を提示するときに制約の問題を理解しようとしていますUIAlertController。

2019-04-26 11：40：42.140007 + 0100 MyAPP [12811：3974220] [LayoutConstraints]制約を同時に満たすことができません。おそらく、次のリストの制約の少なくとも1つは不要なものです。これを試してください：（1）各制約を見て、予期しないものを見つけ出してください。（2）不要な制約を追加したコードを見つけて修正します。（ ""）制約を解除して回復を試みますUIViewAlertForUnsatisfiableConstraintsでシンボリックブレークポイントを作成して、デバッガーでこれをキャッチします。にリストされているUIViewのUIConstraintBasedLayoutDebuggingカテゴリのメソッドも役立つ場合があります。

UIAlertController以下の関数を使用して作成し、提示します

制約の問題はiPhoneXでのみ発生するようです。iPadとiPhone7および7plusでは問題は発生しません。

ありがとうございました。

iPadでも同様の問題が発生しました。

sourceRectを削除し、view.frameをCGRect（x、y、0、0）に変更する問題を修正しました。

では、moreActionsCellSheetController.popoverPresentationController?.sourceRectコードを削除するのはどうですか？

sourceRectは、UIAlertControllerの位置を意味します。ですから、CGRectのように設定したほうがいいと思います。

ありがとう。
