inputAccessoryView with custom view hide After I Dismiss keyboard - ios

Question

First of all , my project is so structured:
-home page with a tableView to add element
-floating Button: when clicked make appear keyboard with above a custom view (and inside a textView) to digit input
Now, I have a problem with inputAccessoryView and dismiss keyboard:
I have used inputAccessoryView to move a custom view above the keyboard like this:
MytextView.inputAccessoryView= MyContainerView;
And this work correctly.
My problem occur when I dismiss keyboard using:
[MytextView resignFirstResponder];
The keyboard and relative inputView disappear properly but After when I try again to make MytextView the firstResponder does not work (the keyboard not appear).
I hypothesize that occurs because textView is hide with inputAccessoryView under the screen and inputAccessoryView change The inizial position of textview (Initial in the Middle of the screen); so textView is not focusable and keyboard not appear when I use:
[MyTextView becomeFirstResponder]
Is there a way to reposition programmatically the textView to initial position (middle of the screen) so can become focusable when I call becomeFirstResponder?
Or is there a way to fix inputAccessoryView in the safe area when i dismiss keyboard?
(Sorry , I’m New to objective-c and IOS)
Thanks!

Answer 1

Let me jump out of the comments to have more freedom. Based on your description you could do something like this
- (void) viewDidLoad
{
super.viewDidLoad;
[NSNotificationCenter.defaultCenter addObserver:self
selector:#selector( keyboardDidHide: )
name:UIKeyboardDidHideNotification
object:nil];
}
- ( void ) keyboardDidHide:( NSNotification * ) notification
{
... do stuff here...
}
Then you can reposition or do whatever you need in there. Alternatively, you can also listen for UIKeyboardDidShowNotification and do preparatory stuff there. In fact, there is a whole family of UIKeyboard... notifications that you could use this way and I hope it helps.
EDIT
Here is something else, if you ever need to reposition based on the keyboard size.
- ( void ) keyboardDidShow:(NSNotification *)notification
{
NSDictionary * info = notification.userInfo;
CGRect kbRect = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue];
... do stuff with kbRect ...
}

Answer 2

have you tried to use
[self.view endEditing:YES]
to dismiss the input view?
I never get any issue to set any input to firstResponder after I trigger that code.
