  10 <p>今天试着把代码升级至3.0，发现之前的CCArray的容器都变了，现在是使用Vector<T>与Map<K,V>，简单用法</p>
  11 <pre>
  12 cocos2d::Vector<Sprite> sprites;
  13
  14 auto sprite1 = Sprite::create("hello.png");
  15 auto sprite2 = Sprite::create("hello.png");
  16 auto sprite3 = Sprite::create("hello.png");
  17 auto sprite4 = Sprite::create("hello.png");
  18
  19 sprites.push_back(sprite1)
  20 sprites.push_back(sprite2)
  21 sprites.push_back(sprite3)
  22 sprites.push_back(sprite4)
  23 </pre>
  24 <p>@sprites@ 内存管理是由编译器自动处理的，不要使用new来申请堆空间。</p>
  25 <pre>
  26 cocos2d::Map<std::string, Node> nodes;
  27
  28 auto node1 = Layer::create():
  29 auto node2 = Layer::create():
  30 auto node3 = Layer::create():
  31 auto node4 = Layer::create():
  32
  33 nodes.insert("node_1", node1)
  34 nodes.insert("node_2", node1)
  35 nodes.insert("node_3", node1)
  36 nodes.insert("node_4", node1)
  37 </pre>
