Adding section and index list with custom cell, searchdisplaycontroller - ios

Question

I have created a UITableView with custom cell & stored name,no,pincode in to these cell.
Here is my Code for array:-
for (int i =0; i<[tempArr count]; i++)
{
NSString *rawData = [tempArr objectAtIndex:i];
if (rawData !=nil)
{
Persons *newPerson = [[Persons alloc]init];
NSArray *data = [rawData componentsSeparatedByString:#"\t"];
newPerson.name = [NSString stringWithFormat:#"%#",[data objectAtIndex:0]];
newPerson.no = [[data objectAtIndex:1] integerValue];
newPerson.pincode = [[data objectAtIndex:2] integerValue];
[allPersons addObject:newPerson];
}
}
Here is my Customcell.h
#interface Customcell : UITableViewCell
#property(weak) Persons* person;
#end
UITableView Datasrouce method:-
-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
Customcell *cell = [tblStations dequeueReusableCellWithIdentifier:#"personCell"];
if (tableView == self.searchDisplayController.searchResultsTableView)
{
cell.person = filteredContentList[indexPath.row];
[cell.textLabel setText:cell.person.name];
}
else
{
cell.person = allPersons[indexPath.row];
[cell.textLabel setText:cell.person.name];
}
return cell;
}
How do i create Section & index list for all names from A to Z & give title by cell.textLabel.text?
I am following This Tutorial but it has static keys & names added to NSDictionary,NSArray.
In my example i do not know how many names starting with same letter can come in the array. i am also using UISearchDisplayController for search person name.
I want to add number of sections & title for those sections by names that is in the array or cell.textLabel.text dynamically.
i do not know about UISearchDisplayController that these sections & index list will be displaying in UISearchDisplayController so i do not want these sections & index list while searching.

You need to spend a little more time trying to make your questions more clear.
Include a custom implementation of the necessary UITableView data source and delegate methods...
NOTE my assumption that your variable allPersons is an NSMutableArray.
NOTE these do not include for your search results data sets!
Return an NSInteger for the number of sections in your UITableView...
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
NSSet *setData = nil;
NSInteger integerData = 0;
setData = [NSSet setWithArray:allPersons];
integerData = [setData count];
return integerData;
}
UPDATE
Return an NSString for section header titles...
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
NSOrderedSet *setData = nil;
NSString *stringData = nil;
setData = [NSOrderedSet orderedSetWithArray:allPersons];
stringData = [[setData allObjects] componentsJoinedByString:#" "];
return stringData;
}
...plus others if I have the time...
