任何想法如何解决这个问题？我已经尝试了2个多小时...
any idea how can i fix this? i have been trying over 2 hours already...
我已经下载了其他示例，但我仍然得到相同的链接器错误。
I have downloded other examples but i m still getting the same linker error.
感谢任何帮助......
Appreciate any help...
推荐答案
我遇到了和你一样的错误，我的问题是我有未添加QuartzCore框架（选择项目目标，展开使用库链接二进制文件，单击+选择QuartzCore.framework）。
I got the same error as you and my problem was that I had not added the QuartzCore framework (select your project target, expand "Link binaries with libraries", click '+' to select QuartzCore.framework).
