My uitableview consists of 10 cells and each cell has 2 uitextfield's.
I need to take values from each uitextfield in each cell and add it to an array
// my custom cell
class MatchTableViewCell: UITableViewCell, UITextFieldDelegate {
#IBOutlet weak var Team2Score: UITextField!
#IBOutlet weak var Team1Score: UITextField!
#IBOutlet weak var Team2: UILabel!
#IBOutlet weak var Image2: UIImageView!
#IBOutlet weak var Image1: UIImageView!
#IBOutlet weak var Team1: 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
}
}
Make sure in the cell initializer for tableviewcontroller that your using your custom cell name and that you've set your identifier correctly. Then just initalize a cell and say something to the effect of
cell.Team2Score.text = "100"
you will need a global array to hold the strings. So..
var wordArray: [String] = []
you will need to add a button within the cell so when you hit the button it will add (append in the input of string (letters) to the array.
You need to add a tag to the button to know which cell it was clicked in.
button.tag = indexPath.row
#IBaction button(sender: UIButton){
var team2Words = Team2Score.text
wordArray.append(team2Words)
// do the samething for Team1Score
// you can use and if statement to check if one or the other one is empty
}
This will give you a lead

I have a custom cell class with two buttons and one label defined in its own class. Am using protocol-delegates to update the value of the label when the button is pressed. But am not able to figure out how to update the UITableView.
protocol customCellDelegate: class {
func didTapDecrementBtn(_ sender: AllCountersTableViewCell)
func didTapIncrementBtn(_ sender: AllCountersTableViewCell)
func updateTableViewCell(_ sender: AllCountersTableViewCell)
}
class AllCountersTableViewCell: UITableViewCell {
#IBOutlet weak var counterValueLbl: UILabel!
#IBOutlet weak var counterNameLbl: UILabel!
#IBOutlet weak var counterResetDateLbl: UILabel!
#IBOutlet weak var counterDecrementBtn: UIButton!
#IBOutlet weak var counterIncrementBtn: UIButton!
weak var delegate: customCellDelegate?
#IBAction func decrementBtnPressed(_ sender: UIButton) {
delegate?.didTapDecrementBtn(self)
delegate?.updateTableViewCell(self)
}
#IBAction func incrementBtnPressed(_ sender: UIButton) {
delegate?.didTapIncrementBtn(self)
delegate?.updateTableViewCell(self)
}
In my ViewController, I have provided the delegate. But reloadData() is not working, so although sender.counterLbl.value is changing its not reflecting on the view.
extension AllCountersVC: customCellDelegate {
func didTapIncrementBtn(_ sender: AllCountersTableViewCell) {
guard let tappedCellIndexPath = tableView.indexPath(for: sender) else {return}
let rowNoOfCustomCell = tappedCellIndexPath[1]
let newValue = String(allCounter[rowNoOfCustomCell].incrementCounterValue(by: allCounter[rowNoOfCustomCell].counterIncrementValue))
sender.counterValueLbl.text = newValue
}
func updateTableViewCell(_ sender: AllCountersTableViewCell) {
allCountersTableView.reloadData()
}
In cellForRow you must set cell.delegate = self for this logic to start working. Its not enough just to make you controller confroms to your custom cell delegate protocol. From your post I assume delegate is always nil in the cell, that is why it does not work.
I'm adding a new TableVIewto the project and I'm also creating a custom class fro the cell. I'm doing as usual : New file/ Cocoa Touch Class / UITableViewCell / name. As soon as I start adding properties I get the error dough properties are declared as!. It doesn't happen on my other custom cell class. Can you see what am I doing wrong with this new class?
No error on this class :
import UIKit
class CalendarTableViewCell: UITableViewCell {
#IBOutlet weak var dayLabel: UILabel!
var cellId: String!
var cellWeekday: Int!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func prepareForReuse() {
super.prepareForReuse()
// Set your default background color, title color etc
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
and the new class that makes xCode complain:
import UIKit
class ProductTableViewCell: UITableViewCell {
#IBOutlet weak var productImageView: UIImageView!
#IBOutlet weak var productIDLabel: UILabel!
#IBOutlet weak var productIDInfoLabel: UILabel!
#IBOutlet weak var categoryLabel: UILabel!
#IBOutlet weak var categoryInfoLabel: UILabel!
#IBOutlet weak var nameLabel: UILabel!
#IBOutlet weak var nameInfoLabel: UILabel!
#IBOutlet weak var priceLabel: UILabel!
#IBOutlet weak var priceInfoLabel: UILabel!
#IBOutlet weak var quantityLabel: UILabel!
#IBOutlet weak var quantityInfoLabel: UILabel!
var productImage: UIImage!
var category: String!
var productId: String!
var name: String!
var price: String
var vendor: String!
var cellId: Int64
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
}
}
It's something I overlooked for sure but I can't spot it.
What should I check?
Your var cellId: Int64 is not initialized. In first cell you explicitly specified that you will initialize it before use with exclamation mark, but not in the second cell.
I have a few UITableViewCell's that have a few different layouts depending on if they're teammates, enemies, etc. But I have to treat each type differently etc. So I tried to cut down on replicated code by using a protocol,
I've created a protocol for a UITableViewCell like so:
protocol ViewCellProtocol {
var teamRank: UILabel! { get set }
var ranking: UILabel! { get set }
var rankDelta: UILabel! { get set }
var upDownIndicator: UILabel! { get set }
var textLabel : UILabel? { get }
}
This is my class:
import UIKit
class TeamStatsTableViewCell: UITableViewCell {
#IBOutlet weak var teamRank: UILabel!
#IBOutlet weak var ranking: UILabel!
#IBOutlet weak var rankDelta: UILabel!
#IBOutlet weak var upDownIndicator: 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
}
}
Then when I try to use it
func playerViewCell(_ tableView: UITableView, indexPath: IndexPath) -> ViewCellProtocol {
let cell = tableView.dequeueReusableCell(withIdentifier: "teamNameCell")! as! TeamStatsTableViewCell
let rank = sections[indexPath.section].data[indexPath.row]["rank"] as? Int
let (rating, ratingDelta) = selectRating(section: indexPath.section, row: indexPath.row)
let indicator = decideRatingIndicator(ratingDelta: ratingDelta, cell: cell)
cell.upDownIndicator?.text = "\(indicator)"
cell.teamRank?.text = "#\(rank!)"
cell.ranking?.text = String(rating)
cell.rankDelta.text = String(format: "%.0f", ratingDelta)
cell.textLabel?.text = sections[indexPath.section].data[indexPath.row]["username"] as? String
return cell as! ViewCellProtocol
}
I get an error:
Could not cast value of type '.TeamStatsTableViewCell' (0x1008d35d8) to '.ViewCellProtocol' (0x10ea37db8).
2018-04-24 22:00:27.137516-0600[434:72294] Could not cast value of type '.TeamStatsTableViewCell' (0x1008d35d8) to '.ViewCellProtocol' (0x10ea37db8).
I wish it would tell me what part it doesn't conform to. Any suggestions? Fairly new to swift kind of looking at protocols like interface{} in Go. Thanks.
Your custom cell class might be implementing all the stuff that's in the protocol, and that'd be enough in objC perhaps, but here you must declare that you implement that protocol explicitly
class TeamStatsTableViewCell: UITableViewCell, ViewCellProtocol {
#IBOutlet weak var teamRank: UILabel!
#IBOutlet weak var ranking: UILabel!
#IBOutlet weak var rankDelta: UILabel!
#IBOutlet weak var upDownIndicator: 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
}
}
You need to declare that TeamStatsTableViewCell conforms to ViewCellProtocol, for example by adding this extension:
extension TeamStatsTableViewCell: ViewCellProtocol { }
I have followed this this tutorial
How to visualize reusable xibs in storyboards using IBDesignable
I have added a label inside the view to change the label and I'm calling the xib inside the custom cell for tableView. So I'm facing this issue,
fatal error: unexpectedly found nil while unwrapping an Optional value
While I’ve added this code inside the view and linked it
#IBOutlet weak var priceLabel: UILabel!
This is how I'm calling it inside the custom cell.
TableViewcell code:
class ProductListBigTableViewCell: UITableViewCell {
#IBOutlet weak var productImage: UIImageView!
#IBOutlet weak var productName: UILabel!
#IBOutlet weak var productQuantity: UILabel!
#IBOutlet weak var productAddButton: BaseButton!
#IBOutlet weak var prodcutPriceView: PriceView!
override func awakeFromNib() {
super.awakeFromNib()
productFirstName.text = "first product"
productFirstQuantity.text = "4 p"
prodcutPriceView.priceLabel.text = ""
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
}
I can figure that the view is not initialised yet so it is nil. I could not find a way or resource how to change a value inside XIB inside the UITableViewCell. So how I can change it and initial the view for the XIB?
I created a custom cell added the actions and outlets.
I want to be able to get the cell indexpath when the cell button is pressed.
I am send data to my parse server and I need to the cell indexPath.row so when someone clicks the button the count for likes or dislikes goes up.
My Custom Cell :
class myTVC: UITableViewCell {
#IBOutlet weak var greenUp: UIButton!
#IBOutlet weak var redDown: UIButton!
#IBOutlet weak var imageViewTVC: UIImageView!
#IBOutlet weak var upVote: UILabel!
#IBOutlet weak var downVote: UILabel!
#IBOutlet weak var saveButton: UIButton!
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
}
#IBAction func voteDownPressed(sender: UIButton) {
print("downVote")
}
#IBAction func voteUpPressed(sender: UIButton) {
print("upVote")
}
}
