将OAuth2添加到iOS项目

import UIKit
import OAuth2Client

class ViewController: UIViewController {

    var clientID = "your-client-id"
    var clientSecret = "your-client-secret"
    var redirectURI = "your-redirect-uri"
    var tokenURL = "https://your-token-url"

    override func viewDidLoad() {
        super.viewDidLoad()

        let client = OAuth2Client(clientID: clientID, clientSecret: clientSecret)

        guard let url = URL(string: tokenURL) else {
            print("Error: Could not create URL")
            return
        }

        let request = OAuth2AuthorizationRequest(
            authorizationURL: url,
            redirectURI: redirectURI,
            scope: "your-scope"
        )

        client.authorize(request: request) { (response, error) in
            if let error = error {
                print("Error: \(error.localizedDescription)")
            } else {
                print("Access token: \(response.accessToken)")
                // Use the access token to make API calls
            }
        }
    }
