Question

I want checked more cell with one click(touch).

In this code I try to do what I said bat … I have some problem

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *riga;
int esci=0;
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];

NSDictionary *itemAtIndex = (NSDictionary *)[listad objectAtIndex:indexPath.row];
riga=[itemAtIndex objectForKey:@"riga"];

for (int i=0; i<[righeS count]; i++) {
    if ([righeS objectAtIndex:i] ==riga) {
                cell.accessoryType=UITableViewCellAccessoryNone;
        //[tableView deselectRowAtIndexPath:indexPath animated:YES];
        [righeS removeObjectAtIndex:i];
                     esci=1;
        }
}

if (esci==0) {

    [righeS addObject:riga];
             cell.accessoryType = UITableViewCellAccessoryCheckmark;


             //Check if value of qty of the next row is 0
             bool trovato=FALSE;
         for (int g =0 ;g <[listad count];g++){
             NSDictionary *rigaScan=(NSDictionary*)[listad objectAtIndex:g];
            if (trovato==TRUE) {
                 if ([[rigaScan objectForKey:@"qty"] isEqualToString: @"0"]){
                     NSString *rig;
                     rig=[rigaScan objectForKey:@"riga"];
                     [righeS addObject:rig];

                    cell.accessoryType=UITableViewCellAccessoryCheckmark;
                }else{
                   break;
                }    
            }
            if ([rigaScan objectForKey:@"riga"]==riga){
               trovato=TRUE;
            }

           [rigaScan release];
       }

           //Fine controllo


}


}

In this event I try when the user touches a cell to see if some value of the next cell is 0.
If the value is 0, I have to check also the next cell and the other value in the for iterate.
When the next value is !=0 I put break.

I believe that the logical code is correct but maybe not the syntax for cocoa.
