    <p>Editable TextView with Second NavBar - Text appears, but too late.</p> <p>The app has a single Navigation Controller. I have an iPhone App that has basically three levels.</p> <ol> <li><p>Level 1 - Table with category Names</p></li> <li><p>Level 2 - Table with list of items for selected category</p></li> <li><p>Level 3 - Tabbed View with several views, including UITextView for details of item One to these Tabbed Views with a TextView is editable.</p> <p>When the user taps in the editable TextView the KeyBoard appears. User can type in the TextView. Characters appear as they are typed.</p> <p>At the top of this Level 3 TextView there is a NavBar (present for all 3 levels with changes) with a BackButton and a "home->Level1" button on the right.</p></li> </ol> <p>All works just fine until in the editable TextView I add a second NavigationBar below the existing NavBar. This second NavBar has two buttons as well. They are Save/Cancel.</p> <p>When I click these Save and Cancel buttons the correct action methods are reached. All is perfect with one exception, The text which is typed does not appear in the TextView until either the Save or the Cancel button is touched. The relevant Button setup and action methods in my <code>TabViewController.m</code> are below. I need to persist this data.</p> <p>I thought that getting a Notification from the TextView and the action handleTextChange would do the trick, but no luck. I am stuck.</p> <pre><code>......... - (void)loadView { self.myTextView = [[UITextView alloc] init]; self.myTextView.delegate = self; self.view = self.myTextView; //UITextViewTextDidChangeNotification NSNotificationCenter *nc = [NSNotificationCenter defaultCenter]; [nc addObserver:self selector:@selector(handleTextChange:) name:UITextViewTextDidChangeNotification object:nil]; NSLog(@"Registered DG_HandleChangeTextNotification with notification center."); } - (void)handleTextChange:(NSNotification * )note { [self.myTextView setNeedsDisplay] ; NSLog(@"...Handled Text Change."); } - (void)textViewDidBeginEditing:(UITextView *)textView { // provide my own Done/Save button to dismiss the keyboard saveNavigationBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)]; saveNavigationBar.barStyle = UIBarStyleBlackOpaque; UINavigationItem *doneItem = [[UINavigationItem alloc] init]; doneItem.title = @"My Notes"; UIBarButtonItem *doneItemButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemSave target:self action:@selector(saveAction:)]; UIBarButtonItem *cancelItemButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:@selector(cancelAction:)]; [doneItem setRightBarButtonItem:doneItemButton animated:NO]; [doneItem setLeftBarButtonItem:cancelItemButton animated:NO]; [saveNavigationBar pushNavigationItem:doneItem animated:NO]; [self.view addSubview:saveNavigationBar]; [doneItem release]; [cancelItemButton release]; [doneItemButton release]; } - (void)saveAction:(id)sender { // finish typing text/dismiss the keyboard by removing it as the first responder self.text = self.myTextView.text; [self.saveNavigationBar removeFromSuperview]; [self.myTextView resignFirstResponder]; } - (void)cancelAction:(id)sender { [self.saveNavigationBar removeFromSuperview]; [self.myTextView resignFirstResponder]; } </code></pre>

    1. COThe Second NavBar was hiding the area of the UITextEdit such that I had to type about four lines before I saw the text. I believe I need to lower the height of the UITextEdit by 44 pixels.

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.
