This page provides detailed documentation and usage guide for the BVReorderTableView library. BVReorderTableView is a powerful open-source library that allows you to easily add drag-and-drop reordering functionality to your UITableViews in iOS applications.

Getting Started

Requirements

To successfully integrate BVReorderTableView into your iOS project, you need the following:

  • iOS 9.0 or later
  • Xcode 10.0 or later
  • Swift 4.0 or later

Installation

To install BVReorderTableView, you can follow these steps:

  1. Open your project in Xcode
  2. Navigate to the target configuration menu
  3. In the “General” tab, scroll down to “Frameworks, Libraries, and Embedded Content”
  4. Click the “+” button to add a new framework
  5. Select “Add Other”
  6. Navigate to the BVReorderTableView.xcodeproj file in the downloaded BVReorderTableView repository
  7. Select the “BVReorderTableView.framework”
  8. Click “Open”
  9. In the target settings, add the BVReorderTableView.framework to the “Frameworks, Libraries, and Embedded Content” section
  10. Import the BVReorderTableView module in your Swift files where you want to use it

Usage

Basic Implementation

Step 1 – Create Reorder Table View

To begin using BVReorderTableView, you must first create an instance of BVReorderTableView subclass, either programmatically or in Interface Builder.


let reorderTableView = BVReorderTableView(frame: self.view.bounds)
self.view.addSubview(reorderTableView)

Step 2 – Set Delegate and Data Source

Once you have created the reorder table view, you need to set its delegate and data source. Typically, you would set these to the view controller itself.


reorderTableView.delegate = self
reorderTableView.dataSource = self

Step 3 – Implement Data Source Methods

Implement the required methods of the UITableViewDataSource protocol to provide data for the reorder table view.


func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// Return the number of rows in the section
}

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// Create and configure the table view cell
// Return the configured cell
}

Step 4 – Implement Delegate Methods

Implement the delegate methods of BVReorderTableViewDelegate protocol to handle reordering events.


func tableView(_ tableView: UITableView, canMoveRowAt indexPath: IndexPath) -> Bool {
// Return true if the row can be moved, false otherwise
}

func tableView(_ tableView: UITableView, moveRowAt sourceIndexPath: IndexPath, to destinationIndexPath: IndexPath) {
// Perform necessary operations to update the data model when a row is moved
}

Advanced Implementation

BVReorderTableView provides additional features that you can use for more advanced implementation:

  • Customize the appearance and behavior of the reorder handles
  • Support for multiple sections and section headers
  • Disable reordering for specific rows

Conclusion

Congratulations! You have successfully integrated BVReorderTableView into your iOS project. With BVReorderTableView, you can now easily add drag-and-drop reordering functionality to your UITableViews. Enjoy building great user experiences!
