I would like to add a boolean toggle to know whether the button has been pressed (will save this value to core data (also would like to save cell data to core data if true and delete from core data if false)) I am not sure how to do this. any help would be greatly appreciated. if all the code from the view controller is required leave a comment and I will do so (I have setup xcdatamodel already).
#IBAction func buttonTapped(_ sender:UIButton) {
var superView = sender.superview
while !(superView is UITableViewCell) {
superView = superView?.superview
}
let cell = superView as! UITableViewCell
if let indexpath = tableView.indexPath(for: cell){
print(indexpath)
}
}
Well I build a simple project and I figured something out using protocols,
First you define a protocol like this:
protocol cellDidRequestSaving {
func saveOrDelete(indexpath : Int)
}
First in your cell you define you button like this :
class TableViewCell: UITableViewCell {
var delegate: cellDidRequestSaving?
var indexPath = 0 //come from the parent
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 didTap(_ sender: Any) {
// this protocol defined in the parent
delegate?.saveOrDelete(indexpath: indexPath)
}
}
now in you tableViewController you use the protocol like this:
class TableViewController: UITableViewController, cellDidRequestSaving {
var cellStat = [Int:Bool]()
override func viewDidLoad() {
super.viewDidLoad()
// Uncomment the following line to preserve selection between presentations
// self.clearsSelectionOnViewWillAppear = false
// Uncomment the following line to display an Edit button in the navigation bar for this view controller.
// self.navigationItem.rightBarButtonItem = self.editButtonItem
}
// MARK: - Table view data source
override func numberOfSections(in tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return 3
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath) as! TableViewCell
cell.indexPath = indexPath.row
cell.delegate = self
// Configure the cell...
return cell
}
func saveOrDelete(indexpath: Int) {
if let status = cellStat[indexpath], status {
print(indexpath, "delete")
cellStat[indexpath] = !status
}
else {
print(indexpath, "save")
cellStat[indexpath] = true
}
}
This is a simple project but you can get the hole idea about how to do it. Also, notice the protocol definition and usage so you wont miss anything.
and the out put is this
Add a property to your custom cell, for example:
var indexPath: IndexPath = IndexPath(row: -1, section: -1) //The -1 just know when it is not set yet
And in cellForRow in your tableView:
cell.indexpath = indexPath
Supposing that buttonTapped is defined in your custom cell class:
#IBAction func buttonTapped(_ sender:UIButton) {
print(indexpath)
}
Add a delegate method to your cell - (void)myCell:(MyCell *)cell didTapButton:(UIButton *)button
So then in your VC you can work backwards from the cell object.
- (void)myCell:(MyCell *)cell didTapButton:(UIButton *)button
{
NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];
MyObject *object = [self.dataSource objectAtIndexPath:indexPath];
// Do something with the knowledge that the button in the cell for the object was tapped...
// For example
object.tapped = YES;
[object.managedObjectContext save:NULL];
}
Just need to convert to swift ;)
I have a Viewcontroller with a Searchbar at the top with a tableview below. The tableview has a custom cell with 2 labels in it. My problem is that when i run the app and i select a row/cell everything inside the cell disappears. I then force the blank cell outside the visible area of the tableview, so it will be re-used. That's when everything inside the cell is back. Does anyone know why it behaves like this?
My Custom cell class (ContactCell.swift):
import UIKit
class ContactCell: UITableViewCell {
#IBOutlet var lblContactName: UILabel!
#IBOutlet var lblContactTitle: 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
}
}
My ViewDidLoad function:
override func viewDidLoad() {
super.viewDidLoad()
tableView.dataSource = self
tableView.delegate = self
}
My Delegate and Datasource:
extension contactsTabelViewController: UITableViewDelegate, UITableViewDataSource {
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 6
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("contactCell", forIndexPath: indexPath) as! ContactCell
if let label = cell.lblContactName{
label.text = "This is a name"
}
if let label3 = cell.lblContactTitle{
label3.text = "This is a title"
}
return ContactCell()
}
}
The problem that caused this problem was that i returned ContactCell() instead of the variable cell
Solution was:
Change this:
return ContactCell()
to this:
return cell
in the cellForRowAtIndexPath function.
I would like to make a UITableView in a xib file so i have an Custom Alert (Simple Alert) and there are Custom Views and they are in xib. So i make a UITableView in the View of the xib file but the Problem is i show the Alert and it´s shows no data. I am new by the xib.files so i have no idea what i make wrong. It´s stranger with the xib.files because when i add a Button in the View and i would print a text on tapped it´s print anything so the Button not reacted. The BookTableView and the subview and view are bound with the files-owner.
Have anyone an idea what i make wrong ?
Thanks for your Help.
So here was my code for Show the Alert with the custom View:
#IBAction func PlayTapped(sender: AnyObject) {
let AlertView = TableViewAlertController(nibName: "TableViewAlertController", bundle: nil)
let AlertTableView = SimpleAlert.Controller(view: AlertView.view, style: .Alert)
showAlert(AlertTableView)
}
Here the code from the ViewController with the xib.file TableView:
import UIKit
import SimpleAlert
class TableViewAlertController: UIViewController {
let items = ["item1", "item2", "item3", "item4"]
required init(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)!
}
override init(nibName nibNameOrNil: String!, bundle nibBundleOrNil: NSBundle!) {
subView = UIView()
super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
}
convenience init() {
self.init(nibName: "TableViewAlertController", bundle: nil)
}
#IBOutlet var subView: UIView!
#IBOutlet var BookTableView: UITableView!
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return items.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = UITableViewCell()
cell.textLabel!.text = items[indexPath.row]
return cell
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
print("Table Cell clicked")
}
}
Thanks for your Help :)
Please try to create the UITableViewCell like this
First register a class for the tableview cell
tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "DefaultCell")
or if you have create xib for tableview cell
tableView.registerNib(UINib(nibName: "yourNib", bundle: nil), forCellReuseIdentifier: "DefaultCell")//same identifier as you have set in 'Reuse identifier' in the cell's xib
in cellForRowAtIndexPath create cell like this:
let cell = tableView.dequeueReusableCellWithIdentifier("DefaultCell")!
Please keep the Cell Identifier name same else if will crash
I constantly am trying to determine the third cell from the top of my table view. Basically, what that means is, the third cell from the top will always look different from all the others (i.e. the text color will change etc.).
I figured since the cells are reused, I would always be able to access the third cell like this:
if (indexPath.row == 2) {
}
Unfortunately, it doesn't seem to be working like that. When I go ahead and print the indexPath.row the numbers continue to increase all the way from 0 to 12... Now this is understandable since it is that cells row, but how may I go about accessing the third row always from the top. Here is the original approach I took:
override func scrollViewDidScroll(scrollView: UIScrollView) {
let indexPath: NSIndexPath = self.tableView.indexPathsForVisibleRows![0]
if (indexPath.row == 2) {
// Print or whatever
}
}
}
So how can I go about accessing the third row always from the top of the tableView?
Thank you!
Here is an example project. I tried running it in the simulator and it seems to work fine.
Here is a screenshot of XCode so you can see Main.Storyboard.
Also here is a copy of the code in ViewController.swift:
import UIKit
class ViewController: UIViewController, UIScrollViewDelegate, UITableViewDataSource, UITableViewDelegate {
#IBOutlet weak var tableView: UITableView!
var indexOfThirdVisible: Int!
override func viewDidLoad() {
super.viewDidLoad()
tableView.dataSource = self
tableView.delegate = self
// Do any additional setup after loading the view, typically from a nib.
self.navigationController?.navigationBar.barStyle = .BlackTranslucent
self.navigationController?.navigationBar.tintColor = UIColor.orangeColor()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func scrollViewDidScroll(scrollView: UIScrollView) {
let indexPath = self.tableView.indexPathsForVisibleRows![0]
indexOfThirdVisible = indexPath.row + 2
let cell = tableView.cellForRowAtIndexPath(NSIndexPath(forRow: indexOfThirdVisible, inSection: indexPath.section)) as! TableViewCell
cell.label.textColor = UIColor.orangeColor()
let cellAbove = tableView.cellForRowAtIndexPath(NSIndexPath(forRow: indexOfThirdVisible - 1, inSection: indexPath.section)) as! TableViewCell
let cellBelow = tableView.cellForRowAtIndexPath(NSIndexPath(forRow: indexOfThirdVisible + 1, inSection: indexPath.section)) as! TableViewCell
cellAbove.label.textColor = UIColor.whiteColor()
cellBelow.label.textColor = UIColor.whiteColor()
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 100
}
// heightForRowAtIndexPath
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
return 100
}
// configure cell
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell")!
return cell
}
}
Here is TableViewCell.swift:
import UIKit
class TableViewCell: UITableViewCell {
#IBOutlet weak var label: 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
}
}
Sorry if the indentation is messed up.
Have a good day and let me know if you need any more help!
I just implemented only logic, you can customise it little bit according to you.
func scrollViewDidEndDragging(scrollView: UIScrollView, willDecelerate decelerate: Bool) {
let indexPath : NSIndexPath = (tv.indexPathsForVisibleRows as! NSArray).objectAtIndex(0) as! NSIndexPath
let thirdRow = indexPath.row + 2
if thirdRow <= dataArr.count{// dataArr is your no of rows
let thirdIndexPath = NSIndexPath(forRow: thirdRow, inSection: 0)
let cell = tv.cellForRowAtIndexPath(thirdIndexPath)
// ---- here you can perform any task with third cell----
}
}
And please let me know if anything is wrong
I want to use a UITableview with different custom tableViewCells. My 3 cells are as such:
Cell1: should have an image and a label.
Cell2: should have two labels.
Cell3: should have a dayPicker.
I don't want to code a tag for the cells. How can I manage this in Swift. Do I have to code my own class for every cell? Can I use one tableviewController? How can I populate data in different cells?
I would like to generate a tableView, like a contact app of an iOS device.
Let me start with answering your questions first.
Do I have to code an own class for every cell?=> Yes, I believe so. At least, I would do that way.
Can I use one tableviewController?=> Yes, you can. However, you can also have a table view inside your View Controller.
How can I populate data in different cells? => Depending on the conditions, you can populate data in different cells. For example, let's assume that you want your first two rows to be like the first type of cells. So, you just create/reuse first type of cells and set it's data. It will be more clear, when I show you the screen shots, I guess.
Let me give you an example with a TableView inside a ViewController. Once you understand the main concept, then you can try and modify anyway you want.
Step 1: Create 3 Custom TableViewCells. I named it, FirstCustomTableViewCell, SecondCustomTableViewCell, ThirdCustomTableViewCell. You should use more meaningful names.
Step 2: Go the Main.storyboard and drag and drop a TableView inside your View Controller. Now, select the table view and go to the identity inspector. Set the "Prototype Cells" to 3. Here, you just told your TableView that you may have 3 different kinds of cells.
Step 3:
Now, select the 1st cell in your TableView and in the identity inspector, put "FirstCustomTableViewCell" in the Custom class field and then set the identifier as "firstCustomCell" in the attribute inspector.
Do the same for all others- Set their Custom Classes as "SecondCustomTableViewCell" and "ThirdCustomTableViewCell" respectively. Also set the identifiers as secondCustomCell and thirdCustomCell consecutively.
Step 4: Edit the Custom Cell Classes and add outlets according to your need. I edited it based on your question.
P.S: You need to put the outlets under the class definition.
So, In the FirstCustomTableViewCell.swift, under the
class FirstCustomTableViewCell: UITableViewCell {
you would put your label and image view outlets.
#IBOutlet weak var myImageView: UIImageView!
#IBOutlet weak var myLabel: UILabel!
and in the SecondCustomTableViewCell.swift, add the two labels like-
import UIKit
class SecondCustomTableViewCell: UITableViewCell {
#IBOutlet weak var myLabel_1: UILabel!
#IBOutlet weak var myLabel_2: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
}
and the ThirdCustomTableViewCell.swift should look like-
import UIKit
class ThirdCustomTableViewCell: UITableViewCell {
#IBOutlet weak var dayPicker: UIDatePicker!
override func awakeFromNib() {
super.awakeFromNib()
}
override func setSelected(selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
}
}
Step 5: In your ViewController, create an Outlet for your TableView and set the connection from storyboard. Also, you need to add the UITableViewDelegate and UITableViewDataSource in the class definition as the protocol list.
So, your class definition should look like-
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
After that attach the UITableViewDelegate and UITableViewDatasource of your table view to your controller. At This point your viewController.swift should look like-
import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
#IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
P.S: If you were to use a TableViewController rather than a TableView inside a ViewController, you could have skipped this step.
Step 6: Drag and drop the image views and labels in your cell according to the Cell class. and then provide connection to their outlets from storyboard.
Step 7: Now, write the UITableViewDatasource's required methods in the view controller.
import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
#IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 3
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
if indexPath.row == 0 {
let cell: UITableViewCell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "firstCustomCell")
//set the data here
return cell
}
else if indexPath.row == 1 {
let cell: UITableViewCell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "secondCustomCell")
//set the data here
return cell
}
else {
let cell: UITableViewCell = UITableViewCell(style: UITableViewCellStyle.Default, reuseIdentifier: "thirdCustomCell")
//set the data here
return cell
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
Swift 3.0 + update with minimum code
Basic concept:
Create a table view with dynamic cell prototypes. Assign identifier and create custom table view cell class for each cell prototype. Initiate and show custom cells in table view's delegate method.
1. Create cells on storyboard
Drag a tableView to your view controller, add prototype cells to it, and then drop UI element to your table view cells, add constraint properly if needed.
2. Create custom UITableViewCell classes
Add the following code to your project. I am putting it right above the view controller class.
class FirstTableCell: UITableViewCell {
}
class SecondTableCell: UITableViewCell {
}
class ThirdTableCell: UITableViewCell {
}
3. Assign custom class and identifier to cell prototypes
For each of the cell prototypes in storyboard, assign the custom class created from step 2, and then enter an unique identifier.
4. Connect UI elements to swift code
Control drag the table view and connect to the view controller class. Control drag the UI elements that get added to cell prototypes on step 1, and connect to the corresponding table view cell class.
5. Add code to view controller and control the table view
Make your view controller conform to table view delegate
class YourViewController: UIViewController, UITableViewDataSource, UITableViewDelegate
In viewDidLoad, set up table view's delegate and data source.
override func viewDidLoad() {
super.viewDidLoad()
self.tableView.dataSource = self
self.tableView.delegate = self
}
Finally, add two delegate methods to control your table view, as per minimum requirement.
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 3
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.row == 0 {
let cell = tableView.dequeueReusableCell(withIdentifier: "firstTableCell") as! FirstTableCell
// Set up cell.label
return cell
} else if indexPath.row == 1 {
let cell = tableView.dequeueReusableCell(withIdentifier: "secondTableCell") as! SecondTableCell
// Set up cell.button
return cell
} else {
let cell = tableView.dequeueReusableCell(withIdentifier: "thirdTableCell") as! ThirdTableCell
// Set up cell.textField
return cell
}
}
6. Give it a try :)
I recommend to use this simple and easy to use library, I made for Table and Collection views. You can add as many types of cells as you want and achieve more clean ViewControllers without boilerplate code.
https://github.com/deniskakacka/DKDataSources
For UI on first picture, all your code in ViewController is this:
lazy var dataSource = DKTableDataSource<CellType>(
models: [
DisclosureCellModel(title: "Disclosure 1", action: .action1),
TextFieldCellModel(title: "TextField 1", placeholder: "Placeholder 1"),
SwitchCellModel(title: "Switch 1", isOn: true),
BannerCellModel(imageName: "placeholder"),
SwitchCellModel(title: "Switch 2", isOn: false),
BannerCellModel(imageName: "placeholder"),
DisclosureCellModel(title: "Disclosure 2", action: .action2),
TextFieldCellModel(title: "TextField 2", placeholder: "Placeholder 2"),
BannerCellModel(imageName: "placeholder")
]
)
// in `viewDidLoad`
dataSource.registerCells(for: tableView)
tableView.dataSource = dataSource
Swift 5
Create 3 Custom TableViewCells. I named it,
FirstTableViewCell, SecondTableViewCell,
ThirdTableViewCell
Add All 3 Custom Cell Classes and add outlets according to your need.
I have added in below code.
class FirstTableViewCell: UITableViewCell {
#IBOutlet weak var myImageView: UIImageView!
#IBOutlet weak var myLabel: UILabel!
static let cellIdentifier = "FirstTableViewCell"
static let cellNib = UINib(nibName: "FirstTableViewCell", bundle: Bundle.main)
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
}
}
3: In your ViewController, create an Outlet for your TableView. Also, you need to add the UITableViewDelegate and UITableViewDataSource in the class definition.
#IBOutlet weak var tableView: UITableView! {
didSet {
tableView.delegate = self
tableView.dataSource = self
tableView.register(FirstTableViewCell.cellNib, forCellReuseIdentifier: FirstTableViewCell.cellIdentifier)
tableView.register(SecondTableViewCell.cellNib, forCellReuseIdentifier: SecondTableViewCell.cellIdentifier)
tableView.register(ThirdTableViewCell.cellNib, forCellReuseIdentifier: ThirdTableViewCell.cellIdentifier)
}
}
4.Now, write the UITableViewDatasource's required methods in the view controller.
extension ViewController: UITableViewDelegate,UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 3
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.row == 0 {
guard let cell = tableView.dequeueReusableCell(withIdentifier: FirstTableViewCell.cellIdentifier, for: indexPath) as? FirstTableViewCell else { return UITableViewCell() }
return cell
}else if indexPath.row == 1 {
guard let cell = tableView.dequeueReusableCell(withIdentifier: SecondTableViewCell.cellIdentifier, for: indexPath) as? SecondTableViewCell else { return UITableViewCell() }
return cell
}else {
guard let cell = tableView.dequeueReusableCell(withIdentifier: ThirdTableViewCell.cellIdentifier, for: indexPath) as? ThirdTableViewCell else { return UITableViewCell() }
return cell
}
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 50 //According requirement
}
}
Your code will look like below(View Controller Code)
class ViewController: UIViewController {
#IBOutlet weak var tableView: UITableView! {
didSet {
tableView.delegate = self
tableView.dataSource = self
tableView.register(FirstTableViewCell.cellNib, forCellReuseIdentifier: FirstTableViewCell.cellIdentifier)
tableView.register(SecondTableViewCell.cellNib, forCellReuseIdentifier: SecondTableViewCell.cellIdentifier)
tableView.register(ThirdTableViewCell.cellNib, forCellReuseIdentifier: ThirdTableViewCell.cellIdentifier)
}
}
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
}
}
extension ViewController: UITableViewDelegate,UITableViewDataSource {
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 3
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.row == 0 {
guard let cell = tableView.dequeueReusableCell(withIdentifier: FirstTableViewCell.cellIdentifier, for: indexPath) as? FirstTableViewCell else { return UITableViewCell() }
return cell
}else if indexPath.row == 1 {
guard let cell = tableView.dequeueReusableCell(withIdentifier: SecondTableViewCell.cellIdentifier, for: indexPath) as? SecondTableViewCell else { return UITableViewCell() }
return cell
}else {
guard let cell = tableView.dequeueReusableCell(withIdentifier: ThirdTableViewCell.cellIdentifier, for: indexPath) as? ThirdTableViewCell else { return UITableViewCell() }
return cell
}
}
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 50 //According requirement
}
}
The above answers are the best answers, but there are TONS of reasons to get this issue. Here is another potential solution for anyone with this problem:
My problem was that I was segueing to the ViewController class and not the storyboard view. So my reference to the storyboard cell was meaningless, since the storyboard wasn't being used.
I was doing this:
let viewControllerB = SubViewController()
viewControllerB.passedData = diseases[indexPath.row].name
navigationController?.pushViewController(viewControllerB, animated: true)
And I needed to do something like this:
let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
let nextViewController = storyBoard.instantiateViewController(withIdentifier: "SubViewStoryboardController") as! SubViewController
nextViewController.passedData = diseases[indexPath.row].name
self.present(nextViewController, animated:true, completion:nil)
Hope this helps someone.
If you're using custom XIBs as TableView Cells then follow the below code
//Write in viewDidLoad()
let nib = UINib(nibName: "PrinterTVC", bundle: nil)
tableView.register(nib, forCellReuseIdentifier: "CELL1")
let nib1 = UINib(nibName: "SelectAndEditTVC", bundle: nil)
tableView.register(nib1, forCellReuseIdentifier: "CELL2")
UITableViewController is inheriting UIViewController that already has UITableviewDataSource & UITableviewDelegate mapped on itself.
You might subclass UITableViewController or use a TableView inside your ViewController.
After that you must implement required methods(cellForRowAtIndexPath and numberOfRowsInSection) which are declared in the UITableviewDataSource.
Also in storyboard, you need to create cell prototypes with unique Id.
There are basic types of cell, with (title, subtitle for instance) - you can use them too if you don't need special configuration.
So, for picker, yes, you need to create your own custom cell. Create necessary custom UITableViewCell class holding date picker and make sure to use delegate to send back the desired result back to your ViewController.
