I got an error message while I follow the tutorial in my XCode7.1 with iOS9.1. The error is listed as below:
Undefined symbols for architecture x86_64:
“OBJC_CLASS$_BEBase64” referenced from
objc-class-ref in backendless.a(MessagingService.o)
objc-class-ref in backendless.a(OfflineModeManager.o)
ld: symbol(s) not found for architecture x86_64
clang: error: linker comnmand failed with exit code 1
could you help? Thanks !
