   ###解决方法：手动设置IP
   
   - RCTBundleURLProvider在接口中暴露了jsLocation属性，可以通过setJsLocation手动设置IP。
  
    <span>
    ```
      NSURL *jsCodeLocation;

      [[RCTBundleURLProvider sharedSettings] setDefaults];
      #if DEBUG
      [[RCTBundleURLProvider sharedSettings] setJsLocation:@"192.168.1.101"];
      #endif
      jsCodeLocation = [[RCTBundleURLProvider sharedSettings]     
      jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];

</span>
