AVLoadingIndicatorView
AVLoadingIndicatorView is a reusable iOS user interface component designed to display background processing states. It specializes in rendering high-quality video files and scalable vector graphics to serve as activity indicators.
The project distinguishes itself by using video content as the primary visual for loading animations instead of standard system spinning animations. It utilizes vector drawing and coordinate transformations to maintain visual sharpness and scaling across different screen resolutions.
The component covers animation visibility control, state transitions, and the visualization of asynchronous processes. It manages these transitions through GPU-accelerated scaling and alpha effects to signal the start and end of data requests.
Features
- Video Based Activity Indicators - Provides a high-quality activity indicator that renders video files instead of standard system animations.
