Scroll Index localized NSHipster

This is freaking sweet:

- (NSString *)tableView:(UITableView *)tableView
titleForHeaderInSection:(NSInteger)section
{
    return [[[UILocalizedIndexedCollation currentCollation] sectionTitles] objectAtIndex:section];
}

- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView {
    return [[UILocalizedIndexedCollation currentCollation] sectionIndexTitles];
}

- (NSInteger)tableView:(UITableView *)tableView
sectionForSectionIndexTitle:(NSString *)title
               atIndex:(NSInteger)index
{
    return [[UILocalizedIndexedCollation currentCollation] sectionForSectionIndexTitleAtIndex:index];
}

This is freaking sweet:

Localized scroll index that shows up on the right of a tableview.  No need to create all the different arrays of localized sections.

Here's some code to make this a little more complete:

    self.tableView.sectionIndexColor = [UIColor colorWithWhite:.5 alpha:1.0];

    self.tableView.sectionIndexTrackingBackgroundColor = [UIColor colorWithWhite:.4 alpha:.2];
