admob集成中的可达性错误

Question

I am trying to integrate admob in my ios application but I am getting following errors when I add sdk and build it.

Undefined symbols for architecture i386:
  "_SCNetworkReachabilityCreateWithName", referenced from:
      -[GADNetworkChecker startNetworkChecking] in libGoogleAdMobAds.a(GADNetworkChecker.o)
  "_SCNetworkReachabilityScheduleWithRunLoop", referenced from:
      -[GADNetworkChecker startNetworkChecking] in libGoogleAdMobAds.a(GADNetworkChecker.o)
  "_SCNetworkReachabilitySetCallback", referenced from:
      -[GADNetworkChecker startNetworkChecking] in libGoogleAdMobAds.a(GADNetworkChecker.o)
  "_SCNetworkReachabilityUnscheduleFromRunLoop", referenced from:
      -[GADNetworkChecker stopNetworkChecking] in libGoogleAdMobAds.a(GADNetworkChecker.o)
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I have included all required framework including SystemConfiguration, CFNetwork etc.

Update

I am getting this error when I build in simulator but not when I build with device. is it sdk issue? I am using simulator 5.1.

Make sure that the frameworks that you added are correctly linked under the "Link Binary With Libraries" section of your Build Settings. Also, look at "Compile Sources" under "Build Phases" to make sure all of the relevant files you want to compile are there.
