MTORefresher 是一个 Swift 实现的拉取刷新，包括下拉和上拉。只需一行代码即可实现这一点。您还可以使用 Component 协议来自定义您的拉取刷新组件。
现在支持 Swift 3
pod 'MTORefresher', '~> 1.0.0'
# Optional
pod 'MTORefresher/BasicComponent', '~> 1.0.0'
对于 Swift 2.x
pod 'MTORefresher', '~> 0.1.1'
# Optional
pod 'MTORefresher/BasicComponent', '~> 0.1.1'
// pull down
let topView: SimpleTopComponent = SimpleTopComponent()
// pull up
let bottomView: SimpleBottomComponent = SimpleBottomComponent()
refresher = tableView
.mto_refresher()
.add(topView: topView) { [weak self] in
self?.reload()
}
.add(bottomView: bottomView, enableTap: true) { [weak self] in
self?.loadMore()
}
// hide has bottom view
refresher?.canPullUp = false// trigger pull down
refresher?.triggerLoad(type: .PullDown)
// trigger pull up
refresher?.triggerLoad(type: .PullUp)private func reload() {
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, Int64(0.1*Double(NSEC_PER_SEC))), dispatch_get_main_queue()) {
self.count = 2
self.tableView.reloadData()
// stop loading
self.refresher?.stopLoad()
// show bottom view
self.refresher?.canPullUp = true
self.refresher?.hasMore = true
}
}
private func loadMore() {
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, Int64(0.3*Double(NSEC_PER_SEC))), dispatch_get_main_queue()) {
self.count += 20
self.tableView.reloadData()
// stop loading
self.refresher?.stopLoad()
let hasMore = (rand()%2) == 0 ? true : false
// has more data
self.refresher?.hasMore = hasMore
}
}只需创建一个符合 Componet 协议的子视图。更多请参阅 SimpleTopComponent 和 SimpleBottomComponent！它很容易扩展。
