I have UITableViewController with files from document folder. I name the cells by artist name. I have three artist and four songs. UITableViewCell shows two cells with the same artist. How can I fix it?
This code export data from document folder
var mp3Files: Array<String!>!
func exportData() {
var generalURL: [AnyObject]?
var arrayFiles: Array<NSURL!>!
var directory = fileManager.URLsForDirectory(NSSearchPathDirectory.DocumentDirectory, inDomains: NSSearchPathDomainMask.UserDomainMask)
var urlFromDirectory = directory.first as! NSURL
var file = fileManager.contentsOfDirectoryAtURL(urlFromDirectory, includingPropertiesForKeys: nil, options: NSDirectoryEnumerationOptions.SkipsHiddenFiles, error: nil)!
println("file \(file)")
mp3Files = file.map(){ $0.lastPathComponent }.filter(){ $0.pathExtension == "mp3" }
println("mp3 files \(mp3Files)")
}
and code fill the UITableViewCell
var cellStrings: String!
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! UITableViewCell
var dataForCell = mp3Files[indexPath.row]
var generalURL: NSURL!
var documentFolder = fileManager.URLsForDirectory(NSSearchPathDirectory.DocumentDirectory, inDomains: NSSearchPathDomainMask.UserDomainMask)
if var urlFromFolder: NSURL = documentFolder.first as? NSURL {
generalURL = urlFromFolder.URLByAppendingPathComponent(dataForCell)
println("general \(generalURL)")
}
var player = AVPlayerItem(URL: generalURL)
var metaData = player.asset.commonMetadata as! [AVMetadataItem]
for item in metaData {
if item.commonKey == "artist" {
nameArtist = item.stringValue
}
}
cell.textLabel?.text = nameArtist
//
cellStrings = cell.textLabel?.text
println("cell strings \(cellStrings)")
// Configure the cell...
return cell
}
var superArray = [String]()
var filterArray = [String]()
func filter() {

I have a tableview loading data from firebase database. When i open my app the data does not populate. it crashes and throws the error index out of range. I am fairly new to xcode and would appreciate the help. i have been given recommendations on how to fix my code with regards to having multiple arrays but everyone that advices forget i'm new and does realize that i am pulling imageurls into my tableview too and dont know how to adopt their recommendations into my code. if i could get help getting passed this error that would be awesome.
import UIKit
import FirebaseAuth

At the moment reloadData is called the image array is empty and causes the crash
Use a custom struct and reload the table view after the image data has been received
struct Event {
let title, timestamp, location : String
var image : UIImage?
}
var events = [Event]()
...
eventsDatabaseHandle = eventsRef?.child("Church Events").observe(.childAdded, with: { (snaphot) in
let eventPost = snaphot.value as! [String: Any]
let event = Event(title: eventPost["eventtitle"] as! String,
timestamp: eventPost["eventdate"] as! String,
location: eventPost["eventlocation"] as! String,
image: nil)
let task = URLSession.shared.dataTask(with: URL(string: eventPost["ImageUrl"] as! String)!) { data, _, error in
if let error = error {
print(error)
} else {
event.image = UIImage(data: data!)
DispatchQueue.main.async {
self.events.append(event)
self.tableView.reloadData()
}
}
}
task.resume()
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

I have a tableview loading data from firebase database. When I open my app the data does not populate. when I create a new post I can see the tableview cells modifying like changed were made but the post doesn't populate. I can't figure it out.

So the code below is not tested as I don't have firebase setup currently.
However, observing childAdded... the documentation says it will pass all of the current records in the database at first and will then just post new additions. So all you need to do is loop through them, setup your tableView data source and reload the table.
Rather than use multiple arrays for values I've created an array of ChurchEvent objects instead.
struct ChurchEvents {
let title: String
let location: String?
let date: Date?
let imageUrlString: String?
init(dict: [String: Any]) {
self.title = dict["title"] as String
self.location = dict["location"] as? String
// etc
}
}
var events = [ChurchEvents]()
eventsDatabaseHandle = eventsRef?.child("Church Events").observe(.childAdded, with: { snapshot in
let list = snapshot.value as? [[String : AnyObject]]
let newEvents = list.map { ChurchEvent(dict: $0) }
events.append(newEvents)
tableView.reloadData()
}
Other improvements you could make:
class EventsTableViewCell: UICollectionViewCell {
func configure(with event: ChurchEvent {
eventDate.text = event.date
eventTitle.text = event.title
eventLocation.text = event.location
// etc
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "events") as! EventsTableViewCell
let event = events[indexPath.row]
cell.configure(with: event)
return cell
}
I am following this tutorial for expanding and collapsing my table view section. As this demo is done in swift 2.2 I have made all the changes according to swift 3.0 . I am stuck at the below function at if condition(currentSectionCells[row]["isVisible"]) which gives me error as "Type 'NSFastEnumerationIterator.Element' (aka 'Any' has no subscript members)'".
func getIndicesOfVisibleRows() {
visibleRowsPerSection.removeAll()
for currentSectionCells in cellDescriptors {
var visibleRows = [Int]()
for row in 0...((currentSectionCells as! [[String: AnyObject]]).count - 1) {
if currentSectionCells[row]["isVisible"] as! Bool == true {
visibleRows.append(row)
}
}
visibleRowsPerSection.append(visibleRows)
}
}
I have tried type casting it as below
func getIndicesOfVisibleRows() {
visibleRowsPerSection.removeAll()
for currentSectionCells in cellDescriptors {
var visibleRows = [Int]()
for row in 0...((((currentSectionCells) as? NSMutableArray)?.count)! - 1) {
let temp = [currentSectionCells][row] as? NSMutableDictionary
let temp2 = temp?["isVisible"] as! Bool
if temp2 == true {
visibleRows.append(row)
}
}
visibleRowsPerSection.append(visibleRows)
}
}
But this gives me a crash at runtime on this line "let temp2 = temp?["isVisible"] as! Bool"
Crash says "EXC_BAD_INSTRUCTION" and the temp shows as nil.
Please help guys. TIA

Thank You for helping me out, I was stuck at a point where the sections weren't expanding even after your help, so just made some changes in the syntax as Swift 3.0 is very specific about type casting hence the didSelectRowAt wasn't functioning properly. Here is the complete didSelectRowAt method. Happy coding.
public func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath){
let indexOfTappedRow = visibleRowsPerSection[indexPath.section][indexPath.row]
if (cellDescriptors[indexPath.section] as! [[String: AnyObject]])[indexOfTappedRow] ["isExpandable"] as! Bool == true {
var shouldExpandAndShowSubRows = false
if (cellDescriptors[indexPath.section] as! [[String: AnyObject]])[indexOfTappedRow]["isExpanded"] as! Bool == false {
// In this case the cell should expand.
shouldExpandAndShowSubRows = true
}
((cellDescriptors[indexPath.section] as! NSMutableArray)[indexOfTappedRow] as AnyObject).setValue(shouldExpandAndShowSubRows, forKey: "isExpanded")
for i in (indexOfTappedRow + 1)...(indexOfTappedRow + ((cellDescriptors[indexPath.section] as! [[String: AnyObject]])[indexOfTappedRow]["additionalRows"] as! Int)) {
((cellDescriptors[indexPath.section] as! NSMutableArray)[i] as AnyObject).setValue(shouldExpandAndShowSubRows, forKey: "isVisible")
}
}
Swift 3/4 without use of NSMutable arrays based on the tutorial and all the code wrapped in a model.
class CellsDescriptorModel {
private var cellDescriptors: [[[String:Any]]]!

Good day! I'm building an app that needs to construct a sentence from the data from Core Data. I have this:
var players = Array<AnyObject> = []
#IBOutlet weak var sentenceLabel: UILabel!
override func viewDidLoad() {
super.viewDidLoad()
let appDelegate: AppDelegate = UIApplication.sharedApplication().delegate as! AppDelegate
let context: NSManagedObjectContext = appDelegate.managedObjectContext!
let freq = NSFetchRequest(entityName: "Orders")
players = context.executeFetchRequest(freq, error: nil)!
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return players.count
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell = tableView.dequeueReusableCellWithIdentifier("checkCell") as! SummaryCustomCell!
if cell == nil {
cell = SummaryCustomCell(style: UITableViewCellStyle.Default, reuseIdentifier: "checkCell")
}
var data: NSManagedObject = players[indexPath.row] as! NSManagedObject
cell.playerNameLabel.text = data.valueForKey("playerName") as? String
cell.teamLabel.text = data.valueForKey("team") as? String
cell.yearsLabel.text = data.valueForKey("yearsOfPlaying") as? String
for var i = 0; i < players.count;i++ {
var dataLooped: NSManagedObject = myOrders[i] as! NSManagedObject
var playerName = dataLooped.valueForKey("playerName") as? String
var team = dataLooped.valueForKey("team") as? String
var years = dataLooped.valueForKey("yearsOfPlaying") as? String
var constructedSentence: NSString = NSString(format: "%# was playing for %# for %# years.", playerName, team, years)
sentenceLabel.text = constructedSentence as! String
}
}
return cell
}
Then it gives only the last row in the database. It must loop the sentence in a single string. For example. "Kobe Bryant was playing for LA Lakers for 5 years; Lebron James was playing for Cavs for 3 years." and so on..
How can I implement this? Thank you very much!
This question already has an answer here:
UITableViewCell shows incorrect results from document folder
(1 answer)
Closed 7 years ago.
I have several UITableViewControllers and they have data from document folder into iOS Device. I export names of artists from mp3 files with help AVMetaDataItem. I get several names and I have duplicates. How can I remove duplicates from UITableViewCell?
var cellStrings: String!
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! UITableViewCell
var dataForCell = mp3Files[indexPath.row]
var generalURL: NSURL!
var documentFolder = fileManager.URLsForDirectory(NSSearchPathDirectory.DocumentDirectory, inDomains: NSSearchPathDomainMask.UserDomainMask)
if var urlFromFolder: NSURL = documentFolder.first as? NSURL {
generalURL = urlFromFolder.URLByAppendingPathComponent(dataForCell)
println("general \(generalURL)")
}
var player = AVPlayerItem(URL: generalURL)
var metaData = player.asset.commonMetadata as! [AVMetadataItem]
for item in metaData {
if item.commonKey == "artist" {
nameArtist = item.stringValue
}
}
cell.textLabel?.text = nameArtist
return cell
}
I solved my problem
var superArray = [String]()
var filterArray = [String]()
func filter() {
var proString: String!
for proItem in mp3Files {
var proFolder = fileManager.URLsForDirectory(NSSearchPathDirectory.DocumentDirectory, inDomains: NSSearchPathDomainMask.UserDomainMask)
var americaURL: NSURL!
if var proURL: NSURL = proFolder.first as? NSURL {
americaURL = proURL.URLByAppendingPathComponent(proItem)
}
var proPlayerItem = AVPlayerItem(URL: americaURL)
var proData = proPlayerItem.asset.commonMetadata as! [AVMetadataItem]
for proFiles in proData {
if proFiles.commonKey == "artist" {
superArray.append(proFiles.stringValue)
}
}
}
filterArray = Array(Set(superArray))
filterArray.sort(){ $0 < $1 }
}
