我有一个UIBezierPath,我想得到它的镜像.我该如何做到这一点？
@H_404_2@// Method for generating a path
UIBezierPath *myPath = [self generateAPathInBounds:boundingRect];
// ? now I would like to mirror myPath ?
解决方法
@H_404_2@// Method for generating a path
UIBezierPath *myPath = [self generateAPathInBounds:boundingRect];
// Create two transforms,one to mirror across the x axis,and one to
// to translate the resulting path back into the desired boundingRect
CGAffineTransform mirrorOverXOrigin = CGAffineTransformMakeScale(-1.0f,1.0f);
CGAffineTransform translate = CGAffineTransformMakeTranslation(boundingRect.width,0);
// Apply these transforms to the path
[myPath applyTransform:mirrorOverXOrigin];
[myPath applyTransform:translate];
