# Reorder [](https://travis-ci.org/pikachu987/Reorder) [](http://cocoapods.org/pods/Reorder) [](http://cocoapods.org/pods/Reorder) [](http://cocoapods.org/pods/Reorder)   ## Introduce |UITableView|UICollectionView|MultipleSection| |---|---|---| |<img src="./images/table.gif" width="200px">|<img src="./images/collection.gif" width="200px">|<img src="./images/section.gif" width="200px">| ## Requirements `Reorder` written in Swift 5.0. Compatible with iOS 9.0+ ## Installation ### Cocoapods Reorder is available through [CocoaPods](https://cocoapods.org). To install it, simply add the following line to your Podfile: ```ruby pod 'Reorder' ``` ## Usage ### UITableView ```swift class TableViewController: UIViewController { let tableView = UITableView(frame: .zero, style: .plain) var list = [[Int]]() override func viewDidLoad() { super.viewDidLoad() self.tableView.delegate = self self.tableView.dataSource = self self.tableView.reorder.delegate = self } } // MARK: TableViewReorderDelegate extension TableViewController: TableViewReorderDelegate { var reorderSuperview: UIView { return self.navigationController?.view ?? UIView() } func tableViewReorder(_ tableView: UITableView, moveRowAt sourceIndexPath: IndexPath, to destinationIndexPath: IndexPath) { if sourceIndexPath.section == destinationIndexPath.section { // Row self.list[sourceIndexPath.section].swapAt(sourceIndexPath.row, destinationIndexPath.row) } else { // MultipleSection let sourceItem = self.list[sourceIndexPath.section][sourceIndexPath.row] self.list[sourceIndexPath.section].remove(at: sourceIndexPath.row) self.list[destinationIndexPath.section].insert(sourceItem, at: destinationIndexPath.row) } } func tableViewReorder(_ tableView: UITableView, canMoveRowAt indexPath: IndexPath) -> Bool { return self.list[indexPath.section][indexPath.row].canMove } } ``` ### UICollectionView ```swift class CollectionViewController: UIViewController { let collectionView = UICollectionView(frame: .zero, collectionViewLayout: Layout()) var list = [[Int]]() override func viewDidLoad() { super.viewDidLoad() self.collectionView.delegate = self self.collectionView.dataSource = self self.collectionView.reorder.delegate = self } } // MARK: CollectionViewReorderDelegate extension MultipleSectionCollectionViewExampleViewController: CollectionViewReorderDelegate { var reorderSuperview: UIView { return self.navigationController?.view ?? UIView() } func collectionViewReorder(_ collectionView: UICollectionView, moveItemAt sourceIndexPath: IndexPath, to destinationIndexPath: IndexPath) { if sourceIndexPath.section == destinationIndexPath.section { // Item let item = self.list[sourceIndexPath.section][sourceIndexPath.item] self.list[sourceIndexPath.section].remove(at: sourceIndexPath.item) self.list[sourceIndexPath.section].insert(item, at: destinationIndexPath.item) } else { // MultipleSection let sourceItem = self.list[sourceIndexPath.section][sourceIndexPath.row] self.list[sourceIndexPath.section].remove(at: sourceIndexPath.row) self.list[destinationIndexPath.section].insert(sourceItem, at: destinationIndexPath.row) } } } ``` ### Move Auto Scroll <img src="./images/scroll.gif" width="200px"> ```swift self.tableView.reorder.scrollFrame = CGRect(x: 0, y: 88, width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height - 88) self.collectionView.reorder.scrollFrame = CGRect(x: 0, y: 88, width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height - 88) ``` ### Can't Move <img src="./images/move.gif" width="200px"> ```swift // MARK: TableViewReorderDelegate extension ExampleViewController: TableViewReorderDelegate { func tableViewReorder(_ tableView: UITableView, canMoveRowAt indexPath: IndexPath) -> Bool { return self.list[indexPath.row].canMove } } ``` ### Property ##### Scale Snapshot view size on cell touch ```swift enum Scale { case custom(CGFloat) case none case small case medium case large } ``` ##### OverlapBehaviour The amount of overlap with other cells when moving a cell ```swift public enum OverlapBehaviour { case oneThird case half case twoThirds } ``` ### Delegate ```swift protocol ReorderDelegate: class { var reorderSuperview: UIView { get } func reorderBegan() func reorderChanged() func reorderEnded() } protocol CollectionViewReorderDelegate: ReorderDelegate { func collectionViewReorder(_ collectionView: UICollectionView, moveItemAt sourceIndexPath: IndexPath, to destinationIndexPath: IndexPath) func collectionViewReorder(_ collectionView: UICollectionView, canMoveItemAt indexPath: IndexPath) -> Bool } protocol TableViewReorderDelegate: ReorderDelegate { func tableViewReorder(_ tableView: UITableView, moveRowAt sourceIndexPath: IndexPath, to destinationIndexPath: IndexPath) func tableViewReorder(_ tableView: UITableView, canMoveRowAt indexPath: IndexPath) -> Bool } ``` ### Protocol Select the view for which you want to create a snapshop. Is optional. If you don't adopt ReorderCell, make the contentView a snapshot. ```swift class TableViewCell: UITableViewCell, ReorderCell { private let reorderView = UIView() var reorderSnapshotView: UIView { return self.reorderView } } ``` ## Author pikachu987, pikachu77769@gmail.com ## License Reorder is available under the MIT license. See the LICENSE file for more info.
