Scan barcodes in iOS7 with elegance and ease

iOS7 provides barcode scanning as part of the AV Framework, but it takes some work to figure it all out and then set it up to be efficient and robust. TFBarcodeScanner makes it super easy: create a view controller subclass of TFBarcodeScannerViewController, override barcodeWasScanned, and you are scanning barcodes!

We recommend using CocoaPods to install TFBarcodeScanner. Add to your Podfile:

pod 'TFBarcodeScanner'

To install manually, add TFBarcodeScanner to your project as a subproject, and then add the TFBarcodeScanner static library in your project's Build Phases.

1. Create a view controller that is subclassed from TFBarcodeScannerViewController. Make sure that your subviews have a transparent region so the preview is visible.
2. In your viewDidLoad method, optionally set the barcodeTypes bit flag to whatever barcode types you want to scan.
3. Override the barcodeWasScanned method. This returns a set of barcodes that were recognized. You normally will call stop once a suitable barcode is recognized.
4. If you have UI elements that you want to overlay on top of the scanning preview, override barcodePreviewWillShowWithDuration and show the elements in this method. You will also want to override barcodePreviewWillHideWithDuration to hide these same elements.
