如何使用 react-native-camera 的 refreshAuthorizationStatus 函数

Question

我想使用函数 refreshAuthorizationStatus，来自 here

而且我还希望在未授予权限时进行回调。谁能帮我这个？我还没有找到如何调用此函数的示例。我在我的本机反应项目中为我的相机设置了以下设置：

      <RNCamera
            ref={ref => {
                this.camera = ref;
            }}
            orientation='portrait'
            captureAudio={false}
            type={RNCamera.Constants.Type.front}
            flashMode={RNCamera.Constants.FlashMode.off}
            androidCameraPermissionOptions={{
                title: 'Permission to use camera',
                message: 'We need your permission to use your camera',
                buttonPositive: 'Ok',
                buttonNegative: 'Cancel',
            }}
            androidRecordAudioPermissionOptions={{
                title: 'Permission to use audio recording',
                message: 'We need your permission to use your audio',
                buttonPositive: 'Ok',
                buttonNegative: 'Cancel',
            }}
            style={styles.camera}>

            <TouchableOpacity onPress={this.takePicture.bind(this)}></TouchableOpacity>
      </RNCamera>

通过以下方式授予的权限：等待 this.camera.refreshAuthorizationStatus()，this.camera 是一个引用集，

this.camera.refreshAuthorizationStatus().then(() => {
 // 
}).catch((e) =>{
// 
}):
