I've created a tableView with a registered Cell with reuseIdentifier as "cell". I've added this tableView to superview as subview.
private let tableView: UITableView = {
let table = UITableView()
table.register(UITableViewCell.self, forCellReuseIdentifier: "cell")
return table
}()
I've comforted the protocol functions for TableViewCellDelegate and DataSource as below. But still when I do run the app it only shows my tableView but not the cells which should write "Hello". Why this might be happening?
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return notifications.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let model = notifications[indexPath.row]
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
cell.textLabel?.text = "Hello"
return cell
}
Do check with your notifications array is it empty or not if you are fetching it from api make sure to call tableView.reloadData()
have you added your tableView into view ?
Add code below in the ViewController and it should work
override func viewDidLoad() {
super.viewDidLoad()
tableView.dataSource = self
tableView.delegate = self
}
I would like for the user to tap a cell within UITableViewController B and then have the text from the cell sent to display in a cell inside of UITableViewController A which would replace its default text. However I am having trouble doing so. Both of the UITableViewController A & B are in a UINavigationController. selectedName is the String I would like to send from B to A
Here is the code from UITableViewControllerB didSelectRowAt
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
selectedIndexPath = indexPath
tableView.register(UITableViewCell.self, forCellReuseIdentifier: "Cell")
tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath as IndexPath)
tableView.register(UINib(nibName: "BBcell", bundle: nil), forCellReuseIdentifier: "Cell")
tableView.cellForRow(at: indexPath)?.accessoryType = .checkmark
selectedName = nameArray[indexPath.row]
print(selectedName)
let infoTVC = InfoTableViewController()
infoTVC.name = selectedName
}
Here is the code from UITableViewController A
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
tableView.register(UITableViewCell.self, forCellReuseIdentifier: "Cell")
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell", for: indexPath as IndexPath) if indexPath.section == 1 {
cell.textLabel?.text = "Choose Name" // This is where I set the default text
cell.accessoryType = UITableViewCell.AccessoryType.disclosureIndicator
}
return cell
}
This is a very rudimentary example that has many shortcomings and utilizes some practices breaking SOLID principles, but fundamentally should work. Don't take this as the final end all answer, but instead as a starting point to move forward from:
import UIKit
// declare the delegate protocol
protocol TableViewControllerSubclassBDelegate: AnyObject {
func tableViewControllerB(_ controller: TableViewControllerSubclassB, touched indexPath: IndexPath, withStringInfo newStringValue: String)
}
// table view controller where the content ends up
class TableViewControllerSubclassA: UITableViewController {
var tableArrayContents: [String] = []
}
// table view controller where the user touches an entry
class TableViewControllerSubclassB: UITableViewController {
//...
weak var delegate: TableViewControllerSubclassBDelegate?
//...
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
// this is quite prone to fail if everything is not perfectly set - beware
guard let stringInfo = tableView.cellForRow(at: indexPath)?.textLabel?.text else { return }
delegate?.tableViewControllerB(self, touched: indexPath, withStringInfo: stringInfo)
}
}
// you'll need to subclass your navigation controller with something like this
class NavigationControllerSubclass: UINavigationController {
// force unwrap is generally frowned upon. there are better solutions, but this is a simplified answer
var tvcA: TableViewControllerSubclassA!
var tvcB: TableViewControllerSubclassB!
override func viewDidLoad() {
super.viewDidLoad()
// populate the table view controller properties - not the cleanest way
for viewController in viewControllers {
if let typeA = viewController as? TableViewControllerSubclassA {
tvcA = typeA
} else if let typeB = viewController as? TableViewControllerSubclassB {
tvcB = typeB
}
}
tvcB.delegate = self
}
}
// conforming to delegates/protocols in an extension is a great way to organize your code
extension NavigationControllerSubclass: TableViewControllerSubclassBDelegate {
func tableViewControllerB(_ controller: TableViewControllerSubclassB, touched indexPath: IndexPath, withStringInfo newStringValue: String) {
tvcA.tableArrayContents[indexPath.row] = newStringValue
tvcA.tableView.reloadRows(at: [indexPath], with: .automatic)
// you could also go the heavyhanded approach of tvcA.tableView.reloadData() if necessary
}
}
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 am using firebase database and have a table view showing name, age, location, and image of user at index path.row. How would I go about showing another view when the cell is clicked to the users profile with more information and photos of the user. here is the code for my tableView.
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return userList.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "prefCell", for: indexPath) as! SFPTableViewCell
let user = userList[indexPath.row]
cell.name.text = userList[indexPath.row].name
cell.location.text = userList[indexPath.row].location
if let imageURL = user.image {
cell.imageOne.loadImageUsingCacheWithUrlString(urlString: imageURL)
}
return cell
}
}
Using Code use didSelectRowAtIndexPath.
or
Using Storyboard:
step 1: select tableview cell.
step 2: Control + click mouse and drag in destination view.
step 3: Give Any of segue.
step 4: Done.
Add this below code
override func tableView(_ tableView: UITableView, didSelectRowAtindexPath: IndexPath){
let detailVC = storyboard.instantiateViewControllerWithIdentifier("MyDetailVC") as MyDetailVC // get the obect of other VC
detailVC.myImage = <your_image> // assign your image which you wanted to send to other VC.
self.navigationController?.pushViewController(detailVC,animated: true // Push to other VC
}
in MyDetailVC.swift
var myImage : UIImage? // Create variable of image type in required VC where you wanted to send data
Now use your Image in MyDetailVC.swift.
Any further query you can ask.
Just used UITableViewDelegate method "didSelectRowAtIndexPath" and send image to other view controller with its indexPath
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let sb = UIStoryboard(name: "Main", bundle: nil)
let detailVC = sb.instantiateViewController(withIdentifier: "ImageVC") as! DetailViewController
detailVC.strImage = self.arrImage[indexPath.row]
self.navigationController?.pushViewController(detailVC, animated: true)
}
In DetailViewController take one variable
var strImage : String = ""
and assgin this variable to UIImagView
imgView.image = UIImage(named: strImage)
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)
}
}

switch (indexPath.row % 3) {
case 0:
return tableView.dequeueReusableCell(aClass: TableViewCell1.self, for: indexPath) { cell in
cell.textLabel?.text = "\(cell.classForCoder)"
}
case 1:

cell.textLabel?.text = "\(cell.classForCoder)"
}
}
}
}
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
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell

if (cell == nil)
{
var nib:Array = NSBundle.mainBundle().loadNibNamed("CustomCell", owner: self, options: nil)
cell = nib[0] as? CustomCell
}
return cell!
}
