我想在点击save按钮后从tableview获取数据。但是当用户第二次更改值时，相同的值两次追加。[
[在此处输入图像说明][1]
][2]
协议按钮选择{func tapStar（IndexPath：IndexPath,star：Int）}
类LeavedayDetailScell：UITableViewCell{
@IBOutlet weak var leaveDateLabel: UILabel!
@IBOutlet weak var leaveDateName: UILabel!
@IBOutlet weak var firstButton: UIButton!
@IBOutlet weak var seconButton: UIButton!
@IBOutlet weak var fullButton: UIButton!
var delegate:ButtonSelect?
var indexpath:IndexPath?
@IBAction func bittonPressed(_ sender: UIButton) {
delegate?.tapStar(indexPath: indexpath!, star: sender.tag)
}
}
类DayDetailsController：UIViewController
@IBAction func ButtonPressed(_sender:UIButton){
// i want to submit tableview result with radio button value change this place
//示例如
//[“03/27/2021+1”,“03/28/2021+2”]
//我的结果
//[“03/27/2021+1”,“03/28/2021+2”,“03/27/2021+3”,“03/28/2021+2”]//相同值两次
}
}
扩展DayDetailsController：UITableViewDelegate,UITableViewDataSource{func tableView(_tableView:UITableView,numberOfRowsInSection section：Int）->Int{
return listDayDetailsData.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier:"LeaveDayDetailsCell",for: indexPath) as! LeaveDayDetailsCell
cell.leaveDateLabel.text = listDayDetailsData[indexPath.row]["BreakDate"] as? String ?? "-"
cell.leaveDateName.text = listDayDetailsData[indexPath.row]["DateName"] as? String ?? "-"
cell.layer.borderColor = #colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
cell.layer.borderWidth = 2
dayDetailsTableView.rowHeight = 132.00
cell.delegate = self
cell.indexpath = indexPath
return cell
}
}
扩展DayDetailsController：按钮选择{
func tapStar(indexPath: IndexPath, star: Int) {
let cell = dayDetailsTableView.cellForRow(at: indexPath) as! LeaveDayDetailsCell
if star == 1{
cell.firstButton.setImage(UIImage(named: "radioFull.png"), for: .normal)
cell.seconButton.setImage(UIImage(named: "radioBlank.png"), for: .normal)
cell.fullButton.setImage(UIImage(named: "radioBlank.png"), for: .normal)
totalvalue = star
}
else if star == 2{
cell.firstButton.setImage(UIImage(named: "radioBlank.png"), for: .normal)
cell.seconButton.setImage(UIImage(named: "radioFull.png"), for: .normal)
cell.fullButton.setImage(UIImage(named: "radioBlank.png"), for: .normal)
totalvalue = star
}
else if star == 3{
cell.firstButton.setImage(UIImage(named: "radioBlank.png"), for: .normal)
cell.seconButton.setImage(UIImage(named: "radioBlank.png"), for: .normal)
cell.fullButton.setImage(UIImage(named: "radioFull.png"), for: .normal)
totalvalue = star
}
answerValue.append("\(listDayDetailsData[indexPath.row]["BreakDate"] as! String) + \(totalvalue)")
print(answerValue,"****answer")
}
}
在listDayDetailsData中保留星计数，并根据按钮点击更新值
离开
class LeaveDayDetailsCell: UITableViewCell {
@IBOutlet weak var leaveDateLabel: UILabel!
@IBOutlet weak var leaveDateName: UILabel!
@IBOutlet weak var firstButton: UIButton!
@IBOutlet weak var seconButton: UIButton!
@IBOutlet weak var fullButton: UIButton!
}
DayDetailsController扩展
extension DayDetailsController:UITableViewDelegate,UITableViewDataSource{
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return listDayDetailsData.count
}
@objc func firstButtonPressed(sender: UIButton) {
let index = sender.tag
// Update star value in listDayDetailsData[index]
// Reload single row at index 0
dayDetailsTableView.reloadRows(at: [IndexPath(row: index, section: 0)], with: .none)
}
@objc func secondButtonPressed(sender: UIButton) {
let index = sender.tag
// Update star value in listDayDetailsData[index]
// Reload single row at index 0
dayDetailsTableView.reloadRows(at: [IndexPath(row: index, section: 0)], with: .none)
}
@objc func fullButtonPressed(sender: UIButton) {
let index = sender.tag
// Update star value in listDayDetailsData[index]
// Reload single row at index 0
dayDetailsTableView.reloadRows(at: [IndexPath(row: index, section: 0)], with: .none)
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier:"LeaveDayDetailsCell",for: indexPath) as! LeaveDayDetailsCell
// cell.leaveDateLabel.text = listDayDetailsData[indexPath.row]["BreakDate"] as? String ?? "-"
// cell.leaveDateName.text = listDayDetailsData[indexPath.row]["DateName"] as? String ?? "-"
cell.layer.borderColor = #colorLiteral(red: 1, green: 1, blue: 1, alpha: 1)
cell.layer.borderWidth = 2
cell.firstButton.tag = indexPath.row
cell.seconButton.tag = indexPath.row
cell.fullButton.tag = indexPath.row
cell.firstButton.addTarget(self, action: #selector(firstButtonPressed(sender:)), for: .touchUpInside)
cell.firstButton.addTarget(self, action: #selector(secondButtonPressed(sender:)), for: .touchUpInside)
cell.firstButton.addTarget(self, action: #selector(fullButtonPressed(sender:)), for: .touchUpInside)
switch listDayDetailsData[indexPath.row]["Star"] as! Int {
case 1:
// Update your cell buttons
break
case 2:
// Update your cell buttons
break
case 3:
// Update your cell buttons
break
default:
// Default case
break
}
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 132.00
}
}
专业提示：
使用对象来保存数据比使用字典更好
例如
struct DayDetails {
var breakDate: String
var dateName: String
var stars: Int
//....
}
还有第三方库可用于处理星级UI以及https://github.com/evgenyneu/cosmos
