Undefined symbols for architecture armv7:
"_OBJC_CLASS_$_MPMusicPlayerController", referenced from: objc-class-ref in liblibPDRCore.a(PGDeviceStatus.o) ld: symbol(s) not found for architecture armv7 clang: error: linker command failed with exit code 1 (use -v to see invocation)
One of my lib was manually dragged into project before now I have it installed by cocoapods ,then the problem occurred. And I tried add the MediaPlayer.framework(although I don't need this framework before) to my project,the problem becomes this : ld: 14 duplicate symbols for architecture armv7
Anyone can help me ?????
