I am trying to get UITextField that on which the observer UIKeyboardDidShowNotification is being called.
My Observer is in appdelegate and I have several UIViewControllers that have several UITextFields in them, in short I don't know current First Responder.
How can I get the first responder inside my Method that is fired upon the keyboard notification UIKeyboardDidShowNotification?
This is not possible to deduce from UIKeyboardDidShowNotification simply because it contains following information only. However, check this SO thread which has a brilliant solution on how to get the current first responder.
NSConcreteNotification 0x7ff14d1ac0d0 {name = UIKeyboardWillShowNotification; userInfo = { UIKeyboardAnimationCurveUserInfoKey = 7; UIKeyboardAnimationDurationUserInfoKey = "0.25"; UIKeyboardBoundsUserInfoKey = "NSRect: {{0, 0}, {320, 216}}"; UIKeyboardCenterBeginUserInfoKey = "NSPoint: {160, 676}"; UIKeyboardCenterEndUserInfoKey = "NSPoint: {160, 460}"; UIKeyboardFrameBeginUserInfoKey = "NSRect: {{0, 568}, {320, 216}}"; UIKeyboardFrameEndUserInfoKey = "NSRect: {{0, 352}, {320, 216}}"; UIKeyboardIsLocalUserInfoKey = 1; }}
