React Navigation V2：navigation.push 和 navigation.navigate 之间的区别

React Navigation是一个用于React Native应用程序的流行导航库。它提供了一种简洁、灵活的方式来管理应用程序的导航。在React Navigation V2中，我们有两个常用的导航方法，即navigation.push和navigation.navigate。尽管它们在功能上非常相似，但它们之间存在一些细微的差别。

javascript
import React from 'react';
import { Button } from 'react-native';
import { createStackNavigator } from 'react-navigation';
class HomeScreen extends React.Component {
  render() {
    const { navigation } = this.props;
    return (
              title="Go to Details"
        onPress={() => navigation.push('Details')}
      />
    );
  }
}
const AppNavigator = createStackNavigator({
  Home: HomeScreen,
  Details: DetailsScreen,
});
export default createAppContainer(AppNavigator);

javascript
import React from 'react';
import { Button } from 'react-native';
import { createStackNavigator } from 'react-navigation';
class DetailsScreen extends React.Component {
  render() {
    const { navigation } = this.props;
    return (
              title="Go back"
        onPress={() => navigation.navigate('Home')}
      />
    );
  }
}
const AppNavigator = createStackNavigator({
  Home: HomeScreen,
  Details: DetailsScreen,
});
export default createAppContainer(AppNavigator);
