From c506d938a83585d973cbc369e99503cf83db68e2 Mon Sep 17 00:00:00 2001 From: Richard Moe Gustavsen Date: Wed, 12 Nov 2014 12:28:16 +0100 Subject: iOS: close menu when keyboard hides MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If the menu is closed from the keyboard gesture, and the focus object doesn't change, the menu will still be in a visible state, even if the keyboard is hidden. This patch will ensure that this can not be the case by listening for keyboardWillHideNotification. Since we have no guarantee for when the destructor runs, we apply a pessimistic approach and ensure we stop listen when the menu gets closed.
