how to use zbar sdk in universal application(iphone and ipad)?

I am creating the universal application(iPhone and iPad). In my application, i used ZBar SDK for barcode scanning. While running the application in iPhone it's working fine. But in iPad the application is not opening. In console it shows the error,

dyld: Symbol not found: _CFXMLNodeGetInfoPtr Referenced from: /System/Library/Frameworks/Security.framework/Versions/A/Security Expected in: /ios 4/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.2.sdk/System/Library/Frameworks/CoreFoundation.framework/CoreFoundation in /System/Library/Framework开发者_运维问答s/Security.framework/Versions/A/Security

Please refer me is there any solution?

If you read your error message closely, it says it expected to find a symbol (_CFXMLNodeGetInfoPtr) in a particular framework (Security.framework). Did you add this framework to your project properly?

You have to add these system frameworks to your project:

• AVFoundation.framework
• CoreMedia.framework
• CoreVideo.framework
• QuartzCore.framework
• libiconv.dylib
