SwiftPullToRefresh

An easy way to implement pull-down-to-refresh and pull-up-to-load-more feature based on UIScrollView extension, written in Swift 3.

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

Text Header

Text, font, color can be customized.

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

Small GIF Header

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

GIF + Text Header

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

Big GIF Header

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

SuperCat Header (Inspired by RayWenderlich)

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

Indicator Footer

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

Text Footer

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

Customization

The framework is very easy to customize the use.

You just need to subclass the RefreshHeaderView or RefreshFooterView and implement the methods below, then call spr_addCustomHeader(headerView:) or spr_addCustomHeader(headerView:) to add it to your scrollView.

class CustomHeader: RefreshHeaderView {
    override func updateRefreshState(_ isRefreshing: Bool) {
        // customize your view display with refresh state here
    }
    
    override func updateProgress(_ progress: CGFloat) {
        // customize your view display with progress here
    }
}

class CustomFooter: RefreshFooterView {
    override func updateRefreshState(_ isRefreshing: Bool) {
        // customize your view display with refresh state here
    }
    
    override func updateProgress(_ progress: CGFloat) {
        // customize your view display with progress here
    }
}
