1. 准备工作
//微信支付商户号 #define MCH_ID @"YOUR_MCH_ID" //开户邮件中的(公众账号APPID或者应用APPID) #define WX_AppID @"YOUR_WX_AppID" //安全校验码(MD5)密钥,商户平台登录账户和密码登录http://pay.weixin.qq.com 平台设置的“API密钥”,为了安全,请设置为以数字和字母组成的32字符串。 #define WX_PartnerKey @"YOUR_WX_PartnerKey" //获取用户openid,可使用APPID对应的公众平台登录http://mp.weixin.qq.com 的开发者中心获取AppSecret。 #define WX_AppSecret @"YOUR_WX_AppSecret" 2. 集成开发流程
info里面配置添加白名单
配置URL Schemes,用来进行程序之间的跳转
