Apple Pay運行環境：iPhone6以上設備，操作系統最低iOS9.0以上，部分信息設置需要iOS9.2以上。目前還不支持企業證書添加。

環境搭建好後可以在模擬器上面運行，xcode7.2.1+iPhone6SP9.2系統下，系統會綁定幾種虛擬的銀行卡，和幾個聯系人，方便調試，支付也不會發生真實的付款，真的很方便。

准備工作

在接入Apple Pay之前，首先要申請MerchantID及對應證書。

 

申請MerchantID

申請對應證書

工程設置

Capability中啟用Apple Pay權限，並選擇merchantID。

之後項目會多一個Applepay的配置文件ApplePayDemo.entitlements

如果Steps出現那三項就證明配置正確
