比较简单，只做一个笔记，并于以后查询
1、将微信支付第三方库拖到项目中
项目中微信第三方支付截图
2、添加微信支付需要的依赖库
微信支付需要的依赖库.png
3、环境配置
1）、https相关配置
https-info.plist中配置.png
2）、LSApplicationQueriesSchemes白名单设置
添加微信白名单.png
3）、URL Schemes配置，这边涂鸦掉的数值，和项目中注册微信支付时的appID一致
截图
有两种方法设置，一种是在plist文件中
URL Schemes
第二种是图形样式，info->URL Types
URL Types截图
4）、bitcode配置
build setting -> bitcode
项目截图
3、项目代码
控制器中的代码
代码中相关appID等参数写在头文件中，不方便写出来，换成自己项目中的配置参数就可以了
