Indexed list for table view shows dot iOS 5+ - list

Question

In my application I am displaying contacts in table view with indexed list. I am displaying indexed list as follow:
static NSString *letters = #"abcdefghijklmnopqrstuvwxyz#";
-(void)getAllUserInfoUsingBlock:(lclResultsArray) block
{
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^{
NSMutableArray *allUserInfoArray = [[NSMutableArray alloc]init];
NSLog(#"[letters length]:- %d",[letters length]);
for (int i = 0; i < [letters length]; i++ ) {
NSMutableDictionary *row = [[NSMutableDictionary alloc] init];
char currentLetter[2] = { toupper([letters characterAtIndex:i]), '\0'};
NSString *str=[NSString stringWithCString:currentLetter encoding:NSASCIIStringEncoding];
NSMutableArray *words = nil;
NSLog(#"Value of i:- %d:: Letter:- %#",i,str);
if (i<[letters length]) {
words = [self getUserInfoByStartingCharOfLastName:str isForEmptyValue:NO];
}
else {
// Get users where name is empty
words = [self getUserInfoByStartingCharOfLastName:#"" isForEmptyValue:YES];
}
NSLog(#"Count for %# :- %d",str,words.count);
[row setValue:str forKey:#"sectionTitle"];
[row setValue:words forKey:#"sectionRows"];
[allUserInfoArray addObject:row];
}
dispatch_async(dispatch_get_main_queue(), ^{
for (NSDictionary *dict in allUserInfoArray) {
NSLog(#"Array count:- %d",[[dict objectForKey:#"sectionRows"]count]);
}
block(allUserInfoArray,nil);
});
});
}
- (NSString *)tableView:(UITableView *)aTableView titleForHeaderInSection:(NSInteger)section
{
if (aTableView != self.searchDisplayController.searchResultsTableView){
NSMutableDictionary *sections=[self.contactsArray objectAtIndex:section];
NSString * sectionTitle= [sections objectForKey:#"sectionTitle"];
return sectionTitle;
}
return nil;
}
- (NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index
{
if (tableView != self.searchDisplayController.searchResultsTableView){
NSMutableDictionary *sections=[self.contactsArray objectAtIndex:index];
NSString * sectionTitle= [sections objectForKey:#"sectionTitle"];
return [self.indices indexOfObject:sectionTitle];
}
return 0;
}
- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView {
if (tableView != self.searchDisplayController.searchResultsTableView){
return [self.contactsArray valueForKey:#"sectionTitle"];
}
return nil;
}
But it displays as shown in following images
As you can see in first image its displaying A.C.E .... V.X.Z# Its displaying alternate dots(.) after every character.But as shown in second image its dispalying correct headet title for table from ABC....XYZ#
Whats wrong in my implementation ?

Answer 1

Alternative dots between characters in indexed list depends upon display height of that indexedlist.if we can increase the tableSize .it will be automatically display whole characters.
