Making Quick Jumbar with custom input/array in TableViewController

I have implemented quick jumpbar using the following delegate functions

sectionIndexTitlesForTableView and sectionForSectionIndexTitle

- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView {  
return [NSArray arrayWithObjects:@"0",@"50",@"100",@"150",@"200",nil];
}

but I need to put a dot image in between the numbers for which I have to pass a custom object and then handle the same as it is.

Can an开发者_如何转开发y one tell me how to do this, including source code?

The . image is added automatically when there are to many item in the list.
