ImageGallery is an iOS application built using UIKit. It leverages advanced iOS features allowing users to store and manage images from the internet. Users can drag and drop images into a CollectionView-based gallery. The application provides persistent document handling with full support for creating, naming, opening, and arranging Image Gallery documents.
- Model-View-Controller: This design approach was selected to delineate the Model from the View, thereby improving maintainability and scalability. It ensures a clean separation of concerns, making the application easier to extend and maintain.
- Drag and Drop: Provides an intuitive interface for users to interact directly with images, enhancing user engagement and simplifying the UI.
- CollectionView: Utilizes a robust grid layout to present images in an organized manner, making optimal use of screen real estate.
- ScrollView: Empowers users with smooth navigation, allowing them to zoom and pan through galleries for a better viewing experience.
- Multithreading: Implements concurrent programming to manage image fetching and caching, ensuring that the UI remains responsive at all times.
- URLCache: Employed to cache images locally, which reduces network usage and provides a faster, seamless user experience even when offline.
- Codable: Used for its straightforward and efficient way of encoding and decoding model objects into JSON, simplifying data persistence.
- FileManager: Leveraged for its local document management capabilities, ensuring data persistence and document integrity.
- UIDocument: Integrates seamlessly with iOS's document model, providing a familiar and consistent document handling experience across iOS platforms.
- UIDocumentBrowserViewController: Offers a full document browsing experience, aligning with the native iOS file management workflow.
