I am using UIKeyboardWillShowNotification
to detect when a textfield is selecting by user and the keyboard is opening. In ios 8 and older versions of iOS it is working fine but today I upgrade to iOS 9 and xCode 7. the problem is that in iOS now the notification is called after selecting each textfields (while in ios 8 only called after selecting first textfield).
I searched about this and find some post like Why is UIKeyboardWillShowNotification called every time another TextField is selected?
but it is not about iOS 9 (actually every thing was right in iOS8 and by upgrading I see the problem) and I am not using inputAccessoryViews too.
