部分代码如下：
export const AppTabNavigator = createBottomTabNavigator({
Home:{
screen:HomePage,
navigationOptions: ({navigation})=>({
tabBarLabel:‘首页’,
tabBarIcon:({tintColor,focused})=>(
<TabBarItem
tintColor={tintColor}
focused={focused}
normalImage={require(’…/res/images/ic_trending.png’)}
selectedImage={require(’…/res/images/ic_trending.png’)}
/>
)
})
},
})
export const AppStackNavigator = createStackNavigator({
HomePage:{
screen:HomePage,
navigationOptions:{
headerTitle:“首页”
}
},})
