即使在React native中的iOS设备中权限被拒绝，我仍然能够从图片库获取图像

npm install react-native-image-picker

import ImagePicker from 'react-native-image-picker';

const selectImage = () => {
  ImagePicker.launchImageLibrary({}, (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 };
      // 处理获取到的图像
      console.log(source);
    }
  });
};

<Button title="选择图像" onPress={selectImage} />
