How Can I Change a String Using Remote Config? - swift

Question

I'm creating an app that plays a sound when a button is clicked. It consists of UIButton to play the sound, UIImageView to display the associated image, and another UIButton which I'm using like a label to describe the button. I want to be able to configure all three parameters so I can change them remotely from Firebase. So far I figured out how to change the label, but I want to be able to change the URL that the sound and image load from. Here is my code:
import UIKit
import Firebase
import AVKit
class FirebaseViewController: UIViewController, AVAudioPlayerDelegate {
//These variables are for my sound when I click a button
var firesound1 = AVPlayer()
var firesound2 = AVPlayer()
var firesound3 = AVPlayer()
//These outlets reference the labels(UIButton) and UIImageView in the storyboard
#IBOutlet weak var firelabel1: UIButton!
#IBOutlet weak var firelabel2: UIButton!
#IBOutlet weak var firelabel3: UIButton!
#IBOutlet weak var fireimage1: UIImageView!
#IBOutlet weak var fireimage2: UIImageView!
#IBOutlet weak var fireimage3: UIImageView!
func updateViewWithRCValues() {
//These remote config options allow me to change the text of the UIButton, which here I'm using like a UILabel
firelabel1.setTitle(buttonLabel1, for: .normal)
let buttonLabel2 = RemoteConfig.remoteConfig().configValue(forKey: "label2").stringValue ?? ""
firelabel2.setTitle(buttonLabel2, for: .normal)
let buttonLabel3 = RemoteConfig.remoteConfig().configValue(forKey: "label3").stringValue ?? ""
firelabel3.setTitle(buttonLabel3, for: .normal)
let url = RemoteConfig.remoteConfig().configValue(forKey: "url1").stringValue ?? ""
firelabel3.setTitle(buttonLabel3, for: .normal)
}
func setupRemoteConfigDefaults() {
let defaultValues = [
"label1": "" as NSObject,
"label2": "" as NSObject,
"label3": "" as NSObject
]
RemoteConfig.remoteConfig().setDefaults(defaultValues)
}
func fetchRemoteConfig() {
// Remove this before production!!
let debugSettings = RemoteConfigSettings(developerModeEnabled: true)
RemoteConfig.remoteConfig().configSettings = debugSettings!
RemoteConfig.remoteConfig().fetch(withExpirationDuration: 0) { [unowned self] (status, error) in guard error == nil else {
print ("Error fetching remote values: \(String(describing: error))")
return
}
print("Retrieved values from the cloud")
RemoteConfig.remoteConfig().activateFetched()
self.updateViewWithRCValues()
}
}
override func viewDidLoad() {
super.viewDidLoad()
setupRemoteConfigDefaults()
fetchRemoteConfig()
//This code loads an image from a url into a UIImageView. I want to be able to configure the url like a parameter so I can change the url from the firebase website.
let url = URL(string: "https://ichef-1.bbci.co.uk/news/976/media/images/83351000/jpg/_83351965_explorer273lincolnshirewoldssouthpicturebynicholassilkstone.jpg")
let task = URLSession.shared.dataTask(with: url!) { (data, response, error) in
if (error != nil)
{
print("ERROR")
}
else
{
var documentsDirectory: String?
var paths = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true)
if paths.count > 0
{
documentsDirectory = paths [0]
let savePath = documentsDirectory! + "/ImageOne"
FileManager.default.createFile(atPath: savePath, contents: data, attributes: nil)
DispatchQueue.main.async
{
self.fireimage1.image = UIImage(named: savePath)
}
}
}
}
task.resume()
}
//This code plays the sounds. I also want to be able to configure the url like a parameter.
#IBAction func soundpressed1(_ sender: Any) {
let sound1 = AVPlayerItem(url: URL(string: "https://firebasestorage.googleapis.com/v0/b/mlg-soundboard-2018-edition.appspot.com/o/hitmarker.mp3?alt=media&token=e5d342d6-4074-4c50-ad9d-f1e41662d9e9")!)
firesound1 = AVPlayer(playerItem: sound1)
firesound1.play()
}
override func didReceiveMemoryWarning() {
}
}
Basically I want to be able to swap out the URLs with Remote Config.

You can either create separate keys in Remote config for Text, Sound URL and Image URL.
Or you can create a key called button_config and supply all the three params in a JSON
button_config = {"text" : "My button label", "sound_url" : "https://foo.com/sound.mp3", "image_url" : "https://foo.com/image.png"}
