On my main.Storyboard I have a TableViewController which is set to a custom class with TableViewController.swift.
The swift file has all the tableview functions defined and the #IBOutlet for the UITableView connected. The classes defined are UINavigationController,UITableViewDelegate. This viewController is called from a secondViewController via the prepareForSegue function.
I also created CustomCell.swift with class UITableViewCell and all #IBOutlet for the labels in my UITableViewCell which has been set to the customCell class.
I can't paste all my code but if you need to look at any specific code let me know and I will be happy to post that.
The Build succeeds and the app runs but the tableviewcells don't show up and none of the tableview functions are called. I see 2 flash animated screens - indicating that the tableviewcell might have 2 views - but can't figure out where I should be checking?

have you configured ResultsCell in story board or in view didload. check it once. if not try to add the following code into your view didload
[self.tableView registerNib:[UINib nibWithNibName:#"ResultsCell" bundle:[NSBundle mainBundle]] forCellReuseIdentifier:#"ResultsCell"];
I have spent fair bit of my time trying to get this issue resolved and decided to go without the tableviewcell, instead I have created custom viewControllers and defined labels to display the results from the DB search (which is working OK) and used the perform segue function to pass values between viewcontrollers. So now my app works the way I want - maybe not ideal from a programming side but due to time constraints I had to get this working.
I have my app as a Tabbed Application with First and Second ViewControllers. The FirstViewController adds data to the SQLLite DB and the Second searches for the data and displays the results. for displaying the results I created a Custom viewController with labels for the data that I wanted displayed and passed all data from the DB results in SecondViewController functions to it and updated the labels with the data. As long as I get the results I wanted I am happy. I will re-visit this for improvement if I have to. Thanks to all who responded with solutions and suggestions. It has been a good learning experience :)

Edit: mentioned at the bottom I was using another stackoverflow question for guidance. Turns out its the same issue that I don't believe ever got solved after the person edited their question. So I copied the exact same issue into my code: How to know which cell was tapped in tableView using Swift
There's probably many things wrong with my code at this point, but the main issue is the very edit at the bottom of the post this author puts on his question. I know that makes this a duplicate then but no one has answered that. All the accepted answers have the same outcome as my issue.
I'm very new to swift and I'm creating a flashcard type app where tapping on a tableview cell for details shows a term and definition. These terms and definitions are stored in two parallel arrays and the index is supposed to be the indexPath.row.
My issue is that int selectedCell which should be the index of the array for whichever cell the user taps always runs the code to display the term and definition before running the code to find the selected cell.
My earlier error before this was that if I made selected cell an optional (var selectedCell: Int?), the program would crash because its nil. To fix that, I made it var selectedCell: Int = 0 and that worked until I realized that no matter what I tap, the first selectedCell will always be 0.
How can I get the selectedCell before the terms and definitions are displayed.
This is the code inside CardViewController, the controller brought up after the user touches a cell for details. There are only two labels (term and definition) so the code is pretty scarce here.
override func viewDidLoad() {
super.viewDidLoad()
// Testing
print("new selectedCell: \(selectedCell)")
// Update labels for term and definition
termLabel.text = "Term: \n" + cards[selectedCell]
definitionLabel.text = "Definition: \n" + details[selectedCell]
}
The code inside CardTableViewController where the very last override func is what gives me the selectedCell. I have checked that the number is correct when tapped, it just runs after cardviewcontroller apparently.
This is the code for CardTableViewController, where it is tableview cells of each term from the flashcard listed.
Not to be confused with CardViewController which is the little detail flashcard screen that pops up
import UIKit
var cards = [String]()
var details = [String]()
var newCard:String = ""
var newDetail:String = ""
var study = [String]()
var selectedCell: Int = 0
class CardTableViewController: UITableViewController {
#IBOutlet var createCardButton: UIBarButtonItem!
override func viewDidLoad() {
super.viewDidLoad()
}
override func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return cards.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cardCell", for: indexPath)
cell.textLabel?.text = cards[indexPath.row]
return cell
}
#IBAction func cancel(segue:UIStoryboardSegue) {
}
#IBAction func create(segue:UIStoryboardSegue) {
let addCard = segue.source as! AddCardViewController
newCard = addCard.term
newDetail = addCard.definition
print("term: \(addCard.term)")
print("definition: \(addCard.definition)")
cards.append(newCard)
details.append(newDetail)
study.append(newCard)
tableView.reloadData()
}
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
selectedCell = indexPath.row
print("selectedCell: ", selectedCell)
}
}
I know it's out of order because of the print statements I put in. Instead, selectedCell should print before new selectedCell. Notice how new selectedCell will be 0 due to initialization (nil if I didn't initialize it) and then is always lagging one cell touch behind what it should be?
the segues for cancel and create are bar button items on the (details of the flashcard screen). They are unwind segues that I followed some online tutorial on for how to create an text field and unwind.
for background on the addCardViewController and unwind segues, this is the code inside that:
class AddCardViewController: UIViewController {
#IBOutlet weak var cardTerm: UITextField!
#IBOutlet weak var cardDefinition: UITextField!
var term:String = ""
var definition:String = ""
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "createSegue" {
term = cardTerm.text!
definition = cardDefinition.text!
}
}
Here's the printing results for the cell indexes
new selectedCell: 0
selectedCell: 0
new selectedCell: 0
selectedCell: 1
new selectedCell: 1
selectedCell: 1
Honestly not sure if there's a way to call that function first or if I'm choosing the selectedCell wrong (I got the idea off another post on stack overflow: How to know which cell was tapped in tableView using Swift)
Storyboard for my app. Shows the list of cards tableview controller and the card view controller:
So in my storyboard, I set up two ViewControllers (CardsTableViewController and CardViewController)
The segue in between these two view controllers is called CardSegue and is set up to present modally.
The reuse identifier for the prototype UITableViewCell in CardsTableViewController is CardCell.
This is how the CardsTableViewController looks like:
import UIKit
struct Card {
let term: String
let definition: String
}
class CardsTableViewController: UITableViewController {
var selectedCell: Int = 0
let cards: [Card] = [Card(term: "Привет", definition: "Hello"), Card(term: "Да", definition: "Yes")]
override func viewDidLoad() {
super.viewDidLoad()
}
// MARK: - Table view data source
override func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return cards.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "CardCell", for: indexPath)
cell.textLabel?.text = cards[indexPath.row].term
return cell
}
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
selectedCell = indexPath.row
performSegue(withIdentifier: "CardSegue", sender: self)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if let vc = segue.destination as? CardViewController {
let selectedCard = cards[selectedCell]
vc.card = selectedCard
vc.selectedCell = selectedCell
}
}
}
This is the CardViewController:
import UIKit
class CardViewController: UIViewController {
var card: Card = Card(term: "<Set me>", definition: "<Set me>")
var selectedCell: Int = 0
#IBOutlet weak var termLabel: UILabel!
#IBOutlet weak var definitionLabel: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
// Testing
print("new selectedCell: \(selectedCell)")
termLabel.text = "Term: \n" + card.term
definitionLabel.text = "Definition: \n" + card.definition
}
}
I created a Card struct which has a term and a definition, both being Strings.
I created an array of two Cards with two Russian words. This is the data we're working with.
In didSelectRowAt indexPath, I have set up the same setting of "selectedCell", which is defined at the top.
Directly after, I call performSegue, which will send the user to the CardViewController, which will display the term and the definition.
The prepare(for segue) method is always called whenever performSegue is called. In the view controller, if you start typing..."prepare(for...." Xcode will probably fill it out for you.
In this method, I get the selected card, and I pass the card to the CardViewController. In this example, I pass selectedCell, but I don't know if it's really necessary, it depends on what you are trying to achieve, I guess.
This is how the two view controllers should be communicating.
Here's some good information about how to pass information from one view controller to the next: See this section: Passing Data Between View Controllers Using Segues
I've a custom UITableViewCell, in that I've two UILabels & one UIButton. I'm able to load data...and display it as per requirement.
Problem Statement-1: Now problem exist in my UIButton, which is in my UICustomTableViewCell. Due to this I'm unable to handle click event on that UIButton.
Problem Statement-2: On button Click I have to identify the index of that Button click and pass data to next ViewController using segue.
Now have a look on...what did I've tried for this...
Yes, first-of-all I have thought that Binding IBOutlet action in my CustomCell will resolve my problem...but actually it doesn't solved my problem.
After that I've accessed button using .tag and initialised index path.row to it.
But it won't helped me.
So now I'm using Protocol oriented concept using delegate to handle click event on my UIButton which is available in CustomCell.
What did I tried:
SwiftyTableViewCellDelegate:
protocol SwiftyTableViewCellDelegate : class {
func btnAuditTrailDidTapButton(_ sender: LeadCustomTableViewCell)
}
CustomTableViewCell with delegate:
class LeadCustomTableViewCell: UITableViewCell {
#IBOutlet weak var lblMeetingPersonName: UILabel!
#IBOutlet weak var lblPolicyNo: UILabel!
#IBOutlet weak var btnLeadAuditTrail: UIButton!
weak var delegate: SwiftyTableViewCellDelegate?
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
#IBAction func btnAuditTrailTapped(_ sender: UIButton) {
delegate?.btnAuditTrailDidTapButton(self)
}
}
ViewController implementing delegate:
class LeadViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, SwiftyTableViewCellDelegate {
//IBOutlet Connections - for UITableView
#IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
//setting dataSource & delegates of UITableView with this ViewController
self.tableView.dataSource = self
self.tableView.delegate = self
//Reloading tableview with updated data
self.tableView.reloadData()
//Removing extra empty cells from UITableView
self.tableView.tableFooterView = UIView()
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell:LeadCustomTableViewCell = self.tableView.dequeueReusableCell(withIdentifier: "cell") as! LeadCustomTableViewCell
//Assigning respective array to its associated label
cell.lblMeetingPersonName.text = (meetingPersonNameArray[indexPath.section] )
cell.lblPolicyNo.text = (String(policyNoArray[indexPath.section]))
cell.btnLeadAuditTrail.tag = indexPath.section
cell.delegate = self
return cell
}
//This is delegate function to handle buttonClick event
func btnAuditTrailDidTapButton(_ sender: LeadCustomTableViewCell) {
guard let tappedIndexPath = tableView.indexPath(for: sender) else { return }
print("AuditTrailButtonClick", sender, tappedIndexPath)
}
Don't know why this is not working.
Link the touch up inside event in cellForRow by adding the following code:
cell.btnLeadAuditTrail.addTarget(self, action:#selector(btnAuditTrailDidTapButton(_:)), for: .touchUpInside)
I have a custom cell with some simple labels and a UIImage. Everything appears to be set correctly, and stepping through the debugger shows that everything is getting a value and even using the print in the debugger shows that the labels have text. However my table view is still empty when executed. I have been looking at this for too long and cannot figure out the problem.
Here is the cell code
class CurrentFileCell: UITableViewCell {
#IBOutlet weak var nameLabel: UILabel!
#IBOutlet weak var statusImage: UIImageView!
#IBOutlet weak var dateLabel: UILabel!
var currentContent: AircraftContent! {
didSet{
setStyles(Constants.appStyleSetting)
self.nameLabel.text = currentContent.contentName
self.dateLabel.text = currentContent.contentStatus
self.statusImage.image = UIImage(named: "color_label_circle_green")
}
}
override func awakeFromNib() {
super.awakeFromNib()
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
private func setStyles(settings: StyleSettings) {
let tableFont = UIFont(name: settings.bodyFont, size: CGFloat(settings.tableFontSize))
nameLabel.font = tableFont
dateLabel.font = tableFont
// Text color
let tableFontColor = settings.tableFontColor
nameLabel.textColor = tableFontColor
dateLabel.textColor = tableFontColor
}
Here is the ViewController code with a tableview inside.
class CurrentFilesViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
var content: AircraftContent?
#IBOutlet weak var currentFiles: UILabel!
#IBOutlet weak var downloadingLabel: UILabel!
#IBOutlet weak var readyLabel: UILabel!
#IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
self.tableView.delegate = self
self.tableView.dataSource = self
self.content = loadContent()
setStyles(Constants.appStyleSetting)
//self.tableView.reloadData()
// Do any additional setup after loading the view.
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("CurrentFileCell", forIndexPath: indexPath) as? CurrentFileCell
cell?.currentContent = content
return cell!
}
func loadContent() -> AircraftContent {
return (NSKeyedUnarchiver.unarchiveObjectWithFile(AircraftContent.ArchiveURL.path!) as? AircraftContent)!
}
private func setStyles(settings: StyleSettings) {
let titleFont = UIFont(name: settings.bodyFont, size: CGFloat(settings.titleFontSize))
let key = UIFont(name: settings.bodyFont, size: CGFloat(settings.tableFontSize))
currentFiles.font = titleFont
downloadingLabel.font = key
readyLabel.font = key
// Text color
let titleFontColor = settings.titleFontColor
currentFiles.textColor = titleFontColor
downloadingLabel.textColor = titleFontColor
readyLabel.textColor = titleFontColor
}
Here are some images showing the debug location where the cell is not empty, and also printing out the label which has a value, but isn't being shown during simulation.

This is an image showing the prototype cell. The cell has the correct class set as well as the identifier.

Lastly another image showing that the prototype cell is linked to the labels within the CurrentFileCell.

Any help at all with this would be appreciated. I have tried recreating everything but continue to be stumped as it seems like everything is how it should be.
You have to implement the 'heightForRowAtIndexPath' method for the table view
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
let height:CGFloat = 75
return height
}
You may consider registering the custom class as it does not appear that you did. You can do that by using the following code in the viewDidLoad of your View Controller.
tableView.registerClass(CurrentFileCell.self, forCellReuseIdentifier: "cell")
If you are using an external nib you will want to use registerNib instead like so:
tableView.registerNib(UINib(name:"ReplaceWithYourNibName", bundle: nil), forCellReuseIdentifier: "ReuseIdentifier")
Of course, replace ReplaceWithYourNibName and ReuseIdentifier with the appropriate values. In addition, if your nib is in a different bundle specify that instead of nil (nil defaults to the main bundle).
However, do not use both registerClass and registerNib as whichever one you call last will be used and they were designed to be mutually exclusive. Whenever you make a custom UITableViewCell you must use either of the two for it to work unless you have set it explicitly in the storyboard.
Also, you could instead, use prototype cells to define your custom cell, which would, I believe, automatically register the cell. But only if you did not use prototype cells make sure to use registerClass or registerNib.
Good luck! Hope this helps!
If your cell is a static cell, then you need to comment out these methods in UITableViewDataSource:
/* override func numberOfSections(in tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 0
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return 0
} */
I had the same issue.
Data has values and cell rows are showing empty.
I figured it by adding
contentView.addSubview(titleLabel)
where cell values are being set.
I have a table view with a custom cell build in it, the custom cell has two labels and one textfield. When the user edits the textfield then the label2 changes in the current cell. But I want that the value(Label2) in the second cell will also change based on the value in the current cell. Example: Value in the first cell is x, the Value in the second cell should be 2+x. How should I realize that? In my view controller I am using the following code:
var myString = [String]()
#IBOutlet weak var TableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
myString = ["a", "b"]
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return myString.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! CalculationsTableViewCell
tableView.tableFooterView = UIView(frame: CGRectZero) //hide empty cells in UITableView
cell.Label?.text = myString[indexPath.row]
return cell
}
My TableViewCell:
#IBOutlet weak var Label: UILabel!
#IBOutlet weak var Label2: UILabel!
#IBOutlet weak var TextField: UITextField!
#IBAction func TextFieldEditingChanged(sender: AnyObject) {
var value: Double
value = NSString(string: TextField.text!).doubleValue
Label2.text = "\(value)"
}
override func awakeFromNib() {
super.awakeFromNib()
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
Firstly you should / could make use of the delegate pattern to communicate from the cell back to your controller:
create a protocol with a method named e.g. userEnteredNumber
let your view controller conform to that protocol
create a field in the TableViewCell called delegate - its type should the previously created protocol
when setting up the cell in cellForRowAtIndexPath assign self to the delegate property of the cell
as soon as the user enters a value call the delegate method on the previously set delegate
Secondly you have to somehow remember the state of your application. The thing with tableviews is that the iOS can decide to reload the contents of the tableView at any point (theoretically) and your controller has to keep track of the exact content each cell should have.
I do not know what the exact requirements are for your app but you should probably assign the value that gets transmitted via the protocol method to some variable in your viewController. Then you trigger a tableView reloadData and finally you have to alter the cellForRowAtIndexPath method to set the desired properties of some of the cells based on the stored value.
I have created two custom labels in a table cell in order to be able to dynamically resize the cell(s) to it's content. I first tried using the "Subtitle" style and this worked out great except that the cell(s) didn't resize the way i wanted to and it looked really messy.
My question is: how do I access these labels in order to append my value's from my API to them?
View controller code:
import UIKit
class nyheterViewController: UIViewController, UITableViewDataSource, UITableViewDelegate, APIControllerProtocol {
#IBOutlet weak var nyheterTableView: UITableView!
#IBOutlet weak var titleLabel: UILabel!
var searchResultsData: NSArray = []
var api: APIController = APIController()
func JSONAPIResults(results: NSArray) {
dispatch_async(dispatch_get_main_queue(), {
self.searchResultsData = results
print(self.searchResultsData)
self.nyheterTableView.reloadData()
})
}
override func viewDidLoad() {
super.viewDidLoad()
var APIBaseUrl: String = "http://*.se/*/*.php"
var urlString:String = "\(APIBaseUrl)"
//Call the API by using the delegate and passing the API url
self.api.delegate = self
api.GetAPIResultsAsync(urlString, elementName:"news")
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
//print(self.searchResultsData.count)
return self.searchResultsData.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cellIdentifier: String = "nyheterResultsCell"
let cell: UITableViewCell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier) as UITableViewCell
//nyheterTableViewCell.cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier);
//Create a variable that will contain the result data array item for each row
var cellData: NSDictionary = self.searchResultsData[indexPath.row] as NSDictionary
//Assign and display the Title field
var releaseDate: String = cellData["date"] as String
var titleVar: String = cellData["title"] as String
var titleMix: String = "\(titleVar)" + " - " + "\(releaseDate)"
cell.textLabel?.text = titleMix //textLabel worked out fine using "Subtitle" style.
// Get the release date string for display in the subtitle
cell.detailTextLabel?.text = cellData["content"] as String? //Same
return cell
}
}
I understand that I can't access these labels without somehow connecting them to the ViewController. Creating outlets to the ViewController generates an error about that I can't use connections from the prototype cell to the ViewController.
So, i created a new class, called nyheterTableViewCell which i connect to the table cell and connected outlets to my labels.
nyhterTableViewCell code:
import UIKit
class nyheterTableViewCell: UITableViewCell {
#IBOutlet weak var nyhetLabel: UILabel!
#IBOutlet weak var titleLabel: UILabel!
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
}
}
I'm an beginner at Swift-programming and Xcode.
Cheers!
You don't need the labels connected to the view controller. Your example of the custom table view cell looks correct.
To access the label properties, you're going to want to change the line
let cell: UITableViewCell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier) as UITableViewCell
to
let cell: nyheterTableViewCell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier) as nyheterTableViewCell
