DrawerView 侧边栏的问题

https://github.com/react-navigation/react-navigation/pull/793

写在StackNavigator里面
const Main = StackNavigator({
Tab: { screen: TabBar, navigationOptions: {drawerLockMode:'unlocked'},},
}, {
navigationOptions: {
header: null,
drawerLockMode:'locked-closed'
},
transitionConfig: () => ({
screenInterpolator: CardStackStyleInterpolator.forHorizontal
})
});
