    No problem, that would look like this:

     

    [DropboxClientsManager setupWithAppKey:@"APP_KEY"];

DBTransportClient *transportClient = [[DBTransportClient alloc] initWithAccessToken:nil
                                                                         selectUser:nil
                                                                          baseHosts:nil
                                                                          userAgent:nil
                                                                backgroundSessionId:nil

                                                                             appKey:@"APP_KEY"
                                                                          appSecret:@"APP_SECRET"];
[DropboxClientsManager authorizedClient:[[DropboxClient alloc] initWithTransportClient:transportClient]];
    [[DropboxClientsManager.authorizedClient.authRoutes tokenFromOauth1:@"OAUTH1_TOKEN_KEY" oauth1TokenSecret:@"OAUTH1_TOKEN_SECRET"] response:^(DBAUTHTokenFromOAuth1Result *result, DBAUTHTokenFromOAuth1Error *routeError, DBRequestError *error) {

    In the latest version of the SDK, the equivalent code would be:

     

    DBTransportDefaultConfig *transportClient = [[DBTransportDefaultConfig alloc] initWithAppKey:@"APP_KEY" appSecret:@"APP_SECRET"];

[DBClientsManager setupWithTransportConfig:transportClient];
    [[DBClientsManager.authorizedClient.authRoutes tokenFromOauth1:@"OAUTH1_TOKEN_KEY" oauth1TokenSecret:@"OAUTH1_TOKEN_SECRET"] setResponseBlock:^(DBAUTHTokenFromOAuth1Result *response, DBAUTHTokenFromOAuth1Error *routeError, DBRequestError * error) {
    if (response) {
        NSLog(@"OAuth 2 access token: %@\n", response.oauth2Token);
    } else {
        NSLog(@"%@\n%@\n", routeError, error);
    }
}];

     

    If you are migrating from an old official SDK though, we recently added a helper that can automatically migrate those stored tokens:

      Thanks Greg, that last link helps a lot.

       

      BTW, there's a typo in Migrating OAuth tokens from earlier SDKs, in the unsuccessfullyMigratedTokenData code. The format either has an extra %@ at the start or there is a missing argument.

            NSLog(@"%@DropboxUserID: %@, AccessToken: %@, AccessTokenSecret: %@, StoredAppKey: %@", tokenData[0],

        Thanks for letting us know, Steve. This should be updated now!
