テストモードで商品を購入する際に問題が発生します。私は2つのビューコントローラーを持っています。 viewcontroller2はIAPクラスです。コインを買うことはうまく動作し、そのディスプレイはビューコントローラ1にあるラベルにコインを完璧に買った。だから、私がviewcontroller1（コインを使う場所）に切り替えて、viewcontroller2に戻り、コインを買うために買いボタンをもう一度押すとクラッシュします。ViewController respondsToSelector：消耗品の購入中に割り当て解除されたインスタンスにメッセージが送信される
viewcontroller2：あなたはそのエラーを調査するために楽器を使用することができます
