ios的app，有新版本时必须先更新。

现在没时间整理，先把代码贴出来，以后再做详细的思路整理。

1 在AppController.mm的didFinishLaunchingWithOptions方法里面获取本地应用版本信息，保存起来。

 // about App version

    NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary];  

    NSString *versionStr = [infoDictionary objectForKey:@"CFBundleShortVersionString"];

    SettingsManager::getInstancePtr()->getShortVersion() = [ versionStr UTF8String ];

2 在加载页面，使用http向服务器版本信息，如果返回的版本信息和在第一步中得到的不一致，进入混编文件。

　　这只是一些参数。

 //转到appstore 里面

        std::string t = MessageManage::getInstancePtr()->getStrMessage(String_Alter_Version_Title);

        std::string c = MessageManage::getInstancePtr()->getStrMessage(String_Alter_Version_Content);

        std::string b = MessageManage::getInstancePtr()->getStrMessage(String_Alter_Version_Btn);

        ICheckVersionHelper::getInstancePtr()->alertView(t,c,b);

3 我把具体的类都贴上来，包括
