無法在本機中上傳/啟動圖片上傳器

Question

在開始顯示代碼之前，我想提到我正在使用iPhone模擬器。

所以，我正在瀏覽這個博客

像這樣添加了權限（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>

隨后按字面上復制並粘貼其代碼

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

現在，當我單擊選擇的照片時，它將帶我到Xcode屏幕，該屏幕將打開

有人可以幫助我弄清楚我該怎么做嗎？ 還是可以在模擬器上使用？

Answer 1

將函數名稱從handleChosePhoto更改為handleChoosePhoto
