It appears my loop seems to load all the images taken from a feed into the image view but sets only the very last image from the feed into all cells I'm not sure how to stop this and grab a image for each cell and set it. I'm new to swift and I've sorta jumped right in to programming.. heres the code of interest any help is appreciated
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! BlogPost

// cell.textLabel?.text = blogPost.postImageLink

I am making a shopping app but I've come to a problem.
So far I've been json parsing, making a the tableview cell but I've come to an error where it says out of range:
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "hello", for: indexPath) as! DisplayShopTableCellTableViewCell
// Configure the cell...
cell.userLbl.text = namee[indexPath.row] //Index out of range
cell.passLbl.text = myprice[indexPath.row]
let imagedata = try! Data(contentsOf: mySecond[indexPath.row].imageUrl!)
cell.tablecellimageview.image = UIImage(data: imagedata)
return cell
}
This is my display shop table cell:
class DisplayShopTableCellTableViewCell: UITableViewCell {
#IBOutlet weak var userLbl: UILabel!
#IBOutlet weak var passLbl: UILabel!
#IBOutlet weak var tablecellimageview: UIImageView!
Parsing
func extracted(){
guard let url = URL(string: "http://rajeshrmohan.com/sport.json")
else {
return
}
let task = URLSession.shared.dataTask(with: url){
(data,response,error) in
guard let dataResponse = data,
error == nil else {
print(error?.localizedDescription ?? "Response Error")
return
}
do {
let decoder = JSONDecoder()
let model = try decoder.decode(FullClothes.self, from: dataResponse)
//print(model)
for i in 0..<model.item.count{
self.namee.append(model.item[i].name!)
self.myprice.append(String(model.item[i].price!))
self.myphoto.append(model.item[i].image!)
}
DispatchQueue.main.async {
self.tableView.reloadData()
}
}
catch let parsingError {
print("Error", parsingError)
}
}
task.resume()
}
I think the parsing is done in a wrong way, additionally, as El Tomato commented, why using multiple arrays for constructing a cell, one more comment, configuring cell shouldn't be done inside cellForRowAt, it would be better done within cell itself.
Check the following code snippet and let me know if you need any help withh it.
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "hello", for: indexPath) as! DisplayShopTableCellTableViewCell
// Configure the cell...
cell.bind(self.myData[indexPath.row])
return cell
}
class DisplayShopTableCellTableViewCell: UITableViewCell {
#IBOutlet weak var userLbl: UILabel!
#IBOutlet weak var passLbl: UILabel!
#IBOutlet weak var tablecellimageview: UIImageView!
func bind(_ cellData: Item) {
self.userLbl.text = cellData.name
self.passLbl.text = String(cellData.price)
guard let imageURL = URL(string: "\(cellData.image)") else {
preconditionFailure("Invalid static URL string: \(cellData.image)")
}
guard let imagedata = try? Data(contentsOf: imageURL) else {
return
}
self.tablecellimageview.image = UIImage(data: imagedata)
}
}
struct Item: Decodable {
let name: String
let price: Float
let image: String
}
func extracted() {
guard let url = URL(string: "http://rajeshrmohan.com/sport.json")
else {
return
}
let task = URLSession.shared.dataTask(with: url){
(data,response,error) in
guard let dataResponse = data,
error == nil else {
print(error?.localizedDescription ?? "Response Error")
return
}
do {
let decoder = JSONDecoder()
let items: [Item] = try decoder.decode([Item].self, from: dataResponse)
//print(model)
for i in 0..<items.count {
self.myData.append(items[i])
}
}
catch let parsingError {
print("Error", parsingError)
}
}
task.resume()
}
Finally, try as far as you can to avoid force casting, check this question for further insights about force casting.
Optional chaining would be helpful too.
I want to show data in UICollectionView. Which is coming from UITableView cell. My main concern is this. I am passing a key catgID from cellForRowAt in another API and getting data from it. But data is not coming proper way.

I want to show data coming in CollectionView in a proper formate. If Tableview index == 0 and Category id is coming 10 then. Category id 10 will first then one by one in a sequence I want to pass category id. In my case Category id is not coming in a queue.
Update the tableview datasource method as
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "Cell1") as! MenuTableCell
cell.lblCategoryTitle.text = arrayMenuCat[indexPath.row].category_name
cell.menuProductsAPI(categoryid: arrayMenuCat[indexPath.row].id)
return cell
}
And remove menuProductsAPI(categoryid: catgID!) from awakeFromNib method
I have a UITableView that is populated with items from a titles array and I have it setup so that when didSelectRowAt indexPath is called, a variable called arrayIndex is changed to the indexPath and the content of the next VC is changed.
So if a user taps on:
Row 0 > VC will have Title 0, Definition 0 and Link 0
Row 12 > VC will have Title 12, Definition 12 and Link 12
I have a search bar however that stores the filtered results in a searchResults array and displays them in the tableView. When a search is performed, the array index will no longer correspond, so if the search query changes the tableview to
Title 4 on Row 0 > VC will have Title 0, Definition 0 and Link 0
Title 5 on Row 1 > VC will have Title 1, Definition 1 and Link 1
Title 18 on Row 2 > VC will have Title 2, Definition 2 and Link 2
I understand why it doesn't work as expected, but I am not sure how to update my logic to fix it. Thoughts? Here is my code:
ListController:
import UIKit
var arrayIndex = 0 // is used in DefinitionController to determine which title/definition/link to show.
var isSearching = false
class ListController: UIViewController, UITableViewDataSource, UITableViewDelegate, UISearchBarDelegate {
#IBOutlet var tableView: UITableView!
#IBOutlet var searchBar: UISearchBar!
// Search Delegate
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
if searchText == "" {
isSearching = false
tableView.reloadData()
} else {
isSearching = true
searchResults = (titles.filter { $0.lowercased().contains(searchText.lowercased()) })
tableView.reloadData()
}
}
//Table Delegate
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
if isSearching == true {
// code to run if searching is true
} else {
arrayIndex = indexPath.row // assigns the value of the selected tow to arrayIndex
}
performSegue(withIdentifier: "segue", sender: self)
tableView.deselectRow(at: indexPath, animated: true)
}
// Table Data Source
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if isSearching == true {
return searchResults.count
} else {
return titles.count
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// Cell Data Source
let cell = UITableViewCell()
if isSearching == true {
cell.textLabel?.text = searchResults[indexPath.row]
} else {
cell.textLabel?.text = titles[indexPath.row]
}
// Cell Visual Formatting
cell.backgroundColor = UIColor(red:0.05, green:0.05, blue:0.07, alpha:0)
cell.textLabel?.textColor = UIColor.white
cell.textLabel?.font = UIFont(name: "Raleway", size: 18)
cell.accessoryType = UITableViewCellAccessoryType.disclosureIndicator
// if (cell.isSelected) {
// cell.backgroundColor = UIColor.cyan
// }else{
// cell.backgroundColor = UIColor.blue
// }
return cell
}
override func viewDidLoad() {
super.viewDidLoad()
self.title = "\(titles.count) Definitions"
// TextField Color Customization
let searchBarStyle = searchBar.value(forKey: "searchField") as? UITextField
searchBarStyle?.textColor = UIColor.white
searchBarStyle?.backgroundColor = UIColor(red:1.00, green:1.00, blue:1.00, alpha:0.05)
}
}
Definition Controller:
import UIKit
class DefinitionController: UIViewController {
#IBOutlet var definitionTitle: UILabel!
#IBOutlet var definitionBody: UILabel!
#IBOutlet var definitionSources: UILabel!
// Open link in Safari
#objc func tapFunction(sender:UITapGestureRecognizer) {
print("tap working")
if let url = URL(string: "\(links[arrayIndex])") {
UIApplication.shared.openURL(url)
}
}
override func viewDidLoad() {
super.viewDidLoad()
definitionTitle.text = titles[arrayIndex]
definitionBody.text = definitions[arrayIndex]
self.title = "" // Used to be \(titles[arrayIndex])
// Sources Link
let tap = UITapGestureRecognizer(target: self, action: #selector(DefinitionController.tapFunction))
definitionSources.addGestureRecognizer(tap)
}
}
Try using a dictionary where the key is your title and its value its a dictionary containing the definition and link, and an array where you will store the search results i.e the keys searched.
var dictionary = ["title 0":["definition 0", "Link 0"], "title 1": ["definition 1", "Link 1"]]
func searchBar(_ searchBar: UISearchBar, textDidChange searchText: String) {
if searchText == "" {
isSearching = false
tableView.reloadData()
} else {
isSearching = true
for (key, value) in dictionary {
if key==searchText{
resultsArray.append(key)
}
}
tableView.reloadData()
}
}
Now when you tap on a cell in the List Controller let it know which key's details you want to initialise and load in the next VC:
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let DefinitionViewController = self.storyboard?.instantiateViewController(withIdentifier: "DefinitionViewController") as! DefinitionViewController
//initialise data for the view controller
ListViewController.initDetails(forKey: resultsArray[indexPath.row])
performSegue(withIdentifier: "segue", sender: self)
tableView.deselectRow(at: indexPath, animated: true)
}
In your Definition Controller initialise the details:
func initDetails(forKey key: String) {
definitionBody.text=dictionary[key]![0]
definitionSources.text=dictionary[key]![1]
}
I thought of what seems to me like a pretty dirty solution, because it requires keeping two sets of titles, so I'm still curious if anyone knows a better way, but this does work:
If searching (to avoid calling the switch if it's not needed), under didSelectRowAt indexPath, I created a switch that essentially checks the text of the selected cell and sets the value of arrayIndex accordingly.
let selectedCell = tableView.cellForRow(at: indexPath)?.textLabel!.text ?? "Undefined"
switch selectedCell {
case "Anger": arrayIndex = 0
case "Anguish": arrayIndex = 1
case "Anxiety": arrayIndex = 2
case "Annoyance": arrayIndex = 3
case "Apathy": arrayIndex = 4
default: print("Undefined Search Query")
}
The titles array will eventually have some 55 elements and I had hoped to keep all the data in a separate Data.swift file, but this is the only solution I have so far.
Is it possible to get the data from the external database when a UItableViewCell is pressed?
I managed to create a UItableView where I am displaying the data from the database. If I press a cell then all the data that are linked to it should be displayed. For eg. if I have 4 main categories in the database such as TOOLS, OTHERS, SECURITY, PETS and each of them has its sub-catecory and are linked with each other in the database. So if I click on Pets, it should filter out and only Show me CATS, DOGS, COWS, LIONS. When I run this SQL I am able to get the information but cant figure it this out on Swift.
UItableViewCell is in my FirstviewController and its the Main Category .
When I click here it goes to my destination VC and has the table again in here.enter image description here
DestViewController is the sub-category

My first VC works fine but my second VC doesnot get the data
Thanks for your time :)
SK
To access the cell that has been pressed, you need to call the didSelectRowAtIndexPath function.
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let value = values[indexPath.row]
let vc = storyboard?.instantiateViewController(withIdentifier: "SubCatergory_ViewController") as! SubCatergory_ViewController
vc.cate_Id = value["NAME"] as! String
//self.navigationController?.pushViewController(vc, animated: true)
self.present(vc, animated: true, completion: nil)
}
First you get the value out of your values Array on the indexPark.row. Then you instantiate your second viewController.
Then you set your String value of cate_Id to the desired String value of your item value. And then you just need to present the new viewController.
If you're using a UINavigationController and you want a "back" button, then you use: self.navigationController?.pushViewController(vc, animated: true)
If you just want to present the viewController, you use self.present(vc, animated: true, completion: nil)
Comment or uncomment whatever presentation method you prefer.
so this is my first post here I've been developing in swift for a few months now and just can't work my way around this problem.
I have tried explaining what I need help with in my image.
If i click on tableview row 1 i want send an array of 30-70 images to a collection view and this kinda works, except it shows same images on all rows, tableview row 2 -3 -4.
