问题
I've just upgraded my app to run on the new iPhone5 simulator, however when I try to build it for my iPhone 4S device, I get this Apple Mach-O Liner error.
ld: file is universal (3 slices) but does not contain a(n) armv7s slice: /Users/Darren/Documents/Dev stuff/My App/GoogleAdMobAdsSDKiOS-5.0.5/libGoogleAdMobAds.a for architecture armv7s clang: error: linker command failed with exit code 1 (use -v to see invocation)
Can someone shed some light on what this error it and how to fix it? I am using adWhirl with AdMob.
Thanks
EDIT --- I am also getting this error in another project for the file libfacebook_ios_sdk.a

The same answer as I gave in this thread:
If you want to remove the support for any architecture, try this:
Project -> Build Settings -> remove the architecture from "valid architectures"
You can use this as a temporary solution until the library has been updated. You have to remove the flag from your own project.

iPhone5's cpu is A6(armv7s). The existing Admob sdk does not support it. We have to wait for admob to update the sdk.
回答3:
Update to Admob 6.2.0 or later.
See this post: http://googleadsdeveloper.blogspot.com/2012/09/migrating-to-admob-v62-for-ios.html.
Also, include the AdSupport framework and remove the -all_load flag. You've got to use the -ObjC flag however.
This works for me, finally!!

Try this:
This article copy an armv7 lib code as an armv7s and build into the original lib. so xcode will see that lib has an armv7s code/arch
