私のアプリからメッセージを送信したい - ユーザーが画面を中止して右上の「キャンセル」をクリックするとアプリが黒くなり、クラッシュします。メッセージフォームのキャンセル後にクラッシュする
私はそれがビューとは関係があると思うので、App Viewは戻ってこないのですが、どのように、なぜ、私はわかりません。私はブレークポイントを作ったが、これらの前にアプリがクラッシュする。ここで
は、この全体のコードです:

ではなく、UIViewControllerにMFMailComposeViewControllerDelegateを移動しようとしましたが、失敗しました...私はsendSMSとsendEmail funcも移動する必要がありますか?申し訳ありませんが、私はそれを取得しません:/ –
はいセルはこれらのアクションの責任を負いません、セルは、ボタンが押された委任を使用しての通知を送信する必要があります。次に、viewControllerは残りの処理を行う必要があります。 – PoolHallJunkie
