SlackTextViewController
SlackTextViewController is a specialized iOS user interface framework and UIKit text input component designed for markdown editing and messaging input management. It provides a view controller subclass that bundles text input logic and layout management into a reusable component for iOS applications.
The framework implements specific messaging interface behaviors, including inverted scroll layouts that anchor content from the bottom up and animated typing indicators. It supports a rich text input workflow with markdown formatting, prefix-based autocompletion, and the ability to insert images and videos directly from the system clipboard.
The project covers a broad range of interaction capabilities, including dynamic text input resizing, hardware keyboard command mapping, and device-motion triggers for shaking gestures. It also includes mechanisms for switching between standard composing and dedicated editing states.
