## What it is
An Objective-C library providing a TableViewController subclass that adds pull-to-refresh functionality to iPhone apps, inspired by Tweetie 2. It is now obsolete since Apple's native UIRefreshControl covers this need from iOS 6 onward.

## Use cases
- add pull-to-refresh to a UITableView in an old iOS app
- support refresh-on-pull on iOS versions before 6.0
- customize a pull-to-refresh table view controller
- replicate Tweetie-style refresh interaction
- learn how pull-to-refresh was implemented in Objective-C

## When to choose
- you must support iOS versions older than 6.0
- you maintain a legacy Objective-C codebase already using it
- you want a minimal, copy-in implementation to study or modify

## When to avoid
- you target iOS 6.0 or later - use UIRefreshControl instead
- you want an actively maintained library
- you are starting a new Swift or SwiftUI project

## Facets

- maturity: abandoned
