ios原生态页面相对于HTML5页面具有渲染效果好，流畅，省流量的特点，但是比较难实现动态加载多个页面（如支付宝），动态修改页面布局。
我们使用的是WebViewJavascriptBridge这个第三方控件。
下面是一个完整的调用HTML5页面。
_bridge = [WebViewJavascriptBridge bridgeForWebView:self.webView webViewDelegate:self handler:^(id data, WVJBResponseCallback responseCallback) 这个是HTML5页面回调用的，没有这个一切免谈了，一切异常都处理不了，只能处理正常加载成功的情况。
