how to hide section title if result not found using searchbar in ios8

Question

IF Name is present then it will look like this

IF Name is not present then it look like this i want to hide section title if name is not present

-(NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView
{
    if (_segment.selectedSegmentIndex==0)
    {
        return sortedKeys;
    }
    else
    {
       return sortedKeys1;
    }
}

I use this code but i don't want section title if name is not present , now its give me all section titles

see this lines- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { if (_segment.selectedSegmentIndex==0) { return ([sortedKeys count]); } else { return ([sortedKeys1 count]); } } — Asmita, Oct 14 '15 at 08:34
Do you try to return 0 in `numberOfSectionsInTableView` if `result not found`? Or [sortedKeys count], [sortedKeys1 count] is equal 0 already? — tuledev, Oct 14 '15 at 08:36

If there is no rows than set the title of the section to nil.

-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
    if ([tableView.dataSource tableView:tableView numberOfRowsInSection:section] == 0)
 {
                return nil;
    } else {
        return "section title \(section)"
    }
   return @"";
}

This will work.

Try return 0 in numberOfSectionsInTableView

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { 

     if (result_not_found) { /// pass the condition when "result not found" here
        return 0;
     }

     if (_segment.selectedSegmentIndex==0) { 
        return ([sortedKeys count]); 
     } 
     else { 
        return ([sortedKeys1 count]); 
     } 
}

You should either use this one returning the correct number of sections :

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView;

Or this one returning CGFLOAT_MIN if there is no rows in the corresponding section :

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section;

Hope it helps.
