    <p>I have two views with navigation controller: first view, there are empty text fields while the second view is a table view where the user can select a row. At the touch of a row there is an action that sets a value to a text field of the first view. Unfortunately when I go back to the first view field is not set.</p> <p>This is my code:</p> <p>FirtViewController.h</p> <pre><code> @interface FirstViewController : UIViewController { UITextField *firstField; UITextField *secondField; } @property(nonatomic, retain) IBOutlet UITextField *firstField; @property(nonatomic, retain) IBOutlet UITextField *secondField; @property(copy) NSString *selectedRow; -(IBAction)showTable:(id)sender </code></pre> <p>FirstViewController.m</p> <pre><code> #import "FirstViewController.h" #import "AppDelegate.h" #import "SecondViewController.h" @implementation FirstViewController @synthesize ..... ............. -(void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; self.firstField.text = selectedRow; } -(IBAction)showTable:(id)sender { SecondViewController *controllerSecond = [[SecondViewController alloc] initWithNibName:@"SecondViewController" bundle:nil]; [self.navigationController pushViewController:controllerSecond animated:YES]; } </code></pre> <p>SecondViewController.h</p> <pre><code> @class FirstViewController; @interface ListaViewController : UIViewController &lt;UITableViewDataSource, UITableViewDelegate, UISearchBarDelegate&gt; { UITableView *table; UISearchBar *search; FirstViewController *controller; } @property (nonatomic, retain) FirstViewController *controller; </code></pre> <p>SeconViewController.m</p> <pre><code> - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSString *selectedRow = [tableData objectAtIndex:indexPath.row]; controller.selectedRow = selectedRow; [self.navigationController popViewControllerAnimated:YES]; } </code></pre>

    1. COPlease show where in FirstViewController.m you load SecondViewController. That is where you have to link SecondViewController back to First.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
