因为常用cocos2dx开发游戏，所以每次新建cpp类文件的时候，XCode默认生成的cpp类基本就是一个空文件，每次都要重复实现cocos2dx的基本代码。很麻烦。（虽然我每次都是修改了HelloWorld文件，新建的文件直接copy HelloWorld内容。感觉还是挺麻烦的。）

今天就修改了下类模板，添加了2个cocos2dx的类模板，下面是新建文件的时候，是不是多出了2个类模板。

下面我就说下怎么添加xcode类模板，很简单的。

1、打开Xcode的类模板目录地址：/Applications/Xcode.app/Contents/Developer/Library/Xcode/Templates/File Templates

2、打开里面C and C++文件，就会看到Xcode的cpp类模板文件。复制一个C++ Class.xctemplate文件夹取名：2dx Scene Class.xctemplate，放在C and C++目录下。

3、修改TemplateInfo.plist（主要修改创建文件时候的描述介绍）

打开2dx Scene Class.xctemplate/TemplateInfo.plist, 修改Description的值为：A C++ class for Cocos2d-x Scene.

4、修改___FILEBASENAME___.h

打开2dx Scene Class.xctemplate/___FILEBASENAME___.h，修改成以下内容：

[cpp]//// ___FILENAME___// ___PROJECTNAME___//// Created by ___FULLUSERNAME___ on ___DATE___.//___COPYRIGHT___//#ifndef _____PROJECTNAMEASIDENTIFIER________FILEBASENAMEASIDENTIFIER_____#define _____PROJECTNAMEASIDENTIFIER________FILEBASENAMEASIDENTIFIER_____#include "cocos2d.h"USING_NS_CC;class ___FILEBASENAMEASIDENTIFIER___ : public Layer{public:___FILEBASENAMEASIDENTIFIER___();~___FILEBASENAMEASIDENTIFIER___();static Scene* createScene();virtual bool init();CREATE_FUNC(___FILEBASENAMEASIDENTIFIER___);private:void initData();};#endif /* defined(_____PROJECTNAMEASIDENTIFIER________FILEBASENAMEASIDENTIFIER_____) */[/cpp]5、修改___FILEBASENAME___.cpp打开2dx Scene Class.xctemplate/___FILEBASENAME___.cpp，修改成以下内容：[cpp]//// ___FILENAME___// ___PROJECTNAME___//// Created by ___FULLUSERNAME___ on ___DATE___.//___COPYRIGHT___//#include "___FILEBASENAME___.h"___FILEBASENAMEASIDENTIFIER___::___FILEBASENAMEASIDENTIFIER___(){}___FILEBASENAMEASIDENTIFIER___::~___FILEBASENAMEASIDENTIFIER___(){}Scene* ___FILEBASENAMEASIDENTIFIER___::createScene(){auto scene = Scene::create();auto layer = ___FILEBASENAMEASIDENTIFIER___::create();scene->addChild(layer);return scene;}bool ___FILEBASENAMEASIDENTIFIER___::init(){if ( !Layer::init() ){return false;}initData();return true;}#pragma mark – initDatavoid ___FILEBASENAMEASIDENTIFIER___::initData(){Size visibleSize = Director::getInstance()->getVisibleSize();// add your codes here…}[/cpp]ok, 这样就完成了一个类模板的添加。现在在XCode里面新建一个2dx Scene类看看。是不是已经有默认内容了。[cpp]//// MyScene.h// MagicDemo//// Created by LiuYanghui on 13-12-27.////#ifndef __MagicDemo__MyScene__#define __MagicDemo__MyScene__#include "cocos2d.h"USING_NS_CC;class MyScene : public Layer{public:MyScene();~MyScene();static Scene* createScene();virtual bool init();CREATE_FUNC(MyScene);private:void initData();};#endif /* defined(__MagicDemo__MyScene__) */[/cpp][cpp]//// MyScene.cpp// MagicDemo//// Created by LiuYanghui on 13-12-27.////#include "MyScene.h"MyScene::MyScene(){}MyScene::~MyScene(){}Scene* MyScene::createScene(){auto scene = Scene::create();auto layer = MyScene::create();scene->addChild(layer);return scene;}bool MyScene::init(){if ( !Layer::init() ){return false;}initData();return true;}#pragma mark – initDatavoid MyScene::initData(){Size visibleSize = Director::getInstance()->getVisibleSize();// add your codes here…}[/cpp]对应的你可以添加Layer的类模板。方法一样，我就不重复了。关于文件模板里面的一个预定义变量，介绍下：macro_fileok，还有很多有趣的功能，可以大家自己探索。比如工程模板，插件等等。
