此d出框功能：自定义添加按钮 Title 内容 模态实现

直接上代码：

使用方法:

PopupLayer* pl = PopupLayer::create("popuplayer/BackGround.png");	// ContentSize 是可选的设置，可以不设置，如果设置把它当作 9 图缩放	pl->setContentSize(CCSizeMake(400,350));	pl->setTitle("test");	pl->setContentText(G2U("你好,d出框"),20,60,250);	// 设置回调函数，回调传回一个 CCNode 以获取 tag 判断点击的按钮	// 这只是作为一种封装实现，如果使用 delegate 那就能够更灵活的控制参数了	pl->setCallbackFunc(this,callfuncN_selector(LoginScene::buttonCallback));	// 添加按钮，设置图片，文字，tag 信息	pl->addbutton("popuplayer/pop_button.png","popuplayer/pop_button.png",G2U("确定"),0);	pl->addbutton("popuplayer/pop_button.png",G2U("取消"),1);	// 添加到当前层	this->addChild(pl);

G2U是 gbk转UTF_8 要不然的话 中文会乱码

函数如下：

char* G2U(const char* gb2312){	int len = MultiBytetoWIDeChar(CP_ACP,gb2312,-1,NulL,0);	wchar_t* wstr = new wchar_t[len+1];	memset(wstr,len+1);	MultiBytetoWIDeChar(CP_ACP,wstr,len);	len = WIDeCharToMultiByte(CP_UTF8,NulL);	char* str = new char[len+1];	memset(str,len+1);	WIDeCharToMultiByte(CP_UTF8,str,len,NulL);	if(wstr) delete[] wstr;	return str;}
