CGAffineTransform 无法正常工作

Question

我希望我的变换在翻译时缩放图像，是否可以使用相同的方法？

    [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 连接两个转换来翻译和 缩放您的视图。您目前只是用平移替换比例变换。
