                name = "Amit Patel";
               },
               {
                address = "Junagdh";
                "main_id" = 5;

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];

There are quite some issues with this code ...

The first indexPath.row has to be indexPath.section.

As a general hint, it would be better to organize your code more readable, like:

NSArray* nameArrayForLetter = [self.finalPDic objectForKey:[self.listOfHeader objectAtIndex:indexPath.section];
NSDictionary* addressDict = [nameArrayForLetter objectAtIndex:indexPath.row];
NSString* nameString = [addressDict objectForKey:@"name"];

Your code iterates through the root keys one by one, but you wont start by index 0 in the lower levels. (the S key is the 4th, so you want the 3rd item it that array, which doesnt exists.

try using sections. A..S is the section and the rows are the names!
