iPhone开发--Unresolved Symbols CAKeyframeAnimation : iOS Animation
我尝试这用CoreAnimation做一些动画效果，却在最后出现了如下的编译错误：
[plain]
Undefined symbols for architecture i386:
"_OBJC_CLASS_$_CAKeyframeAnimation", referenced from:
objc-class-ref in SpellPageViewController.o
ld: symbol(s) not found for architecture i386
collect2: ld returned 1 exit status

解决方法：
检查你是否链接了QuartzCore库，如没有链接，请将其放到frameWork中。
补充：web前端 , JavaScript ,
