Unity の Performance Reporting は例外データを見つけて集め、ランタイムに何が発生しているかを理解するのに役立ち、プロジェクトをより早く最適化します。例外はゲームが完成したビルドとして実行されている間やエディターで再生モードの間に Services Dashboard に更新されます。
iOS crash reporting is available to Unity Plus and Pro users as part of the Unity Performance Reporting service. Turn on Performance Reporting to track crashes on iOS, including crashes in native user code, engine code, and plug-ins.
Performance Reporting の設定 に関する詳細は、Unity のドキュメントを参照してください。
IL2CPP を使用し、iOS Player Settings の Script Call Optimization を Fast but no exceptions に設定すると、iOS クラッシュレポートは、キャッチされないマネージ例外によるクラッシュを見つけます。
See documentation on iPhone Optimization for more information on the Script Call Optimization settings.
レポートにはクラッシュしたスレッドのネイティブスタックトレースが表示されます。クラッシュがキャッチされないマネージ例外によって発生した場合、レポートには、ネイティブスタックトレースとともに、例外の発生元のマネージスタックトレースも表示されます。
iOS クラッシュレポートでは、アプリケーションがメモリ不足になり、オペレーティングシステムによって閉じられたことによるクラッシュを捉えることはできません。
Unity Cloud Developer Dashboard にクラッシュが表示されます。ここでゲームを選択し、 Enable Game Performance (図 A) を選択します。
以下は、マネージ例外によるクラッシュのレポート例を表示ます。
