如何将子视图旋转x度? [英] How do I rotate a subview x degrees?

问题描述

所以我想将子视图旋转x度(或至少90度).我希望子视图围绕子视图的右下角旋转.是否可以像下面的图片那样对此进行动画处理?

So I want to rotate a subview x degrees (or at least 90 degrees). I want the subwiew to rotate around the subview's bottom right corner. Is it possible to do this animated like in the picture below?

谢谢！
