How to load one cell inside another cell's view.? - ios

The above one is my inner cell. I want to load this cell inside the below cell. The number of inner cell is dynamic.
The above one is my main cell. The red colored section is a UIView. I want to add numbers of innerCell dynamically into the UIView. I tried the below code
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let mainCell = tableView.dequeueReusableCell(withIdentifier: "FlightCellMain", for: indexPath) as? FlightCellMain
let innerCell = tableView.dequeueReusableCell(withIdentifier: "FlightCell", for: indexPath) as? FlightCell
mainCell?.flightCellView.addSubview(innerCell!)
mainCell?.backgroundColor = .clear
innerCell?.backgroundColor = .clear
// innerCell?.innerCellWidthConst.constant = (mainCell?.mainView.frame.width)!
self.showStopsView(2, self.airportlist, (innerCell?.leftRound)!, (innerCell?.rightRound)!, (innerCell?.centerLine)!, (innerCell?.routeView)!)
mainCell?.flightCellViewHieghtConst.constant = (mainCell?.flightCellViewHieghtConst.constant)! + 125
innerCell?.layoutIfNeeded()
mainCell?.layoutIfNeeded()
return mainCell!
}
But the result is getting like this. I provided autolayout. When I run the two cells individually it fits its content.. Whats wrong am I doing ?
The above picture is the model that I'm trying to achieve. Where the number of flights details is dynamic.

Step 1: Create a FlightDisplayView(UIView).
import UIKit
class FlightDisplayView: UIView {
override init(frame: CGRect) {
super.init(frame: frame)
self.commonInit()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
self.commonInit()
}
private func commonInit (){
let xibs = Bundle.main.loadNibNamed("FlightDisplayView", owner: self, options: nil)
let view = xibs?.first as! UIView
view.frame = self.bounds;
self.addSubview(view)
}
}
Step 2: Create a FlightDisplayCell(UITableViewCell).
import UIKit
class FlightViewCell: UITableViewCell {
#IBOutlet weak var innerCellView:FlightDisplayView!
override func awakeFromNib() {
super.awakeFromNib()
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
Step 3: Create a mainCell(UITableViewCell).
import UIKit
class mainCell: UITableViewCell {
#IBOutlet weak var table: UITableView!
#IBOutlet var heightConstraintForFlightTableView : NSLayoutConstraint!
override func awakeFromNib() {
super.awakeFromNib()
table.delegate = self
table.dataSource = self
table.estimatedRowHeight = 100.0
table.rowHeight = UITableViewAutomaticDimension
table.register(UINib.init(nibName: "FlightViewCell", bundle: nil), forCellReuseIdentifier: "FlightViewCell")
heightConstraintForFlightTableView.constant = 0.0
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
func setInformation(_ numberOFFlight : CGFloat, _ information : NSDictionary) {
heightConstraintForFlightTableView.constant = numberOFFlight * 155.0
// 155 is fixed flight cell height
table.reloadData()
}
}
extension mainCell:UITableViewDelegate,UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 3
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "FlightViewCell")
return cell!
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return UITableViewAutomaticDimension;
}
}
Step 4: Use mainCell into your controller. (3 cell information added as a inner cell)
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "mainCell") as? mainCell
let information:NSDictionary = [:]
cell?.setInformation(3, information)
return cell!
}

Custom xib cells are not appearing on UITableView swift

my cells are not appearing.
I did:
Checked if datasource and delegate were connected
Checked if my custom cells identifier name and class were correct
Things that I didn't:
I am struggling with auto layout, so I just decided not to do it.
My app is loading with the correct amount of cells, but the cells are not registered.
My code:
import UIKit
class WelcomeViewController: UITableViewController, NetworkManagerDelegate {
private var networkManager = NetworkManager()
private var infoForCells = [Result]()
override func viewDidLoad() {
super.viewDidLoad()
self.tableView.register(UINib(nibName: "ImageViewCell", bundle: nil), forCellReuseIdentifier: "imageCell")
networkManager.delegate = self
networkManager.fetchNews()
}
// MARK: - Table view data source
override func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return infoForCells.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
guard let cell = tableView.dequeueReusableCell(withIdentifier: "imageCell", for: indexPath) as? ImageViewCell else{
return UITableViewCell(style: .default, reuseIdentifier: "cell")
}
let cellIndex = infoForCells[indexPath.row]
cell.titleForImage.text = cellIndex.alt_description
print(cell.titleForImage ?? "lol")
// if let image = cellIndex.urlToImage {
// cell.imageForArticle.load(url: image)
// }
return cell
}
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
}
func didUpdateNews(root: Root) {
infoForCells = root.results
}
}
Reload the table
func didUpdateNews(root: Root) {
infoForCells = root.results
tableView.reloadData()
}
In addition to Sh_Khan answer you can also listen to updates of infoForCells property
private var infoForCells = [Result]() {
didSet {
DispatchQueue.main.async { [weak self] in
self?.tableView.reloadData()
}
}
}

How to add UITableview within Tableview Cell using Swift

In myscenario, I am trying to add Dynamic UITableview within Static UITableview Cell. How to achieve this? I tried below code but It is not working for me.
The dynamic tableview cell count based need to readjust static tableview cell height. Please provide some sample code.
Tableview Code
import UIKit
class CustomCell: UITableViewCell,UITableViewDataSource,UITableViewDelegate {
var dataArr:[String] = []
var subMenuTable:UITableView?
override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
super.init(style: style , reuseIdentifier: reuseIdentifier)
setUpTable()
}
required init(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
setUpTable()
}
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
setUpTable()
}
func setUpTable(){
subMenuTable = UITableView(frame: CGRectZero, style:UITableViewStyle.Plain)
subMenuTable?.delegate = self
subMenuTable?.dataSource = self
self.addSubview(subMenuTable!)
}
override func layoutSubviews() {
super.layoutSubviews()
subMenuTable?.frame = CGRectMake(0.2, 0.3, self.bounds.size.width-5, self.bounds.size.height-5)
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return dataArr.count
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell: UITableViewCell? = tableView.dequeueReusableCellWithIdentifier("cellID")
if cell == nil {
cell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "cellID")
}
cell?.textLabel?.text = dataArr[indexPath.row]
return cell!
}
}
Create a single view project add tableview inside storyboard and set up its datasource and delegate
do code as below to firstViewController.swift
import UIKit
class firstViewController: UIViewController,UITableViewDataSource,UITableViewDelegate {
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 3;
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1;
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell:CustomCell? = tableView.dequeueReusableCellWithIdentifier("Cell") as? CustomCell
if cell == nil {
cell = CustomCell(style: UITableViewCellStyle.Default, reuseIdentifier: "Cell")
}
cell?.dataArr = ["subMenu->1","subMenu->2","subMenu->3","subMenu->4","subMenu->5"]
return cell!
}
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
return 150.0
}
}
create a new file CustomCell.swift which is the subclass of UITableViewCell and do not select with xib this file is without .xib file table and its cell will be created programatically.
do code as below to CustomCell.swift
import UIKit
class CustomCell: UITableViewCell,UITableViewDataSource,UITableViewDelegate {
var dataArr:[String] = []
var subMenuTable:UITableView?
override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
super.init(style: style , reuseIdentifier: reuseIdentifier)
setUpTable()
}
required init(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
setUpTable()
}
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
setUpTable()
}
func setUpTable(){
subMenuTable = UITableView(frame: CGRectZero, style:UITableViewStyle.Plain)
subMenuTable?.delegate = self
subMenuTable?.dataSource = self
self.addSubview(subMenuTable!)
}
override func layoutSubviews() {
super.layoutSubviews()
subMenuTable?.frame = CGRectMake(0.2, 0.3, self.bounds.size.width-5, self.bounds.size.height-5)
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return dataArr.count
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell: UITableViewCell? = tableView.dequeueReusableCellWithIdentifier("cellID")
if cell == nil {
cell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "cellID")
}
cell?.textLabel?.text = dataArr[indexPath.row]
return cell!
}
}
I hope it will work for you ...:)
Do this in your main controller:
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
if tableView = self.tableView {
var cell:CustomCell? = tableView.dequeueReusableCellWithIdentifier("Cell") as? CustomCell
cell.tableView.delegate = self
cell.tableView.dataSource = self
return cell!
} else {
var cell: UITableViewCell? = tableView.dequeueReusableCellWithIdentifier("cellID")//here you custom cell's tableView's cell
return cell
}
}
Basically you will have to calculate height of your child tableview as demonstrated below
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource
{
#IBOutlet weak var parentTableView : UITableView? = nil
var sections = [[String:[[String:String]]]]()
override func viewDidLoad()
{
super.viewDidLoad()
setup()
}
func setup()
{
// Data
let section1 = ["Items" : [["Title" : "Row 1"], ["Title" : "Row 2"]]]
let section2 = ["Items" : [["Title" : "Row 1"], ["Title" : "Row 2"], ["Title" : "Row 3"]]]
let section3 = ["Items" : [["Title" : "Row 1"], ["Title" : "Row 2"], ["Title" : "Row 3"], ["Title" : "Row 4"]]]
sections.append(section1)
sections.append(section2)
sections.append(section3)
// Register header
}
func numberOfSections(in tableView: UITableView) -> Int
{
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
return sections.count
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat
{
// Calculate the height of parent cell.
var cellHeight : CGFloat = 0.0
let aSection = sections[indexPath.row]
if let items = aSection["Items"]
{
cellHeight = CGFloat(44 * items.count)
}
return cellHeight
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
if let cell = tableView.dequeueReusableCell(withIdentifier: "ParentTableViewCell") as? ParentTableViewCell
{
if let aSection = sections[indexPath.row] as? [String:[[String:String]]], let items = aSection["Items"]
{
cell.configure(items: items)
}
return cell
}
return UITableViewCell()
}
}

How do I add a UITableView to a UIView?

I have 2 xib files: the custom UIView and the Custom Cell xib.
I also have a Custom Cell class that only contains a UILabel.
The names are all correct.
The delegates of the UITableView are connected to the view.
I need to add a UITableView to a UIView. From the tutorials I've read this is how to add it. But for some reason this does not work I get 2 types of errors with this code that say that I need to register the cell nib or that It finds nil when unwrapping an optional. What am I doing wrong? Please help!

return myArray.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

#IBOutlet weak var myLabel: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
}
Code For CustomView Class: Take Custom Xib For View

}
Note : Set the Xib CustomClass to UIView Class whatever you want to take in my case it is "CustomView"
Controller Code :
class CustomViewController: UIViewController {
var customView : CustomView?
override func viewDidLoad() {
super.viewDidLoad()
}
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
DispatchQueue.main.asyncAfter(deadline: DispatchTime(uptimeNanoseconds: UInt64(0.5))) {
self.loadViewCustom()
}
}
func loadViewCustom() {
self.customView = CustomView.nibInstance()
self.customView?.frame = self.view.frame
self.customView?.baseInit()
self.view.addSubview(self.customView!)
self.customView?.myTableView.reloadData()
}
}
tableView is IBOutlet in xib file? why you need addSubView?

Unable to create cell in collectionview?

I want to add a UICollectionView inside a table view cell.For this purpose, i have created below files.
CollectionCell:
class CollectionCell: UICollectionViewCell {
#IBOutlet weak var lblName: UILabel!
#IBOutlet weak var imgCell: UIImageView!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
}
I have also created a CollectionCell.xib
CollectionView.swift
class CollectionView: UIView {
#IBOutlet weak var collectionview: UICollectionView!
var arrItems:[String] = []
/*
// Only override draw() if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
override func draw(_ rect: CGRect) {
// Drawing code
}
*/
func configureCollectionView()
{
collectionview.register(CollectionCell.self, forCellWithReuseIdentifier: "CollectionCell")
collectionview.delegate = self
collectionview.dataSource = self
}
func setCollectionViewDatasource(arrItems:[String])
{
self.arrItems = arrItems
self.collectionview.reloadData()
}
static func initiateView()->CollectionView
{
let nib = UINib(nibName: "CollectionView", bundle: nil)
let view = nib.instantiate(withOwner: nil, options: nil)[0] as! CollectionView
return view
}
}
extension CollectionView:UICollectionViewDelegate
{
}
extension CollectionView:UICollectionViewDataSource
{
func numberOfSections(in collectionView: UICollectionView) -> Int {
return 1
}
func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
return arrItems.count
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell:CollectionCell = collectionView.dequeueReusableCell(withReuseIdentifier: "CollectionCell", for: indexPath) as! CollectionCell
cell.lblName.text = arrItems[indexPath.row]
return cell
}
}
I have also created CollectionView.xib
Now as i want to add a collectionview inside a tableview cell for that purpose i have created a cutom tableview cell class as CustomTableCell
class CustomTableCell: UITableViewCell {
var view = CollectionView()
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
print("ceonstatructir init")
// insitate a nib
view = CollectionView.initiateView()
view.configureCollectionView()
contentView.addSubview(view)
view.setCollectionViewDatasource(arrItems: ["firest","second","thierd"])
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
func setDataSource(arrItems:[String])
{
//view.setCollectionViewDatasource(arrItems: arrItems)
}
}
Now i have created a mainViewController to show the data on tableview so i have crteated viewcontroller.swift
class ViewController: UIViewController,UITableViewDelegate,UITableViewDataSource {
#IBOutlet weak var tableview: UITableView!
let sectionArray = ["First","Second","Third","Fourth","Fifth"]
let collectionArray = [["First","Second","Third"],["First","Second","Third"],["First","Second","Third"],["First","Second","Third"],["First","Second","Third"]]
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
tableview.register(CustomTableCell.self, forCellReuseIdentifier: "TableCell")
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfSections(in tableView: UITableView) -> Int {
return sectionArray.count
}
func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return sectionArray[section]
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell:CustomTableCell = tableView.dequeueReusableCell(withIdentifier: "TableCell", for: indexPath) as! CustomTableCell
return cell
}
func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
let cell:CustomTableCell = cell as! CustomTableCell
let dataSource = collectionArray[indexPath.section]
cell.setDataSource(arrItems:dataSource)
}
}
Now i am trying to send datasource to my collectionview when tableviewcell is just created.But i am getting crash in cellForItemAtIndexPath in collectionview.I am getting cell as nil in cellForItemAyIndexPath.Please tell me what is the issue with it.
In Collectionview.swift change this function
func configureCollectionView()
{
let nib = UINib(nibName: "CollectionCell", bundle: nil)
collectionview.register(nib, forCellWithReuseIdentifier: "cell")
collectionview.delegate = self
collectionview.dataSource = self
}
In cellforItemat change this line
let cell:CollectionCell = collectionView.dequeueReusableCell(withReuseIdentifier: "CollectionCell", for: indexPath) as! CollectionCell
to
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cell", for: indexPath) as! CollectionCell

Swift / How to populate UITableViewCells

I have a controller with a Table View on it. Have defined my cells in a view and then I bind it to the table view. (Please excuse the terminology). App builds and runs fine but none of the labels defined in the cell show anything. Entire table is blank except for the cell separators. I've followed numerous tutorials and searched SO extensively for reasons, how to create (Create a Table View - Apple docs), settings to check, all with the same results. I've also tried cleaning, restarting Xcode, etc. This is Xcode 8/Swift 3.
The view controller has a table view and I register the cell class like so in the viewDidLoad
self.tableView.registerCellClass(MenuTableViewCell.self)
UITableViewDataSource code
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return menusItems.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: MenuTableViewCell.identifier, for: indexPath) as! MenuTableViewCell
let item = menusItems[indexPath.row]
cell.setData(item)
return cell
}
menuItems is an array of a struct I have that is created before anything else is done
BaseTableViewCell
open class BaseTableViewCell: UITableViewCell {
class var identifier: String { return String.className(self) }
public required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
setup()
}
override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
setup()
}
open override func awakeFromNib() {
}
open func setup() {
}
open override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
open class func height() -> CGFloat {
return 48
}
open func setData(_ data: Any?) {
if let menuText = data as? String {
self.textLabel?.text = menuText
}
if let menuImage = data as? UIImage {
self.imageView?.image = menuImage
}
}
}
Table View Cell code - inherits the BaseTableViewCell
class MenuTableViewCell: BaseTableViewCell {
//MARK: Properties
#IBOutlet weak var name: UILabel!
#IBOutlet weak var icon: UIImageView!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
override func setData(_ data: Any?) {
if let data = data as? MenuTableViewCellData {
NSLog("menu name - %#", data.text)
self.icon?.image = data.image
self.name?.text = data.text
}
}
}
All menu names are written to the debug area so the code is being executed.
I don't know if there is hook that is missing or if something else. Please let me know if anything further is also needed. Any help is appreciated.
Screenshots showing IBOutlets connected
Here is the delegate and data source from the controller
extension LeftViewController : UITableViewDelegate {
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return MenuTableViewCell.height()
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if let menu = LeftMenu(rawValue: indexPath.row) {
self.changeViewController(menu)
}
}
func scrollViewDidScroll(_ scrollView: UIScrollView) {
if self.tableView == scrollView {
}
}
}
extension LeftViewController : UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return menusItems.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: MenuTableViewCell.identifier, for: indexPath) as! MenuTableViewCell
let item = menusItems[indexPath.row]
cell.setData(item)
return cell
}
}
Thanks everyone for your help. I was able to get it working. I removed the XIB file, created the layout in the view and then wired it up from there (followed here for how to).
Verify that you've connected the IBOutlets for name and icon in MenuTableViewCell. Assuming what you say is true, that the NSLog in setData is called, chances are you haven't connected the IBOutlets for the table view cell subclass.
You may have 0-height rows. I see a height method in there - what is calling it? Do you have an implementation of
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat
somewhere?
Are you setting the table view's rowHeight?
Can you check whether name and icon have proper constraints
