IOS下的H5页面的支持

如题：这篇博客主要是为自己做笔记，实现的功能是ios的H5支持。

其中不仅实现了H5的支持，还包括了View的跳转操作，由于该H5是用于unity游戏内的，所以需要将H5和控制逻辑一起封装到一个view里面去，

对外置提供打开H5连接的接口。

先看下代码：

1.h文件，只需要定义并实现一个ViewController，并为其添加WebViewDelegate。

2.m文件，实现view和需要开放的接口

   [self initWebView];    //[self.view addSubview:mainWebView];}@end

注意：加了底色的代码是为unity专门封装的view跳转方法，如果感觉不太好的话，替换成下面的通用代码：

UIViewController * con = [UIApplication sharedApplication].keyWindow.rootViewController;
