1. 判断操作系统平台类型
根据Cocos2d-x源码可以获得所支持的平台类型
C++ cocos2d\platform\CCPlatformConfig.h

Lua
Cocos2dx中预定义了所支持的操作系统平台
-- 目标平台操作系统
cc.PLATFORM_OS_WINDOWS = 0
cc.PLATFORM_OS_LINUX = 1
cc.PLATFORM_OS_MAC = 2
cc.PLATFORM_OS_ANDROID = 3
cc.PLATFORM_OS_IPHONE = 4
cc.PLATFORM_OS_IPAD = 5
cc.PLATFORM_OS_BLACKBERRY = 6
cc.PLATFORM_OS_NACL = 7
cc.PLATFORM_OS_EMSCRIPTEN = 8
cc.PLATFORM_OS_TIZEN = 9
cc.PLATFORM_WINRT = 10
cc.PLATFORM_OS_WP8 = 11
可使用getTargetPlatform获取目前操作系统平台的类型，其返回值为常量数值。
local targetPlatform = cc.Application:getInstance():getTargetPlatform()
为便于开发测试，并在做定义并区分，具体根据实际情况而定。
-- 平台类型定义
cc.PLATFORM_OS_APPLE_REAL = 12 -- 苹果真机：ipad或iphone
cc.PLATFORM_OS_DEVELOPER = 13 -- 开发者模式：windows或mac
cc.exports.TARGET_PLATFORM = application:getTargetPlatform()
if TARGET_PLATFORM==cc.PLATFORM_OS_IPHONE or TARGET_PLATFORM==cc.PLATFORM_OS_IPAD then
TARGET_PLATFORM = cc.PLATFORM_OS_APPLE_REAL
elseif TARGET_PLATFORM==cc.PLATFORM_OS_WINDOWS or TARGET_PLATFORM==cc.PLATFORM_OS_MAC then
TARGET_PLATFORM = cc.PLATFORM_OS_DEVELOPER
end
