SwiftPullToRefresh

An easy way to implement pull-to-refresh feature based on UIScrollView extension, written in Swift 4.

Provide default style header and footer controls which you can directly use in your project, and also support for customization. GIF is also supported.

Example usage

Indicator Header

scrollView.spr_setIndicatorHeader { [weak self] in
    // do your action here
    // self?.scrollView.spr_endRefreshing()
}

Text Header

scrollView.spr_setTextHeader { [weak self] in
    // do your action here
    // self?.scrollView.spr_endRefreshing()
}

Small GIF Header

scrollView.spr_setGIFHeader(data: data, isBig: false, height: 60) { [weak self] in
    // do your action here
    // self?.scrollView.spr_endRefreshing()
}

GIF + Text Header

scrollView.spr_setGIFTextHeader(data: data) { [weak self] in
    // do your action here
    // self?.scrollView.spr_endRefreshing()
}

Big GIF Header

scrollView.spr_setGIFHeader(data: data, isBig: true, height: 120) { [weak self] in
    // do your action here
    // self?.scrollView.spr_endRefreshing()
}

Indicator Footer

scrollView.spr_setIndicatorFooter { [weak self] in
    // do your action here
    // self?.scrollView.spr_endRefreshing()
}

or

scrollView.spr_setIndicatorAutoFooter { [weak self] in
    // do your action here
    // self?.scrollView.spr_endRefreshing()
}

Text Footer

scrollView.spr_setTextFooter { [weak self] in
    // do your action here
    // self?.scrollView.spr_endRefreshing()
}

or

scrollView.spr_setTextAutoFooter { [weak self] in
    // do your action here
    // self?.scrollView.spr_endRefreshing()
}

Clear header or footer

scrollView.spr_clearHeader()
scrollView.spr_clearFooter()

CocoaPods

Carthage

github "WXGBridgeQ/SwiftPullToRefresh"

Manual

Add SwiftPullToRefresh folder into your project.

Customization

The framework is very easy to customize the use.

You just need to subclass the RefreshView and implement the methods below, then call spr_setCustomHeader(_:) or spr_setCustomFooter(_:) with your scrollView.

class CustomHeaderOrFooter: RefreshView {
    override func didUpdateState(_ isRefreshing: Bool) {
        // customize your view display with refresh state here
    }
    
    override func didUpdateProgress(_ progress: CGFloat) {
        // customize your view display with progress here
    }
}

You can also check the code of the super cat refresh which is a custom header in the SwiftPullToRefreshDemo target (Inspired by RayWenderlich)
