一：支付宝支付

1：签约成为支付宝商户获取“私钥(PID)”和“秘钥”

签约时一定要有公司营业执照签约步骤

2：App支付客户端DEMO&SDK

3：集成支付宝SDK步骤iOS集成流程

4:支付宝支付回调

注意: 一定不能以客户端返回作为用户支付的结果，应以服务器端的接收的支付通知或查询API返回的结果为准。

二：微信支付

1：微信商户申请步骤

商户在微信公众平台或开放平台提交微信支付申请，微信支付工作人员审核资料无误后开通相应的微信支付权限。微信支付申请审核通过后，商户在申请资料填写的邮箱中收取到由微信支付小助手发送的邮件，此邮件包含开发时需要使用的支付账户信息

2：资源下载微信SDK及demo下载

3：iOS接入指南

指南APP端开发步骤
 IOS开发要点说明

4：支付结果回调

照微信SDK Sample，在类实现onResp函数，支付完成后，微信APP会返回到商户APP并回调onResp函数，开发者需要在该函数中接收通知，判断返回错误码，如果支付成功则去后台查询支付结果再展示用户实际支付结果。

注意: 一定不能以客户端返回作为用户支付的结果，应以服务器端的接收的支付通知或查询API返回的结果为准。

// 支付返回结果，实际支付结果需要去微信服务器端查询
-(void)onResp:(BaseResp *)resp {
   if([resp isKindOfClass:[PayResp class]]){
      switch (resp.errCode) {
          case WXSuccess:{
             NSlog(@"支付成功");
            // 发通知带出支付成功结果
                [[NSNotificationCenter defaultCenter] postNotificationName:ZLWXReturnSucceedPayNotification object:resp];
          }
            break;
        default:{
            NSlog(@“支付失败:%d”,resp.errCode);
             // 发通知带出支付失败结果
                [[NSNotificationCenter defaultCenter] postNotificationName:ZLWXReturnFailedPayNotification object:resp];
        }
          break;
    }
  }  
}
