Question

I have a toolbar which I need to use when editing text, and when not.

In previous apps, I’ve moved the toolbar manually (listening for notifications, etc.)

But I want to use inputAccessoryView… so in my viewDidLoad, I do

for (/*myTextFields*/) {
   textField.inputAccessoryView = keyboardToolbar;
}
[self.view addSubView:keyboardToolbar];

Which works fine, the toolbar appears, I click on a text field, toolbar slides up – all good.
But when I then hide the keyboard, inputAccessoryView drags my toolbar off the screen. Is there any way to tell the inputAcessoryView where it’s fixed location is? – Or do I have to go back to my old way of listening for notifications etc…?

Answer 1

I solved this by listening for Notifications and moving the toolbar up… oh well.

Something like this does the job:

- (void)viewWillAppear:(BOOL)animated 
{
    [super viewWillAppear:animated];
    /* Listen for keyboard */
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];
}
- (void)keyboardWillShow:(NSNotification *)notification 
{
    [keyboardToolbar setItems:itemSetFull animated:YES];
    /* Move the toolbar to above the keyboard */
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.3];
    CGRect frame = self.keyboardToolbar.frame;
    frame.origin.y = self.view.frame.size.height - 210.0;
    self.keyboardToolbar.frame = frame;
    [UIView commitAnimations];
}

- (void)keyboardWillHide:(NSNotification *)notification 
{
    [keyboardToolbar setItems:itemSetSmall animated:YES];
    /* Move the toolbar back to bottom of the screen */
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.3];
    CGRect frame = self.keyboardToolbar.frame;
    frame.origin.y = self.view.frame.size.height - frame.size.height;
    self.keyboardToolbar.frame = frame;
    [UIView commitAnimations];
}

I guess input accessory view is literally just meant for something stuck on top of the keyboard 🙂
