我有TableView
,用户可以点击并展开每个单元格(UI:click)。这是代码(我也创建了.xib
文件来布局这个单元格):
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, UISearchResultsUpdating {
var selectedIndex: IndexPath?
var isExpended = false
func didExpandCell() {
self.isExpended = !isExpended
self.tableView.reloadRows(at: [selectedIndex!], with: .automatic)
}
@IBOutlet weak var tableView: UITableView!
...
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "wordCell", for: indexPath) as! CellController
if searchController.isActive {
cell.word.text = filtered[indexPath.row].word
cell.translation.text = filtered[indexPath.row].translation
cell.date.text = filtered[indexPath.row].fullDate
cell.exOne.text = filtered[indexPath.row].exOne
cell.exTwo.text = filtered[indexPath.row].exTwo
} else {
cell.word.text = words[indexPath.row].word
cell.translation.text = words[indexPath.row].translation
cell.date.text = words[indexPath.row].fullDate
cell.exOne.text = words[indexPath.row].exOne
cell.exTwo.text = words[indexPath.row].exTwo
}
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
self.selectedIndex = indexPath
self.didExpandCell()
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
if isExpended && self.selectedIndex == indexPath {
return 180
}
return 70
}
}
此外,所有单元格都可以滑动。这是代码:
func tableView(_ tableView: UITableView, editActionsForRowAt: IndexPath) -> [UITableViewRowAction]? {
let edit = UITableViewRowAction(style: .normal, title: "Edit") { action, index in
print("Edit")
}
edit.backgroundColor = .blue
let delete = UITableViewRowAction(style: .normal, title: "Delete") { action, index in
print("Delete")
}
delete.backgroundColor = .red
return [delete, edit]
}
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
问题:
当我滑动Cell时,它总是花费一半,这是我刷完后的UI:click。如果我刷它们,是否有可能不扩展Cell?
答案 0 :(得分:0)
不好意思,但问题是我没有为扩展版本的单元格设置约束。这就是为什么这些标签随着滑动菜单移动的原因。现在它有效。 感谢您的所有回复!
