ios predictive text hides input field

I have an input field at the bottom of the screen, when I click the text field to edit it, the keyboard comes up and hides the input field so I can not see what I am typing. Is this a bug or is there a setting to stop this?
This is only on the edit, the initial data entry they keyboard comes up and you can see the text input field.

I also note from the documentation that there is a xojo.ioskeyboardtype although the compiler throws an error if I try to change it.
