腾讯云 人脸核身 Flutter 插件功能开发(一 IOS 端实现)

前言

项目中需要使用到 腾讯云的人脸核身功能，但是官方没有提供对应的flutter plugin ，所以需要我们自己构建一个flutter plugin ，用于实现IOS 端人脸核身功能，plugin 插件地址github.com/qiangzengli…

  1. 进入官方网站，下载 SDK 工具包

  2. 创建 tencent_cloud_face_verify 插件

  3. 在Plugin 的 ios 目录中 创建Framework 文件夹，将第一步中SDK 中的 TencentCloudHuiyanSDKFace_framework 放置到 Framework 文件夹中

  4. Plugin 中 tencent_cloud_face_verify.podspec文件引入Framework tencent_cloud_face_verify.podspec

  1. Classes目录中创建OC和Swift 的桥接文件（因为人脸核身库使用OC 开发的，Swift 调用需要桥接文件指定.h头文件才能在Swift中正常调用OC 函数） TencentCloudFaceVerifyPlugin-Bridging-Header.h
