CocoaPods で GHUnit と OCMock を追加してエミュレータで動かそうとしたら Linker Error が出た

iOS

CocoaPodsでGHUnit + OCMockなiOS開発環境を構築する - mtgto's diary
CocoaPodsの導入からGHUnitとOCMockのinstallとかは↑これを参考にして作業しました。

実機ビルドは普通に通るのに、エミュレータだと通らなかったので困った。

解決法は、Linked Framework and Libraries に QuartzCore.framework を追加するだけ。

一応Error全文載せた。
