react-navigation 中的多tabs嵌套时内部tabs无法正常切换问题

const MyApp = TabNavigator({
  Home: {
    screen: MyHomeScreen,
  },
  ChildrenTabs: {
    screen: ChildrenTabsScreen,
  },
}, {

  //这里加两句设置，将切换动画和能否滑动设为false
  swipeEnabled:false,
  animationEnabled: false,
  //将这两个设置false后就不会产生父子tabs之间的冲突了

  tabBarOptions: {
    activeTintColor: '#e91e63',
  },
});
