篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了iOS第三方支付集成-支付宝支付相关的知识，希望对你有一定的参考价值。

吐槽一下支付宝的文档和demo，文档真是找的我眼花缭乱，demo写的也是看的捉急，没有微信的简单明了。不过全部找到后，静下心来研究，也还是可以的。

一进入官方下Demo,看文档

工欲善其事必先利其器，先看下demo总不是坏处，也可以学习一下支付宝大佬编码风格。除了不好找之外，其它还是可以的。
支付宝支付demo下载
 支付宝支付iOS集成文档
 支付宝支付通知参数说明

二正式接入准备工作

1.导入demo中以下文件

2.导入以下依赖库

3.Project-Info中，添加支付宝的AppKey

4.设置支付宝白名单

三正式接入

1.AppDelegate设置

2.接入PayManager支付工具类,也可以自己写一个。仅供参考
