iOS7: How to implement Section Index like Contacts on iOS7?
In iOS7, the Section Index of Contact app shows fewer indexes.
For example, "A ● C ● E ... M ● P ● R..."
I know these two delegate methods:
-(NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView
-(NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex
But I don't know how to implement such an shorter index. Can anyone gives me a hint?
Thanks very much!
--edit--
Take a look at the index: "M ● P ● R...", if I swipe from 'M' to 'P', tableView shows section 'M' then 'N' then 'O' and then 'P', which means it uses three indexes index to 4 sections.

All right, this kind of index is automatically generated.
If the frame of table is not large enough to show the index, then the index is shown as a doted index.
That is an automatic behavior of the standard index. The index in Contacts is a normal index with all the chars, but you are using an iPhone 4 or 4s and when there are not enough space some letters are replaced with dots. If you open the app with a iPhone 5 or 5s you will see all the letters.
Could this be what you are looking for ? Hum I've replace dot per heart ;-D
- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView {
NSMutableArray *ma = [NSMutableArray arrayWithArray:@[@"A",@"♥",@"C",@"♥",@"E"]];
[ma insertObject:UITableViewIndexSearch atIndex:0]; //add magnifier at top
return ma;
}
