who is issuing my UIKeyboardDidHideNotification?

Question

I want to register to UIKeyboardDidHideNotification that only my UIViewController is issuing.

When I do :

    [[NSNotificationCenter default

You have no way to register for a UIKeyboardDidHideNotification coming from a specific controller.

If using UIKeyboardWillHideNotification, you could check if one of the UITextView inside your controller is the first responder.

Using UIKeyboardDidHideNotification I guess you need to use delegate methods for all your UITextView and save the last one that was edited. I don't think of any other alternative.

Else, if the issue is to perform the method called by UIKeyboardDidHideNotification only on the visible controller, the solution by @sviatoslav-yakymiv works well.
