iPhone开发--Unresolved Symbols CAKeyframeAnimation : iOS Animation

来源:互联网 发布:淘宝不按地址发货 编辑:程序博客网 时间:2024/06/05 09:18

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:

Undefined symbols for architecture i386:  "_OBJC_CLASS_$_CAKeyframeAnimation", referenced from:      objc-class-ref in SpellPageViewController.old: symbol(s) not found for architecture i386collect2: 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。
