Javascript React Native/Redux：为什么即使使用水平动画推送路线，也会使用垂直过渡动画弹出路线？

在React Native+Redux中，我可以根据路线动态更改过渡动画的

方向属性，只要
方向：
属性为define:

this.props.navigation.routes[this.props.navigation.index].方向

例如，我已经定义了
方向：
被推为
垂直
，但是当弹出时，带有
水平
过渡动画的路径
应该是推送方向：
的路径，在本例中为
水平
。可能是什么问题

提前感谢您：

这是我的设置-

我的减速器（
navReducer.js

这些方法处理按下和弹出以及导航栏后退（pop）按钮的设置方式：
