UIWeb​View 缓存

1.这是官方原版的，根据测试有网络直接读网络，没网络才会读本地

2.下面这个是根据我们的需求来修改了一下，我们的需求是有缓存的话，不用再次联网更新的，节约玩家的流量，
因为游戏基本是不会修改的，换了连接以后，缓存才会更新，这样就可以实现离线也可以很愉快的玩耍，下次再打开，就秒开啦

UIWeb​View 的一些注意点

1.当时我们还需要兼容iOS6版本的系统，在iOS6上面，比如分别有A和B两个控制器，
分别加载2个UIWeb​View,只有一个会正常运行，相同的测试在iOS7以上的版本不会有问题。

2.如果打着断点，给WebView调试的时候突然间奔溃了，把断点去掉即可，当初被这个给坑死了，谷歌后才知道

UIWeb​View利用CocoaHTTPServer开启本地服务器，加载本地资源

1.官方介绍

CocoaHTTPServer is a small, lightweight, embeddable HTTP server for Mac OS X or iOS applications.

Sometimes developers need an embedded HTTP server in their app.
Perhaps it's a server application with remote monitoring.
Or perhaps it's a desktop application using HTTP for the communication backend.
Or perhaps it's an iOS app providing over-the-air access to documents.
Whatever your reason, CocoaHTTPServer can get the job done. It provides:

Built in support for bonjour broadcasting
IPv4 and IPv6 support
Asynchronous networking using GCD and standard sockets
Password protection support
SSL/TLS encryption support
Extremely FAST and memory efficient
Extremely scalable (built entirely upon GCD)
Heavily commented code
Very easily extensible
WebDAV is supported too!

2.使用非常简单，照着官方的Demo试一下就行，建议使用cocopods安装

让UIWeb​View 有类似于微信的加载进度条

UIWeb​View Javascript进行交互

1.objective-c调用 javascript :

[webView stringByEvaluatingJavaScriptFromString:@"alert('done')"];

2.可以自定义协议，比如一个网页，你想调起原生的应用，可以自定义一个协议，通过UIWebView中的委托 shouldStartLoadWithRequest 方法。

NSString *requestString = [[request URL] absoluteString];
NSArray *components = [requestString componentsSeparatedByString:@"://"];
if ([components count] > 1 && [(NSString *)[components objectAtIndex:0] isEqualToString:@"这里一般写公司域名"]) {
    if ([[components lastObject] isEqualToString:@"share"]){
          DebugLog(@"监听到 webView 分享");
      }else if ([[components lastObject] isEqualToString:@"gameover"]) {
          DebugLog(@"监听到 webView 游戏结束");
    }
};

3.WebViewJavascriptBridge是一个Objective-C与JavaScript进行消息互通的三方库

试试这个库很不错,根据版本号切换iOS7 <-> iOS8
