Refresh input bar

Hi,
I wanted to have multiple input items which is enable to select depend on the last message received. Currently i manage to observe last message then force it to refresh using ```super.viewDidLoad()```, the problem is the input bar will be duplicated.
So is it possible to make ```inputView``` refresh with new ```createChatInputView```?
I'm pretty new for swift so i'm really appreciate any direction.

Thank you.

Start by tracing how inputView and createChatInputView are used, then reproduce the refresh triggered after observing the last message and calling super.viewDidLoad(). Done should allow the input items to change based on the last message without duplicating the input bar.
