LOCAL_SRC_FILES := hellocpp/main.cpp \
../../Classes/AppDelegate.cpp \
../../Classes/HelloWorldScene.cpp
只要把上面这些替换成下面的：
SRC_FILES := hellocpp/main.cpp
SRC_FILES += $(wildcard $(LOCAL_PATH)/../../Classes/*.cpp)
SRC_FILES += $(wildcard $(LOCAL_PATH)/../../Classes/*/*.cpp)
SRC_FILES += $(wildcard $(LOCAL_PATH)/../../Classes/*/*/*.cpp)
SRC_FILES += $(wildcard $(LOCAL_PATH)/../../Classes/*/*/*/*.cpp)
LOCAL_SRC_FILES := $(SRC_FILES:$(LOCAL_PATH)/%=%)
就搞定了 以后你就放心的写cpp去吧，再也不用每次就手写导入了
