Try this ways:
1) if you use also use the Facebook SDK look at this question. The solution seems to be:
Add to your AppDelegate.m or another class following constant after
imports and before implementation section: NSString *const
BFTaskMultipleExceptionsException = #"BFMultipleExceptionsException";
2) check your Library Search Paths Flag, maybe you have old reference no more present in your project.
3) remove the -ObjC flag in Other Linker Flags on Build Settings.
