首先sdk
银联开放平台： https://open.unionpay.com/ajweb/product/detail?id=3
添加依赖库 3 个
libz
CFNetwork
SystemConfiguration
拖入需要文件
UPPaymentControl.h
libPayMentControl.a
RSA.h
RSA.m
修改配置
1 URL Types - URL Schemes
2 info plist 添加
LSApplicationQueriesSchemes <NSArray>
value - uppaysdk uppaywallet uppayx1 uppayx2 uppayx3
3 other link 添加路径
-force_load $(PROJECT_DIR)/upppay/libPaymentControl.a
4 将使用UPPay 的 VC，修改为 .mm
基本上就 差不多
Appdelegate 复制代码
