reactjs - 是否可以使用带有React-Navigation(v5)的UIModalPresentationPageSheet或UIModalPresentationFormSheet样式来呈现模态？

Question

根据Apple documentation的说法，在iOS 13上呈现模式默认为UIModalPresentationAutomatic，它通常映射到UIModalPresentationPageSheet样式。

同样，react-native-screens appears to support有各种选项，但是到目前为止，我还无法确定是否可以通过react-navigation传递它，或者react-navigation是否正在使用此代码路径。 react-native-screens appears to default到UIModalPresentationAutomatic，这使我相信react-navigation完全在做其他事情。

是否可以在Stack.Screen中使用这些较小的模式类型来呈现这些Stack.Navigator组件？

这是一个演示该问题的简单React Native应用。

import "react-native-gesture-handler"
import * as React from "react"
import { Button, View, Text } from "react-native"
import { NavigationContainer } from "@react-navigation/native"
import { createStackNavigator } from "@react-navigation/stack"
function HomeScreen({ navigation }) {
  return (
    <View style={{ flex: 1, alignItems: "center", justifyContent: "center" }}>
      <Text>Home Screen</Text>
      <Button
        title="Go to Details"
        onPress={() => navigation.navigate("Details")}
      />
    </View>
  )
}

function DetailsScreen() {
  return (
    <View style={{ flex: 1, alignItems: "center", justifyContent: "center" }}>
      <Text>Details Screen</Text>
    </View>
  )
}

const Stack = createStackNavigator()

function App() {
  return (
    <NavigationContainer>
      <Stack.Navigator
        mode="modal"
        initialRouteName="Home"
        screenOptions={{
          stackPresentation: "formSheet",
        }}
      >
        <Stack.Screen name="Home" component={HomeScreen} />
        <Stack.Screen name="Details" component={DetailsScreen} />
      </Stack.Navigator>
    </NavigationContainer>
  )
}

export default App

不管指定的 stackPresentation如何，它始终以全屏模式显示。如何获得 UIModalPresentationFormSheet行为？

Answer 1

您“只是”需要直接从createNativeStackNavigator使用react-native-screens函数。 react-navigation docs实际上有一段描述如何设置它。
对于上面的示例应用程序，您只需要导入所需的两个函数并更改堆栈初始化，如下所示

import { createNativeStackNavigator } from 'react-native-screens/native-stack'
import { enableScreens } from 'react-native-screens'

enableScreens()
const Stack = createNativeStackNavigator()

然后在 screenOptions组件中设置适当的 Stack.Navigator。

<Stack.Navigator
  initialRouteName="Home"
  screenOptions={{ 
    headerShown: false, 
    stackPresentation: 'formSheet' 
  }}
