## What it is
LYEmptyView is an iOS library that adds empty-state placeholder views (no data, no network) to UITableView/UICollectionView with a single line of code. It uses categories and runtime method swizzling to automatically show or hide the placeholder based on the data source.

## Use cases
- show a no-data placeholder when a table view is empty
- display a no-network empty state in a collection view
- add retry button to empty state view
- integrate empty view without delegates or protocols
- customize empty state image, title, and detail text
- auto-hide empty placeholder when data loads

## When to choose
- you build iOS apps in Objective-C or Swift with UIKit table/collection views
- you want zero-coupling, one-line empty state integration
- you need automatic show/hide tied to reloadData, insert, and delete calls

## When to avoid
- you use SwiftUI and need native empty states
- you need Auto Layout support for fully custom empty views
- the project is no longer actively maintained and you need ongoing updates
