Why: Armv7s is applied to the architecture of the iphone 5 A6
The way to resolve:
1, "Architectures" is set to "standard (armv7,armv7s)" in Project target
2, modify the "Build Settings" in Project target "Valid architectures" add "i386" and "ARMv7" (Xcode4.6 no longer support ARMV6, please remove)
3, set "Build Active Architecture only" to "NO". This allows you to build your project and execute it in IPHOE5 and iphoe4s.

The difference between armv6, ARMV7, armv7s
