在使用下拉刷新类库EGORefreshTableHeaderView的时候,将资源文件添加到工程中,但是忘记假如QuartzCore.framework框架,造成编译错误:

ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
解决方法:targets——>build phases——>link binary with libraries——>QuartzCore.framework
当添加其他类库的时候也可能因为没有添加framework或者是它们依赖的库同样也会出现这样错误。
