获取IOS设备的系统版本，硬件名称，mac地址

获取IOS设备的系统版本，硬件名称，mac地址

今天介绍的是如何获取ios设备的系统版本，硬件设备名称，和mac地址，我们做的游戏打算用mac地址来作为快速登录的账号，所以需要获取设备的mac地址，苹果设备的uuid现在苹果不让用了，所以用mac地址是一个比较好的选择，这里我们获取系统版本和设备名称则是为了统计使用，这里就不多做介绍了。

我现在做的项目是cocos2d-x的项目，所以这里就涉及到在C++代码里边调用OC代码，那么就会有一个新语言的名字，叫做Objective-C++，这其实就是OC和C++的混合写法，这种代码，我们需要把.cpp或者.m改成.mm文件，这种文件里，就可以实现C++与OC的混编了。好了，我这就把代码贴出来，大家一看就知道是怎么回事了，实现起来很简单的。

}

好了，代码就是这样了，这几个函数都是静态函数，调用起来很简单

CCLog("%s",GetMacAddress::getMacAddress());
GetMacAddress::getSystem();
GetMacAddress::getDeviceType();

这个功能就是这么实现了，日后做安卓版本的时候，会再把安卓的相应代码贴出来，如有问题，请给我留言
