for example “beta”,”mota”,”at work”,”ebebebatbcbcb” , i would like to have just the words witch begin with “at”, not all the words witch contain “at”.

try this:

-(NSMutableArray *)array:(NSMutableArray *)array withstart:(NSString *)string{


NSPredicate *sPredicate = [NSPredicate predicateWithFormat:@"SELF beginswith[c] %@",string];
[array filterUsingPredicate:sPredicate];
return array;
}

Or other way:

NSString *prefix = @"at";     
NSArray *final_array=[array objectsAtIndexes:[array indexesOfObjectsPassingTest:^(id obj, NSUInteger idx, BOOL *stop)
                                              {
                                                  return [obj hasPrefix:prefix];
                                              }]];
