就是想试试自己做的游戏对不同分辨率的屏幕适应度如何，本来可以适配iphone 4，我切换到iphone 5s，调整了一些东西，再换回 iphone 4，就一堆link error。现在无论调到哪种设备，都是一堆link error，有人有过相同经历吗？
版本：xcode 6.0 cocos2dx 3.2
错误信息：节选…

补充一下，可能这个也有用。
在所有的error上面有三个warning，如下

啊… 又自己逗自己玩了。
不知道为什么在编完iphone4s之后再选择iphone5s， 项目会重新编译，但是再换回4s后项目有些.o文件不会重新编译，导致链接失败
其实make clean一下就好了。。
解决掉了。。
不会重新编译==>那是因为文件源码没有更新！
编完4s再选择5s会重新编译，可能是因为编译参数发生变化，导致自动自动调用了clean动作。具体得看一下Makefile文件，应该就能知道了。
是否会重新编译，这些都是Makefile的知识罢了，跟什么4s与5s是没有关系的。
