全盲の妻の為に、補助的なキーボードアプリを製作中です。
普段はVoiceOverの音声読み上げを利用しています。
既存のキーボードには、メール作成時にカーソル移動ができなく、(3DTouchを使用すればできますが、あくまで晴眼者にしかできません)
Apple Storeに配布するつもりはなく、あくまで個人だけでの使用目的ですので、Macを購入してまでやるつもりはありません。
日々、悶々としています。
ここまでできましたが、最終段階のiPhoneグローブキーを作りたいと思っています。
(既存のキーボードと切り替えて使えるように)
そのボタンをどこに、どのように追加したらいいか判りません。
どなたかわかる方、教えて下さい。
