在反应导航 5.x 上动态更改标题标题

问题描述：

我最近更新了我的项目以响应导航 5.x.在早期版本中，我们使用如下设置标题标题:

I have recently updated my project to react navigation 5.x. In earlier version we used to set header title as follows :

static navigationOptions = ({ navigation }) => ({
        title: 'find',
});

这不适用于 React Navigation 5.x.请提出建议.

答

你可以通过 2 种方法来解决；

You can do it via 2 methods;

1:将 options 设置为屏幕上的变量并保留当前代码:

1: Set options to be a variable from your screen and keep your current code:

<Stack.Screen
  name="Label"
  component={Component}
  options={Component.navigationOptions}
/>

// component
static navigationOptions = {
  title: 'find',
};

2:通过在组件中使用 setOptions:

2: By using setOptions in your component:

<Stack.Screen
  name="News"
  component={News}
  options={{
    title: 'Default',
  }}
/>

// component
this.props.navigation.setOptions({title: 'find'});
