ios CATransform3DMakeScale scaleup animation
提问by Juan
I have the following animation:
我有以下动画：
CATransform3D scaleTransform = CATransform3DMakeScale(0.1,0.1, 1.0);
scaleAnimation.toValue = [NSValue valueWithCATransform3D:scaleTransform];
keyframeAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseIn];;
where I'm scaling down a subview. But I'm trying to do opposite. start from .01% of the size of the subview and go to 100% of the size of the subview. Does anyone knows how can I do this?
我正在缩小子视图的位置。但我正试图做相反的事情。从子视图大小的 0.01% 开始，到子视图大小的 100%。有谁知道我该怎么做？

Do this:
做这个：
yourSubView.transform = CGAffineTransformMakeScale(0.01, 0.01);
[UIView animateWithDuration:0.4 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{
//change time duration according to requirement
// animate it to the identity transform (100% scale)
yourSubView.transform = CGAffineTransformIdentity;
} completion:^(BOOL finished){
// if you want to do something once the animation finishes, put it here
}];
