swift调用支付宝

开发环境xcode7.1 运行环境 IOS9.1

到支付宝面面下载IOS的移动支付功能的SDK（Android和IOS是同一个zip文件下）

http://doc.open.alipay.com/doc2/detail?treeId=54&articleId=103419&docType=1

然后申请商家支付宝，得到相应的private_key和partner,seller

IOS的资料在SDK文件夹的“客户端demo”下的IOS文件夹下

• 复制AlipaySDK.bundle和AlipaySDK.framework到项目下

• 复制IOS Demo下的两个.a文件到项目下

• 复制iOS Demo下的openssl文件夹，Util文件夹，Order.h，Order.m（省得自己在swift中定义订单）文件到项目中

• 在xcode中创建一个项目AlipayDemo，在项目中Add Files to AlipayDemo所有的.a文件和openssl文件夹，Util文件夹，Order.h，Order.m，此时系统提示创建头文件，选择允许创建(可以手动添加一个.h文件作为头文件)

  

• 如果在基于IOS9.0编译，在info.list中添加如下xml代码（info.list以SourceCode形式打开）

<key>NSAppTransportSecurity</key>
   <dict>
       <key>NSExceptionDomains</key>
       <dict>
           <key>alipay.com</key>
           <dict>
                <!--Include to allowsubdomains-->
               <key>NSIncludesSubdomains</key>
                <true/>
                <!--Include to allowinsecure HTTP requests-->
               <key>NSTemporaryExceptionAllowsInsecureHTTPLoads</key>
                <true/>
                <!--Include to specifyminimum TLS version-->
               <key>NSTemporaryExceptionMinimumTLSVersion</key>
               <string>TLSv1.0</string> 
               <key>NSTemporaryExceptionRequiresForwardSecrecy</key>
                <false/>
           </dict>
       </dict>
</dict>

• 增加头文件

Util中的base64.h，openssl_wrapper.h添加#import <Foundation/Foundation.h>，给支付宝AlipaySDK.h添加#import <Foundation/Foundation.h>和#import<UIKit/UIKit.h>

• 设置Build Settings

查找Bitcode，把Yes改成No

查打Header SearchPaths，点小+号，添加$(SRCROOT)/AlipayDemo

 

• 在info的URL Types中添加一个GSWAlipayDemo的节点，以备代码中Order的appScheme使用。

• 代码实现
