关于宏定义与内联函数

//定义了这个宏之后

#define CC_SYNTHESIZE_READONLY(varType, varName, funName)

protected: varType varName;

public: inline virtual varType get##funName(void) const { return varName; }

//执行下面语句

 CC_SYNTHESIZE_READONLY(CANavigationController*, m_pRootNavigationController, RootNavigationController);    

//相当于执行下面这个

 protected:

CANavigationController* m_pRootNavigationController;

inline  CANavigationController* getRootNavigationController(return m_pRootNavigationController;);
