Currently, I am revitalizing Sudoku Grab, my first app ever, published in 2009. The plan involves updating the code, upgrading to ARC, simplifying the menu system, accommodating iOS7, and supporting 4-inch display sizes. Future updates may include iCloud syncing features for universal access to puzzles. This endeavor also gives me an excuse to switch to an iPhone5s!
In iOS7, a previously unannounced feature allows the ability to read barcodes. Incorporating a new output for AVCapture known as AVCaptureMetadataOutput, supported formats for 1D and 2D barcodes can be read. Demonstrating the ease of use, a simple code snippet is provided to showcase how to apply this feature. Additionally, a demo project is shared for those keen to explore its functionality.
