How to list the data in the tableview - ios

Question

This is the screen shot. According to this how to list the data in the tableview:
Already I have code as below.
func numberOfSections(in tableView: UITableView) -> Int {
return questionViewModel.numberOfSections()
}
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 100
} func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let identifier = "HeaderCell"
var headercell: questionheader! = tableView.dequeueReusableCell(withIdentifier: identifier) as? questionheader
if headercell == nil {
tableView.register(UINib(nibName: "questionheader", bundle: nil), forCellReuseIdentifier: identifier)
headercell = tableView.dequeueReusableCell(withIdentifier: identifier) as? NH_questionheader
} headercell.setReviewData(reviews:questionViewModel.titleForHeaderInSection(atsection:section))
headercell.isUserInteractionEnabled = false
return headercell
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return questionViewModel.numberOfRowsIn(section: section)
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
let model = questionViewModel.titleForHeaderInSection(atsection: indexPath.section)
print(model.answerType)
print(model.answerType?.rawValue)
let c = model.answerType
return c!.cellType().getHeight()
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let model = questionViewModel.titleForHeaderInSection(atsection: indexPath.section)
print(model.answerType)
print(model.answerType?.rawValue)
let c = model.answerType
let cellClass = c?.cellType().getClass()
print(cellClass)
let cell = tableView.dequeueReusableCell(withIdentifier: (cellClass?.cellReuseIdentifier())!, for: indexPath) as! BaseCell
print(cell)
cell.selectionStyle = .none
let optionModel = questionViewModel.datafordisplay(atindex: indexPath)
cell.setOptions(Options1: optionModel)
cell.delegate = self
if optionModel.isSelected!
{
print(optionModel.isSelected)
cell.setOptions1(OptionsSelected:optionModel)
}
else {
print(optionModel.isSelected)
cell.setOptions1(OptionsisSelected:optionModel)
}
cell.type = c?.cellType()
print(cell.type)
else if cell.type == .radiotype{
cell.selectionStyle = .none
}
return cell
}
This is my code. But according to this I will get the output as below screen shot.
Actually initially I need to display the section header as: - Please tell about us
After that there is subsection. The subsection questions header are as below: -1. knowledge 2. friendly or not
Then in the subsections display the options. How to do implement?

Answer 1

You can just display "Please tell us about" as UILabel above the table.

Answer 2

Below example may help you out.
let sections = [ // All sections
[ // Sports section
["Baseball", "Softball", "Cricket"], // Bat-and-Ball sub-section
["Field Hockey", "Ice Hockey", "Roller Hockey"] // Hockey subsection
], [ // Engineering section
["Software Engineer", "Electrical Engineer"] // Computer Science subsection
]
]
func numberOfSections(in tableView: UITableView) -> Int {
return sections.count
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
let sectionItems = sections[section]
var numberOfRows: Int = sectionItems.count // For second level section headers
for rowItems: [Any] in sectionItems as? [[Any]] ?? [] {
numberOfRows += rowItems.count // For actual table rows
}
return numberOfRows
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
var sectionItems = sections[indexPath.section]
var sectionHeaders = self.sectionHeaders[indexPath.section]
let itemAndSubsectionIndex: IndexPath? = computeItemAndSubsectionIndex(for: indexPath)
let subsectionIndex = Int(itemAndSubsectionIndex?.section ?? 0)
let itemIndex: Int? = itemAndSubsectionIndex?.row
if (itemIndex ?? 0) < 0 {
// Section header
let cell: UITableViewCell = tableView.dequeueReusableCell(withIdentifier: "SECTION_HEADER_CELL", for: indexPath)
cell.textLabel?.text = sectionHeaders[subsectionIndex] as? String
return cell
}
else{
let cell: UITableViewCell = tableView.dequeueReusableCell(withIdentifier: "ROW_CONTENT_CELL", for: indexPath)
cell.textLabel?.text = sectionItems[subsectionIndex][itemIndex ?? 0] as? String
return cell
}
}
func computeItemAndSubsectionIndex(for indexPath: IndexPath?) -> IndexPath? {
var sectionItems = sections[Int(indexPath?.section ?? 0)]
var itemIndex: Int? = indexPath?.row
var subsectionIndex: Int = 0
for i in 0..<sectionItems.count {
// First row for each section item is header
itemIndex = (itemIndex ?? 0) - 1
// Check if the item index is within this subsection's items
let subsectionItems = sectionItems[i] as? [Any]
if (itemIndex ?? 0) < Int(subsectionItems?.count ?? 0) {
subsectionIndex = i
break
} else {
itemIndex = itemIndex! - (subsectionItems?.count)!
}
}
return IndexPath(row: itemIndex ?? 0, section: subsectionIndex)
}
