Please check out this code
- (BOOL)searchDisplayController:(UISearchDisplayController *)controller shouldReloadTableForSearchString:(NSString *)searchString
{
NSMutableArray *array=[[NSMutableArray alloc]init];
NSDictionary *naming= [self.friendsDictionary objectForKey:#"data"];
NSLog(#"ggg %#",[self.friendsDictionary objectForKey:#"data"]);
for(int i =0 ; i< [[self.friendsDictionary objectForKey:#"data"] count]; i++){
[array addObject:[[[self.friendsDictionary objectForKey:#"data"] objectAtIndex:i] objectForKey:#"name"]];
}
NSLog(#"Array %#", array);
if(self.searchDisplayController.searchBar.text.length>0)
{
NSString *strSearchText = self.searchDisplayController.searchBar.text;
NSMutableArray *group = [[NSMutableArray alloc]init];
for (int i=0; i<array.count; i++) {
NSString *strData = [array objectAtIndex:i];
NSLog(#"string Data:%#",strData);
NSRange rng = [strData rangeOfString:strSearchText options:NSCaseInsensitiveSearch];
if(rng.location != NSNotFound)
{
if(rng.location== 0)//that is we are checking only the start of the names.
{
[group addObject:strData];
}
}
}
if ([group count] > 0)
{
searchData = [[NSMutableArray alloc] init];
[searchData addObjectsFromArray:group];
NSLog(#"Sear %#", searchData);
}
}
return YES;
}
