UIWebView各种加载网页的方式

UIWebView加载网页的方法

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">
