Fix NSPredicate

NOTE: employeename is a key in an array of multiply key value pair

NSPredicate to find result of all employee name when user type character wise search

 NSPredicate *predicate = [NSPredicate predicateWithFormat:@"employeename BEGINSWITH[cd] %@", searchtxtField.text];
 NSArray *elementFound= [arr_employeeData filteredArrayUsingPredicate:predicate];
NSLog(@"arr_add_data=%@",arr_employeeData);

(
        {
        employeename = "Anoop";
        employeeMobile = 11111111;
    },
{
        employeename = "Anoop singh";
        employeeMobile = 11111111;
    },
  {
        employeename = "Anoop kumar";
        employeeMobile = 1133111111;
    },
 {
        employeename = "Vijay kumar";
        employeeMobile = 22222;
    },

)

If your type A in search bar he will have to get all results employee name start with A and so on

I guess with your predicate is all Ok. But the result of filtered users will be in

NSArray *elementFound .

Just print it,and use it next in your program. Because this method return filtered array by predicate, but not change the original one. To change original one,

    NSMutableArray * mutab = [[NSMutableArray alloc] initWithArray:arr_employeeData];
    [mutab filterUsingPredicate:predicate];

And "mutab" array, will have filtered results
