我是
Swift的新手,我想用数组进行无限滚动.这是我的ClassViewController类
class TableViewController: UIViewController,UITableViewDelegate,UITableViewDataSource {
var legumes: [String] = ["Eggs","Milk","Chocolat","Web","Miel","Pop","Eco","Moutarde","Mayo","Thea","Pomelade","Gear","Etc","Nop","Dews","Tout","Fun","Xen","Yoga" ]
override func viewDidLoad() {
super.viewDidLoad()
self.tableView.delegate = self
self.tableView.dataSource = self
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView,numberOfRowsInSection section: Int) -> Int {
return self.legumes.count
}
func tableView(_ tableView: UITableView,cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = self.tableView.dequeueReusableCell(withIdentifier: "Cell",for: indexPath) as! ImageTableViewCell
return cell
}
}
我想显示我的数组的前十项,当我在TableViewController的底部时,它将加载接下来的十个项目,等等.我不知道怎么做,我在GitHub上看到很多代码但是我不知道如何实现它们.
非常感谢.
解决方法
考虑使用
PagingTableView
class MainViewController: UIViewController {
@IBOutlet weak var contentTable: PagingTableView!
var legumes: [String] = ["Eggs","Yoga" ]
override func viewDidLoad() {
super.viewDidLoad()
contentTable.dataSource = self
contentTable.pagingDelegate = self
}
}
extension MainViewController: UITableViewDataSource {
func tableView(_ tableView: UITableView,numberOfRowsInSection section: Int) -> Int {
return legumes.count
}
func tableView(_ tableView: UITableView,cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell",for: indexPath) as! ImageTableViewCell
guard legumes.indices.contains(indexPath.row) else { return cell }
cell.content = legumes[indexPath.row]
return cell
}
}
extension MainViewController: PagingTableViewDelegate {
func paginate(_ tableView: PagingTableView,to page: Int) {
contentTable.isLoading = true
DispatchQueue.main.asyncAfter(deadline: .now() + 1) {
self.legumes.append(contentsOf: legumes)
self.contentTable.isLoading = false
}
}
}
