Upon first use after installation, the user needs to copy a configuration from elsewhere, similar to **vless://id@ip:port?security=none&encryption=none&type=tcp**, then paste it from the clipboard or scan a QR code. The configuration will be saved to **UserDefaults**, allowing the user to simply click 连接 for subsequent uses. 8 | 9 | ## 地理文件 10 | 如果您的网络可以自由的访问github，那么可以直接点击**地理文件**下载，下载成功以后会显示在页面上。如果有限制，建议先连接vpn，之后再点击**地理文件**下载 11 | 12 | If your network can freely access GitHub, you can directly click **地理文件** to download them. Once downloaded successfully, they will be displayed on the page. If there are restrictions, it is recommended to first connect to a VPN and then click **地理文件** to download. 13 | 14 | ## LibXrayPing 15 | 启动**xray**以后，就不能使用**LibXrayPing**方法，所以连接中的时候隐藏了**点击获取网速** 16 | 17 | After starting **Xray**, the **LibXrayPing** method can no longer be used, so the **点击获取网速** text is hidden while the VPN is connected. 18 | 19 | ## 测试机型 20 | iphone 15 plus，系统 ios 17.6.1 和 18 21 | iphone 12，系统 ios 17.6.1 22 | 低于17.6.1的版本我没有测试过，很抱歉我就只有一台ios17.6.1的iphone 23 | I have not tested versions below 17.6.1.
