reusableprotocol's Introduction

ReusableProtocol

🎏 ReusableProtocol is a helpful and pure Swift implemented library for registering and reusing cells or views in the table view and collection view. You may never care about what the reuse identifier is.

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Requirements

iOS 8.0+

Installation

ReusableProtocol is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'ReusableProtocol'

Usage

// UITableView
tableView.register(TableViewCell.self)
tableView.register(TableViewHeaderView.self)

// UICollectionView
collectionView.register(CollectionViewCell.self)
collectionView.register(CollectionHeaderView.self,
                        forSupplementaryViewOfKind: UICollectionView.elementKindSectionHeader)

Dequeue the cell or view:

// UITableView
let cell = tableView.dequeueReusableCell(with: TableViewCell.self, for: indexPath)
let view = tableView.dequeueReusableHeaderFooterView(with: TableViewHeaderView.self)

// UICollectionView
let cell = collectionView.dequeueReusableCell(with: CollectionViewCell.self, for: indexPath)
let view = collectionView.dequeueReusableSupplementaryView(ofKind: kind, 
                                                           viewClass: CollectionHeaderView.self,
                                                           for: indexPath)

Optional: You may want to register the cell or view from nib:

// UITableView
tableView.register(TableViewCell.self, fromNib: true)
tableView.register(TableViewHeaderView.self, fromNib: true)

// UICollectionView
collectionView.register(CollectionViewCell.self, fromNib: true)
collectionView.register(CollectionHeaderView.self, 
                        forSupplementaryViewOfKind: UICollectionView.elementKindSectionHeader,
                        fromNib: true)
