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

but.setTitle("
支付", forState: UIControlState.Normal);

but.addTarget(self, action: "click", forControlEvents: UIControlEvents.TouchUpInside);
self.view.addSubview(but);    }
func click()
{
AliplayFunc();
print("click")
}
