iphone - 画像を撮影し、UIImagePickerController で [USE] をタップすると、ランダムに黒い画面が表示される

Question

ほぼ完成したアプリがありますが、QA を行っているときに、QA エンジニアは、UIImagePickerControllerビューで [USE] をタップすると黒い画面が表示されるというランダムな問題に遭遇しました。さらにdidFinishPickingMediaWithInfo、画像は将来の参照用に保存されており、 に表示されてUIImageViewいます。ボタンを に追加するためにカメラ オーバーレイも使用しており、アプリの最大メモリ使用量は13 MBUIImagePickerViewを超えていません。キャプチャ モードからカメラ ロール モードに切り替えた場合、問題は発生しません。また、同じビューで提示されています。その下には、問題が関係している可能性のあるコードがあり、問題のアイデアを得るために画像も添付されています。どんな助けでも大歓迎です。iADs

前もって感謝します。
