UIKeyboard will change frame with interactive keyboard dismiss, not called continuously

Question

I am trying to use the UITableView.keyboardDismissMode = UIScrollViewKeyboardDismissMode.Interactive, to be able to drag my keyboard up and down. However I can't find any way to track the keyboard frame to update my tableView frame and messaging view. I am simply trying to replicate the standard iMessage behaviour. Given the name, I would have thought that UIKeyboardWillChangeFrameNotification would have been perfect for tracking the keyboard frame changes, but it only notifies when the gesture ends and the keyboard animates up or down.

I'm not sure if this will work but you could try to track the drag progress via the panGesture property on UIScrollView in your tableView. It wouldn't be a direct tracking of the keyboard frame, but if you know the keyboard's height and the progress/offset of the pan, you might be able to math your way around the problem.

The best approach for interactive dismissal is to use the "UIKeyboardDidShowNotification" and "UIKeyboardWillHideNotification" system notifications. When the selector is called you update the table's bottom inset. NOT the constraints. Updating the inset will give you a beautiful smooth keyboard dismissal experience.

This doesn't update and follow the interaction of the keyboard. – Michael Dec 10 '15 at 21:45
