如何解决React Native项目中的权限被拒绝问题？

import { PermissionsAndroid, Alert } from 'react-native';
import { request, PERMISSIONS } from 'react-native-permissions';

const requestCameraPermission = async () => {
  try {
    const granted = await request(PERMISSIONS.ANDROID.CAMERA);
    if (granted === 'granted') {
      console.log('Camera permission granted');
    } else {
      Alert.alert('Camera Permission Denied', 'You need to give camera permission to use this app.');
    }
  } catch (err) {
    console.warn(err);
  }
};

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

const checkCameraPermission = async () => {
  try {
    const granted = await PermissionsAndroid.check(PERMISSIONS.ANDROID.CAMERA);
    if (!granted) {
      requestCameraPermission();
    }
  } catch (err) {
    console.warn(err);
  }
};

<key>NSCameraUsageDescription</key>
<string>This app requires access to the camera.</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>This app requires access to the photo library.</string>

const requestCameraPermission = async () => {
  try {
    const granted = await request(PERMISSIONS.ANDROID.CAMERA);
    console.log('Camera permission result:', granted);
    if (granted === 'granted') {
      console.log('Camera permission granted');
    } else {
      Alert.alert('Camera Permission Denied', 'You need to give camera permission to use this app.');
    }
  } catch (err) {
    console.error('Camera permission error:', err);
  }
};
