无法在本机中上传/启动图片上传器

Question

在开始显示代码之前，我想提到我正在使用iPhone模拟器。

所以，我正在浏览这个博客

像这样添加了权限（在我的info.plist中）

<key>NSPhotoLibraryUsageDescription</key>
<string>For choosing a photo.</string>
<key>NSCameraUsageDescription</key>
<string>For taking a photo.</string>
<key>NSPhotoLibraryAddUsageDescription</key>
<string>For saving a photo.</string>

随后按字面上复制并粘贴其代码

import React, { Component } from 'react'
import { 
  View,
  Image,
  Button,
  Text
 } from 'react-native'
import ImagePicker from 'react-native-image-picker'
class UserImage extends Component {

  state = {
    photo: null
  }

  handleChosePhoto = () => {
    const options = {
      noData: true
    }

    ImagePicker.launchImageLibrary(options, response => {
      if (response.uri) {
        this.setState({ photo: response });
      }
    });
  }

  render () {
    return (
      <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
      {this.state.photo && (
        <Image
          source={{ uri: photo.uri }}
          style={{ width: 300, height: 300 }}
        />
      )}
      <Button title="Choose Photo" onPress={this.handleChosePhoto} />
    </View>
    )
  }

}

export default UserImage

现在，当我单击选择的照片时，它将带我到Xcode屏幕，该屏幕将打开

有人可以帮助我弄清楚我该怎么做吗？ 还是可以在模拟器上使用？

Answer 1

将函数名称从handleChosePhoto更改为handleChoosePhoto
