iOS開發筆記－File is universal (2 slices) but does not contain a(n) armv7s slice

今天在Build以前正常可用的project時，發生以下的問題：

(null): File is universal (2 slices) but does not contain a(n) armv7s slice: iOS/CorePlot_1.0/Binaries/iOS/libCorePlot-CocoaTouch.a for architecture armv7s

看來換成新的xCode依然是問題不少，每次換都有新發現，總之，如下圖，將Build Active Architecture Only改成Yes即可。

看來libCorePlot-CocoaTouch.a的使用只能在armv7以下，這次多了armv7s，所以才有問題

參考網頁：

Why am I seeing the following linker errors when building an iPhone app with Core Plot?
