[iOS] Predictions are not updated when using navigation buttons

[Enrica Casucci]

Predictions on top of the on screen keyboard are not updated when changing focus using the navigation buttons.
We need to notify the keyboard that the selection has changed so that it can update the prediction bar.

We normally don’t use dot syntax after get(), but instead prefer bracket syntax in this case.

I’m assuming it’s OK to call -buttonItems here without a runtime check, because this method will only be called if -buttonItems is defined. If I’m wrong, please add a -respondsToSelector check.

Yes, it is OK.
