Apple Mach-O linker error: Undefined symbols for architecture armv7

I'm fairly new to the coding world but I've been picking up on things real quick. However, this issue has me beat - I've tried looking through several forums to find out what the problem is but so far no dice. I keep getting two linker errors when ONY when I try to run an app on my device - it works fine in the simulator with no errors. Here's the log:

undefined symbols for architecture armv7:
  "_NewBase64Encode", referenced from:
      -[NSData(Base64) base64EncodedString] in nsdata_and_base64.o
  "_NewBase64Decode", referenced from:
  +[NSData(Base64) dataFromBase64String:] in nsdata_and_base64.o
  _checkReceiptSecurity in verification_controller.o
ld: symbol(s) not found for architecture armv7
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Anyone got any ideas as to what the problem may be? Help would be much appreciated..

Thanks!!

You are using lib that is compiled for simulator (i386 architecture).
You need find lib or build it if you have source code for iOS device.
BTW: NSData supports base64 encoding:
- (NSString *)base64Encoding Availability: iOS 4 - iOS 7;
- (NSString *)base64EncodedStringWithOptions:(NSDataBase64EncodingOptions)options Availability: iOS 7 and later.
May be you needn't use external lib at all.
