I have added Scroll View and Stack View in it, but it does not seems to be the solution. I would like to have an effect like below: One photo and 3 labels under the photo in a container. I have 12 items like this, that is why I need ScrollView. Any ideas how to make it step by step? Here is the solution (airbnb app) I would like to have (I needed to put it on imgur, because there was an error, while adding a photo here):

Hello,
I try to fetch data from my API every 5 seconds. I did this code, but it does not work. Any ideas what I'm doing wrong?
let urlString = "https://radio.app/api/nowplaying/radio_x"
let url = URL(string: urlString)!
let session = URLSession.shared
let dataTask = session.dataTask(with: url) { data, response, error in
if let error = error {
print(error)
return
}
guard let data = data else {
print("data is nil")
return
}
let decoder = JSONDecoder()
do {
let radio = try decoder.decode(RadioAPI.self, from: data)
print(radio)
DispatchQueue.main.asyncAfter(deadline: .now() + 5, execute: {
//this is the line that I've added DispatchQueue.main.asyncDispatchQueue.main.asyncAfter insted of standard
self.songtitle.text = radio.nowPlaying.song.title
self.artist.text = radio.nowPlaying.song.artist
//albumcover art section
if let artUrl = URL(string: radio.nowPlaying.song.art) {
//I need to load an image from `artUrl`
let imageDatatask = session.dataTask(with: artUrl) { imageData, imageResponse, imageError in
if let error = error {
print(error)
return
}
guard let imageData = imageData else {
print("image_data is nil")
return
}
//let albumArt = UIImage(data: imageData)
DispatchQueue.main.async {
let albumArt = UIImage(data: imageData)
let albumView = UIImageView(image: albumArt)
}
}
imageDatatask.resume()
}
})
}
catch {
print("Error Parsing JSON: \(error)")
}
}
dataTask.resume()
}
Hello,
This is the continuation of https://developer.apple.com/forums/thread/692878?login=true&page=1#692455022 where @Calude31 tried to help me. I've added two buttons for my annotationView. I have 25 annotations and I would like to have seperate button actions for each annotation. Now when I try to customize an action per annotation for rightButton switch only changes colors of the annotations NOT the rightButton.addTarget(self, action: #selector(didClickDetailDisclosure(button:)), for: .touchUpInside) - I think because od the return annotationView at the end - I need to change all three annotation parameters (color, icon, button action). Here is my code:

Hello, as discussed in my previous topic with @Claude31 (Link ) I have a problem with riding off layout. Should I register the nib somewhere and in nib put constraints for a cell? Below I'm showing What I've got so far and how it looks like on device:
I have tried many solution but nothing helped, so i just putted constraints for collection view. I dont know how to put constraints for the cell (It is greyd out), maybe in nib file?:
I have defined there class and identifier.
Here is how it looks like on device:
I would like it to look like in the first screen shot (storyboard).
Here are my files connected with collectionview vc:
First one is Controller with code, another two are connected with the cell.
Here is the ModernizmCollectionViewCell file:
import UIKit
class ModernizmCollectionViewCell: UICollectionViewCell {
@IBOutlet weak var imageCell: UIImageView!
@IBOutlet weak var navButton: UIIButton!
@IBOutlet weak var title: UILabel!
@IBOutlet weak var subTitle: UILabel!
@IBOutlet weak var locationLabel: UILabel!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
}
Many thank for your help.
Hello,
I've implemented a button which locates user on map. I would also to inform user, when location sharing for this app is set to never, that user needs to turn it on in settings. Here are those functions:
func checkLocationServices() {
if CLLocationManager.locationServicesEnabled() {
checkLocationAuthorization()
} else {
// Show alert letting the user know they have to turn this on.
}
}
func checkLocationAuthorization() {
let manager = CLLocationManager()
switch manager.authorizationStatus {
case .authorizedWhenInUse:
mapView.showsUserLocation = true
case .denied: // Show alert telling users how to turn on permissions
break
case .notDetermined:
locationManager.requestWhenInUseAuthorization()
mapView.showsUserLocation = true
case .restricted: // Show an alert letting them know what’s up
break
case .authorizedAlways:
break
@unknown default:
break
}
}
@IBAction func myLocationButtonTapped(_ sender: Any) {
mapView.showsUserLocation = true
mapView.setUserTrackingMode(.follow, animated: true)

Hello, Im trying to implement directions (navigation) from my app. All I want to do is to open map app (Google Maps or Apple Maps) with ready to go directions after user click button - in my case leftCalloutAccessoryView called leftButton. I've been trying some options, but without a good result. Here is my code:
func findPlace(_ places: [Place]) {
for place in places {
let annotations = MKPointAnnotation()
annotations.title = place.name
annotations.subtitle = place.description
annotations.coordinate = CLLocationCoordinate2D(latitude:
place.lattitude, longitude: place.longtitude)
mapView.addAnnotation(annotations)
}
}
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
guard !(annotation is MKUserLocation) else { return nil }
mapView.delegate = self
let annotationView = MKAnnotationView(annotation: annotation, reuseIdentifier: String(annotation.hash))
let identifier = "identifier"
annotationView.canShowCallout = true
guard let annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: identifier, for: annotation) as? MKMarkerAnnotationView else { return nil }
let rightButton = UIButton(type: .detailDisclosure)
rightButton.tag = annotation.hash
annotationView.canShowCallout = true
annotationView.rightCalloutAccessoryView = rightButton
let leftButton = UIButton(frame: CGRect(
origin: CGPoint.zero,
size: CGSize(width: 25, height: 25)))
leftButton.setBackgroundImage(#imageLiteral(resourceName: "nav"), for: .normal)
annotationView.leftCalloutAccessoryView = leftButton
leftButton.addTarget(self, action: #selector(didClickDetailDisclosureNavigation(button:)), for: .touchUpInside)
@objc func didClickDetailDisclosureNavigation(button: UIButton) {
let launchOptions = [MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving]
????.openInMaps(launchOptions: launchOptions)
//Here I've tried some solutions like `annotations.openInMaps(launchOptions: launchOptions)`- but it does not make sense.
}
Hello,
I've implemented directions to my annotations on map. But when Apple Maps are opening I can only see Uknown Location as a destination point. What I would like to do is to have Annotation title instead of Unknown Location. Here is my code:

var annotation: MKPointAnnotation?
}
func findPlace(_ places: [Place]) {
for place in places {
let annotations = MKPointAnnotation()
annotations.title = place.name
annotations.subtitle = place.description
annotations.coordinate = CLLocationCoordinate2D(latitude:
place.lattitude, longitude: place.longtitude)
mapView.addAnnotation(annotations)
}
}
func mapView(_ mapView: MKMapView, viewFor annotation: MKAnnotation) -> MKAnnotationView? {
guard !(annotation is MKUserLocation) else { return nil }
let identifier = "identifier"
guard let annotationView = mapView.dequeueReusableAnnotationView(withIdentifier: identifier, for: annotation) as? MKMarkerAnnotationView else { return nil }
let leftButton = AnnotationButton(frame: CGRect(
origin: CGPoint.zero,
size: CGSize(width: 25, height: 25)))
leftButton.setBackgroundImage(#imageLiteral(resourceName: "nav"), for: .normal)
annotationView.leftCalloutAccessoryView = leftButton
leftButton.addTarget(self, action: #selector(didClickDetailDisclosureNavigation(button:)), for: .touchUpInside)
if let pointAnnotation = annotation as? MKPointAnnotation {
leftButton.annotation = pointAnnotation
}
@objc func didClickDetailDisclosureNavigation(button: AnnotationButton) {
let launchOptions = [MKLaunchOptionsDirectionsModeKey: MKLaunchOptionsDirectionsModeDriving]
if let mapItem = button.annotation?.mapItem {
mapItem.openInMaps(launchOptions: launchOptions)
}
}
extension MKPointAnnotation {
var mapItem: MKMapItem {
let placemark = MKPlacemark(coordinate: self.coordinate)
return MKMapItem(placemark: placemark)
}

Hello All,
This is my first question here, so please be lenient ;)
I'm trying to add add circular (MKCircle) annotations for all of these model objects in my code instead of adding every of them with coordinations. Here is my code:
let locationManager = CLLocationManager()
struct Szczyt {
let name: String
let opis: String
let lattitude: CLLocationDegrees
let longtitude: CLLocationDegrees
var coordinate: CLLocationCoordinate2D {
.init(latitude: lattitude, longitude: longtitude)
// here Im trying to create var for this property to set it for all objects
}
}
@IBOutlet weak var mapView: MKMapView!
@IBAction func mapTypeSegmentSelected(_ sender: UISegmentedControl) {
switch sender.selectedSegmentIndex {
case 0:
mapView.mapType = .standard
case 1:
mapView.mapType = .satellite
default:
mapView.mapType = .hybrid
}
}
let circles = szczyty.map {
MKCircle(center: $0.coordinate, radius: 100)
//here I got - Cannot use instance member 'szczyty' within property initializer; property initializers run before 'self' is available
}
let szczyty = [Szczyt(name: "one", describtion: "describtion one", lattitude: 50.333061725039226, longtitude: 16.708595782487315),
Szczyt(name: "Two", describtion: "Describtion two", lattitude: 50.444874478583854, longtitude: 20.896341184611302),
Szczyt(name: "Three", describtion: "Describiton three", lattitude: 50.555134079897516, longtitude: 15.884675411850157)]
Can someone can give me a tip or advice how to solve this? Once again - Im trying to set MKCircle for all of the objects in szczyty. Thank you in advance for your help.
In the next steps I would like to detect if user is in those circles by setting 'distance(from:)' method to determinate user location between circle and user location. Than user should have an option to check in in specified area. Also if you would have any tips and advices what to use to do it, I'd be very thankful.

Hello All,
I have an app, which is playing url mp3 audio with two image buttons - play and stop. Now I would like to improve it a little bit. I have two .png images (play.png and pause.png) right now and I would like them to change with each other with a tap depending on whether the stream is on or off. Any ideas how to make it? Here is my code:
import UIKit
import AVKit
import MediaPlayer
class ViewController: UIViewController, AVAudioPlayerDelegate {
var player : AVPlayer!
var dict = NSDictionary()
@IBAction func playButtonPressed(_ sender: UIButton){
let url = "https://stream.com/radio.mp3"
do {
try AVAudioSession.sharedInstance().setCategory(.playback, mode: .default, options: [.mixWithOthers, .allowAirPlay])
try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback, options: [])
print("Playback OK")
try AVAudioSession.sharedInstance().setActive(true)
print("Session is Active")
} catch {
print(error)
}
player = AVPlayer(url: URL(string: url)!)
player.volume = 1.0
player.rate = 1.0
player.play()
}
@IBAction func stopButtonStopped(sender: UIButton) {
player.pause()
}
Hello,
First of all, I dont know if I'm asking for too much.
I'm new in parsing API data in Swift. What I'm trying to do is to show in my two labels and UIImageView (or maybe there is other way to show album cover from external url) data from nowplaying api on my internet radio station.
Here how it is gonna look like in Main.storyboard:
So far I've tried couple of solutions, but I've stuck on parsing step. Here is my code:
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
overrideUserInterfaceStyle = .light
setupRemoteCommandCenter()
//Radio API endpoint
let urlString = "https://admin.radiopromil.online/api/nowplaying_static/radio_promil.json"
let url = URL(string: urlString)
guard url != nil else {
return
}
let session = URLSession.shared
let dataTask = session.dataTask(with: url!) { (data, response, error) in
if error == nil && data != nil {
let decoder = JSONDecoder()
do {
let radio = try decoder.decode(radioAPI.self, from: data!)
print(radio)
DispatchQueue.main.async {
self.title.text = ????
self.artist.text = ????
}
}
catch {
print("Error Parsing JSON")
}
}
}
dataTask.resume()
}
}
So far I removed everything from radioAPI.swift. I
've got two API endpoint:
This one is static JSON https://admin.radiopromil.online/api/nowplaying_static/radio_promil.json
This one is standard API: https://admin.radiopromil.online/api/nowplaying/radio_promil
To sum up: I would like to parse data from API (now_playing: artist, title and cover art url) into two labels and UIImageView.
Data in API is changing when next song is playing.
Thank you in advance for your help.
Hello,
I've implemented two functions in View controller (setupRemoteTransportControls() and setupNowPlaying()) and added one function to AppDelegate, but I'm still unable to see background audio controls of my app on the lock screen and also audio interruption function isn't working. This is the live stream from url, as you can spot on in the code. In the general settings I have added background playing:
What I would like to do is to print on the Remote Command Center artist, title and albumArt, but but i was stuck just displaying the command center. I attach link my code on github, because it is too many characters to paste it: https://github.com/pawelzet/promil_new/blob/main/ViewController.swift
Here is AppDelegate func that I've added:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
application.beginReceivingRemoteControlEvents()
// Override point for customization after application launch.
return true

Hello,
I would like to store, save users data inside the app (Best option to store it in the cloud) with location the user reach. The loaction check in point on the map is within radius 100 meters. So the thing I would like to do is to show as a list in the second viewcontroller Zdobyte Szczyty, names of the locations sczyt.name from the first ViewController (the one with the map) that user reached (clicked with a button to check in).

Hello,
I'm learning swift now, so this is my second question here :) I'm creating the app with some annotations on the map. I've added MKCircles in radius 200m from the annotation. This should be a radius in which user can check-in and save his loacation. Can I use distance(from:)to do it?
In general I'm looking for some tips/advices how to set this check in (Could be check-in button inside the annotation view) that saves user location if user is in radius 200m from the annotation. The check-in should be connected to the name and describtion of the annotation (sczyt.name and szczyt.opis), and the annotation name should be saved in a table view "Zdobyte Szczyty", which is another tab bar view in the app. My mainstoryboard looks like this:
There is a Map controller and Zdobyte Szczyty controller. so I would like to save location only if in radius 200m from annotation as annotation name (szczyt.name) and describtion (szczyt.opis) in table view, which is based in Zdobyte Szczyty viewcontroller.

Here is my ZdobyteSzczyty view controller:
import UIKit
import SwiftUI
class Zdobyte_ViewController: UIViewController {
struct ContentView: View {
var body: some View {
Text("Test viewcontroller gór") //this is not working
}
}
override func viewDidLoad() {
super.viewDidLoad()
}
}
I'm parsing some data from my API and I would like to show artist and title in title section of MPMediaItemPropertyTitle and the album art. Right now I can print a string, as you can spot in the code below, but I would like to print the API data, as I'm doing it in the labels. Thank you in advance for your help. Here is my code:
import UIKit
import AVKit
import MediaPlayer
class ViewController: UIViewController, AVAudioPlayerDelegate {
var player : AVPlayer!
var dict = NSDictionary()
@IBOutlet weak var artist: UILabel!
@IBOutlet weak var songtitle: UILabel!
@IBOutlet weak var artUrl: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
overrideUserInterfaceStyle = .light
setupRemoteTransportControls()
requestNowPlaying()
setupNowPlaying()
addInterruptionsObserver()
}
[...]
//There is parsing section [...]
DispatchQueue.main.async {
self.songtitle.text = radio.nowPlaying.song.title
self.artist.text = radio.nowPlaying.song.artist
self.playlist.text = radio.nowPlaying.playlist
//albumcover art section
if let artUrl = URL(string: radio.nowPlaying.song.art),
artUrl != self.songArtUrl {
//Loading image from `artUrl`
let imageDatatask = session.dataTask(with: artUrl) { imageData, imageResponse, imageError in
if let imageError = imageError {
print(imageError)
return
}
guard let imageData = imageData else {
print("image_data is nil")
return
}
DispatchQueue.main.async {
self.songArtUrl = artUrl
let albumArt = UIImage(data: imageData)
self.artUrl.image = albumArt
}
}
imageDatatask.resume()
}
[...]
//here is some code with adding remote controls
[...]
func setupNowPlaying() {
// Define Now Playing Info
var nowPlayingInfo = [String : Any]()
nowPlayingInfo[MPMediaItemPropertyTitle] = "Here I would like to print artist + title"
nowPlayingInfo[MPMediaItemPropertyArtist] = "My name as string - nothing to change"
if let image = UIImage(named: "Deault_albumart") { //Here I would like to add image from API
nowPlayingInfo[MPMediaItemPropertyArtwork] = MPMediaItemArtwork(boundsSize: image.size) { size in
return image
}
}
nowPlayingInfo[MPNowPlayingInfoPropertyIsLiveStream] = true
MPNowPlayingInfoCenter.default().nowPlayingInfo = nowPlayingInfo
}
