反应本机导航标题隐藏

但是,LoginScene中的头集和ChattingScene中的头集都会显示。

在聊天中,使用静态导航选项使标题为空不会创建后退按钮。

我想解决这个问题。

导航器.js

const ChattingScene = createStackNavigator({
 Chatting: {screen: Chatting}
 ...
},
{
 headerMode: 'float'
})

const MainScene = createStackNavigator({
 MainTab: {screen: MainTab},
 ChattingScene: {screen: ChattingScene}
},
{
 headerMode: 'none'
})

const SignUpScene = createStackNavigator({
 SignUp: {screen: SignUp},
 PWDSearch: {screen: PWDSearch},
},
{
 headerMode: 'none'
})

const LoginScene = createStackNavigator({
 LoginUI: {screen: LoginUI},
 SignUpScene: {screen: SignUpScene},
 MainScene: {screen: MainScene},
},
{
 initialRoutName: 'LoginUI',
 headerMode: 'float',
})

const HomeScene = createStackNavigator({
 LoginScene: {screen: LoginScene}
},
{
 headerMode: 'none'
})

export default class Navigator extends Component {
 render() {
  return(
   <HomeScene />
  );
 }
}
