntity:[NSEntityDescription entityForName:@"Info"
                                    inManagedObjectContext:self.managedObjectContext]];

    // Define how we want our entities to be sorted
    NSSortDescriptor* sortDescriptor = [[[NSSortDescriptor alloc]
                                    initWithKey:@"date" ascending:NO] autorelease];
    NSArray* sortDescriptors = [[[NSArray alloc] initWithObjects:sortDescriptor, nil] autorelease];

    [fetchRequest setSortDescriptors:sortDescriptors];

    NSString *lower = [mxData.name lowercaseString];
    NSPredicate *predicate = [NSPredicate predicateWithFormat: @"(name = %@)", lower];

    [fetchRequest setPredicate:predicate];

    NSError *errorTotal = nil;
    NSArray *results = [self.managedObjectContext executeFetchRequest:fetchRequest error:&errorTotal];

    if (errorTotal) {
        NSLog(@"fetch board error. error:%@", errorTotal);
    }

    return [results count];

    [fetchRequest release];
    [results release];
}

You need to modify your designated “UITableViewDataSource” object to return “2” for the “numberOfSectionsInTableView:“ method.

Then you need to return the right thing in your “tableView:cellForRowAtIndexPath:“ method, depending on the section designated in the index path.

If you want an optional section title (e.g. “History” or “Latest”), you can also return an array of section titles via sectionIndexTitlesForTableView:.
