I am new to programming and currently working on a newsfeed like app. I had a normal Table view up and running fine, but want to try it now with a costume cell type. So I created one and thought connecting the labels the usual way would be perfectly fine, but I was wrong. So I am wondering how I can let my Text label connect to my view controller, so I can use my custom cell.
class ViewController: BaseViewController, UITableViewDelegate, UITableViewDataSource {
#IBOutlet var newsfeedTableView: UITableView!
var ref: DatabaseReference!
var posts = [String]()
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return (posts.count)
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = UITableViewCell(style: UITableViewCell.CellStyle.default, reuseIdentifier: "cell")
//here is where I need the custom label to get the posts
cell.textLabel?.text = posts[indexPath.row]
cell.textLabel?.font = UIFont.boldSystemFont(ofSize: 18.0)
return cell
}
}
Create subclass of UITableViewCell and connect IBOutlets to this class
class YourCell: UITableViewCell {
#IBOutlet weak var customLabel: UILabel!
...
}
don't forget to set class of your prototype cell in storyboard:
then in cellForRowAt data source method downcast your dequeued cell as YourCell
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! YourCell
then you have access to YourCell outlets
cell.customLabel.text = "SomeText"
...
I'm assuming that you are using Storyboard.
First of all, you should understand that there is little difference when you use own custom table cell. In that case, in the method "cellForRowAtIndexPath", after dequeue your cell, you just have to typecast table cell like 'as! YourCustomTableCellClass'. After this line, you can access each property of this class.
First, design your table cell on Storyboard whatever you want.
Now, make a subclass of UITableViewCell and assign this class to your prototype custom cell which you have designed on Storyboard. Also, don't forget to set "reuse identifier in Storyboard table cell.
Then connect your outlets with custom cell class from Storyboard.
Now you can use code like this:
class YourTableCellClass: UITableViewCell {
// I'm using these outlets as a sample, but you have to connect them from Storyboard.
var leftTextLabel: UILabel!
var rightTextLabel: UILabel!
}
class YourTableController: UITableViewController {
override func viewDidLoad() {
super.viewDidLoad()
}
// MARK: - TableView Delegate & DataSource
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 1 // return your number of rows here...
}
override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 100 // return the height for the row here.....or you can set height from Storyboard if you have fix height of all rows.
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "CellIdentifier", for: indexPath) as! YourTableCellClass
cell.leftTextLabel.text = "Text" // Set text here....
cell.rightTextLabel.text = "Text" // Set text here....
return cell
}
}
I have created prototype custom header cell for a tableView with a button on it. I am trying to get the indexPath of the cell when the button is tapped, but I don't receive it. Any idea what I am doing wrong here?
protocol MediaHeaderCellDelegate: class {
func editPost(cell: MediaHeaderCell)
}
class MediaHeaderCell: UITableViewCell {
weak var delegate: MediaHeaderCellDelegate?
#IBAction func moreOptionsAction(_ sender: UIButton) {
delegate?.editPost(cell: self)
}
}
class NewsfeedTableViewController:UITableViewController, MediaHeaderCellDelegate {
func editPost(cell: MediaHeaderCell) {
guard let indexPath = tableView.indexPath(for: cell) else {
print("indexpath could not be given")
return}
}
override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView?
{
let cell = tableView.dequeueReusableCell(withIdentifier: Storyboard.mediaHeaderCell) as! MediaHeaderCell
cell.delegate = self
cell.media = media[section]
return cell
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell
{
let cell = tableView.dequeueReusableCell(withIdentifier: Storyboard.mediaCell, for: indexPath) as! MediaTableViewCell
cell.currentUser = currentUser
cell.media = media[indexPath.section]
cell.delegate = self
return cell
}
}
So this is actually all about learning what section a section header belongs to?? Here’s what I do. I have a header class:
class MyHeaderView : UITableViewHeaderFooterView {
var section = 0
}
I register it:
self.tableView.register(
MyHeaderView.self, forHeaderFooterViewReuseIdentifier: self.headerID)
I use and configure it:
override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let h = tableView
.dequeueReusableHeaderFooterView(withIdentifier: self.headerID) as! MyHeaderView
// other stuff
h.section = section // *
return h
}
Now if the header view is tappable or contains a button or whatever, learning what section this is the header of is trivial.
Your immediate issue is that you are using a table cell as a section header view. That should not be done. Once you resolve that, your next task is to determine the table section from the header view whose button was tapped.
First, change your MediaHeaderCell to be a header view that extends UITableViewHeaderFooterView and update your protocol accordingly:
protocol MediaHeaderViewDelegate: class {
func editPost(view: MediaHeaderView)
}
class MediaHeaderView: UITableViewHeaderFooterView {
weak var delegate: MediaHeaderViewDelegate?
#IBAction func moreOptionsAction(_ sender: UIButton) {
delegate?.editPost(cell: self)
}
}
Then you need to register the header view in your view controller.
Then update your viewForHeaderInSection:
override func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let view = tableView.dequeueReusableHeaderFooterView(withIdentifier: Storyboard.mediaHeaderView) as! MediaHeaderView
view.delegate = self
view.media = media[section]
view.tag = section
return view
}
And last, update your protocol method implementation:
func editPost(view: MediaHeaderView) {
let section = view.tag
// do something
}
There is one possible issue with this. If your table allows sections to be added or removed, then it is possible that a header view's tag could be wrong when the button is tapped.
I a tableView class that displays a text in cells. I need to be able to touch/click text in a cell and create an action (display the next table view) based on the text in the cell clicked. Class is as follows:
import UIKit
class SecondViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
#IBOutlet var tableView: UITableView!
let textCellIdentifier = "TextCell"
let catRet = XnYCategories.mainCats("sport")
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
}
// MARK: UITextFieldDelegate Methods
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return catRet.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier(textCellIdentifier, forIndexPath: indexPath) as! UITableViewCell
let row = indexPath.row
cell.textLabel?.text = catRet[row]
return cell
}
// MARK: UITableViewDelegate Methods
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
tableView.deselectRowAtIndexPath(indexPath, animated: true)
let row = indexPath.row
println(catRet[row])
}
}
I would like to add upon Linus answer, as it has deprecated in latest Swift addition.
Swift 4:
In the myCell add this Recogniser,
let tapGesture = UITapGestureRecognizer(target: self, action: #selector(yourVC.yourfuncName))
myCell.addGestureRecognizer(tapGesture)
In the same VC, implement your function,
func yourfuncName(){
//Do whatever you want here
}
If you have a hard-coded amount of cells, you can create a UIGestureRecognizer and add it to the cell created:
let tapGesture = UITapGestureRecognizer(target: self, action: "tapped:")
myCell.addGestureRecognizer(tapGesture)
In it's target you can do whatever you want to do.
You can get your cell using
let currentCell = tableView.cellForRowAtIndexPath(indexPath) as UITableViewCell
To get your text you could use
var selectedText = currentCell.textLabel?.text
the main role is to display the playlists names in table view, but it show me word "name" in about 500 cells!
I can make a simple errors, because i only learning swift, and it is my first programming language
There is the code:
import UIKit
import MediaPlayer
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
#IBOutlet var tableView: UITableView!
var tableData = MPMediaQuery.playlistsQuery()
var songname: NSString = MPMediaPlaylistPropertyName
override func viewDidLoad() {
super.viewDidLoad()
self.tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "cell")
self.tableView.reloadData()
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.tableData.items.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell: UITableViewCell = self.tableView.dequeueReusableCellWithIdentifier("cell") as UITableViewCell
cell.textLabel.text = songname
return cell
}
func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) {
println("Row \(indexPath.row) selected")
}
}
Your problem is that you're displaying MPMediaPlaylistPropertyName in the cell which is most likely just the constant string "name"
What you need to do is set the cell's textLabel with the actual name of the playlist which would look something like this in your cellForRowAtIndexPath method
Replace
cell.textLabel.text = songname
With
let playlist: MPMediaPlaylist = tableData.collections[indexPath.row] as MPMediaPlaylist
let playlistName = playlist.valueForProperty(MPMediaPlaylistPropertyName) as NSString
cell.textLabel.text = playlistName;
Also, you need to make sure you're getting the count from the collections of the tableData so in your number of rowsInSectionMethod change:
return self.tableData.items.count
to
return self.tableData.collections.count
For A bit more understanding, what we're doing in the cellForRowAtIndexPath now is:
Getting a specific MPMediaPlaylist item for that particular row
Getting the Name of the playlist and assigning it to a variable
Assigning that name to the cells textLabel
Let me know if you have any other questions
You have to cleanup the cell data since you are re-using the cells,
Right after line
var cell: UITableViewCell = self.tableView.dequeueReusableCellWithIdentifier("cell") as UITableViewCell
do
cell.textLabel.text = ""
I have a custom cell class with a couple of IBOutlets. I have added the class to the storyboard. I have connected all my outlets. my cellForRowAtIndexPath function looks like this:
override func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as SwipeableCell
cell.mainTextLabel.text = self.venueService.mainCategoriesArray()[indexPath.row]
return cell
}
Here is my custom cell class:
class SwipeableCell: UITableViewCell {
#IBOutlet var option1: UIButton
#IBOutlet var option2: UIButton
#IBOutlet var topLayerView : UIView
#IBOutlet var mainTextLabel : UILabel
#IBOutlet var categoryIcon : UIImageView
init(style: UITableViewCellStyle, reuseIdentifier: String!) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
}
}
When I run the app, all my cell are empty. I have logged out self.venueService.mainCategoriesArray() and it contains all the correct strings. I have also tried putting an actual string equal to the label, and that produces the same result.
What am I missing? Any help is appreciated.
Custom Table View Cell Example
Tested with Xcode 9 (edit also tested on 11 / 12 Beta 2) and Swift 4 (edit: also tested on 5.2)
The asker of the original question has solved their problem. I am adding this answer as a mini self contained example project for others who are trying to do the same thing.
The finished project should look like this:
Create a new project
It can be just a Single View Application.
Add the code
Add a new Swift file to your project. Name it MyCustomCell.swift. This class will hold the outlets for the views that you add to your cell in the storyboard.
import UIKit
class MyCustomCell: UITableViewCell {
#IBOutlet weak var myView: UIView!
#IBOutlet weak var myCellLabel: UILabel!
}
We will connect these outlets later.
Open ViewController.swift and make sure you have the following content:
import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
// These strings will be the data for the table view cells
let animals: [String] = ["Horse", "Cow", "Camel", "Sheep", "Goat"]
// These are the colors of the square views in our table view cells.
// In a real project you might use UIImages.
let colors = [UIColor.blue, UIColor.yellow, UIColor.magenta, UIColor.red, UIColor.brown]
// Don't forget to enter this in IB also
let cellReuseIdentifier = "cell"
#IBOutlet var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
}
// number of rows in table view
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.animals.count
}
// create a cell for each table view row
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell:MyCustomCell = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier) as! MyCustomCell
cell.myView.backgroundColor = self.colors[indexPath.row]
cell.myCellLabel.text = self.animals[indexPath.row]
return cell
}
// method to run when table view cell is tapped
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
print("You tapped cell number \(indexPath.row).")
}
}
Setup the storyboard
Add a Table View to your view controller and use auto layout to pin it to the four sides of the View Controller. Then drag a Table View Cell onto the Table View. And then drag a View and a Label onto the Prototype cell. (You may need to select the Table View Cell and manually set the Row Height to something taller in the Size inspector so that you have more room to work with.) Use auto layout to fix the View and the Label how you want them arranged within the content view of the Table View Cell. For example, I made my View be 100x100.
Other IB settings
Custom class name and Identifier
Select the Table View Cell and set the custom class to be MyCustomCell (the name of the class in the Swift file we added). Also set the Identifier to be cell (the same string that we used for the cellReuseIdentifier in the code above.
Hook Up the Outlets
Control drag from the Table View in the storyboard to the tableView variable in the ViewController code.
Do the same for the View and the Label in your Prototype cell to the myView and myCellLabel variables in the MyCustomCell class.
Finished
That's it. You should be able to run your project now.
Notes
The colored views that I used here could be replaced with anything. An obvious example would be a UIImageView.
If you are just trying to get a TableView to work, see this even more basic example.
If you need a Table View with variable cell heights, see this example.
This is for who are working custom cell with .xib
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell{
let identifier = "Custom"
var cell: CustomCell! = tableView.dequeueReusableCellWithIdentifier(identifier) as? CustomCel
if cell == nil {
tableView.registerNib(UINib(nibName: "CustomCell", bundle: nil), forCellReuseIdentifier: identifier)
cell =tableView.dequeueReusableCellWithIdentifier(identifier) as? CustomCell
}return cell}
I have the same problem.
Generally what I did is the same as you.
class dynamicCell: UITableViewCell {
#IBOutlet var testLabel : UILabel
init(style: UITableViewCellStyle, reuseIdentifier: String) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
}
override func awakeFromNib() {
super.awakeFromNib()
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
}
and in the uitableviewcell method:
func tableView(tableView: UITableView!, cellForRowAtIndexPath indexPath: NSIndexPath!) -> UITableViewCell! {
var cell :dynamicCell = tableView.dequeueReusableCellWithIdentifier("cell") as dynamicCell
cell.testLabel.text = "so sad"
println(cell.testLabel)
return cell;
}
and yeah the tableview shows nothing! But guess what, it actually shows something...because the log I get from the println(cell.testLabel) shows that all the Labels are actually displayed out.
BUT! their Frames is strange, which have something like this:
frame = (0 -21; 42 21);
so it has a (0,-21) as (x,y), so that means the label just appears at somewhere outside the bound of the cell.
so I try to add adjust the frame manually like this:
cell.testLabel.frame = CGRectMake(10, 10, 42, 21)
and sadly, it doesn't work.
---------------update after 10 min -----------------
I DID IT.
so, it seems that the problem comes from the Size Classes.
Click on your .storyboard file and go to the File Inspector Tab
UNCHECK THE Size Classes checkbox
and finally, my "so sad"Label comes out!
Thanks for all the different suggestions, but I finally figured it out. The custom class was set up correctly. All I needed to do, was in the storyboard where I choose the custom class: remove it, and select it again. It doesn't make much sense, but that ended up working for me.
Last Updated Version is with xCode 6.1
class StampInfoTableViewCell: UITableViewCell{
#IBOutlet weak var stampDate: UILabel!
#IBOutlet weak var numberText: UILabel!
override init?(style: UITableViewCellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
}
required init(coder aDecoder: NSCoder) {
//fatalError("init(coder:) has not been implemented")
super.init(coder: aDecoder)
}
override func awakeFromNib() {
super.awakeFromNib()
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
}

Results
Uncheck "Size Classes" checkbox works for me as well, but you could also add the missing constraints in the interface builder. Just use the built-in function if you don't want to add the constraints on your own. Using constraints is - in my opinion - the better way because the layout is independent from the device (iPhone or iPad).
It is Purely swift notation an working for me

cell = nib[0] as? CustomCell
}
return cell!
