admob ios7 error Audio framework

Question

I am integrating admob SDK (the current) in my last application IOS7-Xcode5 and i have a new error (same on new project), i guess i missed something, but i restarted the process many times and the error is still here:

Undefined symbols for architecture armv7:
  "_OBJC_CLASS_$_AVAudioSession", referenced from:
  objc-class-ref in libGoogleAdMobAds.a(GADDevice.o)
  "_AVAudioSessionPortHeadphones", referenced from:
      -[GADDevice audioRouteUsingAVAudioSession] in libGoogleAdMobAds.a(GADDevice.o)
  "_AVAudioSessionPortBuiltInSpeaker", referenced from:
      -[GADDevice audioRouteUsingAVAudioSession] in libGoogleAdMobAds.a(GADDevice.o)

I found how to resolve these errors in adding AudioUnit.framework but a new error appears framework not found AudioUnit... As my best friend Google tell me via stackoverflow, "don't use AudioUnit.framework, it's empty! Now use CoreAudio.framework." But my first error came back...

If someone has the same problem and mainly a solution, i will be grateful :)

PS: i tried -all_load and -ObjC, i linked AudioToolbox, i usually work with frameworks but also with careless mistakes ;) :/

Answer 1

hey add AVFoundation framework, because these classes are included in this framework.
