学生信息管理系统（cocos2d引擎）——数据结构课程设计

老师手把手教了两天半，看了一下模式，加了几个功能就大功告成了！！！

给我的感想就是全都是指针！

添加图片精灵：

CCSprite* spBG = CCSprite::create("");

this->addChild(spBG);　　//添加到当前层

spGB->setPosition(ccp(x,y));　　//设置坐标

spGB->setScale(0.5);　　//缩放

文字按钮：

CCMenuItemFont* pItem = CCMenuItemFont::create("wenzi",this,menu_selector(回调函数));

再将文字按钮添加到菜单中

CCMenu* menu = CCMen::create(pItem,NULL);

this->addChild(menu);

menu->setPosition(ccp(x,y));

//创建文本

CCLabelTTF* ttf = CCLabelTTF::create("wenben","字体",48.0f);

this->addChild(ttf);

ttf->setPosition(cco(x,y));

//创建输入框(1、九点图，2、输入框)

CCScale9Sprite* input = CCScale9Sprite::create("");

accountBox = CCEditBox::create(CCSizeMake(r,c),input);

this->addChild(accounBox);

accountBox->setPosition(ccp(x,y));

accountBox->setInputFlag(kEditBoxInputFlagPassword);　　//输入模式为密码输入

按钮回调函数，看输入框accountBox的内容是否是密码；

不是密码：

弹出输入框　　CCMessageBox("","");

是密码切换场景

CCDirector* director = CCDirector::sharedDirector();

director->replaceScene(ListViewLayer::scene());　　//另一个头文件，里面的一个场景；

接下来，和之前的一样了；无非就是一些按钮，文本，输入框。

在init()里面画好面板；

各种按钮里面的回调函数。

然后中文转码utf-8老师已经写好了；

贴上自己写的东西，其他的老师已经写好了
