iOS Keyboard extension: able to display key tap beyond keyboard field?

I am working on a iOS Keyboard extension app, where similar to the aesthetic of the default keyboard, a zoom-in view of the key appears to confirm to the user which key they have just tapped on.

This works well for lower row keys such as "Z":

However, when it comes to top row keys, I find that I am unable to go beyond the view space of the keyboard, so that taps look like the following:

I was wondering if anyone has found a workaround to this, so that the keys could actually display over the app in which the keyboard extension is active? Thanks!

Solution

  • No, you can't draw outside the keyboard window.

    If you look at the view hierarchy you can see that the custom keyboard is in a separate UIWindow and it's bounds prevent you from drawing above the top of the keyboard.
