Here I want to display these data into two sections in my table view, I have the following arrays from the model.
Here I getting entire data into a single model and both are visible at the top.
var TotalbooksList : [BooksList]!
var RecomendBooks : [BooksList]!
var tableData: [(title: String, list: [BooksList]?)] {
return [(title: "Recomended Books", list: RecomendBooks),
(title: "Total Books", list: TotalbooksList)]
}
I write following Delegate Methods but I don't get data into a second section
func numberOfSections(in tableView: UITableView) -> Int {
return self.tableData.count
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return tableData[section].list?.count ?? 0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "RecomandBookTVCell", for: indexPath)as!RecomandBookTVCell
if let data = self.tableData[indexPath.section].list, data.count > 0 {
let model = data[indexPath.row]
cell.selectionStyle = .none
cell.booktitle.text = model.title ?? ""
cell.bookAuthor.text = model.author ?? ""
if model.photo != ""{
cell.bookimage.sd_setImage(with: URL(string: Services.BaseURL + (model.photo ?? "")), placeholderImage: UIImage(named: ""))
}
cell.genrelbl.text = model.genre ?? ""
cell.addlog.tag = indexPath.row
cell.addlog.addTarget(self, action: #selector(addLog(sender:)), for: .touchUpInside)
}
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 150
}
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 50
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
tableData[section].title
}
You are returning wrong value in numberOfRowsInSection method else condition
And you are using TotalbooksList array for section 0 in numberOfRowsInSection method and using RecomendBooks array for section 0 in cellForRow method. Change it to use proper array.
class ViewController: UIViewController {
var totalbooksList: [BooksList]!
var recomendBooks: [BooksList]!
var tableData: [(title: String, list: [BooksList]?)] {
return [(title: "Recomended Books", list: totalbooksList),
(title: "Total Books", list: recomendBooks)]
}
func numberOfSections(in tableView: UITableView) -> Int {
return self.tableData.count
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return tableData[section].list?.count ?? 0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "RecomandBookTVCell", for: indexPath) as! RecomandBookTVCell
if let data = self.tableData[indexPath.section].list, data.count > 0 {
let model = data[indexPath.row]
cell.selectionStyle = .none
cell.booktitle.text = model.title ?? ""
cell.bookAuthor.text = model.author ?? ""
if model.photo != ""{
cell.bookimage.sd_setImage(with: URL(string: Services.BaseURL + (model.photo ?? "")), placeholderImage: UIImage(named: ""))
}
cell.genrelbl.text = model.genre ?? ""
cell.addlog.tag = indexPath.row
cell.addlog.addTarget(self, action: #selector(addLog(sender:)), for: .touchUpInside)
}
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 150
}
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 44
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
tableData[section].title
}
}

Sorry this tutorial is quite poor.
Swift is an object oriented language so use a custom model, a generic Section object with name, items and the information if the section is collapsed
class Section<T> {
var name : String
var items = [T]()
var isCollapsed = false
init(name : String, items : [T] = []) {
self.name = name
self.items = items
}
}
and a suitable struct for the items with a title and a closure to be called in didSelect
struct Item {
let title : String
let selectorClosure : (() -> Void)?
}
Rather than using multiple arrays populate the data source array consistently
var sections = [Section<Item>(name:"xxxx1", items: [Item(title: "a", selectorClosure: APICalla), Item(title: "b", selectorClosure: APICallb)]),
Section<Item>(name:"xxxx2", items: [Item(title: "c", selectorClosure: APICallc)]),
Section<Item>(name:"xxxx3")]
In numberOfRowsInSection return the proper number of items depending on isCollapsed
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
let currentSection = sections[section]
return (currentSection.isCollapsed) ? 0 : currentSection.items.count
}
In cellForRow don't use typeless Foundation collection types
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifer, for: indexPath)
let item = sections[indexPath.section].items[indexPath.row]
cell.textLabel?.textColor = UIColor.black
cell.textLabel?.text = item.title
return cell
}
In the method to collapse/expand the sections just toggle isCollapsed
let currentSection = sections[section]
currentSection.isCollapsed.toggle()
and perform the animation
titleForHeaderInSection is much simpler, too
override func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return sections[section].name
}
In didSelectRow never get any data from the view (the cell) get it from the model (the data source array) and call the selector closure. With this logic a switch is not needed.
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
tableView.deselectRow(at: indexPath, animated: false)
let item = sections[indexPath.section].items[indexPath.row]
item.selectorClosure?()
}

What I'm trying to do is separate my cells into sections by their Brand
what Ive been able to do so far is pass data of selected items from HomeVC to populate the cells of the CartVC
I am trying to separate the sections by brand, the brand data is a part of the model Items Class (name, brand, imageUrl, price, & weight) and the Items class retrieves data from CloudFirestore to populate the cells of the HomeVC
How would I be able to to separate the cells into sections by their brand, when passed into the CartVC.
So far what I've done seems to fail, because once I pass an item from the HomeVC to the CartVC I only get one header cell, with the brand name of the first item I passed into the CartVC. When I pass more data into the the CartVC all the cells stay in the section of the first item passed when im trying to section off all my CartCells by their brand
extension HomeViewController: UITableViewDelegate, UITableViewDataSource {
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return itemSetup.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
guard let cell = tableView.dequeueReusableCell(withIdentifier: "HomeCell") as? HomeCell else { return UITableViewCell() }
let item = itemSetup[indexPath.row]
cell.configure(withItems: item)
cell.addActionHandler = { (option: Int) in
print("Option selected = \(option)")
self.tray.append(Tray(cart: item))
item.selectedOption = option
}
return cell
}
}
class CartViewController: UIViewController {
var items: ProductList!
var sectionModel: [SectionModel] = []
var tray: [Tray] = []
var groupedItems: [String: [Tray]] = [:]
var brandNames: [String] = []
#IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
groupedItems = Dictionary(grouping: tray, by: {$0.cart.brand})
brandNames = groupedItems.map{$0.key}.sorted()
}
}

}

return cell
}
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {

}
just set your your tableview functions like and you'll have no problem setting things up by section
func numberOfSections(in tableView: UITableView) -> Int {
return brandNames.count
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
let brand = brandNames[section]
return groupedItems[brand]!.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cartCell = tableView.dequeueReusableCell(withIdentifier: "CartCell") as! CartCell
let brand = brandNames[indexPath.section]
let itemsToDisplay = groupedItems[brand]![indexPath.row]
cartCell.configure(withItems: itemsToDisplay.cart)
return cartCell
}
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let cartHeader = tableView.dequeueReusableCell(withIdentifier: "CartHeader") as! CartHeader
let headerTitle = brandNames[section]
cartHeader.brandName.text = "Brand: \(headerTitle)"
return cartHeader
}
I have created grouped sections in UITableView but values are getting duplicate. How to populate items under each section? Sections I already created. Few Title items are null.
SectionList --> Title --> Items
Like:
Bir have one item
Proj Plan have null item
Proj Ev has three items
I want to display textField in every section Title.
code:
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
tableView.dataSource = self
tableView.delegate = self
if let url = Bundle.main.url(forResource: "AppD", withExtension: "json") {
do {
let data = try Data(contentsOf: url)
let decoder = JSONDecoder()
let jsonData = try decoder.decode(AppointmentDetail.self, from: data)
self.AppData = jsonData
self.tableView.reloadData()
} catch {
print("error:\(error)")
}
}
}
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 50
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return AppData?.sectionList?[section].title
}
func numberOfSections(in tableView: UITableView) -> Int {
return AppData?.sectionList?.count ?? 0
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return AppData?.sectionList?.count ?? 0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "tableCell", for: indexPath)
// Configure the cell...
if let sections = AppData?.sectionList?[indexPath.section].items {
for item in sections {
if item.textField != "" {
cell.textLabel?.text = item.textField
}
}
}
Make changes as below
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return AppData?.sectionList?[section].items?.count ?? 0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "tableCell", for: indexPath)
cell.textLabel?.text = AppData?.sectionList?[indexPath.section].items?[indexPath.row].textField
cell.textLabel?.sizeToFit()
cell.textLabel?.numberOfLines = 0
return cell
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableViewAutomaticDimension
}
For Adding HeaderView XIB to table view
var tableHeaderViewObj : BookNowHotelDetailHeader?
inViewdidload
tableHeaderViewObj = BookNowHotelDetailHeader(frame: CGRect(x: 0.0, y: 0.0, width: (window?.frame.width)!, height: 350))
self.BookNowTV.tableHeaderView = tableHeaderViewObj
tableHeaderViewObj?.parentVC = self
tableHeaderViewObj?.UpdateBookNowHotelData(Obj: hotelDetailObj ?? HotelDetailModal())
Here I need to pass the data to the table view to display and getting lots of errors can anyone help me how to implement this here keys should be displayed as section header title and inside values should be displayed in rows
Here is the declaration for the array
var finalDict = [String: [String]]()
the output of the array is shown below
["Flat Rate": ["Fixed", "Base", "Fixed two"], "Best Way": ["Worldwide Express Saver one", "Table Rate", "Worldwide Expedited", "Worldwide Express Saver"]]
Here is the code for table view
func numberOfSections(in tableView: UITableView) -> Int {
return finalDict.count
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
let names = self.finalDict.keys
return names[section]
}
func tableView(_ tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
let header = view as! UITableViewHeaderFooterView
header.tintColor = UIColor.white
header.textLabel?.textColor = UIColor.darkGray
header.textLabel?.textAlignment = NSTextAlignment.left
header.textLabel?.font = UIFont(name: "Futura", size: 17)
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
let names = self.finalDict.keys
let a :[Any] = finalDict[names] as! [Any]
return a.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "shippingCell", for: indexPath) as! ShippingMethodTableViewCell
let key = self.keys[indexPath.section]
progressIcon.stopAnimating()
progressIcon.hidesWhenStopped = true
var a :[Any] = arrayss[key] as! [Any]
var dictionary = a[indexPath.row] as! [String:Any]
let price = dictionary ["price"]
let name = dictionary["name"]
let namePrice = "\(name!)" + " \(price!)"
cell.methodLabel.text = namePrice
cell.radioButton.addTarget(self, action: #selector(paymentRadioAction(button:)), for: .touchUpInside)
if chekIndex == indexPath {
cell.radioButton.isSelected = true
} else {
cell.radioButton.isSelected = false
}
return cell
}
For starters, update the following datasource methods
func numberOfSections(in tableView: UITableView) -> Int {
return finalDict.count
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
let titles = Array(finalDict.keys)
return titles[section]
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
let titles = Array(finalDict.keys)
let currentTitle = titles[section]
let values = finalDict[currentTitle] as! [String]
return values.count
}
Please try to replace self.finalDict.keys with Array(self.finalDict.keys) .
I have a dictionary and importing information from my database. I need to put it specifically in the right section in my table view. All the information is provided, if you need more detail or code I will provide it.
Dictionary output ["March 27": ["do the dishes", "take out the trash"], "March 29": ["Walk the dog", "Water the plants"], "March 28": ["Clean the house"]]
var date = ["March 27", "March 28", "March 29"]
func numberOfSections(in tableView: UITableView) -> Int {
return date.count
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return date[section]
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = table.dequeueReusableCell(withIdentifier: "cell") as! Chores
//Having trouble on what to do here
return cell
}
That's how you can do, I think this is self explanatory:
var output = ["March 27": ["do the dishes", "take out the trash"], "March 29": ["Walk the dog", "Water the plants"], "March 28": ["Clean the house"]]
var date = Array(output.keys)
func numberOfSections(in tableView: UITableView) -> Int {
return date.count
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return date[section]
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return output[date[section]]?.count ?? 0
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = table.dequeueReusableCell(withIdentifier: "cell") as! Chores
var value = output[date[indexPath.section]]?[indexPath.row] ?? ""
cell.textLabel.text = value
return cell
}
// Edited in number of rows you have:
output[date[section]]?.count
it's exactly like this, this mostly gives you optionals but I will ignore it in this example:
let keyForSection = date[section]
let arrayOfStringsForKey = output[keyForSection]
let numberOfRows = arrayOfStringsForKey.count
you do similar stuff to get the actual value but instead of count you pass index of the row you want the value from
let value = arrayOfStringsForKey[rowNumber]
