iOS Apple Pay

iOS 苹果支付

需要证书支持支付功能

targets 打开支付功能按钮

//ApplePay
#import <PassKit/PassKit.h>                                 //用户绑定的银行卡信息
#import <PassKit/PKPaymentAuthorizationViewController.h>    //Apple Pay的展示控件
#import <AddressBook/AddressBook.h>                         //用户联系信息相关
PKPaymentAuthorizationViewControllerDelegate

注意:设置苹果支付不能自定义按钮,需要使用苹果提供的支付样式!
