ld: file is universal (2 slices) but does not contain a(n) armv7s slice: /Users/douglasjmerritt/Desktop/Xcode 4.5/BlueQuadCalc copy/libCorePlot-CocoaTouch.a for architecture armv7s
clang: error: linker command failed with exit code 1 (use -v to see invocation)
This error did not allow me to run on my iPad. So I did a bit of searching and found that I have to change the Build Active Architecture Only to YES. After that, it all worked fine. This setting is in the build setting. Hope this helps someone!
