layoutSubviews メソッドで iPad の向きに基づいてサブビューを再配置する UIView があります。layoutSubviews メソッド内に、サブビューの再配置をアニメーション化することになっている CABasicAniamtion があります。アニメーションは特定の期間に設定されていますが、この期間は無視され、再配置がすぐに行われます。AnimationDidStart メソッドと AnimationDidStop メソッドが起動しているので、アニメーションが起動していることがわかります。これはUIViewのCALayersと関係があることは知っていますが、これを修正する方法を説明するためにウェブ上で何も見つけることができません. どんな助けでも大歓迎です。
