iOS 下拉刷新的加載動畫：BreakOutToRefresh

BreakOutToRefresh 是 iOS 下拉刷新的加載動畫。

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.

Swift 1.2

The code is updated for Swift 1.2. If you like to use it with Xcode 6.1.1 and Swift 1.1 checkout the tag Swift1_1.

Installation

Add BreakOutToRefreshView.swift to your project.

Usage

Add this to your table view controller:

var refreshView: BreakOutToRefreshView!

  override func viewDidLoad() {
    super.viewDidLoad()

    let refreshHeight = CGFloat(100)
    refreshView = BreakOutToRefreshView(scrollView: tableView)
    refreshView.delegate = self

    // configure the colors of the refresh view
    refreshView.scenebackgroundColor = UIColor(hue: 0.68, saturation: 0.9, brightness: 0.3, alpha: 1.0)
    refreshView.paddleColor = UIColor.lightGrayColor()
    refreshView.ballColor = UIColor.whiteColor()
    refreshView.blockColors = [UIColor(hue: 0.17, saturation: 0.9, brightness: 1.0, alpha: 1.0), UIColor(hue: 0.17, saturation: 0.7, brightness: 1.0, alpha: 1.0), UIColor(hue: 0.17, saturation: 0.5, brightness: 1.0, alpha: 1.0)]

    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
  }

}
