SwiftReorder

SwiftReorder is a UITableView extension that lets you add long-press drag-and-drop reordering to any table view. It's robust, lightweight, and fully customizable.

Demo

Features

  • Smooth animations
  • Automatic edge scrolling
  • Works with multiple table sections
  • Customizable shadow, scaling, and transparency effects

Installation

CocoaPods

To integrate SwiftReorder into your Xcode project using CocoaPods, specify it in your Podfile:

pod 'SwiftReorder', '~> 6.0'

Carthage

To integrate SwiftReorder into your Xcode project using Carthage, specify it in your Cartfile:

github "adamshin/SwiftReorder" ~> 6.0

Remember to add SwiftReorder to your Carthage build phase:

$(SRCROOT)/Carthage/Build/iOS/SwiftReorder.framework

and

$(BUILT_PRODUCTS_DIR)/$(FRAMEWORKS_FOLDER_PATH)/SwiftReorder.framework

Manually

You can integrate SwiftReorder into your project manually by copying the contents of the Source folder into your project.

Usage

Setup

  • Add the following line to your table view setup.
override func viewDidLoad() {
    // ...
    tableView.reorder.delegate = self
}
  • Add this code to the beginning of your tableView(_:cellForRowAt:).
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    if let spacer = tableView.reorder.spacerCell(for: indexPath) {
        return spacer
    }
    // ...
}
  • Implement the tableView(_:reorderRowAt:to:) delegate method, and others as necessary.
extension MyViewController: TableViewReorderDelegate {
    func tableView(_ tableView: UITableView, reorderRowAt sourceIndexPath: IndexPath, to destinationIndexPath: IndexPath) {
        // Update data model
    }
}

This method is analogous to the UITableViewDataSource method tableView(_:moveRowAt:to:). However, it may be called multiple times in the course of one drag-and-drop action.

Customization

SwiftReorder exposes several properties for adjusting the style of the reordering effect. For example, you can add a scaling effect to the selected cell:

tableView.reorder.cellScale = 1.05

Or adjust the shadow:

tableView.reorder.shadowOpacity = 0.5
tableView.reorder.shadowRadius = 20
