新手CrossApp 之demo SecondViewController小结

void SecondViewController::viewDidLoad(){  

    loadJsonData();  

    //上下刷新视图的创建  

    CAPullToRefreshView* headerRefreshView = CAPullToRefreshView::create(CAPullToRefreshView::CAPullToRefreshTypeHeader);  

    CAPullToRefreshView* footerRefreshView = CAPullToRefreshView::create(CAPullToRefreshView::CAPullToRefreshTypeFooter);  

    //创建了一个tableView，tableView每一行只有一个cell  

    p_TableView = CATableView::createWithFrame(this->getView()->getBounds());  

    p_TableView->setTableViewDataSource(this);  //设置数据代理  

    p_TableView->setTableViewDelegate(this);    //设置事件处理  

    p_TableView->setTableHeaderView(headerRefreshView); //设置头部刷新视图  

    p_TableView->setTableFooterView(footerRefreshView); //设置尾部刷新视图  

    p_TableView->setAllowsSelection(true);              //设置是否可选  

    p_TableView->setScrollViewDelegate(this);           //设置scroll代理  

    this->getView()->addSubview(p_TableView);           //添加进主视图  

}  tableCellAtIndex这个方法是在tableview中创建创建

CATableViewCell* SecondViewController::tableCellAtIndex(CATableView* table, const CCSize& cellSize, unsigned int section, unsigned int row){  

    CCSize _size = cellSize;  

    Info* p_List = (Info*)personList.at(row);//CADeque personList中寻找第几号元素  

    CATableViewCell* cell = table->dequeueReusableCellWithIdentifier("CrossApp");//寻找有没有"CrossApp"的cell,肯定是没有的所以每次都会进入if  

    if (cell==NULL)  

    {  

        //_size.width*0.2, _size.height*0.5, _size.width*0.2, _size.height  

        cell = CATableViewCell::create("CrossApp");//创建  

        CALabel* p_name=CALabel::createWithCenter(CCRect(_size.width*0.2, _size.height*0.5, _size.width*0.2, _size.height));//创建一个lable  

        p_name->setTag(9);                        //设置标记  

        p_name->setFontSize(_px(30));  

        p_name->setColor(CAColor_blue);  

        p_name->setTextAlignment(CATextAlignmentCenter);  

        p_name->setVerticalTextAlignmet(CAVerticalTextAlignmentCenter);  

        cell->addSubview(p_name);                 //添加进去     

  

        CALabel* p_num = CALabel::createWithCenter(CCRect(_size.width*0.4, _size.height*0.5, _size.width*0.2, _size.height));  

        p_num->setTag(10);  

        p_num->setFontSize(_px(30));  

        p_num->setColor(CAColor_blue);  

        p_num->setTextAlignment(CATextAlignmentCenter);  

        p_num->setVerticalTextAlignmet(CAVerticalTextAlignmentCenter);  

        cell->addSubview(p_num);  

  

        CALabel* p_gender = CALabel::createWithCenter(CCRect(_size.width*0.6, _size.height*0.5, _size.width*0.2, _size.height));  

        p_gender->setTag(11);  

        p_gender->setFontSize(_px(30));  

        p_gender->setColor(CAColor_blue);  

        p_gender->setTextAlignment(CATextAlignmentCenter);  

        p_gender->setVerticalTextAlignmet(CAVerticalTextAlignmentCenter);  

        cell->addSubview(p_gender);  

  

        CALabel* p_occupation = CALabel::createWithCenter(CCRect(_size.width*0.8, _size.height*0.5, _size.width*0.2, _size.height));  

        p_occupation->setTag(12);  

        p_occupation->setFontSize(_px(30));  

        p_occupation->setColor(CAColor_blue);  

        p_occupation->setTextAlignment(CATextAlignmentCenter);  

        p_occupation->setVerticalTextAlignmet(CAVerticalTextAlignmentCenter);  

        cell->addSubview(p_occupation);  

    }  

    CALabel* p_name = (CALabel*)cell->getSubviewByTag(9);    //获取label 标记  

    p_name->setText(p_List->name.c_str());                   //设置label的数据类容，这样的数据类容肯定为空   

    CALabel* p_num = (CALabel*)cell->getSubviewByTag(10);  

    p_num->setText(p_List->num.c_str());  

    CALabel* p_gender = (CALabel*)cell->getSubviewByTag(11);  

    p_gender->setText(p_List->gender.c_str());  

    CALabel* p_occupation = (CALabel*)cell->getSubviewByTag(12);  

    p_occupation->setText(p_List->occupation.c_str());  

    return cell;  

  

}  接下来personList 这个CADeque数据从哪里来的







void SecondViewController::loadJsonData(void){  

      

    Reader reader;  

    Value value;  

    //首先要找到一个名字叫做information.json文件，这个文件在source目录下  

    string jsonFile = CCFileUtils::sharedFileUtils()->fullPathForFilename("information.json");  

    //把文件里的类容变成CCString 格式  

    CCString* jsonData = CCString::createWithContentsOfFile(jsonFile.c_str());  

    //解析这种格式，放入value中  

    if (reader.parse(jsonData->getCString(),value))  

    {  

        //有一个Info.h类，里面有4个  

        //std::string name;  

        //std::string num;  

        //std::string gender;  

        //std::string occupation;  

  

  

        int length = value.size();  

        for (int index = 0; index < length;index++)  

        {  

            Info* personInfo = new Info();  

            personInfo->autorelease();  

            personInfo->name = value.**tring();  

            personInfo->num = value.**tring();  

            personInfo->gender = value.**tring();  

            personInfo->occupation = value.**tring();  

            personList.pushBack(personInfo);  //放入personList  

        }  

    }  

}
