    <p>I have a navigation controller and in it a view controller:</p> <pre><code>-NavigationController1 --MyViewController </code></pre> <p>And as well I have another navigation controller - NavigationController2. I want to call MyViewController from another view controller - ViewController2, that was pushed into NavigationController2. -NavigationController2 --ViewController2</p> <p>I do it in the following way:</p> <pre><code>@implementation ModifyDicVController - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; self.navigationItem.rightBarButtonItem = [ [ [UIBarButtonItem alloc] initWithBarButtonSystemItem: UIBarButtonSystemItemAdd target:self action:@selector(add_clicked)] autorelease]; } -(void) add_clicked { [navigationController pushViewController: addWordsVController animated: YES]; } @end </code></pre> <p>And here is the viewWillAppear method of MyViewController(the one that is being called):</p> <pre><code>- (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [self setTitle: @"My title"]; } </code></pre> <p>I am adding a "done" button to the Navigation Bar when user starts to edit a text field:</p> <pre><code>- (void) textFieldDidBeginEditing: (UITextField *) textField { self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle: NSLocalizedString(@"button: done", @"") style:UIBarButtonItemStyleDone target:self action:@selector(doneEditing)] autorelease]; } </code></pre> <p>The problem is: if I call MyViewController from ViewController2 that was pushed into NavigationController2 and after that I call MyViewController from its own NavigationController1, the title of a navigation bar and a done button is not being added. However viewWillAppear and textFieldDidBeginEditing methods of MyViewController are being called.</p> <p>What is the problem and how can I fix it?</p> <p>Thanks.</p>

    2. COIt is an application similar to address book. I have a tab bar from which I can choose an address book to edit(I have several books) and as well I can choose a tab from where I can add a new contact to an active address book. Both tabs are navigation controllers. And it is possible as well to add a new contact to an address book by going into the first tab, select a particular address book to edit and from there add new contacts.

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.
