在里面
TableView
自定义单元格(如果要添加)
views
从…起
storyboard
或
XIB
然后它会在滚动时被删除,但如果您正在添加
意见
然后,您必须以编程方式从
tableViewCell
:
在中使用以下代码
cellForRow
:
for label in cell.subviews {
if let mylabel = label as? UILabel {
mylabel.removeFromSuperview()
}
}
或者您可以使用此代码
customCellClass
在里面
prepareForReuse
方法:
class myCustomCell: UITableViewCell {
override func prepareForReuse() {
super.prepareForReuse()
for view in self.subviews {
view.removeFromSuperview()
}
}
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
}
上述代码将从单元格中删除所有子视图。

我用字符串尝试了下面的代码
Array
和
swipeDelete
功能性
tableView
:
class ViewController: UIViewController {
@IBOutlet weak var sampleTableView: UITableView!
var nameArray = ["Snoop", "Sarah", "Fido", "Mark", "Jill", "Parague", "London", "Barcelona", "Italy", "France", "Eiffiel", "Tower", "Paris", "Europe", "Amsterdam", "Zurich", "Germany", "Munich", "Milan", "Venice", "Switzerland", "Brussels"]
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
}
extension ViewController: UITableViewDataSource, UITableViewDelegate {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return nameArray.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cellIdentifier", for: indexPath)
cell.textLabel?.text = nameArray[indexPath.row] + " - " + String(describing: indexPath.row)
return cell
}
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
if (editingStyle == UITableViewCellEditingStyle.delete) {
// handle delete (by removing the data from your array and updating the tableview)
tableView.beginUpdates()
nameArray.remove(at: indexPath.row)
tableView.deleteRows(at: [indexPath], with: .automatic)
tableView.endUpdates()
}
}
}
当我开始滑动时,删除
桌面视图
细胞
string
数据是正确的,但是
indexPath
价值不会改变。当我滚动页面时,它会改变
桌面视图
。这在逻辑上是正确的,因为删除后字符串数据索引已更改,并且当重新使用单元格时,新索引将可见。
使用SwipCellKit编辑:
将与您相同的代码用于
SwipeCellKit
:
我的
ViewController
:
class ViewController: UIViewController {
@IBOutlet weak var sampleTableView: UITableView!
var nameArray = ["Snoop", "Sarah", "Fido", "Mark", "Jill", "Parague", "London", "Barcelona", "Italy", "France", "Eiffiel", "Tower", "Paris", "Europe", "Amsterdam", "Zurich", "Germany", "Munich", "Milan", "Venice", "Switzerland", "Brussels"]
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
}
extension ViewController : UITableViewDataSource, UITableViewDelegate, SwipeTableViewCellDelegate {
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 72
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return nameArray.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "reuseIdentifier") as! CustomTableCell
cell.delegate = self
cell.atest.text = nameArray[indexPath.row] + " - " + String(describing: indexPath.row)
cell.btest.text = "another different text from an array";
return cell;
}
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath, for orientation: SwipeActionsOrientation) -> [SwipeAction]?
{
let delete = SwipeAction(style: .destructive, title: "Delete")
{
action, indexPath in
print("delete button tapped")
self.nameArray.remove(at: indexPath.row)
self.sampleTableView.deleteRows(at: [indexPath], with: .none)
}
delete.backgroundColor = UIColor.red;
return [delete];
}
}
我的
CustomTableViewCell
:
class CustomTableCell: SwipeTableViewCell {
public var atest = UILabel()
public var btest = UILabel()
var animator: Any?
override func awakeFromNib() {
atest = UILabel(frame: CGRect(x: 20 , y: 2, width: 200, height: 30));
btest = UILabel(frame: CGRect(x: 20 , y: 32, width: 200, height: 30));
self.contentView.addSubview(atest);
self.contentView.addSubview(btest);
}
}
其工作原理与第一次编辑相同。
编辑
CustomTableViewCell
使用
init
:
class CustomTableViewCell: SwipeTableViewCell {
public var atest = UILabel();
public var btest = UILabel();
var animator: Any?
override init(style: UITableViewCellStyle, reuseIdentifier: String!)
{
super.init(style: style, reuseIdentifier: reuseIdentifier)
atest = UILabel(frame: CGRect(x: 20 , y: 2, width: 100, height: 30))
btest = UILabel(frame: CGRect(x: 20 , y: 32, width: 100, height: 30))
self.contentView.addSubview(atest)
self.contentView.addSubview(btest)
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
fatalError("init(coder:) has not been implemented")
}
}
变化
cellForRow
:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = CustomTableViewCell.init(style: .default, reuseIdentifier: "reuseIdentifier")
cell.delegate = self
cell.atest.text = nameArray[indexPath.row] + " - " + String(describing: indexPath.row)
cell.btest.text = "another different text from an array";
return cell;
}
仍然和上面一样工作。
