JXCategoryView
JXCategoryView is a set of iOS user interface components for creating scrollable tab menus and paging containers. It provides a system for implementing category-based navigation where a segmented control coordinates with a content area to enable section transitions.
The project focuses on the synchronization between a navigation menu and a paging view controller, ensuring that scrolling through content updates the active tab and vice versa. It supports highly customizable tab cells through subclassing, allowing for the integration of images, rich text, and notification badges.
The library includes capabilities for lazy-loading child view controllers to manage memory and startup time. It also provides logic for gesture coordination to resolve conflicts between the navigation menu and system gestures, such as restricting the edge-swipe back navigation.
Features
- Category Navigation Interfaces - Provides a scrollable top-level menu for switching between different content sections.
- Navigation Tabs - Provides a scrollable top-level navigation menu for switching between different content sections via customizable tabs.
- Segmented Control Systems - A customizable selection bar that manages category switching with animated indicators and support for custom cells.
- Segmented Controls - Implements a segmented control for switching between multiple content views with synchronized scrolling.
- iOS Paging View Controllers - Provides a container for coordinating child view controllers with a category menu for seamless section transitions.
- iOS UI Components - Provides reusable iOS-specific UI components for building scrollable category navigation.
- View Controller - Optimizes memory and startup time by instantiating child view controllers only when their tab becomes active.
- UI Navigation Coordination - Coordinates synchronization between category views and scroll views to ensure aligned navigation and paging.
- Segmented Control Renderers - Implements a segmented control interface used to navigate between different content sections or pages.
- Scroll Synchronization - Synchronizes the category menu with a paging view so that scrolling content updates the active tab.
- Synchronized Content Paging - Linking a category menu with a paging view so that scrolling through content updates the active tab.
- Synchronized Scroll Containers - Synchronizes the scroll offsets of the horizontal menu and the paging container.
- Mobile UI Components - Provides customizable mobile UI components including tabs with icons and notification badges.
- Deferred View Controller Loading - Defers the initialization of child views or controllers until their corresponding tab becomes visible.
- Category Item Displays - Customizable display options for category items, including multi-line text and individual cell updates for UI elements.
- DataSource-Driven Cell Rendering - Implements a data-driven approach to render navigation tabs using a data source to populate custom cells.
- Cross-Component Gesture Coordination - Manages interactions between the category view and other gesture recognizers to prevent navigation conflicts.
- Gesture Conflict Resolution - Provides logic to resolve conflicts between the navigation scroll view and system gestures like the back-swipe.
- Navigation Controllers - Provides programmatic control over content transitions and item selection for switching between views.
- Component Lifecycle Management - Manages resource allocation and UI updates when list views enter or leave the screen.
- View Controller Lifecycle Management - Manages the lifecycle events of child view controllers as they are selected or scrolled into view.
- Dynamic Tab Data Updates - Allows updating tab titles and states from a data source without reloading the entire content container.
- Custom Cell Subclassing - Allows developers to override the base cell class to create custom layouts with rich text and images.
- Deferred Loading - Implements deferred loading of child view controllers to improve application startup speed.
