iOS 集成银联支付
今天闲着没事做，集成了一下银联支付，原来的项目中都是支付宝、微信支付。其实步骤很简单，只要配置正确了，还是挺好做的。
首先是sdk下载地址：https://open.unionpay.com/ajweb/help/file/toDetailPage?id=346&flag=2
以下是测试用卡号、手机号等信息（此类信息仅供测试使用，不会发生真实交易）
| 招商银行借记卡：6226090000000048 |
| 华夏银行贷记卡：6226388000000095 |
一，工程配置
1、 使用UPPaymentControl需要添加CFNetwork.framework、ＳystemConfiguration.framework、libz、libPaymentControl.a到工程中，添加后如下图：
2、在工程info.plist设置中添加一个URL Types回调协议(在UPPayDemo工程中使用“UPPayDemo”作为协议)，用于在支付完成后返回商户客户端。
3、http请求设置
在Xcode7.0之后的版本中进行http请求时，需要在工程对应的plist文件中添加NSAppTransportSecurity Dictionary并同时设置里面NSAllowsArbitraryLoads 属性值为 YES，具体设置可参照以下截图：
4、添加协议白名单
在Xcode7.0之后的版本中进行开发，需要在工程对应的plist文件中，添加LSApplicationQueriesSchemes Array并加入uppaysdk、uppaywallet、uppayx1、uppayx2、uppayx3五个item，具体设置可参考以下截图：
或者直接添加如下代码到plist文件中：
| <key>LSApplicationQueriesSchemes</key> <array> <string>uppaysdk</string> <string>uppaywallet</string> <string>uppayx1</string> <string>uppayx2</string> <string>uppayx3</string> </array> |
6.工程的 Build Settings 中找到 Other Linker Flags 中添加-ObjC 宏;
二，注意
银联支付目测只需要2个参数 1 tn 其实就是订单号 2 mode 是测试环境还是线上环境
和支付宝不同的是 支付宝要求本地把订单的信息书写完毕 调起sdk支付即可 银联是我把一些生成订单的信息 如 付款方 收款方 订单描述 金额等信息传递到服务器 由服务器生成一个订单号 然后客户端调起sdk进入支付
mode 是个字符串 "00" 表示线上环境"01"表示测试环境
返回的代理结果 :success、fail、cancel,分别代表:支付成功、支付失败、用户取消支付
三，集成到工程中
