【问题描述】：
具有三个复选框[in,out,absent] 的表格视图如果单击任何一个复选框[in,out,absent] 则调用 Json 服务 并在 tableview 中显示数据，除了 [Out] 复选框外，所有工作正常。如果我在 [outlabel:11:54 PM] 必须显示的标签处单击 [out] 复选框结果。它显示为空 在 [outlabelg: ] 处，如果我单击 tableview 中的下一个单元格 [out checkbox] 会更新私有 [out:Labledata] 数据并显示所选单元格 [out:lable]data 。请帮助我在哪里做错了
这是表格视图代码
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
}
这是out复选框的代码[in,absent也和这种方式的代码一样]
@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)
}
【问题讨论】：
-
不相关，但
if(attendanceInfo.count>0){完全没用。如果数组为空，numberOfRows返回 0 并且根本不调用cellForRow。 -
Json 数据存入到出勤信息中，不知道怎么统计学生数
-
我的意思是这个检查是没有意义的，它永远不会评估为假。
-
我可以删除它，但让出席=出席信息[行]作为出席信息
-
我在行位置出现此错误致命错误：索引超出范围
