Answer 1

私はあなたのオブジェクトまたはクラスの一つであると言うだろうオブザーバーをコアデータオブジェクトに登録するステップと、コアデータオブジェクト上のオブザーバを最初に登録解除することなく、観察クラス/オブジェクトがメモリから解放される。コアデータオブジェクトが更新されると、EXC_BAD_ACCESS/KERN_INVALID_ADDRESSを発生させる解放されたメモリブロックに通知が送信されます。

これをキャッチするには、ゾンビを有効にしてください（How to enable NSZombie in Xcode?を参照）。ゾンビはメモリ内の割り当て解除されたオブジェクトを保持しますが、ゾンビとしてマークします。したがって、プロセスがメモリから解放された後にプロセスにアクセスしようとすると、少なくともオブジェクトの詳細を取得できます。

幸運を祈る！
