支付功能在app中的实现

支付宝IOS2.2.1支付

将Demo中AlipaySDK.bundle AlipaySDK.framework libel.a lib crypto.a openssl Util加入到工程，在需要调用的地方加#import

            }

}

上面这段代码，payOrder 没有客户端的情况是从这里进的，支付流程中响应事件也是这个方法，但当客户端的时候，auth_V2WithInfo 会进入，响应事件的方法是下面processAuth_V2Result 方法，但是，当payOrder ，auth_V2WithInfo 在一起的时候，会很纠结，结果是wap或者客户端总有一个回调方法不响应，可能是自己搞不清文档的意思，可是你妹的写清楚点行不。然后，wap的时候进入的方法不变，客户端的时候响应方法加上processOrderWithPaymentResult ，你会发现，响应的方法和wap的方法是同一个，好像是把支付流程重新传入了payOrder里边。

notifyURL 是客户端传给支付宝的，当客户端支付完成后，支付宝会根据这个url异步调用服务端的接口，同步支付结果的数据，这个要服务器给的，确保你的私钥，合作者id是准确的。

建设银行支付
只支持html5格式的方式访问，当然html5页面的建行支付需要我们伟大的前端公司师实现了，我们只能通过向服务器发送请求加载html5页面。
