No architectures to compile for (ONLY_ACTIVE_ARCH=YES, active arch=x86_64, VALID_ARCHS=i386).

No architectures to compile for (ONLY_ACTIVE_ARCH=YES, active arch=armv7, VA

运行报错

出现的原因：armv7s是应用在iPhone 5 A6 的架构上的
解决的方式：
1，在Project target里“Architectures”设置为“Standard （armv7,armv7s）”
2，修改在Project target里“Build Settings”的“Valid Architectures”添加“i386”和“armv7”(Xcode4.6 以上版本不再支持armv6，请去掉)
3,设置”Build Active Architecture Only”为“NO”。这样你build你的项目的时候就能在iphoe5和iphoe4s里执行。

armv6, armv7, armv7s的区别

 

You can set the "Build Active Architecture Only" and "Archs" values from command line itself. We set ARCHS="armv7 armv7s" ONLY_ACTIVE_ARCH=NO.
