json data staying after changing son address. iOS, Swift - ios

Question

I am getting json data and parsing it, but for some reason when I change the address to different json and recall the function, (Im changing one eliment in album search), I get the same data in the json. I am thinking it is cached.
Here is my Address:
var SEARCH_RESULTS_ADDRESS = "\(BASE_URL)\(choiceSearch!).search&\(choiceSearch!)=\(albumSearch)&api_key=\(API_KEY)&format=json"
Here is my AddressDataService function.
func getAlbumData(completion: #escaping (_ finished: Bool) -> ()) {
guard let url = URL(string: SEARCH_RESULTS_ADDRESS) else { return }
URLSession.shared.dataTask(with: url) { (data, response, err) in
guard let data = data else { return }
do {
let decoder = JSONDecoder()
let albumDataFull = try decoder.decode(Root.self, from: data)
albumInfo = []
for business in albumDataFull.results.albummatches.album {
let artist = business.artist!
let name = business.name!
let imgUrl = business.image
let albumInd = ["name":name, "artist":artist, "url":url, "imgUrl":imgUrl] as [String : Any]
albumInfo.append(albumInd)
print("Tony: \(albumInfo.count)")
}
completion(true)
}catch let jsonErr {
print("Error seroalizing json", jsonErr)
}
}.resume()
}
Here is my relead data and address change.
func getData(completion: #escaping (_ finished: Bool) -> ()) {
AlbumDataService().getAlbumData(completion: { (complete) in
completion(true)
})
}
func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
albumSearch = searchBar.text
albumInfo = []
getData(completion: { (complete) in
DispatchQueue.main.async {
SEARCH_RESULTS_ADDRESS = "\(BASE_URL)\(choiceSearch!).search&\(choiceSearch!)=\(albumSearch!)&api_key=\(API_KEY)&format=json"
print(SEARCH_RESULTS_ADDRESS)
self.tableView.reloadData()
print("Tony Finishedediting \(albumSearch!)")
}
})
}

Answer 1

You need to set SEARCH_RESULTS_ADDRESS before it is used.
func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
albumSearch = searchBar.text
albumInfo = []
//###
SEARCH_RESULTS_ADDRESS = "\(BASE_URL)\(choiceSearch!).search&\(choiceSearch!)=\(albumSearch!)&api_key=\(API_KEY)&format=json"
print(SEARCH_RESULTS_ADDRESS)
getData(completion: { (complete) in
DispatchQueue.main.async {
self.tableView.reloadData()
print("Tony Finishedediting \(albumSearch!)")
}
})
}
(Better make it a parameter than declaring a constant-like property.)
(ADDITION)
how I would make the address a param?
Assuming you can modify the methods of AddressDataService:
func getAlbumData(_ urlString: String, completion: #escaping (_ finished: Bool) -> ()) {
print(urlString)
guard let url = URL(string: urlString) else {
print("ursString is invalid")
return
}
//...
}
And you can use it as:
func getData(_ urlString: String, completion: #escaping (_ finished: Bool) -> ()) {
AlbumDataService().getAlbumData(urlString) { complete in
completion(true)
}
}
func searchBarSearchButtonClicked(_ searchBar: UISearchBar) {
albumSearch = searchBar.text
albumInfo = []
let searchResultsAddress = "\(BASE_URL)\(choiceSearch!).search&\(choiceSearch!)=\(albumSearch!)&api_key=\(API_KEY)&format=json"
getData(searchResultsAddress) { complete in
DispatchQueue.main.async {
self.tableView.reloadData()
print("Tony Finishedediting \(albumSearch!)")
}
}
}
