动态更新，iOS有三种处理方案
1，开源框架reactive native，但是编程语言是js
iOS app可以在运行时从服务器拉去最新的js文件到本读，然后执行，因为js是一门动态的脚本语言
所以可以在运行时直接读取js文件执行，也因此能够实现iOS的热更新
2, lua脚本
Lua脚本如同js一样，也能在动态时被。之前愤怒的小鸟使用lua脚本做的一个插件wax,
可以实现使用lua写iOS应用。热更新时，从服务器拉去lua脚本然后
动态的执行就可以了。遗憾的是wax目前已经不更新了。
3， 使用oc语言的动态库framework。用oc进行热更新

步骤：
1，创建framework工程
iOS－－－－framework&library－－－－cocoa touch framework
2，代码处理
写一个controller的控制工具类
#import "HotUpdateControl.h" #import "AController.h" #import "BViewController.h" #import "CViewController.h" #import "DViewController.h" #import "EViewController.h" @implementation HotUpdateControl -(NSArray *)getVcs { return @[ [[AController alloc]init], [[BViewController alloc]init], [[CViewController alloc]init], [[DViewController alloc]init], [[EViewController alloc]init]]; } @end好了，开始打包framework，为了避免打包出来的framework，在真机上面运行不了，我们使用一个脚本来进行打包，目的是多型号CPU核心的合成，就是打出一个通用的包。
# Sets the target folders and the final framework product. # 如果工程名称和Framework的Target名称不一样的话，要自定义FMKNAME # 例如: FMK_NAME = "MyFramework" FMK_NAME=${PROJECT_NAME} # Install dir will be the final output to the framework. # The following line create it in the root folder of the current project. INSTALL_DIR=${SRCROOT}/Products/${FMK_NAME}.framework # Working dir will be deleted after the framework creation. WRK_DIR=build DEVICE_DIR=${WRK_DIR}/Release-iphoneos/${FMK_NAME}.framework SIMULATOR_DIR=${WRK_DIR}/Release-iphonesimulator/${FMK_NAME}.framework # -configuration ${CONFIGURATION} # Clean and Building both architectures. xcodebuild -configuration "Release" -target "${FMK_NAME}" -sdk iphoneos clean build xcodebuild -configuration "Release" -target "${FMK_NAME}" -sdk iphonesimulator clean build # Cleaning the oldest. if [ -d "${INSTALL_DIR}" ] then rm -rf "${INSTALL_DIR}" fi mkdir -p "${INSTALL_DIR}" cp -R "${DEVICE_DIR}/" "${INSTALL_DIR}/" # Uses the Lipo Tool to merge both binary files (i386 + armv6/armv7) into one Universal final product. lipo -create "${DEVICE_DIR}/${FMK_NAME}" "${SIMULATOR_DIR}/${FMK_NAME}" -output "${INSTALL_DIR}/${FMK_NAME}" rm -r "${WRK_DIR}" open "${INSTALL_DIR}"
点击1，添加一个脚本2-－－－HotUpdateScript,然后点击3，产生4的Run Script,然后把脚本复制进去，再点击5，选择脚本打包编译
复制到另一个项目的沙箱里面去，就可以给另外的项目使用
33，建立一个主项目，就是使用这些动态库的工程
现在进行读取离线包的测试，只要这个项目，能够从沙箱里面读取到代码文件，就意味着可以在线更新代码，远程升级，
我修改了UITabBarConroller加载板块的初始化方法，如果沙箱有framework动态库，就加载framework动态库上面的版块，令到项目可以模块化

如果 是本地的默认版本，应该是
@[@"首页"，@“广场”，@“朋友圈”，@“我的”，@“设置”]的模块
但如果是沙箱里面的模块，那么就应该是ABCDE

Lua热更新
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝
Cocos2d-x已经封装了用于实现热更新功能的类，就是assetsmanager
api说明：
// 检测是否有版本更新 virtual bool checkUpdate();
// 下载更新的资源包并解压到下载路径 virtual void update();
// 获取当前客户端版本号 std::string getVersion();
// 删除客户端版本号 void deleteVersion();
// 设置下载回调（AssetsManagerDelegateProtocol） void setDelegate(AssetsManagerDelegateProtocol *delegate);
// 设置连接超时时间（单位：秒） void setConnectionTimeout(unsigned int timeout); // 设置从服务端下载资源包的url void setPackageUrl(const char* packageUrl);
// 设置服务端获取版本号的url void setVersionFileUrl(const char* versionFileUrl);
// 设置资源保存路径 void setStoragePath(const char* storagePath);
因为AssetsManager使用了pthread库，所以需要在win32工程中需要包含pthread库所在目录。
VS在工程属性——C/C++——常规——附加包含目录中添加：$(ProjectDir)..\..\..\cocos2dx\platform\third_party\win32\pthread
