首先感谢你的支持，SYRefresh 是一款简洁易用的刷新控件，支持scrolview,Tableview,collectionview刷新功能，具备灵活的扩展功能。
示例程序：
支持pod安装：
pod 'SYRefresh', '~> 1.1.2'
默认刷新控件使用方法：
//添加头部刷新控件
scrollview：
scrollview.sy_header = TextHeader(normalText: "12", pullingText: "222", refreshingText: "333", orientation: .top, height: 60, font: UIFont.systemFont(ofSize: 14), color: UIColor.black, completion: { [weak self] in
DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
self?.scrollview.sy_header?.endRefreshing()
}
})
tableView：
tableView.sy_header = TextHeaderFooter(normalText: "下拉可以刷新", pullingText: "松手即可刷新", refreshingText: "刷新中.....", nomoreDataText: nil, orientation: .top, height: 60, font: UIFont.systemFont(ofSize: 14), color: UIColor.black) {
DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
self.tableView.sy_header?.endRefreshing()
}
}
//添加尾部刷新控件
scrollview：
scrollview.sy_footer = TextHeader(normalText: "12", pullingText: "222", refreshingText: "333", orientation: .bottom, height: 60, font: UIFont.systemFont(ofSize: 14), color: UIColor.black, completion: { [weak self] in
DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
self?.scrollview.sy_footer?.endRefreshing()
}
})
tableView：
tableView.sy_header = TextHeaderFooter(normalText: "下拉可以刷新", pullingText: "松手即可刷新", refreshingText: "刷新中.....", nomoreDataText: “全部加在完成”, orientation: .top, height: 60, font: UIFont.systemFont(ofSize: 14), color: UIColor.black) {
DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
self.tableView.sy_header?.endRefreshing()
}
}
GIF图片刷新控件使用方法：
let data = try! Data(contentsOf: Bundle.main.url(forResource: "giphy.gif", withExtension: nil)!)
tableView.sy_header = GifHeaderFooter(data: data, orientation: .top, height: 100,contentMode:.scaleAspectFill,completion: { [weak self] in
DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
self?.tableView.sy_header?.endRefreshing()
}
})
tableView.sy_footer = GifHeaderFooter(data: data, orientation: .bottom, height: 100,contentMode:.scaleAspectFill,completion: { [weak self] in
DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
self?.tableView.sy_footer?.endRefreshing()
}
})
GIF图片加文字刷新控件使用方法：
let data = try! Data(contentsOf: Bundle.main.url(forResource: "demo-small.gif", withExtension: nil)!)
let textItem = TextItem(normalText: RefreshConfig.headerNomalText, pullingText: RefreshConfig.headerPullingText, refreshingText: RefreshConfig.headerRefreshText, font: UIFont.systemFont(ofSize: 13), color: UIColor.black)
collectionView?.sy_header = GifTextHeaderFooter(data: data,textItem:textItem, orientation: .top, height: 60,contentMode:.scaleAspectFit,completion: { [weak self] in
DispatchQueue.main.asyncAfter(deadline: .now() + 3) {
self?.collectionView?.sy_header?.endRefreshing()
}
})
let textItem2 = TextItem(normalText: RefreshConfig.footerNomalText, pullingText: RefreshConfig.footerPullingText, refreshingText: RefreshConfig.footerRefreshText, font: UIFont.systemFont(ofSize: 13), color: UIColor.black)
collectionView?.sy_footer = GifTextHeaderFooter(data: data,textItem:textItem2, orientation: .bottom, height: 60,contentMode:.scaleAspectFit,completion: { [weak self] in
DispatchQueue.main.asyncAfter(deadline: .now() + 3) {
self?.collectionView?.sy_footer?.endRefreshing()
}
})
传入gif图片数组实现gif播放：
let header = GifImagesHeaderFooter(orientation: .top, height: 80, contentMode: .scaleAspectFit, completion: { [weak self] in
DispatchQueue.main.asyncAfter(deadline: .now() + 2) {
self?.collectionView?.sy_header?.endRefreshing()
}
})
let stateIdleImages = (1..<20).map { index->UIImage in
let imageName = "refresh_camera_frame".appending("\(index)")
let image = UIImage(named: imageName)
return image!
}
let pullingImages = (20..<21).map { index->UIImage in
let imageName = "refresh_camera_frame".appending("\(index)")
let image = UIImage(named: imageName)
return image!
}
let refreshingImages = (21...45).map { index->UIImage in
let imageName = "refresh_camera_frame".appending("\(index)")
let image = UIImage(named: imageName)
return image!
}
header.setRefreshState(state: .stateIdle, images: stateIdleImages)
header.setRefreshState(state: .pulling, images: pullingImages)
header.setRefreshState(state: .refreshing, images: refreshingImages)
collectionView?.sy_header = header
let footer = GifImagesHeaderFooter(orientation: .bottom, height: 60, contentMode: .scaleAspectFit, completion: { [weak self] in
DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
self?.collectionView?.sy_footer?.endRefreshing()
}
})
footer.setRefreshState(state: .stateIdle, images: stateIdleImages)
footer.setRefreshState(state: .pulling, images: pullingImages)
footer.setRefreshState(state: .refreshing, images: refreshingImages)
collectionView?.sy_footer = footer
文字绘制动画：
let textItem = TextItem(normalText: VerticalHintText.headerNomalText, pullingText: VerticalHintText.headerPullingText, refreshingText: VerticalHintText.headerRefreshText, font: UIFont.systemFont(ofSize: 18), color: UIColor.black)
tableView.sy_header = CoreTextHeaderFooter(textItem: textItem, orientation: .top, height: 44,completion: { [weak self] in
DispatchQueue.main.asyncAfter(deadline: .now() + 5) {
self?.tableView.sy_header?.endRefreshing()
self?.count = 15
self?.tableView.reloadData()
}
})
let textItem1 = TextItem(normalText: VerticalHintText.headerNomalText, pullingText: VerticalHintText.headerPullingText, refreshingText: VerticalHintText.headerRefreshText, font: UIFont.systemFont(ofSize: 18), color: UIColor.black)
tableView.sy_footer = CoreTextHeaderFooter(textItem: textItem1, orientation: .bottom, height: 44,completion: { [weak self] in
DispatchQueue.main.asyncAfter(deadline: .now() + 5) {
self?.tableView.sy_footer?.endRefreshing()
self?.count += 15
self?.tableView.reloadData()
}
})
UICollectionView的使用方法同上，如果UICollectionView需要支持水平刷新功能，请设置布局的方向为水平方向即可！
目前还不会支持cocopods，因为它还在起步阶段，等到它功能完善得到大家的认可的时候，我会放到cocopods仓库
如果你在使用中遇到了什么问题，可以直接在讨论区提出，我会及时的解决。
更多功能敬请期待！
