"iOS8.1就已经有这个功能了，只是木有现在这么的火，现在的趋势是要火的节奏，因此很多电商平台B2B,P2P,C2C,X2X都有可能需要这个屌丝的付款功能了，在此简单的研究一下。"
第一步先修改target为iOS 8.1，当然支持中国的需要9.2以上且需要iPhone6以上了，然后在项目Capabilities里将Apple Pay设置为on，这将自动导入需要的库文件，然后添加一个权限文件并设置，最后修改或创建你的App ID。
正如上图提示的一样，你可能会注意到上面没有有效的Merchant ID，我们需要创建一个，访问苹果iOS 开发者中心的位于Identifiers > Merchant ID的页面。然后随着流程指引，创建一个Merchant ID并注册它。这个和其他证书差不多再此不做过多的阐述。下图是已经创建好的参考图片。
下载安装然后刷新下刚刚项目里面的界面，选择打勾即可，可以看到如下图
下面简单说下代码：

在此过程中你可能会遇到如下问题：
1.countryCode 不知道怎么查，我这写的是中国的countryCode查询网站
2.currencyCode 不会查，到目前为止，我也没搞懂，在错误信息里面提示一堆，随便选的一个。
3.木有iPhone6手机，我就是其中之一…….
其他我认为比较重要的属性，请详细看Demo具体效果图如下：
