I now have a working iOS 8 Custom Keyboard to input Chinese, and I am looking for the possibility to use this keyboard with external bluetooth keyboard.
My first question is if anyone has successfully used external keyboard with custom keyboard? I am asking because when I connect my Apple wireless keyboard to my iPad Air, the software keyboard won't show up hence I have no way to tell which keyboard I am using. Also using command + space does not switch to my own keyboard.
I then tried to use external keyboard with built-in Chinese Zhuyin Keyboard and it doesn't work, it just outputs Zhuyin symbols but no Chinese words to select from.
I can understand that external keyboard won't work for custom keyboards because the custom keyboard keys must be somehow associated with the external keyboard keys. However, I think at least the built-in keyboard should work.
So my second question is if anyone has tried to use external bluetooth keyboard to input text using built-in keyboard other than English, preferably for languages that needs a mapping table(for example, Chinese and Japanese, you input some symbols and there should be a list of words that you can choose from).
