我正在尝试制作 UIView 动画，其中我的图像从屏幕的左上角开始并扩展到原始大小并放置在屏幕中间。到目前为止，我已经能够使其单独执行此操作，但是当我尝试组合这些动画时，它只会执行缩放动画。

有没有办法可以同时使用Scale 和 Translation来完成这项工作？

这是我到目前为止所拥有的：

CGAffineTransform setpointTrans = CGAffineTransformMakeTranslation(-200.0f, -200.0f);
CGAffineTransform setpointScale = CGAffineTransformMakeScale(0.0f, 0.0f);
_RSEImage.transform = CGAffineTransformConcat(setpointTrans, setpointScale);
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDelegate:self];
[UIView setAnimationDuration:5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseOut];
CGAffineTransform scaleTrans  = CGAffineTransformMakeScale(1.0f, 1.0f);
CGAffineTransform lefttorightTrans  = CGAffineTransformMakeTranslation(0.0f,0.0f);
_RSEImage.transform = CGAffineTransformConcat(scaleTrans, lefttorightTrans);
[UIView commitAnimations];

好的，我想通了，这是我更改的内容：

_RSEImage.transform = CGAffineTransformMakeScale(0.0f, 0.0f);
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDelegate:self];
[UIView setAnimationDuration:5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseOut];
CGAffineTransform scaleTrans  = CGAffineTransformMakeScale(1.0f, 1.0f);
CGAffineTransform lefttorightTrans  = CGAffineTransformMakeTranslation(200.0f,200.0f);
_RSEImage.transform = CGAffineTransformConcat(scaleTrans, lefttorightTrans);
[UIView commitAnimations];

您也可以使用这个动画块（来自 iOS4）：

[UIView animateWithDuration: 5
                      delay: 0
                    options: (UIViewAnimationOptionCurveLinear | UIViewAnimationOptionAllowUserInteraction)
                 animations:^{_RSEImage.center = CGPointMake(300, 300) ; _RSEImage.transform = CGAffineTransformScale(CGAffineTransformIdentity, 2.0, 2.0);}
                 completion:^(BOOL finished) { }
 ];
