framework

- mediaplayer - coremedia - systemconfiguration - coretelephony - avfoundation - storekit - coremotion - adsupport - foundation - coregraphics - uikit - libc++.dylib - libz.dylib 

setting

architecture              : $(archs_standard_including_64_bit) deployment target         : 7.0 fbaudiencenetwork version : v4.1.0  

additionally, need include bolts.framework using audience network?
after including it, errors gone.
wonder if bolts.framework needed.

(when use fbaudiencenetwork v3.23, these error not occurred)

i found out solution.

i changed project setting.

apple llvm 6.0 - language - modules  : enable modules (c , objective-c) => yes 

hope helpful developers use facebook's audience network.
