            }
        }
    }

}];

Error on this line :

NSLog(@"Update Walk Location = %@",response);

"dest_latitude" = 0;
"dest_longitude" = 0;
error = "Service not yet started";
"error_code" = 414;
"is_cancelled" = 0;
"payment_type" = "";
success = 0;
unit = kms;

Getting the null for payment_type...but getting crash on this line

payment=[[response valueForKey:@"payment_type"] boolValue];

Dot know how to handle that. But this print function itself not printing :

NSLog(@"Something To Print");
NSLog(@"%d", payment);
NSLog(@"Something To Print");

Any idea on how to handle this?

Updated :

  if([response valueForKey:@"payment_type"] != nil || ![[response valueForKey:@"payment_type"] isEqualToString:@""]){
                         payment=[[response valueForKey:@"payment_type"] boolValue];
                         NSLog(@"Something To Print");
                         NSLog(@"%d", payment);
                         NSLog(@"Something To Print");

                         if (payment==0)
                         {
                             self.lblPayment.text = NSLocalizedString(@"CARD", nil);
                             self.imgCashCard.image = [UIImage imageNamed:@"card"];
                         }
                         else if (payment==1)
                         {
                             self.lblPayment.text = NSLocalizedString(@"CASH", nil);
                             self.imgCashCard.image = [UIImage imageNamed:@"cash"];

                         }
                        }
