OAuthReactiveSwift is a powerful and flexible library for implementing OAuth authorization flows in Swift. It seamlessly integrates with ReactiveSwift, allowing you to handle OAuth authentication requests and responses in a reactive and efficient manner.

Installation

To install OAuthReactiveSwift, simply add the following line to your Podfile:

pod 'OAuthReactiveSwift'

Then run the following command:

pod install

Usage

Authorization Flow

OAuthReactiveSwift provides convenient methods to initiate and handle the OAuth authorization flow. Follow the steps below:

1. Create an instance of OAuthAuthorization with your OAuth client information:

let oauth = OAuthAuthorization(
    clientID: "YOUR_CLIENT_ID",
    clientSecret: "YOUR_CLIENT_SECRET",
    redirectURL: URL(string: "YOUR_REDIRECT_URL")!,
    scope: "YOUR_SCOPES")

2. Call the authorize method to open the authorization URL:

oauth.authorize { [weak self] result in
    // Handle authorization completion
}

3. Implement the URL scheme delegate method in your AppDelegate to handle the redirect URL:

func application(_ app: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:]) -> Bool {
    oauth.handleRedirect(url)
    return true
}

4. In the completion block of the authorize method, you can verify whether the authorization was successful:

switch result {
    case .success(let token):
        // Authorization was successful, use the token for further API calls
    case .failure(let error):
        // Authorization failed, handle the error
}

Token Refresh

To refresh an expired token, you can use the refreshToken method on the OAuthAuthorization instance:

oauth.refreshToken { result in
    // Handle token refresh completion
}

Revoking Access

If you need to revoke access, you can use the revokeAccess method:

oauth.revokeAccess { result in
    // Handle access revocation completion
}

Example

Here’s a simple example of using OAuthReactiveSwift to implement an OAuth authorization flow:

import OAuthReactiveSwift

class MyViewModel {
    private let oauth: OAuthAuthorization
    
    init() {
        oauth = OAuthAuthorization(
            clientID: "YOUR_CLIENT_ID",
            clientSecret: "YOUR_CLIENT_SECRET",
            redirectURL: URL(string: "YOUR_REDIRECT_URL")!,
            scope: "YOUR_SCOPES"
        )
    }
    
    func authorize() {
        oauth.authorize { [weak self] result in
            switch result {
            case .success(let token):
                // Authorization was successful, use the token for further API calls
                
            case .failure(let error):
                // Authorization failed, handle the error
            }
        }
    }
}
