Big gap between q-footer and virtual keyboard in iOS devices

[chechin]

Hi all, I’m creating a chatting app and using q-footer as container of message input field. I am facing some UI issue in iPhone browsers including Safari and Chrome. When I tap on the q-input, and scroll the page to the most bottom, there is a big white gap between the q-input and the virtual keyboard. Anyone has idea how to overcome this? So that the q-footer will stick to bottom and just on top of the virtual keyboard all the time? Btw this issue does not happen in Android devices.
