NVPullToRefresh

PullToRefresh + NVActivityIndicatorView

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Installation

NVPullToRefresh is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'NVPullToRefresh'

Animation types

Get started

Import NVPullToRefresh

    import NVPullToRefresh

    var refresher = NVPullToRefresh(NVActivityIndicatorType: .circleStrokeSpin, Color: .black)
    
    tableView.addPullToRefresh(refresher) {
            //Do Your Thing Here.
        }

The easiest way to create PullToRefresh:

  let refresher = NVPullToRefresh()

It will create a default pull-to-refresh with a simple view which has single UIActivitiIndicatorView. To add refresher to your UIScrollView subclass:

tableView.addPullToRefresh(refresher) {
    // action to be performed (pull data from some source)
}

⚠️ Don't forget to remove pull to refresh when your view controller is releasing. ⚠️

deinit {
tableView.removePullToRefresh(tableView.topPullToRefresh!)
}

After the action is completed and you want to hide the refresher:

tableView.endRefreshing()

You can also start refreshing programmatically:

tableView.startRefreshing()

But you probably won’t use this component, though. UITableViewController and UICollectionViewController already have a simple type of refresher. It’s much more interesting to develop your own pull-to-refresh control.

Usage in UITableView with sections

Unfortunaly, UITableView with sections currently not supported. But you can resolve this problem in two steps:

1. Create you own PullToRefresh (see instructions below).
2. Set its shouldBeVisibleWhileScrolling property to true. It makes you PullToRefresh always visible while you're scrolling the table.
