Ich habe 5 Klassen erstellt, die ProfileHomeModel, ProfileLocationModel, ProfileRequestManager, ProfileTableUserViewController und ProfileTableViewCell enthält. Mein Ziel ist es, Json korrekt zu parsen und die Daten anzuzeigen. Ich bin auf ein Problem in meiner Anfrage-Manager-Klasse gestoßen. Ich bin neu zu schnell. Ich möchte dies tun, ohne swiftyJSON und Alamofire zu verwenden.So erstellen Sie RequestManager-Klasse ohne Verwendung von Frameworks Swift
import Foundation
class ProfileRequestManager{
let urlPath = "*********"
let url = NSURL(string: urlPath)
let data = NSData(contentsOfURL: url!)
do {
let jsonData = try NSJSONSerialization.JSONObjectWithData(data!, options: .AllowFragments) as? NSDictionary
print(jsonData)
let results = jsonData!.objectForKey("strengths") as? [NSDictionary] ?? []
for result in results {
print(result)
}
}
catch {
print("Something went wrong while parsing json data fetched from the API")
}
}
jsonData
{ "success": true, "profile": { "firstname": "Vignesh", "lastname": "Krish", "title": "Software Developer Intern", "designations": null, "specialty": "Computer Science", "location": "0", "email": "[email protected]", "phone": "4026136265", "biography": "Boxing and Travelling", "interests": "Watching movies", "skills": "Hozier and A.R Rahman", "goals": "becoming a software developer", "mentors": "Hardik Patel", "doh": "2016-05-09", "dob": "1994-06-08", "strengths": [ { "id": "4", "name": "Analytical", "description": "People exceptionally talented in the Analytical theme search for reasons and causes. They have the ability to think about all the factors that might affect a situation.", "color": "9c0000" }, { "id": "17", "name": "Focus", "description": "People exceptionally talented in the Focus theme can take a direction, follow through, and make the corrections necessary to stay on track.

Ich versuche, über
alles davon zurückzukehren der Fehler Ich bin auf der fangen bekommen. Xcode
gibt mir einen erwarteten Deklarationsfehler. Ich habe meine geschweiften Klammern überprüft.
Ich würde einige Hilfe schätzen, um dies herauszufinden.
Auch ich brauche keine URL für Sicherheitszwecke. Ich hoffe, es hilft.
Ich versuche auch, alle Werte in separaten Zellen anzuzeigen. Das habe ich jetzt.
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
if indexPath.row == 0 {
let cell = tableView.dequeueReusableCellWithIdentifier("ProfileCell", forIndexPath: indexPath) as! ProfileUserTableViewCell
cell.firstName?.text = firstName
cell.lastName?.text = lastName
cell.title?.text = title
return cell
}
}
Wissen Sie, wie ich das beheben kann?
Dies ist meine aktuelle Situation. Ich kann es nicht in Tabellenansichtszellen anzeigen lassen. Das Problem scheint damit zu sein, wie ich meine json-Werte den Etiketten zuweise.

vielen dank bro !! Ich habe jedoch eine andere Frage. Ich versuche, die JSON-Werte auf meinem ui anzuzeigen. Ich habe den Code und die Frage an den Hauptpost angehängt. Könntest du mir bitte helfen? –
Wie möchten Sie die Daten in Ihrer Benutzeroberfläche anzeigen? Tabellenansicht ? – amagain
Darüber hinaus ist dies nicht der genaue Ansatz, den Sie Codes schreiben. Dieser Code dient nur dem Zweck, etwas zu tun. Bitte studieren Sie das Designmuster und versuchen Sie, dem MVC-Muster zu folgen, da dies über alle Bereiche hinweg verfolgt wird. – amagain
