Good afternoon, I'm using the Spotify API, I try to access this Json:
I was able to successfully access the "name" value, but I would like to access the "images" array and its "url" value, so, specifically, my question would be, how to access "images" and get the value "url" "?
{

And this is the code I'm using in iOS Swift 3:
let url = "https://api.spotify.com/v1/artists?ids=6XyY86QOPPrYVGvF9ch6wz,74XFHRwlV6OrjEM0A2NCMF,12Chz98pHFMPJEknJQMWvI,6IdtcAwaNVAggwd6sCKgTI,2af5rOpTISbX2YSVYiqoFJ,0yNSzH5nZmHzeE2xn6Xshb,1GImnM7WYVp95431ypofy9,2F9pvj94b52wGKs0OqiNi2,27Owkm4TGlMqb0BqaEt3PW,7oPftvlwr6VrsViSDV7fJY"
var gruposObtenidos: NSMutableArray = []
@IBOutlet var gruposTabNormal: UICollectionView!
override func viewDidLoad() {
super.viewDidLoad()
if WebServiceController.conexionInternet(){
WebServiceController.sharedInstance.callUrlWithCompletion(url: url, params: nil, completion: { (finished, response) in
if finished{
//print(response)
//Para nombre de los grupos
let resultadoJson = NSMutableArray(array: response["artists"] as! NSArray)
self.gruposObtenidos = resultadoJson
self.gruposTabNormal.reloadData()
}else{
print("Sin conexión con el servidor")
}
}, method: .get)
}else{
print("No hay internet")
}
}
This is my controller of the UICollectionView cell:
class CancionesNormalesCollectionViewCell: UICollectionViewCell {
@IBOutlet weak var imgGrupo: UIImageView!
@IBOutlet weak var txtNombreGrupo: UILabel!
var grupos: Dictionary<String, AnyObject>!
func iniciarCelda(){
let nombreGrupo = self.grupos["name"] as! String
self.txtNombreGrupo.text = nombreGrupo
}
}
