	CCUserDefault::sharedUserDefault()->setIntegerForKey("integer", 10);
	CCUserDefault::sharedUserDefault()->setFloatForKey("float", 2.3f);
	CCUserDefault::sharedUserDefault()->setDoubleForKey("double", 2.4);
	CCUserDefault::sharedUserDefault()->setBoolForKey("bool", true);

Get the above data output

	string str = CCUserDefault::sharedUserDefault()->getStringForKey("string");// Parameters ： Return key value according to the passed in key 
	CCLOG("str: %s", str.c_str());
	int i = CCUserDefault::sharedUserDefault()->getIntegerForKey("integer");
	CCLOG("i: %d", i);
	float f = CCUserDefault::sharedUserDefault()->getFloatForKey("float");
	CCLOG("f: %f", f);
	double d = CCUserDefault::sharedUserDefault()->getDoubleForKey("double");
	CCLOG("d: %f", d);
	bool b = CCUserDefault::sharedUserDefault()->getBoolForKey("bool");
	if (b)
		CCLOG("bool is true");
	else
		CCLOG("bool is false");

Change data

	CCUserDefault::sharedUserDefault()->setStringForKey("string", "test"); // changes string data 
	CCUserDefault::sharedUserDefault()->setFloatForKey("float", 3.1413);  // changes float data 

	string str1 = CCUserDefault::sharedUserDefault()->getStringForKey("string");
	CCLOG("str1: %s", str1.c_str());
	float f2 =CCUserDefault::sharedUserDefault()->getFloatForKey("float");
	CCLOG("f2: %f", f2);
