如图
“GameLayer::GameLayer()”, referenced from:
GameLayer::create() in GameScene.o
“vtable for HelloWorld”, referenced from:
HelloWorld::HelloWorld() in HelloWorldScene.o
NOTE: a missing vtable usually means the first non-inline virtual member function has no definition.
“vtable for ControlLayer”, referenced from:
ControlLayer::ControlLayer() in ControlLayer.o
求救
