javascript - React-Native 标签栏 : Remove horizontal line (React Native UI Kitten + React Navigation)

Question

在我在 iPhone 上运行的应用程序中使用 react-native-ui-kitten 组件 BottomNavigation 和 BottomNavigationTab (expo v2. 21.2, react-native v0.57.1​​ ), 当前选中的BottomNavigationTab 顶部有一条水平线，其中包含标题和图标。

来 self 的应用:

测试 B 选项卡已选中，图标上方有不需要的水平线。

来自文档:

BottomNavigation docs显示当标题和图标都被定义时，所选选项卡上没有水平线。但这对我来说不是这样。

问题:横线怎么去掉？

我的代码:

import { View } from 'react-native';
import { createBottomTabNavigator, createStackNavigator, createSwitchNavigator, createAppContainer } from 'react-navigation';
import { BottomNavigation, BottomNavigationTab, BottomNavigationProps, Avatar } from 'react-native-ui-kitten';

class BottomNavigationShowcase extends React.Component {

    ... 

    render () {
        return (
            <BottomNavigation
                selectedIndex={this.state.selectedIndex}
                onSelect={this.onTabSelect}
            >
                <BottomNavigationTab title='Test A' icon={this.renderIconA} />
                <BottomNavigationTab title='Test B' icon={this.renderIconB} />
                <BottomNavigationTab title='Test C' icon={this.renderIconC} />
                <BottomNavigationTab title='Test D' icon={this.renderIconD} />
            </BottomNavigation>
        );
    }

}

const TabNavigator = createBottomTabNavigator(
    {
        TestA: TestAScreen,
        TestB: TestBScreen,
        TestC: TestCScreen,
        TestD: TestDScreen
    }, {
        initialRouteName: 'TestA',
        tabBarComponent: BottomNavigationShowcase
    }
)

const RootNavigator = createSwitchNavigator({
    Main: TabNavigator,
}, {
    initialRoute: "Main"
})

只需尝试向 BottomNavigation 组件添加一个属性:appearance='noIndicator'。看起来我们忘记了在文档中显示此功能。希望这可以帮助。
