CGAffineTransform不能正常工作

Question

我想让我的变换在平移图像的同时缩放图像，可以用同样的方法吗？

    [UIView beginAnimations:annKey context:NULL];
    [UIView setAnimationDelegate:self];
    [UIView setAnimationDuration:duration];
    [UIView setAnimationCurve:curve];
    [UIView setAnimationBeginsFromCurrentState:YES];
    [UIView setAnimationDidStopSelector:@selector(animationFinished:finished:context:)];
    CGAffineTransform transform = CGAffineTransformMakeTranslation(x, y);
    CGAffineTransform scale = CGAffineTransformMakeScale(xx, yy);
    image.transform = scale;
    image.transform = transform;
    [UIView commitAnimations];

您必须使用CGAffineTransformConcat将这两个转换连接在一起，以转换和缩放视图。您当前只是将比例变换替换为平移。
