iOS如何翻转视图/图像并保持比例

Question

I can flip my view by doing something like this:

image.transform = CGAffineTransformMakeScale(-1, 1);

My problem is if I have scaled the item in the app this code obviously sends it back to its original size and flips it. How can I maintain the current scale and flip the object?

Answer 1

获取上下文的当前转换矩阵（CTM），并将翻转转换应用于该矩阵。
