最近在使用UIWebView的时候遇到各种不同形式加载网页的方式，总结起来共有三种方式，分别为：使用URL加载，使用HTML源码加载，使用HTML文件加载，各种方法的使用如下：
直接使用URL加载
NSURL *url = [NSURL URLWithString: @"http://ss.zhiless.com/hjyAuth.do?token=61cbdd8c97273f9aa7d878b04e2c94c1"];
NSURLRequest *request = [NSURLRequest requestWithURL: url];
[self.webView loadRequest:request];
加载HTML源码
[self.testWebView loadHTMLString:@"
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0, user-scalable=yes">
