我的TableView有问题。添加部分页脚后,我意识到当我滑动到删除时它会移动。
我创建了一个只有这个功能的小项目来展示我面临的问题。 这是我得到的结果
我有两个TableViewCell:DetailCell
import UIKit
class DetailCell: UITableViewCell {
@IBOutlet weak var myTextLabel: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
}
和HeaderFooterCell
import UIKit
class HeaderFooterCell: UITableViewCell {
@IBOutlet weak var thisTextLabel: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
}
这是tableViewController
import UIKit
class TableViewController: UITableViewController {
override func viewDidLoad() {
super.viewDidLoad()
let statusBarHeight = UIApplication.shared.statusBarFrame.height
self.tableView.contentInset = UIEdgeInsetsMake(statusBarHeight, 0.0, 0.0, 0.0)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
// MARK: - Table view data source
override func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 5
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "myTableViewCell", for: indexPath) as! DetailCell
switch indexPath.row {
case 0: cell.myTextLabel?.text = "one - one - one - one"
case 1: cell.myTextLabel?.text = "two - two - two - two"
case 2: cell.myTextLabel?.text = "three - three - three - three"
case 3: cell.myTextLabel?.text = "four - four - four - four"
case 4: cell.myTextLabel?.text = "five - five - five - five"
default: break
}
return cell
}
override func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 44
}
override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let cell = tableView.dequeueReusableCell(withIdentifier: "headerOrFooterCell") as! HeaderFooterCell
cell.thisTextLabel.text = "Less"
return cell
}
override func tableView(_ tableView: UITableView, heightForFooterInSection section: Int) -> CGFloat {
return 44
}
override func tableView(_ tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {
let cell = tableView.dequeueReusableCell(withIdentifier: "headerOrFooterCell") as! HeaderFooterCell
cell.thisTextLabel.text = "More"
return cell
}
// MARK: RowAction for DELETE and MODIFY
override func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
let delete = UITableViewRowAction(style: .destructive, title: "Delete") { (action, indexPath) in
print ("Delete")
}
let modify = UITableViewRowAction(style: .normal, title: "Modify") { (action, indexPath) in
print("Modify")
}
return [delete, modify]
}
}
我是否犯了错误,或者是否有办法横向阻止页眉和页脚?
答案 0 :(得分:4)
将页眉和页脚的类型更改为UITableViewHeaderFooterView,然后使用.dequeueReusableHeaderFooterView(withIdentifier:“headerOrFooterCell”)tableView方法。不要忘记注册笔尖。我测试了下面的代码,它的工作没有问题,你正在撰写。
import UIKit
class DetailCell: UITableViewCell {
@IBOutlet weak var myTextLabel: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
}
}
class HeaderFooterCell: UITableViewHeaderFooterView {
@IBOutlet weak var thisTextLabel: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
}
}
class TableViewController: UITableViewController {
override func viewDidLoad() {
super.viewDidLoad()
let statusBarHeight = UIApplication.shared.statusBarFrame.height
self.tableView.contentInset = UIEdgeInsetsMake(statusBarHeight, 0.0, 0.0, 0.0)
self.tableView.register(UINib(nibName:"DetailCell", bundle: nil), forCellReuseIdentifier: "myTableViewCell")
self.tableView.register(UINib(nibName:"HeaderFooterCell", bundle: nil), forHeaderFooterViewReuseIdentifier: "headerOrFooterCell")
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
// MARK: - Table view data source
override func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 5
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "myTableViewCell", for: indexPath) as! DetailCell
switch indexPath.row {
case 0: cell.myTextLabel?.text = "one - one - one - one"
case 1: cell.myTextLabel?.text = "two - two - two - two"
case 2: cell.myTextLabel?.text = "three - three - three - three"
case 3: cell.myTextLabel?.text = "four - four - four - four"
case 4: cell.myTextLabel?.text = "five - five - five - five"
default: break
}
return cell
}
override func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 44
}
override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let cell = tableView.dequeueReusableHeaderFooterView(withIdentifier: "headerOrFooterCell") as! HeaderFooterCell
cell.thisTextLabel.text = "Less"
return cell
}

}
override func tableView(_ tableView: UITableView, viewForFooterInSection section: Int) -> UIView? {
let cell = tableView.dequeueReusableHeaderFooterView(withIdentifier: "headerOrFooterCell") as! HeaderFooterCell
cell.thisTextLabel.text = "More"
return cell
}
// MARK: RowAction for DELETE and MODIFY
