reactnative createbottomtabnavigator 隐藏标签栏标签

我需要知道如何隐藏底部标签.

我试过以下方法:

tabBarShowLabels:'隐藏'，tabbarlabelvisible:错误.

我还删除了tabbarlabel: 'Home'，它仍然显示

如果有人能给我指出正确的方向，我将不胜感激.

import {createBottomTabNavigator} from 'react-navigation'
import Icon from 'react-native-vector-icons/Ionicons'


const Tabs = createBottomTabNavigator ({
  Home:{
    screen: Home,
    navigationOptions:{
      tabBarIcon: ({ focused, tintcolor }) => (
        <Icon name="ios-home" size={24}  />
      )
    }
  },
  Inbox:{screen: Inbox,
    navigationOptions:{
      tabBarIcon: ({ tintcolor }) => (
        <Icon name="ios-mail" size={24} />
      )
    }
  },
  Search:{screen: Search,
    navigationOptions:{
      tabBarIcon: ({ tintcolor }) => (
        <Icon name="ios-search" size={24} />
      )
    }
  },
  Favorites:{screen: Favorites,
    navigationOptions:{ 
    tabBarIcon: ({ tintcolor }) => (
      <Icon name="ios-heart" size={24} />
    )
  }
  },
  Settings:{screen: Settings,
    navigationOptions:{ 
      tabBarIcon: ({ tintcolor }) => (
        <Icon name="ios-settings" size={24} />
      )
    }
  }

}
});



export default class App extends Component {
  render() {

    return <Tabs />
  }
}
