objective-c - ios 关于视图变大后子视图的问题

Question

如题
是这样的 比如我有一个uiview 上面有一个UIimageview和UIlabel 当我用[UIView animateWithDuration:0.2 animations:^{}];这个动画函数 将UIview变大 但是发现上面的UIimageview和UIlabel的视图并没有跟随变大，是不是只有取到UIview的子视图UIimageview和UIlabel做操作让其变大 这样的话就太麻烦了 比如 我UIview的子视图很多 那不是操作就更多了，有没有什么办法是只需要改变UIview的大小其他的子视图跟随变大的办法呢？

Just use the simplest scale transformation.

CABasicAnimation *animation = [CABasicAnimation animationWithKeyPath:@"transform.scale"];
animation.fromValue = @(1.0);
animation.toValue = @(2.0);
animation.duration = 2.0f;
animation.repeatCount = 1;
[self.button.layer addAnimation:animation forKey:@"ScaleAnimation"];

If you usually use pop, this is it:

POPBasicAnimation *animation = [POPBasicAnimation animationWithPropertyNamed:kPOPViewScaleXY];
animation.toValue = [NSValue valueWithCGPoint:CGPointMake(2.0, 2.0)];
animation.duration = 3.0f;
[self.button pop_addAnimation:animation forKey:@"ScaleAnimation"];

Answer 3

If you use automatic layout, set the distance from the child control to the parent control and call LayoutIfNeed to re-layout

Answer 4

There is no such function
