UIWebView
detailWeb = UIWebView.init(frame: CGRect.init(x: 0, y: 0, width: Href.screenWidth(), height: 1))
detailWeb?.loadHTMLString(html, baseURL: URL.init(string: kBaseUrl))
detailWeb?.delegate=self
func webViewDidFinishLoad(_ webView: UIWebView) {
//获取到webview的高度
let webHeight = (self.detailWeb?.stringByEvaluatingJavaScript(from: "document.body.offsetHeight"))! as NSString
//重置坐标
}
WKWebView
//解决加载完一片空白的问题
