我有一个UIBezierPath,我想得到它的镜像.我该如何做到这一点？
@H_403_5@解决方法
// Method for generating a path UIBezierPath *myPath = [self generateAPathInBounds:boundingRect]; // ? now I would like to mirror myPath ?
// 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];
