- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

       {
           RightViewController *rightViewController = [[RightViewController alloc] initWithNibName:@"RightViewController"bundle:nil];
           //[self.navigationController pushViewController:rightViewController animated:YES];

           if(indexPath.row == 0)
           {
               UILabel *infoLabel = [[UILabel alloc]initWithFrame:CGRectMake(5, 5, 450, 150)];
               infoLabel.text = @"Customer:Barrick \r\n Mine:gold \r\n Location:USA";
               [rightViewController.view addSubview:infoLabel];

               UITableView *mapTable = [[UITableView alloc]initWithFrame:CGRectMake(165, 5, 450,150)style:UITableViewStyleGrouped];
               [rightViewController.view addSubview:mapTable];
           }

           if(indexPath.row == 1)
           {
               UILabel *infoLabel = [[UILabel alloc]initWithFrame:CGRectMake(5, 5, 450, 150)];

           [rightViewController release];
       }

Answer 1

You have to pass a value to the right view controller and you have to also set delegate for your right view controller.

Define your right View Controller in your left view controller like:

RightViewController *detail;
  /// in implementation of left view contrloller
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{ 
    NSUInteger item = [indexPath row] +1;
    NSNumber *detailItem = [NSNumber numberWithInteger:item];
    self.detailCar.detailItem = detailItem;
}

Define in your rightViewController.h file :

@property (retain, nonatomic) NSNumber *detailItem;

In Your RightViewController’s implementation file:

- (void)setDetailItem:(NSNumber *)newDetailItem {
    NSLog(@"ConfigTItem");
    if (_detailItem != newDetailItem) {
        [_detailItem release]; 
        _detailItem = [newDetailItem retain]; 
        [self configureView];
    }
    else {
        [self configureView]; 
    }
}

- (void)configureView {        
    if (self.detailItem) {
        [self viewDidLoad];  // 
        //set your method's and variable whatever you want to do in your view did load or directly here
    }
}
