objective c - Scaning static UIImage using ios ZBar SDK -

I want to scan a static UIImage using Zbar sdk, this gives an error that means ZBarSymbol faucet

I, because it is a subclass of UIMAPP Controller and I do not want to use the UIMAPPC Controller at all because I just want to scan. UIImage that I have a reference in my application .. I searched for this problem allocated but I could not find any help.

I also for ZBarImageScanner Tried,
