We are using Zbar bar code reader from last 2 years. With iOS 7 and Xcode 5, after scanning 5 bar codes the app is reaching 100 % cpu use for iOS 7 device(I can see that in Xcode debug mode) and app become less responsive. We never had issue in earlier iOS versions, everything worked fine. Is thing changed in iOS 7 related to camera launching and ZBar SDK is not updated? Is anyone else facing same
