It's a library on iOS which is suitable for OAuth2. It supports authorization all websites which are using OAuth2 such as: smarthings, uber, fitbit, delivery, etc...


  1. https://github.com/lukeredpath/LROAuth2Client: I was developing based on this library. Basically, it covers > 80% the works. Please share and thanks him about this.

  2. https://github.com/nicklockwood/Base64: it's base64 library I'm using for this library.


  1. UI:

    • Use autolayout.
    • Use ARC.
    • Make UX better.
  2. Authorization:

    • Add initWithDict function for OAuthRequestController
    • Add Authorization key in order to avoid some website requires it.
  3. More things:

    • Fix warning and some small issues for LROAuth2Client
    • Upgrade lib to pod project for easy use.


  1. To run the example project, clone the repo, and run pod install from the Example directory first.

  2. Declare OAuthRequestController:

NSMutableDictionary *dictService = [NSMutableDictionary dictionary];
[dictService setObject:@"https://www.fitbit.com/oauth2/authorize" forKey:kOAuth_AuthorizeURL];
[dictService setObject:@"https://api.fitbit.com/oauth2/token" forKey:kOAuth_TokenURL];
[dictService setObject:@"YOUR CLIENT ID" forKey:kOAuth_ClientId];
[dictService setObject:@"YOUR SECRET KEY" forKey:kOAuth_Secret];
[dictService setObject:@"YOUR CALLBACK URL" forKey:kOAuth_Callback];
[dictService setObject:@"activity heartrate location nutrition profile settings sleep social weight" forKey:kOAuth_Scope];

OAuthRequestController *oauthController = [[OAuthRequestController alloc] initWithDict:dictService];
oauthController.view.frame = self.view.frame;
oauthController.delegate = self;
[self presentViewController:oauthController animated:YES completion:^{

  1. Implement OAuthRequestController method to obtain accesstoken:
- (void)didAuthorized:(NSDictionary *)dictResponse {
    NSLog(@"%@", dictResponse);


OAuth2 is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod "OAuth2"
