Question

我正在尝试使用提供的钩子useActionSheet（）在功能组件中使用https://github.com/expo/react-native-action-sheet。我已经在使用类组件版本，没有任何问题，但是我想切换到功能。

实际版本为16.9.0

这是我的组成部分

  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);

单击按钮时，预计会记录“测试-现在选择操作”这句话，但没有其他反应。操作表无法打开。

即使在使用钩子时，也要检查您是否使用 <ActionSheetProvider /> 包裹了顶级组件
