如何使用帶鈎子的 react-native-action-sheet

Question

我正在嘗試使用提供的鈎子 useActionSheet() 在功能組件中使用https://github.com/expo/react-native-action-sheet 。 我已經在使用 class 組件版本，沒有任何問題，但我想切換到功能版本。

反應版本是 16.9.0

這是我的組件

import {
  connectActionSheet,
  useActionSheet,
} from "@expo/react-native-action-sheet";
import React, { Component } from "react";
import { View, Text, SafeAreaView } from "react-native";
import TaButton from "../components/TaButton";
import { typography, styles, buttons } from "../components/Styles";

const UploadUI: React.FC<{
  description: string;
  label: string;
}> = (props) => {
  const { showActionSheetWithOptions } = useActionSheet();

  const openActionSheet = () => {
    console.log("TEST - Choosing action now");
    const options = [
      "Scegli dalla libreria",
      "Scatta una foto",
      "Carica un file",
      "Annulla",
    ];
    //const destructiveButtonIndex = 0;
    const cancelButtonIndex = options.length - 1;

    showActionSheetWithOptions(
      {
        options,
        cancelButtonIndex,
        //destructiveButtonIndex,
      },
      (buttonIndex) => {
        // Do something here depending on the button index selected
        switch (buttonIndex) {
          case 0:
            console.log('Case 0')
            
            return;
          case 1:
            console.log("Case 1");
            return;
          case 2:
            console.log("Case 2");
            return;

          default:
        }
      }
    );
  };

  const { description, label } = props;
  return (
    <View style={{ flexDirection: "row", height: 50, marginBottom: 30 }}>
      <View style={{ flex: 0.7, justifyContent: "center" }}>
        <Text style={typography.body}>{description}</Text>
      </View>
      <View style={{ flex: 0.3 }}>
        <TaButton
          style={buttons.primary}
          labelStyle={buttons.primaryLabel}
          onPress={() => openActionSheet()}
          label={label}
        />
      </View>
    </View>
  );
};

const URWStep4: React.FC = (props) => {
  return (
    <SafeAreaView style={styles.container}>
      <View style={styles.container}>
        <View style={{ paddingVertical: 30, marginBottom: 20 }}>
          <Text style={typography.title}>
            Ci serviranno alcuni documenti per verificare la tua identità
          </Text>
        </View>
        <UploadUI
          description="Carta d'identità - Fronte"
          label="Carica"
        ></UploadUI>
        <UploadUI
          description="Carta d'identità - Retro"
          label="Carica"
        ></UploadUI>
      </View>
    </SafeAreaView>
  );
};

export default connectActionSheet(URWStep4);

當點擊按鈕時，“TEST - Choosing action now”這句話被記錄為預期的廣告，但沒有更多的反應。 操作表不會打開。

檢查您是否使用<ActionSheetProvider />包裝了頂級組件，即使使用鈎子也是如此

使用 useRef，我在 lib 和Allanmaral 的回答中看到了這個問題：

 import ActionSheet from 'react-native-actionsheet' const Demo = (props) => { const refActionSheet = useRef(null); showActionSheet = () => { if (refActionSheet.current) { refActionSheet.current.show(); } } return ( <View> <Text onPress={this.showActionSheet}>Open ActionSheet</Text> <ActionSheet ref={refActionSheet} title={'Which one do you like?'} options={['Apple', 'Banana', 'cancel']} cancelButtonIndex={2} destructiveButtonIndex={1} onPress={(index) => { /* do something */ }} /> </View> ) }
