如何隐藏React Native NavigationBar [英] How to hide React Native NavigationBar

问题描述

我在Navigator下有NavigatorIOS，并想隐藏Navigator的NavigationBar以使用NavigatorIOS的栏.有什么办法吗?

I have NavigatorIOS under Navigator and would like to hide Navigator's NavigationBar to use NavigatorIOS's bar. Is there any way to do this?

这是

This is screenshot that I've seen. I need backend of NavigatorIOS..

我要构建的结构如下:

├── NavigatorRoute1
│   ├── NavigatorIOSRoute1
│   ├── NavigatorIOSRoute2
│   └── NavigatorIOSRoute3
└── NavigatorRoute2

我的代码如下. (基本上从UIExplore示例获得.

The code that I have is the below. (Basically obtained from UIExplore examples.

render: function(){
return (
  <Navigator
    initialRoute={ROUTE_STACK[this.getInitialRouteIndex()]}
    initialRouteStack={ROUTE_STACK}
    style={styles.container}
    renderScene={this.renderScene}
    navigationBar={
      <Navigator.NavigationBar
        routeMapper={NavigationBarRouteMapper}
        style={styles.navBar}
      />
    }
  />
);
}

NavigatorIOS

render: function(){
var nav = this.props.navigator;
 return (
  <NavigatorIOS
    style={styles.container}
    ref="nav"
    initialRoute={{
      component: UserSetting,
      rightButtonTitle: 'Done',
      title: 'My View Title',
      passProps: {nav: nav},
    }}
    tintColor="#FFFFFF"
    barTintColor="#183E63"
    titleTextColor="#FFFFFF"
  />
);

}

我添加了一个更改状态的功能，该功能处理Navigator的渲染，并将prop传递给组件以更改状态.

I added a function to change state that handle rendering of Navigator and pass the prop to the component to change the state.

hideNavBar: function(){
  this.setState({hideNavBar: true});
},
render: function(){
 if ( this.state.hideNavBar === true ) {
  return (
    <Navigator
      initialRoute={ROUTE_STACK[0]}
      initialRouteStack={ROUTE_STACK}
      renderScene={this.renderScene}
    />
  );
 }else{
  return (
    <Navigator
      initialRoute={ROUTE_STACK[this.getInitialRouteIndex()]}
      initialRouteStack={ROUTE_STACK}
      style={styles.container}
      renderScene={this.renderScene}
      navigationBar={
        <Navigator.NavigationBar
          routeMapper={NavigationBarRouteMapper}
          style={styles.navBar}
        />
      }
    />
  );
}

}

和

render: function(){
 var hideNavBar = this.props.hideNavBar;
 return (
  <NavigatorIOS
    style={styles.container}
    initialRoute={{
      component: UserSetting,
      rightButtonTitle: 'Done',
      title: 'My View Title',
      passProps: {hideNavBar: hideNavBar},
    }}
    tintColor="#FFFFFF"
    barTintColor="#183E63"
    titleTextColor="#FFFFFF"
  />
 );

}

推荐答案

在您的Navigator类中，您好像正在传递导航栏.您可以在其中添加逻辑，以根据想要使用的方式传递到Navigator.NavigationBar或NavigatorIOS栏中.为此，您需要在导航器中指定要更改栏的状态变量.

In your Navigator class it looks like you're passing in a navigation bar. You can add logic there to pass in either Navigator.NavigationBar or your NavigatorIOS bar depending on which you'd like to use. To do that you'd need to specify a state variable in Navigator that you'd update when you want the bar to change.
