Usage

Example project included (./Example)

Adding pan-to-dismiss (functionality introduced in iMessages)

Frame based action handler

view.addKeyboardPanning(frameBasedActionHandler: { keyboardFrameInView, firstResponder, opening, closing in
    // Move interface objects accordingly
    // Animation block is handled for you
})
// Make sure to call self.view.removeKeyboardControl before the view is released.
// (It's the balancing call)

Constraint based action handler

view.addKeyboardPanning(constraintBasedActionHandler: { keyboardFrameInView, firstResponder, opening, closing in
    // Move interface objects accordingly
    // Animation block is handled for you
})
// Make sure to call self.view.removeKeyboardControl before the view is released.
// (It's the balancing call)

Adding keyboard awareness (appearance and disappearance only)

Frame based action handler

view.addKeyboardNonpanning(frameBasedActionHandler: { keyboardFrameInView, firstResponder, opening, closing in
    // Move interface objects accordingly
    // Animation block is handled for you
})
// Make sure to call self.view.removeKeyboardControl before the view is released.
// (It's the balancing call)

Constraint based action handler

view.addKeyboardNonpanning(constraintBasedActionHandler: { keyboardFrameInView, firstResponder, opening, closing in
    // Move interface objects accordingly
    // Animation block is handled for you
})
// Make sure to call self.view.removeKeyboardControl before the view is released.
// (It's the balancing call)

Supporting an above-keyboard input view

The keyboardTriggerOffset property allows you to choose at what point the user’s finger “engages” the keyboard.

view.keyboardTriggerOffset = 44.0;	// Input view frame height

view.addKeyboardNonpanning(frameBasedActionHandler: { keyboardFrameInView, firstResponder, opening, closing in
    // Move interface objects accordingly
    // Animation block is handled for you
})
// Make sure to call self.view.removeKeyboardControl before the view is released.
// (It's the balancing call)

Dismissing the keyboard (convenience method)

view.hideKeyboard()

Remove the NSNotification observer at the end of a VC’s life (convenience method)

view.removeKeyboardControl()

TKKeyboardControl was made with ARC enabled by default.
