The Architecture of Nonogram Solver Plus

Nonogram Solver Plus is a highly sophisticated yet user-friendly application designed for the enjoyment and challenge of nonogram puzzles. The app is built on a well-structured architecture, divided into two layers - the back-end that consists of the core logic and structures and the UI that handles all the user interactions.

  1. Backend Layer:

The backbone of Nonogram Solver Plus is the class 'Nonogram', serving as the repository of all logic and necessary mechanics for puzzle resolution. This class and its multiple extensions provide support structures for the nonograms, making it easy to understand, operate, and maintain. This architecture not only encapsulates related functionality but also enhances the app's robustness and modularity.

  1. User Interface Layer:

The UI of the app is made lively through various Controllers and Views, leading to a great user experience. Key classes in this layer include:

  • NonogramSolverViewController: This is the hub of the app's logic. Its responsibility includes managing the user interface and responding to user interactions. It's organized into various extensions based on related functionalities and protocols, ensuring a well-structured and readable codebase.

  • RowClueCollectionViewCell, ColumnClueCollectionViewCell, and GridCellCollectionViewCell: These are custom collection view cell classes, each representing a unique cell in the puzzle grid. They handle the visual aspects of the puzzle cells and clues, providing users with a dynamic and responsive interface to interact with the puzzles.

  • AppDelegate: This class serves as the main entry point of the application and responds to application-level events triggered by the operating system.

Core of Nonogram Solver Plus:

At the heart of the Nonogram Solver Plus application, lies the intelligent and efficient algorithms, integrated with the 'Nonogram' class, enabling the automated resolution of nonogram puzzles. Combined with an elegant UI design, the app provides users with an engaging and seamless puzzle-solving experience.

Nonogram Solver Plus exhibits an effective blend of clever programming and good design principles. The clear division between the backend logic and user interface ensures the application is maintainable and scalable, while also providing a responsive and user-friendly experience.
