pod 'CRRefresh'Second, install CRRefresh into your project:
pod installCarthage
Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks. To integrate CRRefresh into your Xcode project using Carthage, specify it in your Cartfile:
github "CRAnimation/CRRefresh"
Run carthage update to build the framework and drag the built CRRefresh.framework (in Carthage/Build/iOS folder) into your Xcode project (Linked Frameworks and Libraries in Targets).
Manually
- Download the latest code version .
- Open your project in Xcode,drag the
CRRefreshfolder into your project. Make sure to select Copy items when asked if you extracted the code archive outside of your project. - You need it with
import CRRefresh.
Usage
Add CRRefresh to your project
import CRRefreshAdd pull-to-refresh
/// animator: your customize animator, default is NormalHeaderAnimator
tableView.cr.addHeadRefresh(animator: NormalHeaderAnimator()) { [weak self] in
/// start refresh
/// Do anything you want...
DispatchQueue.main.asyncAfter(deadline: .now() + 2, execute: {
/// Stop refresh when your job finished, it will reset refresh footer if completion is true
self?.tableView.cr.endHeaderRefresh()
})
}
/// manual refresh
tableView.cr.beginHeaderRefresh()Add infinite-scrolling
/// animator: your customize animator, default is NormalFootAnimator
tableView.cr.addFootRefresh(animator: NormalFootAnimator()) { [weak self] in
/// start refresh
/// Do anything you want...
DispatchQueue.main.asyncAfter(deadline: .now() + 2, execute: {
/// If common end
self?.tableView.cr.endLoadingMore()
/// If no more data
self?.tableView.cr.noticeNoMoreData()
/// Reset no more data
self?.tableView.cr.resetNoMore()
})

/// The height of the animation is executed
var execute: CGFloat {set get}
/// Start refresh
mutating func refreshBegin(view: CRRefreshComponent)
/// End refresh
mutating func refreshEnd(view: CRRefreshComponent, finish: Bool)
/// Refresh the progress changes
mutating func refresh(view: CRRefreshComponent, progressDidChange progress: CGFloat)
/// Refresh the state changes
mutating func refresh(view: CRRefreshComponent, stateDidChange state: CRRefreshState)
}Remove
tableView.cr.removeFooter()
tableView.cr.removeHeader()Contribution
