如果你尝试，并设置缩放比例为零，你会得到这个消息：<Error>: CGAffineTransformInvert: singular matrix.
[UIView animateWithDuration:0.5 animations:^{
CGAffineTransform newTransform = CGAffineTransformScale(myView, 0.0, 0.0);
[myView setTransform:newTransform];
} completion:^(BOOL finished) {
}];
改为：CGAffineTransform newTransform = CGAffineTransformScale(s.transform, 0.0001f, 0.00001f);
