## What it is
BarrageRenderer is an open-source iOS library for rendering danmaku (bullet comments/barrage) overlays on top of any UIView, written in Objective-C. It provides scrolling and floating barrage sprites with customizable styling, automatic track allocation, time synchronization, and extensible animation interfaces.

## Use cases
- add scrolling bullet comments to a video player in an iOS app
- render floating danmaku overlays over any UIView
- display image and rich text barrage messages
- replay barrage at fixed timestamps for recorded video
- customize danmaku font, color, border, and background
- pause, resume, and speed-adjust barrage animation

## When to choose
- you need danmaku/bullet-comment rendering in an iOS app
- you want a mature Objective-C barrage engine with CocoaPods support
- you need customizable scrolling and floating barrage with track management

## When to avoid
- you are building for Android or web (use DanmakuFlameMaster or web solutions instead)
- you need a Swift-native or SwiftUI barrage implementation
- you need cross-platform danmaku rendering
