第一种：以文件的形式加载HTML资源

优点：最简单
缺点：有些HTML中的样式不支持file:在样式和功能上有缺失
作法：
  1.将所有的H5文件(含html、css、js、images）都放入一个文件夹中(例如：HtmlFile)
  2.将这个文件夹以相对路径的方式导入到工程代码中（例如放到Resource文件夹下）
  3.获取本地的文件路径：（例如打开首页：index.html）

选相对路径.png

放入工程后.png

/**参数1：index 是要打开的html的名称
    参数2：html 是index的后缀名
    参数3：HtmlFile/app/index 是文件夹的路径
*/
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html" inDirectory:@"HtmlFile/app/index"];
 NSURL *pathURL = [NSURL fileURLWithPath:filePath];
  [_webView loadRequest:[NSURLRequest requestWithURL:pathURL]];

第二种：搭建本地服务器，通过本地服务器加载本地HTML文件

     优点：同网络服务器加载的样式和功能完全一致
      缺点：需要额外搭建本地服务器、HTML文件的路径需要处理
      做法：
          1.用CocoaHTTPServer搭建本地服务器 pod 'CocoaHTTPServer'
          2.引入HTML文件，需要注意index.html要与css样式和其他功能包在一个路径下
         3.需要处理本地服务器的启动和关闭

AppDelegate中：

      /**本地服务器端口*/
@property (nonatomic,copy) NSString *serverPort;

#import <HTTPServer.h>//本地服务器
#import "BYHomeWebVC.h"//首页WebVC
/**本地服务器*/
