In IOS keyboards there is a globe button that if held will show a pop-up list of keyboards that the user can switch too.
However in the KeyboardViewController class, the only method I see to make a keyboard switch button is the
self.advanceToNextInputMode()
The problem with this is that while it allows you to create a button that if clicked will switch keyboards this method does not allow you to create a button that if you press and hold will show the list of currently enabled keyboards that the user can switch to by moving their finger to the correct entry.
How can I mimic the default IOS globe keyboard button behavior?
