泰伯維三個複選框[IN，OUT，無]如果單擊任意一個複選框[IN，OUT，缺席]這是調用JSON的服務 並顯示數據除[Out]複選框外，所有桌面視圖都可以正常工作。如果[Out]複選框的結果在[outlabel：11：54 PM]之類的標籤上必須顯示。它在[outlabelg：]處顯示爲空 ，如果我在tableview中單擊下一個單元格[out checkbox]，更新了privieous [out：Labledata]數據並顯示選定單元格[out：lable]數據。請幫我在哪裏，我沒有錯
這是實現代碼如下代碼
func numberOfSections(in tableView: UITableView) -> Int {
return (attendanceInfo.count == 0) ? 0 : 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return attendanceInfo.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell =
tableView.dequeueReusableCell(
withIdentifier: "DetailsCell", for: indexPath) as! AttendanceDetailsTableViewCell
let row = (indexPath as NSIndexPath).row
cell.InButton.tag = row
cell.OutButton.tag = row
cell.AbsentButton.tag = row
let maskLayer = CAShapeLayer()
let bounds = cell.bounds
maskLayer.path = UIBezierPath(roundedRect: CGRect(x: 5, y: 3, width: bounds.width-15, height: bounds.height-15), cornerRadius: 2).cgPath
cell.layer.mask = maskLayer
if(attendanceInfo.count>0){
let attendance = attendanceInfo[row] as AttendanceInfo
cell.AttendnceLabel.textColor = UIColor(red: CGFloat(0x00)/255
,green: CGFloat(0xB1)/255
,blue: CGFloat(0xB1)/255
,alpha: 1.0)
cell.AbsentInfoLabel.isHidden = true
cell.Absentinfovalue.isHidden = true
if(attendance.inTime == "")&&(attendance.outTime == "")
{
cell.InButton.isHidden = false
cell.OutButton.isHidden = true
cell.AbsentButton.isHidden = true
cell.OutinfoLabel.isHidden = false
}
if(attendance.inTime != "")
{
cell.InButton.isHidden = true
cell.OutButton.isHidden = false
cell.AbsentButton.isHidden = false
cell.OutinfoLabel.isHidden = false
}
if(attendance.inTime != "") && (attendance.outTime != "")
{
cell.InButton.isHidden = true
cell.OutButton.isHidden = true
cell.AbsentButton.isHidden = true
cell.OutinfoLabel.isHidden = false
cell.OutLable.text = attendance.outTime
}
if(attendance.attendance == "PRESENT")
{
cell.OutLable.text = attendance.outTime
}
if(attendance.attendance == "ABSENT")
{
cell.InButton.isHidden = true
cell.OutButton.isHidden = true
cell.AbsentButton.isHidden = true
cell.Absentinfovalue.isHidden = false
cell.OutLable.isHidden = true
cell.OutinfoLabel.isHidden = true
cell.AttendnceLabel.textColor = UIColor.red
cell.Absentinfovalue.text = attendance.updatedTime
}
cell.Class.text = attendance.standard
cell.NameLabel.text = attendance.name
cell.InLabel.text = attendance.inTime
cell.OutLable.text = attendance.outTime
cell.AttendnceLabel.text = attendance.attendance
cell.DateLablel.text = attendance.attendanceDate
cell.attendanceid = attendance.attendanceId
cell.backgroundView = UIImageView(image: UIImage(named: "background_common")!)
cell.Profileimage.image = UIImage(named: "profile_pic")
cell.Profileimage.downloadImageFrom(link: attendance.photo!, contentMode: UIViewContentMode.scaleAspectFit)
if(InCheckec[indexPath.row]==true)
{
cell.InButton.setBackgroundImage(UIImage(named: "Check_Box"), for: UIControlState.normal)
cell.InButton.isSelected = true
}
else{
cell.InButton.setBackgroundImage(UIImage(named: "uncheck_Box"), for: UIControlState.normal)
cell.InButton.isSelected = false
}
if(OutCheckec[indexPath.row]==true)
{
cell.OutButton.setBackgroundImage(UIImage(named: "Check_Box"), for: UIControlState.normal)
cell.OutButton.isSelected = true
}
else{
cell.OutButton.setBackgroundImage(UIImage(named: "uncheck_Box"), for: UIControlState.normal)
cell.OutButton.isSelected = false
}
if(AbsentCheckec[indexPath.row]==true)
{
cell.AbsentButton.setBackgroundImage(UIImage(named: "Check_Box"), for: UIControlState.normal)
cell.AbsentButton.isSelected = true
}
else{
cell.AbsentButton.setBackgroundImage(UIImage(named: "uncheck_Box"), for: UIControlState.normal)
cell.AbsentButton.isSelected = false
}
}
return cell
}
這是出於複選框的代碼[中，不存在也同樣喜歡的代碼，這種方式]
@IBAction func OUTBUTTON(_ sender: UIButton) {
snackbar.backgroundColor = UIColor(red: CGFloat(0x00)/255
,green: CGFloat(0xB1)/255
,blue: CGFloat(0xB1)/255
,alpha: 1.0)
status = "2"
let buttontag = sender.tag
let prefs:UserDefaults = UserDefaults.standard
StaffID = prefs.value(forKey: "STAFFID") as! String
let position: CGPoint = sender.convert(CGPoint(x: 10, y: 20), to: self.TableView)
let indexPath = self.TableView.indexPathForRow(at: position)
if (sender.isSelected == true)
{
OutCheckec[buttontag] = false
inButtoncount -= 1
if(inButtoncount == 0)
{
snackbar.dismiss()
upStudentId.removeAll()
upAttendanceID.removeAll()
UPstatusTest.removeAll()
}
else{
upStudentId.removeLast()
UPstatusTest.removeLast()
upAttendanceID.removeLast()
}
}
else
{
OutCheckec[buttontag] = true
AbsentCheckec[buttontag] = false
inButtoncount += 1
snackbar.show()
let out:Bool = true
prefs.set(out, forKey:"1")
let kid = attendanceInfo[(indexPath?.row)!] as AttendanceInfo
upStudentId.append(kid.studentId!)
upAttendanceID.append(kid.attendanceId)
UPstatusTest.append(status)
upStaffId = StaffID
}
self.TableView.reloadRows(at: [indexPath!], with: UITableViewRowAnimation.none)
}
這是的Json結果 
不相關，但'if（attendanceInfo.count> 0）{'完全沒用。如果數組爲空，那麼'numberOfRows'返回0，'cellForRow'根本不被調用。 – vadian
