How to hide section title if result is not found using search bar in ios8

Question

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

I use this code, but I don’t need the section title, if the name is missing, now it gives me all the section titles

Answer 1

If there are no lines, set the section title 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.

Answer 2

Try returning 0 to 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]); } } 

Answer 3

You should either use this by returning the correct number of partitions:

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

Or this returning CGFLOAT_MIN if there are no lines in the corresponding section:

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

Hope this helps.
