Answer 1

If you are using Autolayout check if the tabbar has a constraint to be on the bottom. If not check wether the tabbar is "fixed" on the bottom with the autoresize feature of your View.

This is the Autoresize Feature but not correct for your tabbar your tabbar would need the bottom restriction
