The problem is that there is nothing in your view controller called self.tableView. Its name is completedCaseTableView. So change this:
if let indexPath = self.tableView.indexPathForSelectedRow {
to this:
if let indexPath = self.completedCaseTableView.indexPathForSelectedRow {

I have two custom table views. I need to pass first and second cell datas of DestinationTableView to first cell of MyCartTableView. How can I make transition between this two table view cells with outside of tableView.
I did tableView.indexPathForSelectedRow but this time I need to make with UIButtonoutside of tableView.
Below triggered with tableView cell.
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "cellForFoodSegue" {
if let destinationViewController = segue.destination as? DetailViewController
{
let indexPath = self.mainTableView.indexPathForSelectedRow!
var foodNameArray: String
var foodPriceArray: Double
foodNameArray = foodNames[indexPath.row]
foodPriceArray = foodPrices[indexPath.row].purchaseAmount
destinationViewController.detailFoodName = foodNameArray
destinationViewController.detailFoodPrice = foodPriceArray
}
}
}
I tried below code but I did not success passing data with button.
#IBAction func addBasket(_ sender: Any) {
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if(segue.identifier == "addToCartSegue") {
if let addToCartVC = segue.destination as? MyCartViewController {
let selectedCell = sender as! UITableViewCell
let indexPath = self.detailTableView.indexPath(for: selectedCell)
var foodNameArray: String
var foodPriceArray: Double
foodNameArray = foodNames[indexPath.row]
foodPriceArray = prices[indexPath.row].purchaseAmount
addToCartVC.fromDetailFoodName = foodNameArray
addToCartVC.fromDetailFoodPrice = prices[(indexPath?.row)!].purchaseAmount
}
}
}
Belows my MyViewController codes. Which is my added objects when tapped to addBasket button
class MyCartViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
var fromDetailFoodName: [String?] = []
var fromDetailFoodPrice = Double()
var nameLabel = MyCartTableViewCell()
#IBOutlet weak var myCartTableView: UITableView!
#IBOutlet weak var totalPriceLabel: UILabel!
let foodNames = [
"Hamburger big mac",
"Cemal",
"Emre",
"Memo"
]
//TODO-: Delete my cart
#IBAction func deleteMyCart(_ sender: Any) {
}
//TODO: - Approve my cart
#IBAction func approveCart(_ sender: Any) {
}
override func viewDidLoad() {
super.viewDidLoad()
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return section == 0 ? 1 : foodNames.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "myCartCell", for: indexPath) as! MyCartTableViewCell
cell.myCartFoodNameLabel?.text = fromDetailFoodName.description
cell.myCartFoodPriceLabel?.text = "\(fromDetailFoodPrice)₺"
return cell
}
}
You should get the index path of the data you want to pass in func addBasket(_ sender: Any).
For example, you can save index path as a property that referenced in class.
class StartViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
var selectedIndexPath: IndexPath?
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
selectedIndexPath = indexPath
}
#IBAction func addBasket(_ sender: Any) {
if let indexPath = selectedIndexPath {
let destinationVC = MyCartViewController()
destinationVC.detailFoodName = foodNames[indexPath.row]
destinationVC.detailFoodPrice = foodPrices[indexPath.row].purchaseAmount
}
}
}
In MyCartViewController which is destination VC.
class MyCartViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
var fromDetailFoodNames: [String?] = []
var fromDetailFoodPrices: [Double?] = []
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if indexPath.section == 1 && indexPath.last! <= fromDetailFoodPrices.indices.last! {
let cell = myCartTableView.dequeueReusableCell(withIdentifier: "myCartCell", for: indexPath) as! MyCartTableViewCell
let name = fromDetailFoodNames[indexPath.row]?.description ?? ""
let price = fromDetailFoodPrices[indexPath.row]
cell.myCartFoodNameLabel?.text = name
cell.myCartFoodPriceLabel?.text = "\(price)₺"
return cell
}
}
}
BTW, for better coding, you can implement OOP concept in your code. detailFoodName and detailFoodPrice should be in ONE object. Besides, var foodNameArray: String naming could be confusing. Rename it as var foodName: String would be better.

Intent intent = new Intent(context, FragmentDemoActivity.class);
intent.putExtra("videoId", resultp.get(Main.VIDEO_ID));
context.startActivity(intent);
// Get the position

});
return itemView;
Can anyone help me please?
You need to implement prepareForSegue method
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath:
IndexPath)
{
tableView.deselectRow(at: indexPath, animated: true)
performSegue(withIdentifier: "secondView", sender: indexPath.row)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
var next = segue.destinationViewController as! PlayTableViewController
next.indexOfCell = sender as? Int
}
//
class PlayTableViewController:UITableViewController
{
var indexOfCell:Int?
}
I'm trying to segue from one UITableView to another UITableView. I want to segue and pass the myCell.textLabel?.text value of the selected cell to the second UITableView.
The code for my first UITableView (MenuTypeTableViewController and the code for my second UITableView (TypeItemsTableViewController) is also below.
I'm fully aware this involves the prepareForSegue function which currently I've not created, purely because I'm unsure where I override it and how to pass in the textLabel value to it.
Hope my question makes sense, I will update with suggestions and edits.
class MenuTypeTableViewController: UITableViewController, MenuTypeServerProtocol {
//Properties
var cellItems: NSArray = NSArray()
var menuType: MenuTypeModel = MenuTypeModel()
override func viewDidLoad() {
super.viewDidLoad()
let menuTypeServer = MenuTypeServer()
menuTypeServer.delegate = self
menuTypeServer.downloadItems()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
// MARK: - Table view data source
override func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return cellItems.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cellIdentifier: String = "cellType"
let myCell: UITableViewCell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier)!
let item: MenuTypeModel = cellItems[indexPath.row] as! MenuTypeModel
myCell.textLabel?.text = item.type
return myCell
}
func itemsDownloaded(items: NSArray) {
cellItems = items
tableView.reloadData()
}
}
class TypeItemsTableViewController: UITableViewController, TypeItemsServerProtocol {
//Properties
var cellItems: NSArray = NSArray()
var typeItemList: TypeItemsModel = TypeItemsModel()
override func viewDidLoad() {
super.viewDidLoad()
let typeItemsServer = TypeItemsServer()
typeItemsServer.delegate = self
typeItemsServer.downloadItems()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}

let myCell: UITableViewCell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier)!

myCell.textLabel?.text = item.name
return myCell

tableView.reloadData()

Hi try the following set of code, I have added few additional changes in your code make use of it, I hope it will solve your issue.
I have added only the extra codes which you needed
class TypeItemsTableViewController: UITableViewController, TypeItemsServerProtocol {
// Add this variable in this class and use it whereever you needed it in this class
var selectedItem: String?
override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
// Get the selected cell
let selectedCell = tableView.cellForRow(at: indexPath)
// Now maintain the text which you want in this class variable
selectedItem = selectedCell?.textLabel?.text
// Now perform the segue operation
performSegue(withIdentifier: "TypeItemsTableViewController", sender: self)
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if segue.identifier == "TypeItemsTableViewController" {
let destinationVC = segue.destination as? TypeItemsTableViewController
destinationVC?.selectedItem = self.selectedItem // Pass the selected item here which we have saved on didSelectRotAt indexPath delegate
}
}
In Second class:
class TypeItemsTableViewController: UITableViewController, TypeItemsServerProtocol {
// Add this variable in this class and use it whereever you needed it in this class
var selectedItem: String?
What you can do is to make a variable in your second UITableView
var String: labelSelected?
then in you prepare for segue method just set the labelSelected to the value of the cell.
refToTableViewCell.labelSelected = youCell.textlabel?.text
If you set up a segue in storyboards from one storyboard to another, you can use the code below in your prepareForSegue method. You'll need to add a testFromMenuTableViewController property to your TypeItemsTableViewController.
override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
if let destination = segue.destination as? TypeItemsTableViewController,
let path = self.tableView.indexPathForSelectedRow,
let cell = self.tableView.cellForRow(at: path),
let text = cell.textLabel?.text {
destination.textFromMenuTypeTableViewController = text
}
}

I am having trouble passing data from the selected row in my TableView to the other ViewController.
class SectionsTableViewController: UITableViewController {
var sections: [Sections] = SectionsData().getSectionsFromData()
override func viewDidLoad() {
super.viewDidLoad()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// MARK: - Table view data source
override func numberOfSections(in tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return sections.count
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return sections[section].items.count
}
override func tableView(_ tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
return sections[section].headings
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "sectionCell", for: indexPath)
// Configure the cell...
cell.textLabel?.text = sections[indexPath.section].items[indexPath.row]
return cell
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?)
{
if (segue.identifier == "sectionCell")
{
let upcoming: Sjekkliste = segue.destination as! Sjekkliste
let indexPath = self.tableView.indexPathForSelectedRow!
let titleString = Sections(title: "", objects: [""]) as? String
upcoming.titleString = titleString
self.tableView.deselectRow(at: indexPath, animated: true)
}
This is where my problem is: let titleString = Sections(title: "", objects: [""]) as? String
It would be preferred if the title and objects was passed separately.
This is my data setup:
class SectionsData {
var myArray: [AnyObject] = []
func getSectionsFromData() -> [Sections] {
var sectionsArray = [Sections]()
let Generell = Sections(title: "Animals", objects:
["Cat", "Dog", "Lion", "Tiger"])
sectionsArray.append(Generell)
return sectionsArray
This line suggests you subclassed String into Sections. Why are you subclassing String? If Sections is not a subclass of string then this line will fail.
let titleString = Sections(title: "", objects: [""]) as? String
I'm assuming you want something similar to this:
let selectedSection:Sections = Sections(title: "", objects: [""])
upcoming.titleString = selectedSection.title
The above suggests a "title" property on the Sections object is what you are looking to set as the "titleString" property of the next view controller.
Unrelated to the original question you should lowercase "Generell". Best practices suggests only class names should start with a capital letter. I also suggest implementing the didSelectRow method to pick your data. The results should looks similar to this:
var selectedSection:Sections? //goes at top
public func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
tableView.deselectRow(at: indexPath, animated: true)
self.selectedSection = self.sections[indexPath.section]
}
override func prepare(for segue: UIStoryboardSegue, sender: Any?){
if (segue.identifier == "sectionCell"){
let upcoming: Sjekkliste = segue.destination as! Sjekkliste
if let section = self.selectedSection{
upcoming.titleString = section.title
}
}
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
let cell = tableView.dequeueReusableCellWithIdentifier("SearchTableViewCellIdentifier") as! SearchTableViewCell
var item = self.searchResult[indexPath.row] as? PFObject
cell.post = item
return cell
}
func tableView(tableView: UITableView, didSelectRowAtIndex rowIndex: Int)
{
let indexPath = tableView.indexPathForSelectedRow()
let currentCell = tableView.cellForRowAtIndexPath(indexPath!)! as UITableViewCell
println(currentCell.textLabel!.text)
}
I am not getting the actual value. I am getting nil on printing currentCell.textLabel!.text
just remove override
class yourclassName: UIViewController, UITableViewDataSource, UITableViewDelegate
var cod: AnyObject?
override func viewDidLoad() {
super.viewDidLoad()
self.tableView.delegate = self
self.tableView.dataSource = self
}
func tableView(tableView: UITableView, didSelectRowAtIndex rowIndex: Int)
{
//Handle row selection
// choice 1
let indexPath = tableView.indexPathForSelectedRow();
// if it is not work follow second option
cod = self.searchResult[indexPath.row] as? PFObject
// choice 2
cod = self.searchResult[rowIndex] as? PFObject
println(cod)
self.performSegueWithIdentifier("yourSegueName", sender: self)
}
override func prepareForSegue(segue: UIStoryboardSegue!, sender: AnyObject!) {
if (segue.identifier == "yourSegueName") {
var svc = segue!.destinationViewController as secondViewController;
svc.toPass = cod
}
}
in your second VC create this string
var toPass:String!
