Features

  • Simple and easy to use.
  • Customize loading view whatever you want.

Usage

Basic

Add codes below and add it to UITableView with srf_addRefresher. The closure will be called when refresh starts.

let refresher = RefresherView { [weak self] () -> Void in
    self?.updateItems()
}
tableView.srf_addRefresher(refresher)

And call srf_endRefreshing() whenever/wherever your refreshing task finished.

s.tableView.srf_endRefreshing()

Use with a little Customize

The view of SwiftRefresher is independent from its main system. The only requirement is to conform to SwfitRefresherEventReceivable protocol. Default view is SimpleRefreshView. You can use it with a little customization like this below:

let refresher = Refresher { [weak self] () -> Void in
    self?.updateItems()
}
refresher.createCustomRefreshView { () -> SwfitRefresherEventReceivable in
    return SimpleRefreshView(activityIndicatorViewStyle: .White)
}
tableView.srf_addRefresher(refresher)

In this example, I changed SimpleRefreshView's activityIndicatorViewStyle to .White. But you can customize more with create your own refreh view!

Customize!!!

Just create a view with conforming to SwfitRefresherEventReceivable. SwfitRefresherEventReceivable has one required function func didReceiveEvent(event: SwiftRefresherEvent). Through this function, refresher send the view the events. The events are below:

public enum SwiftRefresherEvent {
    case Pull(offset: CGPoint, threshold: CGFloat)
    case StartRefreshing
    case EndRefreshing
    case RecoveredToInitialState
}

For example, preset SimpleRefreshView has this easy codes.

public func didReceiveEvent(event: SwiftRefresherEvent) {
    switch event {
    case .Pull:
        pullingImageView.hidden = false
    case .StartRefreshing:
        pullingImageView.hidden = true
        activityIndicatorView.startAnimating()
    case .EndRefreshing:
        activityIndicatorView.stopAnimating()
    case .RecoveredToInitialState:
        break
    }
}

RecoveredToInitialState means that after EndRefreshing, the view will go back to initial state. And then the state becamed to the initial, this event will be called.
