我想一次应用缩放和旋转。问题是当我这样做时旋转是正确的,但缩放会减小。我分别测试比例和旋转,它工作得很好。以下是我的代码
CGAffineTransform transformScale = CGAffineTransformMakeScale( tmp.size, tmp.size);
CGAffineTransform transformRotate = CGAffineTransformMakeRotation((CGFloat)tmp.rotation);
[iview setTransform:CGAffineTransformConcat(transformScale, transformRotate)];
