BreakOutToRefresh

Play BreakOut while loading - A playable pull to refresh view using SpriteKit

BreakOutToRefresh uses SpriteKit to add a playable mini game to the pull to refresh view in a table view. In this case the mini game is BreakOut but a lot of other mini games could be presented in this space.

Book

If you like this repository and like'd to give me something back, I wrote a book about funny location based projects for iOS. Please check it out: Build Location-Based Projects for iOS

Installation

CocoaPods

Add this to your Podfile:

use_frameworks!

pod 'BreakOutToRefresh'

Manual

Add BreakOutToRefreshView.swift to your project.

Usage

If you need it only once in your app, add this to your table view controller:

class DemoTableViewController: UITableViewController {

  var refreshView: BreakOutToRefreshView!
  
  // ...
  
  override func viewDidLoad() {
    super.viewDidLoad()
    
    refreshView = BreakOutToRefreshView(scrollView: tableView)
    refreshView.refreshDelegate = self
  
    // configure the refresh view
    refreshView.scenebackgroundColor = .white
    refreshView.textColor = .black
    refreshView.paddleColor = .brown
    refreshView.ballColor = .darkGray
    refreshView.blockColors = [.blue, .green, .red]
  
    tableView.addSubview(refreshView)
  }  
}

extension DemoTableViewController: UIScrollViewDelegate {
 
  override func scrollViewDidScroll(scrollView: UIScrollView) {
    refreshView.scrollViewDidScroll(scrollView)
  }
  
  override func scrollViewWillEndDragging(scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>) {
    refreshView.scrollViewWillEndDragging(scrollView, withVelocity: velocity, targetContentOffset: targetContentOffset)
  }
  
  override func scrollViewWillBeginDragging(scrollView: UIScrollView) {
    refreshView.scrollViewWillBeginDragging(scrollView)
  }
}

extension DemoTableViewController: BreakOutToRefreshDelegate {
  
  func refreshViewDidRefresh(refreshView: BreakOutToRefreshView) {
    // load stuff from the internet
  }

}

In case you need it more than once in your app, add the setup to viewWillAppear and clean up in viewWillDisappear like this:

override func viewWillAppear(_ animated: Bool) {
  super.viewWillAppear(animated)
  
  refreshView = BreakOutToRefreshView(scrollView: tableView)
  refreshView.refreshDelegate = self
  
  // configure the refresh view
  refreshView.scenebackgroundColor = .white
  refreshView.textColor = .black
  refreshView.paddleColor = .brown
  refreshView.ballColor = .darkGray
  refreshView.blockColors = [.blue, .green, .red]
  
  tableView.addSubview(refreshView)
}

override func viewWillDisappear(_ animated: Bool) {
  super.viewWillDisappear(animated)
  
  refreshView.removeFromSuperview()
  refreshView = nil
}

When the loading of new content is finished, call endRefreshing() of the refreshView.

When endRefreshing() is called the mini game doesn't stop immediately. The game stops (and the view is dismissed) when the user lifts the finger. If you like to end the mini game immediately set the forceEnd property to true.

Status

It's kind of beta status.

Feedback

If you use this code or got inspired by the idea and build an app with an even more awesome PullToRefresh game, please let me know.
