我创建了一个像这样的底部导航器:
const IOSTabs = createBottomTabNavigator(
{
Home: {
screen: HomeScreen,
navigationOptions: {
headerStyle: {backgroundColor: 'green'},
title: 'Home',
tabBarLabel: 'Homes',
tabBarIcon: <Icon name="home-outline" size={25}/>,
}
},
Settings: {
screen: SettingsScreen,
navigationOptions: {
tabBarIcon: <Icon name="settings-outline" size={25} />
}
}
}
);
const StackNavigator = createStackNavigator(
{
Home: IOSTabs
}
);
const AppNavigator = createAppContainer(StackNavigator);
export default {
components: { AppNavigator }
}
这很好用,虽然标题显示,但标题为空,无法向其添加按钮或文本。我认为title
应该显示标题,但事实并非如此。
我在这里想念什么?
