React Native 64.0.3使用react-native-wifi-reborn无法检测SSID求助

先修复Info.plist的配置错误 #

你的Info.plist存在多处拼写和语法错误，这是权限申请失败的核心原因之一，修正后的配置如下：

<key>NSLocationAlwaysAndWhenInUseUsageDescription</key>
<string>The App uses the location for the network SSID</string>
<key>NSLocationAlwaysUsageDescription</key>
<string>The App uses the location for the network SSID</string>
<key>NSLocationTemporaryUsageDescriptionDictionary</key>
<dict>
  <key>SSID-Purpose</key>
  <string>The App uses the location for the network SSID</string>
</dict>
<key>NSLocationWhenInUseUsageDescription</key>
<string>The App uses the location for the network SSID</string>

错误说明： #

• 拼写错误：NSLocationAlwaysAndwhenInUseUsageDescription中的when需大写为When
• 标签闭合错误：多处将<string>错误写成</strings，且NSLocationTemporaryUsageDescriptionDictionary对应的类型应为<dict>而非<string>，注释里的</dicts也需改为</dict>

额外必要配置与检查 #

• 开启精确定位权限：iOS 13及以上版本获取WiFi SSID需要精确位置权限，在Info.plist中添加：

<key>NSLocationDefaultAccuracyReduced</key>
<false/>

• 代码中先请求定位权限：调用getSSID前必须先获取定位权限，示例代码：

import { PermissionsAndroid, Platform } from 'react-native';
import WifiManager from 'react-native-wifi-reborn';

const requestLocationPermission = async () => {
  if (Platform.OS === 'ios') {
    return true; // iOS会自动触发权限弹窗，也可使用权限库处理
  } else {
    const granted = await PermissionsAndroid.request(
      PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION,
      {
        title: "Location Permission",
        message: "App needs access to your location to get WiFi SSID",
        buttonNeutral: "Ask Me Later",
        buttonNegative: "Cancel",
        buttonPositive: "OK"
      }
    );
    return granted === PermissionsAndroid.RESULTS.GRANTED;
  }
};

// 获取SSID示例
const getCurrentSSID = async () => {
  const hasPermission = await requestLocationPermission();
  if (hasPermission) {
    try {
      const ssid = await WifiManager.getCurrentWifiSSID();
      console.log('Current SSID:', ssid);
    } catch (error) {
      console.error('Failed to get SSID:', error);
    }
  } else {
    console.log('Location permission denied');
  }
};

• 检查依赖版本兼容性：确保react-native-wifi-reborn适配RN64.0.3，建议安装^4.7.0版本：

npm install react-native-wifi-reborn@4.7.0 --save
# 或
yarn add react-native-wifi-reborn@4.7.0

• 重新编译项目：修改配置和依赖后，清理缓存并重新编译：

cd ios && pod install && cd ..
npx react-native run-ios --clean
