现在的支付方式一般有三种, 支付宝, 微信, 网银. 个人觉得最简单易用的还是支付宝, 微信虽然看起来币支付宝要简单,但是后端太麻烦了, 网银就不说了.
先放出官方文档,免得还有人找不到文档: https://doc.open.alipay.com/doc2/detail?treeId=59&articleId=103563&docType=1

环境搭建

• 下载AliPayDK,官方链接,更新时间:2016/01/28 : http://aopsdkdownload.cn-hangzhou.alipay-pub.aliyun-inc.com/demo/WS_MOBILE_PAY_SDK_BASE.zip?spm=0.0.0.0.y0oP1q&file=WS_MOBILE_PAY_SDK_BASE.zip
  如果下载失败,请换个浏览器(至少我用QQ浏览器没有下载成功)

• 所需文件导入
  1.按以下路径
  ~/支付宝钱包支付接口开发包2.0标准版(20160120)/DEMO/客户端demo/支付宝钱包支付接口开发包2.0标准版(iOS 15.0.6)
  找到库文件AlipaySDK.framework和资源包AlipaySDK.bundle拖入到你的工程中,
  2.AliSDKDemo中libcrypto.a和libssl.a导入到你的工程
  3.~/AliSDKDemo/AliSDKDemo下的openssl文件夹,Util文件夹,Order.h,Order.m拖入工程
  4.导入以下库
  如果是Xcode 7.0之后的版本，需要添加libc++.tbd、libz.tbd；
  如果是Xcode 7.0之前的版本，需要添加libc++.dylib、libz.dylib
  

  

• 工程设置修改

  1.info.plist配置
  如果是iOS9.0之后(Xcode7.0)在info.plist中增加以下字典
  (也可以单独配置,有需要的请看官方文档)
  

设置Schemes
在info下 URL Types设置你的Schemes

2.Build Settings配置
以关键字“search”搜索，对“Header Search Paths”增加头文件路径：$(SRCROOT)/项目名称

3.这时候编译会报错,错误信息是
Cannot find interface declaration for 'NSObject', superclass of 'Base64'
那么需要打开报错了的文件，增加头文件。
import <Foundation/Foundation.h>
再编译,就ok了

支付信息配置

在需要支付的文件中导入头文件

<code class="language-Objective-C hljs vala has-numbering"><span class="hljs-preprocessor">#import <AlipaySDK/AlipaySDK.h></span>
<span class="hljs-preprocessor">#import "DataSigner.h"</span>
<span class="hljs-preprocessor">#import "Order.h"</span></code>

配置订单信息
这些都是示例信息,这些事不能完成支付的,要以实际信息为准才能完成支付

<code class="language-Objective-C hljs objectivec has-numbering"><span class="hljs-comment">//商户ID</span>
    <span class="hljs-built_in">NSString</span> *partner = @<span class="hljs-string">""</span>;

                       orderSpec, signedString, @<span class="hljs-string">"RSA"</span>];

        [[AlipaySDK defaultService] payOrder:orderString fromScheme:appScheme callback:^(<span class="hljs-built_in">NSDictionary</span> *resultDic) {
            <span class="hljs-comment">//【callback处理支付结果】</span>
            <span class="hljs-built_in">NSLog</span>(@<span class="hljs-string">"reslut = %@"</span>,resultDic);
        }];
    }</code>

就这么多,如果手机装有支付宝客户端, 则直接调用客户端,如果没有客户端则调用网页版
