有人能告诉我这个错误是什么吗？我正试图在xcode上编译
"_OBJC_CLASS_$_CATransaction", referenced from:
objc-class-ref-to-CATransaction 在RefreshTableViewHeader.o中
而这个错误
"_kCATransactionDisableActions", referenced from:
_kCATransactionDisableActions$non_lazy_ptr在RefreshTableViewHeader.o中
(maybe you meant: _kCATransactionDisableActions$non_lazy_ptr)ld:找不到符号
collect2:ld返回1退出状态
谷歌也于事无补。
我是否缺少任何框架。。。？
