I have a custom view that I am using as inputAccessoryView
for my tableViewController
.
the tableViewControlleris
inside a tabBarViewController
which is inside a navigation controller.
I managed to make the custom view appear correctly as the inputAccessoryView
, appearing at the bottom, and when focused it goes up with the keyboard.
My problem is that it's hiding my tabBar
, I searched but couldn't find anything except for a 2years old unanswered question.
I want my view to appear above the tabBar
, similar to the music app when having a song playing, the song and the play button and the next button appear above the tabBar
not hiding it.
using swift 4.2, Xcode 10.1, iOS 11 target, testing on iOS 12.1 and 12.1.1
I have been able to achieve this effect and made a framework called AMKeyboardFrameTracker to do just that
but first you need to understand how the inputAccessoryView
work
inputAccessoryView
is attached to another window called UITextEffectsWindow
this window shows on top of your main app window
The main feature of using inputAccessoryView
is the interactive keyboard dismissal effect with any UIScrollView
because normally you can't get the keyboard frame from the native keyboard notifications callbacks
But with AMKeyboardFrameTracker I've been able to get the keyboard frame from the inputAccessoryView's
superview
by observing it's frame changes, so it's still using inputAccessoryView
but with an empty view that has no user interaction
There is an Example in the Github repo you can download it and try it out
Note
in the example app I am using a normal ViewController
instead of a TableViewController
if you'd like to use a TableViewController
you can still achieve this by adding your CustomView to the navigationController's
view
