Useage

What is a container? A container is the object that hold the scrollView reference, most time it is a UIViewController object

Pull down to refresh

self.tableView.configRefreshHeader(container:self) { [weak self] in
    // success
    self?.tableView.switchRefreshHeader(to: .normal(.success, 0.5))
    // failure
    self?.tableView.switchRefreshHeader(to: .normal(.failure, 0.5))
    
    // if no more data
    self?.tableView.switchRefreshFooter(to: .removed)
}

Pull up to load more

Support three mode to fire refresh action

• Tap
• Scroll
• Scroll and Tap

self.tableView.configRefreshFooter(container:self) { [weak self] in
	// has more data
    self?.tableView.switchRefreshFooter(to: .normal)
    // no more data
    self?.tableView.switchRefreshFooter(to: .removed)
};

Pull left to exit

scrollView.configSideRefresh(with: DefaultRefreshLeft.left(), container:self, at: .left) {
    self.navigationController?.popViewController(animated: true)
};

Pull right to Pop

let right  = DefaultRefreshRight.right()
right.setText("👈滑动关闭", mode: .scrollToAction)
right.setText("松开关闭", mode: .releaseToAction)
right.textLabel.textColor = UIColor.orange
scrollView.configSideRefresh(with: right, container:self, at: .right) { [weak self] in
    self?.navigationController?.popViewController(animated: true)
};

Config the default refresh text

YLPullToRefreshKit offer SetUp operator，for example

let header = DefaultRefreshHeader.header()
header.setText("Pull to refresh", mode: .pullToRefresh)
header.setText("Release to refresh", mode: .releaseToRefresh)
header.setText("Success", mode: .refreshSuccess)
header.setText("Refreshing...", mode: .refreshing)
header.setText("Failed", mode: .refreshFailure)
header.tintColor = UIColor.orange
header.imageRenderingWithTintColor = true
header.durationWhenHide = 0.4
self.tableView.configRefreshHeader(with: header,container:self) { [weak self] in
    delay(1.5, closure: {
        self?.models = (self?.models.map({_ in random100()}))!
        self?.tableView.reloadData()
        self?.tableView.switchRefreshHeader(to: .normal(.success, 0.3))
    })
};

Customize

You just need to write a UIView sub class,and make it conforms to these protocols

• RefreshableHeader
• RefreshableFooter
• RefreshableLeftRight

For exmaple,to create a custom header

    //Height of the refresh header
    func heightForHeader()->CGFloat
    
    //Distance from top when in refreshing state
    func heightForRefreshingState()->CGFloat
   
    //Will enter refreshing state,change view state to refreshing in this function
    func didBeginrefreshingState()

    //The refreshing task is end.Refresh header will hide.Tell user the refreshing result here.
    func didBeginHideAnimation(result:RefreshResult)
    
    //Refresh header is hidden,reset all to inital state here
    func didCompleteHideAnimation(result:RefreshResult)
    
    //Distance to drag to fire refresh action ,default is heightForRefreshingState
    optional func heightForFireRefreshing()->CGFloat
    
    //Percent change during scrolling
    optional func percentUpdateDuringScrolling(percent:CGFloat)
    
    //Duration of header hide animation
    optional func durationOfHideAnimation()->Double
