TwitterおよびFacebookの[ツイート]または[共有]をクリックしたときに表示される「テキストボックス」。それらは何でできていますか？同様の何かを作ることができますか？tableViewの「コメント」として機能するようにカスタマイズしようとしています。私はこれらの2つのことについて話している：
「Tweet」や「Facebook」ではなく「Comment」と表示させようとしています。そして「Done」と表示され、「Send」と「Post」と表示されます。これらをどのように/どこで作成/カスタマイズできるかについてのアイデアはありますか？
これらはプライベートビューコントローラです。それらをカスタマイズすることはできません（まあ、そうすべきではありません）。自分で再実装する必要があります。
ただし、privateメソッド-recursiveDescriptionを使用して、ビュー階層がどのように構築されているかを知ることができます。を使用してテキストを共有するシンプルなアプリを作成しますUIActivityViewController。それを提示し、TwitterまたはFacebookを選択してから、デバッガーでアプリを一時停止します。コンソールに入力po [[[UIApplication sharedApplication] keyWindow] recursiveDescription]して、現在のビュー階層を一覧表示します。
