    copied!<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>
