React Native Image Picker无法读取未定义的属性“ showImagePicker”

[英]React Native Image Picker cannot read property “showImagePicker” of undefined

我已经按照所有iOS的安装说明进行了包装react-native-image-picker showImagePicker() ,但是在我尝试使用showImagePicker()方法时,它仍然会出错。

它告诉我它cannot read property "showImagePicker" of undefined

我在文件顶部导入了包var ImagePicker = require('react-native-image-picker'); ,我已多次进行react-native link ,已将RNImagePicker.xcodeproj添加到我的库文件夹,已将RNImagePicker.a添加到“使用库链接二进制文件”,已将权限添加到我的info.plist文件。

我已经完成了文档中的所有操作,但是仍然没有任何效果。

这是我的JS:

import React from 'react';
import PropTypes from 'prop-types';
import { StyleSheet, Text, View, Image, ScrollView, TextInput, TouchableOpacity, KeyboardAvoidingView } from 'react-native';

var ImagePicker = require('react-native-image-picker');

export default class ProfilePicUploaderPage extends React.Component {
  state = {
    ProfilePicLocalSource: null,
    ProfilePicRemoteSource: null
  }

  ChoosePhoto(){
    console.log(SOCButton);
    var options = {
      title: 'Select Avatar',
      customButtons: [
        {name: 'fb', title: 'Choose Photo from Facebook'},
      ],
      storageOptions: {
        skipBackup: true,
        path: 'images'
      }
    };
    ImagePicker.showImagePicker(options, (response) => {
      console.log('Response = ', response);

      if (response.didCancel) {
        console.log('User cancelled image picker');
      }
      else if (response.error) {
        console.log('ImagePicker Error: ', response.error);
      }
      else if (response.customButton) {
        console.log('User tapped custom button: ', response.customButton);
      }
      else {
        let source = { uri: response.uri };

        this.setState({
          avatarSource: source
        });
      }
    });


  }

  render(){
      return(<all of my JSX>);
  }

关于发生的事情,我的唯一线索是,当我尝试在Xcode中构建我的应用程序时,它失败并显示错误clang: error: linker command failed with exit code 1 (use -v to see invocation)

有人知道发生了什么吗?

您似乎没有将ImagePicker导入到JS文件中。 尝试import ImagePicker from 'react-native-image-picker'使用import ImagePicker from 'react-native-image-picker'

如果您正确地遵循了iOS的链接步骤,那就应该不错了。
