I think this is the issue related to iOS 7.1 because our build was
working fine on iOS. One plain hack could be to use ionic keyboard plugin.
You see there are two events provided by this plugins
A number keyboardHeight is given on the event object, which
is the pixel height of the keyboard.
keyboardHeight is sent whenever keyboard appears. You can use this
height to resize your main content.
I know this is poor way of solving this issue but it can solve your
problem until this issue is solved in framework.
