首选项存储:
bool HelloWorld::init()
{
//////////////////////////////
// 1. super init first
if ( !Layer::init() )
{
return false;
}
//存储数据
UserDefault::getInstance()->setStringForKey("data", "Hello World!");
//取出并打印数据 //根据key("data")获取数据,如果找不到则输出失败值"can not find!"
log("%s", UserDefault::getInstance()->getStringForKey("data", "can not find!").c_str());
return true;
}
读写文件:
写文件:
auto fu = FileUtils::getInstance();
FILE *f = fopen(fu->fullPathFromRelativeFile("data.txt", fu->getWritablePath()).c_str(), "w");
fprintf(f, "Hello World!\n");
fclose(f);
Data d = fu->getDataFromFile(fu->fullPathFromRelativeFile("data.txt", fu->getWritablePath()));
log("%s",d.getBytes());
读取plist文件
FileUtils *fu = FileUtils::getInstance();
ValueMap vm = fu->getValueMapFromFile("data.plist");
log("%s",vm["name"].asString().c_str());
读取xml文件
#include "tinyxml2.h"
auto doc = new tinyxml2::XMLDocument();
doc->Parse(FileUtils::getInstance()->getStringFromFile("data.xml").c_str());
auto root = doc->RootElement();
for (auto e = root->FirstChildElement(); e; e=e->NextSiblingElement()) {
std::string str;
for (auto attr = e->FirstAttribute(); attr; attr=attr->Next()) {
str+=attr->Name();
str+=":";
str+=attr->Value();
str+=",";
}
log("%s",str.c_str());
}
