ios <Error>: CGAffineTransformInvert: singular matrix.

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);
