ios - 无法在 native iOS 中读取未定义的属性 showImagePicker

Question

我已经厌倦了这个问题

1. npm install react-native-image-picker@latest --save
2. react-native 链接 react-native-image-picker

从“react-native-image-picker”导入 ImagePicker；

const options = {
      quality: 1.0,
      maxWidth: 500,
      maxHeight: 500,
      storageOptions: {
        skipBackup: true
      }
    };


    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 {
          const source = { uri: response.uri };

          // You can also display the image using data:
          // const source = { uri: 'data:image/jpeg;base64,' + response.data };

          this.setState({
            avatarSource: source,
          });
        }
      });[enter image description here][1]

每次运行 link 命令都需要重启 packager 才能生效。只需取消正在运行的 packager 并再次运行 react-native run-ios
