As a quick summary, the gist is that you need to implement two methods:

-(NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView {
    //The array of strings to use as indices
}

-(NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index {
    //The index (integer) of the current section that the user is touching
}

You can sort the array by using this code.

sortedArray = [yourArray sortedArrayUsingSelector:@selector(localizedCaseInsensitiveCompare:)];

checkout the apple's Documentation for more details

You can use segmented table withsorted array, if you want segementation according to alphabate. and to full fill the requirnment of sorted data display.. you only need to sort the source of data.
