Editable TextView with Second NavBar - Text appears, but too late - iphone

Question

Editable TextView with Second NavBar - Text appears, but too late.
The app has a single Navigation Controller.
I have an iPhone App that has basically three levels.
Level 1 - Table with category Names
Level 2 - Table with list of items for selected category
Level 3 - Tabbed View with several views, including UITextView for details of item
One to these Tabbed Views with a TextView is editable.
When the user taps in the editable TextView the KeyBoard
appears. User can type in the TextView. Characters appear
as they are typed.
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.
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.
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 TabViewController.m are below. I need to persist this
data.
I thought that getting a Notification from the TextView and the action handleTextChange would do the trick, but no luck. I am stuck.
.........
- (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];
}

Answer 1

The 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.
