How to Set data to second tableview in same Class in swift.I am using two tables in the the same controller one for dropdown and another for listing. I am unable to set data to second table(listing) in class
as else part is not called in cellForRowAtIndexPath. Thanks in Advance
import UIKit
class PunchClockVC: UIViewController , UITableViewDataSource, UITableViewDelegate{
var appdel = UIApplication.sharedApplication().delegate as! AppDelegate
#IBOutlet weak var dropdownTable: UITableView!
#IBOutlet weak var mainTable: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
self.mainTable.registerClass(PunchClockCustomCell.self, forCellReuseIdentifier: "PunchClockCustomCell")
self.dropdownTable.registerClass(UITableViewCell.self, forCellReuseIdentifier: "dropdowncell")
self.dropdownTable.hidden = true
}
#IBAction func textFieldTapped(sender: AnyObject) {
if self.dropdownTable.hidden == true {
self.dropdownTable.hidden = false
}
else{
self.dropdownTable.hidden = false
}
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if tableView == dropdownTable {
return jobArrayID.count
}
return 8
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
if tableView == self.dropdownTable {
let cell = tableView.dequeueReusableCellWithIdentifier("dropdowncell", forIndexPath: indexPath) as UITableViewCell
cell.textLabel?.text = (jobArrayID[indexPath.row] as! String) + "-" + (jobArrayName[indexPath.row] as! String)
return cell
}
else {
let cell1 = tableView.dequeueReusableCellWithIdentifier("PunchClockCustomCell", forIndexPath: indexPath) as! PunchClockCustomCell
if indexPath.row == 0
{
cell1.jobcell?.font = UIFont(name: "MuseoSlab-500", size: 25.0)
cell1.locationcell?.font = UIFont(name: "MuseoSlab-500", size: 25.0)
cell1.timecell?.font = UIFont(name: "MuseoSlab-500", size: 25.0)
cell1.typecell?.font = UIFont(name: "MuseoSlab-500", size: 25.0)
cell1.jobcell?.textColor = UIColor.blackColor()
cell1.locationcell?.textColor = UIColor.blackColor()
cell1.timecell?.textColor = UIColor.blackColor()
cell1.typecell?.textColor = UIColor.blackColor()
cell1.jobcell?.text = "Job"
cell1.locationcell?.text = "Location"
cell1.timecell?.text = "Time"
cell1.typecell?.text = "Type"
// return cell1
}
else {
cell1.jobcell?.text = "Jobdata"
cell1.locationcell?.text = "Locationdata"
cell1.timecell?.text = "Timedata"
cell1.typecell?.text = "OUT"
// return cell1
}
return cell1
}
}
It's quite simple You need to set it only with cellForRowAtIndexPath method but the main thing to do is you need to code like below
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
if tableView == firstTbaleView
//outlet given to first tableView
{
let cell = tableView.dequeueReusableCellWithReuseIdentifier("cell1", forIndexPath: indexPath) as! cust1TableViewCell
cell.imgView.image = images[indexPath.row]
cell.filtLabel.text = self.filtersCount[indexPath.row]
return cell
}}else {
let cell2 = tableView.dequeueReusableCellWithReuseIdentifier("cell2", forIndexPath: indexPath) as! cust2TableViewCell
cell2.imgview.image = UIImage(named: colPhotos[indexPath.row])
cell2.labl.text = colNames[indexPath.row]
// cell2.layer.borderColor = UIColor.blueColor().CGColor
// cell2.layer.borderWidth = 2.0
return cell2
}
and that's it you can ask me for any help..
Lets make this a little safer:
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if tableView == self.dropdownTable {
return jobArray.count
}
else if tableView == self.mainTable {
return = 5
}
//Default return 0. This way if references are broken or change, you won't crash
return 0
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
if tableView == self.dropdownTable {
let cell = tableView.dequeueReusableCellWithIdentifier("dropdowncell", forIndexPath: indexPath) as! UITableViewCell
//configure your cell
return cell
}
else if tableView == self.mainTable {
let cell = tableView.dequeueReusableCellWithIdentifier("PunchClockCustomCell", forIndexPath: indexPath) as! PunchClockCustomCell
//configure your cell
return cell
}
//Shouln't ever reach here, but again, if we refactor somewhere then we'll see an error show up before here.
return UITableViewCell()
}

let cell = tableView.dequeueReusableCell(withIdentifier: CellButton.identifier(), for: indexPath) as! CellButton
cell.build(height: 40, color: .lighterGray())
cell.blockAction = {
let category = categories?[indexPath.row]
let cell = tableView.dequeueReusableCell(withIdentifier:
CellCheck.identifier(), for: indexPath) as!
CellCheck
}
return cell
This is the code I have and when blockAction called (function called when i tap button in cell) I need to build another TableViewCell and remove first that appear
Is there any way of loading it inside same cell and also expand the height by the height of dynamic cell content
You could remove IndexPath and then add add a new indexPath.
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
#IBOutlet weak var tableView: UITableView!
private var buttonTapped: Bool = false
private var selectedIndexPath: IndexPath?
override func viewDidLoad() {
super.viewDidLoad()
tableView.delegate = self
tableView.dataSource = self
tableView.register(UINib(nibName: "TableViewCell", bundle: nil), forCellReuseIdentifier: "TableViewCell")
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 10
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if buttonTapped == true,
let olderIndexPath = selectedIndexPath,
selectedIndexPath == olderIndexPath {
let cell = UITableViewCell()
cell.backgroundColor = .red
return cell
}
let cell = tableView.dequeueReusableCell(withIdentifier: "TableViewCell", for: indexPath) as! TableViewCell
cell.callback = {[weak self] in
self?.buttonTapped = true
self?.selectedIndexPath = indexPath
self?.insertNewCell(indexPath)
}
return cell
}
private func insertNewCell(_ indexPath: IndexPath) {
tableView.beginUpdates()
tableView.deleteRows(at: [indexPath], with: .right)
tableView.insertRows(at: [indexPath], with: .left)
tableView.endUpdates()
}
}
I am creating an application where when a User searches for an item in the TableView they can click on it and a checkmark appears next to it. However, say when I select the first item I have searched for and click it then delete my search the checkmark stays on the first row but for a completely different object, I searched for, to begin with (see images below).
When Searching
When not Searching
var searchingArray = [Symptoms]()
var filteredArray = [Symptoms]()
var selectedSymptoms = [Symptoms]()
var clicked = [String]()
var searchingUnderWay = false
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if let cell = searchingSymptomsTableView.dequeueReusableCell(withIdentifier: "ExtraSymptoms", for: indexPath) as? ExtraSymptomCell {
let searchingArrays: Symptoms!
if searchingUnderWay {
searchingArrays = self.filteredArray[indexPath.row]
} else {
searchingArrays = self.searchingArray[indexPath.row]
}
cell.updateUI(symptomNames: searchingArrays)
return cell
} else {
return UITableViewCell()
}
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let selectedRow: Symptoms!
let symptomName: String!
let cell : UITableViewCell = tableView.cellForRow(at: indexPath)!
if searchingUnderWay {
selectedRow = filteredArray[indexPath.row]
symptomName = filteredArray[indexPath.row].name as String
if clicked.contains(symptomName) {
cell.accessoryType = .none
let indexNumber = clicked.index(of: symptomName)
clicked.remove(at: indexNumber!)
if let element = selectedSymptoms.index(where: { $0.name == selectedRow.name }) {
selectedSymptoms.remove(at: element)
}
} else {
clicked.append(symptomName)
cell.accessoryType = .checkmark
searchingSymptomsTableView.reloadData()
selectedSymptoms.append(selectedRow)
}
} else {
selectedRow = searchingArray[indexPath.row]
symptomName = searchingArray[indexPath.row].name as String
if clicked.contains(symptomName) {
cell.accessoryType = .none
let indexNumber = clicked.index(of: symptomName)
clicked.remove(at: indexNumber!)
if let element = selectedSymptoms.index(where: { $0.name == selectedRow.name }) {
selectedSymptoms.remove(at: element)
}
} else {
clicked.append(symptomName)
cell.accessoryType = .checkmark
searchingSymptomsTableView.reloadData()
selectedSymptoms.append(selectedRow)
}
print(clicked)
print(selectedSymptoms)
}
}
I wish for the item I searched using the searchbar to still be checked when you delete the search.
Many thanks
Welcome to TableViewController logic. It seems really strange, but it works correct)
You need to override prepareForReuse() method in your ExtraSymptomCell. And clear all the values your cell contains including accessoryType
override func prepareForReuse() {
super.prepareForReuse()
accessoryType = .none
}
In your tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath):
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if let cell = searchingSymptomsTableView.dequeueReusableCell(withIdentifier: "ExtraSymptoms", for: indexPath) as? ExtraSymptomCell {
let symptomName: String!
let searchingArrays: Symptoms!
if searchingUnderWay {
searchingArrays = self.filteredArray[indexPath.row]
symptomName = filteredArray[indexPath.row].name as String
} else {
searchingArrays = self.searchingArray[indexPath.row]
symptomName = filteredArray[indexPath.row] as String
}
cell.updateUI(symptomNames: searchingArrays)
if clicked.contains(symptomName) {
cell.accessoryType = .checkmark
} else {
cell.accessoryType = .none
}
return cell
} else {
return UITableViewCell()
}
}
Since UITableViewCell are reused, the checkmark will appear in a cell when you reload Table Data.
In cellForRowAt set the accessoryType to .none, to remove a previously checked cell checkmark:
let cell : UITableViewCell = tableView.cellForRow(at: indexPath)!
cell.accessoryType = .none
This will remove the check from the previous search.
Im using a tableview to display an array of strings. When I click on a particular row, I want it to be highlighted with a checkmark. When I deselect a row, I want the checkmark to be removed. When I press a button, I want the rows that are currently highlighted to be passed out in an array(newFruitList).
My problem is that when I click the first row, the last is highlighted. When I uncheck the first row, the last is unchecked, as if they are the same cell?
How do I overcome this?
Also, the way I am adding and removing from my new array, is this the correct way to go about doing this?
Thanks
My Code:
class BookingViewController: UIViewController, ARSKViewDelegate, UITextFieldDelegate, UITableViewDelegate, UITableViewDataSource {
#IBOutlet weak var table: UITableView!
let fruits = ["Apples", "Oranges", "Grapes", "Watermelon", "Peaches"]
var newFruitList:[String] = []
override func viewDidLoad() {
super.viewDidLoad()
self.table.dataSource = self
self.table.delegate = self
self.table.allowsMultipleSelection = true
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return fruits.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
var cell = table.dequeueReusableCell(withIdentifier: "Cell")
if cell == nil{
cell = UITableViewCell(style: .subtitle, reuseIdentifier: "Cell")
}
cell?.textLabel?.text = fruits[indexPath.row]
return cell!
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
newFruitList.append(fruits[indexPath.row])
if let cell = tableView.cellForRow(at: indexPath) {
cell.accessoryType = .checkmark
}
}
func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {
if let index = newFruitList.index(of: fruits[indexPath.row]) {
newFruitList.remove(at: index)
}
if let cell = tableView.cellForRow(at: indexPath) {
cell.accessoryType = .none
}
}
#IBAction func bookButtonPressed(_ sender: UIButton) {
//testing purposes
for i in stride(from: 0, to: newFruitList.count, by: 1){
print(newFruitList[i])
}
}
They are probably the same cell because you use dequeueReusableCell and it reuses old cells.
use:
override func prepareForReuse() {
super.prepareForReuse()
}
To reset the cell and it should be fine.
As for the save and send mission. Create an pre-indexed array that you can populate.
var selected: [Bool] = []
var fruits: [Fruit] = [] {
didSet {
selected = Array(repeating: false, count: fruits.count)
}
}
And in your didSelectItemAt you do:
selected[indexPath.item] = !selected[indexPath.item]
UITableView reuses the cell that is already present and hence you will see that duplicate check mark, so to solve this issue you need to clear the cell states while loading cell. for that you can create a model with property to track the states of your selected cells
So your fruit model must be like below
class Fruit{
var name:String
var isSelected:Bool
init(name:String){
isSelected = false
self.name = name
}
}
Then you will have table view populated with Fruit list
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
var cell = table.dequeueReusableCell(withIdentifier: "Cell")
if cell == nil{
cell = UITableViewCell(style: .subtitle, reuseIdentifier: "Cell")
}
let model = fruits[indexPath.row]
cell?.textLabel?.text = model.name
if(model.isSelected){
cell.accessoryType = .checkmark
}
else{
cell.accessoryType = .none
}
return cell!
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
newFruitList.append(fruits[indexPath.row])
if let cell = tableView.cellForRow(at: indexPath) {
cell.accessoryType = .checkmark
var model = fruits[indexPath.row]
model.isSelected = true
}
func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {
if let index = newFruitList.index(of: fruits[indexPath.row]) {
newFruitList.remove(at: index)
}
if let cell = tableView.cellForRow(at: indexPath) {
cell.accessoryType = .none
var model = fruits[indexPath.row]
model.isSelected = false
}
}
My development environment is swift3, xcode8.
I'm making a list app like Apple's message app.
When I select the list in the table view, I go to the detail page (through the seg) and now I want to implement multiple delete functions, but there's a problem. When I edit mode, I can see the selection window, but if I select that selection window, just go to the detail page.
Maybe before going to the detail page through Seg. I think I should make it a multiple choice. What should I do?
Make sure you conform something like below code;
class TableviewController:UITableViewController{
override func viewDidLoad() {
super.viewDidLoad()
var isMultipleSelectionActive = false
var selectedItems: [String: Bool] = [:]
tableView.allowsMultipleSelectionDuringEditing = true
tableView.setEditing(true, animated: false)
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath)
cell.textLabel?.text = "\(indexPath.row)"
return cell
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 10
}
func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
let selectedItem = items.objectAtIndex(indexPath.row)
//add to selectedItems
selectedItems[selectedItem] = true
}
func tableView(tableView: UITableView, didDeselectRowAtIndexPath indexPath: NSIndexPath) {
let selectedItem = items.objectAtIndex(indexPath.row)
// remove from selectedItems
selectedItems[selectedItem] = nil
}
func getStatusOfSelectedItems() {
for item in selectedItems {
println(item)
}
}
//You should override shouldPerformSegueWithIdentifier and return false if isMultipleSelectionActive is true
override func shouldPerformSegue(withIdentifier identifier: String?, sender: Any?) -> Bool {
if let identifierName = identifier {
if identifierName == "NameOfYourSegueIdentifier" {
if isMultipleSelectionActive {
return false
}
}
}
return true
}
}
This code used to select the multiple row
class TableViewController: UITableViewController
{
var lastSelectedIndexPath = NSIndexPath(forRow: -1, inSection: 0)
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
let cell = tableView.dequeueReusableCellWithIdentifier("myCell", forIndexPath: indexPath)
// Configure the cell...
cell.textLabel!.text = "row: \(indexPath.row)"
if cell.selected
{
cell.selected = false
if cell.accessoryType == UITableViewCellAccessoryType.None
{
cell.accessoryType = UITableViewCellAccessoryType.Checkmark
}
else
{
cell.accessoryType = UITableViewCellAccessoryType.None
}
}
return cell
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath)
{
let cell = tableView.cellForRowAtIndexPath(indexPath)
if cell!.selected
{
cell!.selected = false
if cell!.accessoryType == UITableViewCellAccessoryType.None
{
cell!.accessoryType = UITableViewCellAccessoryType.Checkmark
}
else
{
cell!.accessoryType = UITableViewCellAccessoryType.None
}
}
}
I have a TableViewController with 3 sections with their own headers.
Now I want before inserting any cell, check a property and then add the cell into different sections.
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// Table view cells are reused and should be dequeued using a cell identifier.
let cellIdentifier = "TasksTableViewCell"
guard let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as? TasksTableViewCell else {
fatalError("The dequeued cell is not an instance of TasksTableViewCell.")
}
// Fetches the appropriate task for the data source layout.
let task = tasks[indexPath.row]
cell.nameLabel.text = task.name
cell.photoImageView.image = task.photo
cell.timeControl.text = task.lengthDisplay.replacingOccurrences(of: "Length: ", with: "")
if(task.importanceLevel == 0){
// add cell to section 0
}
else if(task.importanceLevel == 1){
// add cell to section 1
}
// Configure the cell...
return cell
}
Can u see the comment, is there any way to do that?
Thank you very much
You can create a model and pass empty count arrays at first for each section and row in data source methods.
And then initialize the count and fill arrays their then reload your table view.
I hope you know there is numberOfSections method too.
I think this code will help you:
let arr = [5,2,7,10,2]
override func viewDidLoad() {
super.viewDidLoad()
}
// MARK: - Table view data source
override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 5
}
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
// #warning Incomplete implementation, return the number of rows
return arr[section]
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("celldata", forIndexPath: indexPath)
cell.textLabel?.text = "section \(indexPath.section)"
cell.detailTextLabel?.text = "Rows \(indexPath.row)"
return cell
}
override func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let view = UIView(frame: CGRect(x: 0, y: 0, width: self.tableView.frame.width, height: 20))
let lbl = UILabel(frame: CGRect(x: 5, y: 5, width: self.tableView.frame.width, height: 15))
lbl.text = "\(section)"
view.backgroundColor = UIColor.grayColor()
view.addSubview(lbl)
return view
}
You can try it like this
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if(indexPath.section == 0){
let cellIdentifier = "TasksTableViewCell"
guard let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as? TasksTableViewCell else {
fatalError("The dequeued cell is not an instance of TasksTableViewCell.")
}
// Fetches the appropriate task for the data source layout.
let task = tasks[indexPath.row]
cell.nameLabel.text = task.name
cell.photoImageView.image = task.photo
cell.timeControl.text = task.lengthDisplay.replacingOccurrences(of: "Length: ", with: "")
return cell
}
else if(indexPath.section == 1)
let cellIdentifier = "TasksTableViewCell1"
guard let cell = tableView.dequeueReusableCell(withIdentifier: cellIdentifier, for: indexPath) as? TasksTableViewCell1 else {
fatalError("The dequeued cell is not an instance of TasksTableViewCell.")
}
// Fetches the appropriate task for the data source layout.
let task = tasks[indexPath.row]
cell.nameLabel.text = task.name
cell.photoImageView.image = task.photo
cell.timeControl.text = task.lengthDisplay.replacingOccurrences(of: "Length: ", with: "")
return cell
}
}
