Are you using the official API v2 Objective-C SDK? 

 

If so, you can construct a DBUserClient on the fly using an existing access token using the DBUserClient.initWithAccessToken constructor. If you want to have the SDK store the access token for you, you can use DBOAuthManager.storeAccessToken. 

 

Note that access tokens are sensitive, as they enable access to the account, so make sure you transport the access token securely. That being the case, it may just be easier/safer to process the app authorization flow again on the other device. Also, note that it isn't reccomended to distribute an app with an access token for a particular account embedded in the app, as that can be extracted by a malicious user.

      It sounds like you're using the iOS Core SDK, for Dropbox API v1. Dropbox API v1 is deprecated and being retired in a few months.

       

      You should migrate to API v2 whenever you can. I recommend using the official API v2 Objective-C SDK.

       

      This is technically possible with the iOS Core SDK as well though. You can store an existing access token using DBSession.updateAccessToken:

       

      - (void)updateAccessToken:(NSString *)token accessTokenSecret:(NSString *)secret forUserId:(NSString *)userId;

       

      You can then init a DBRestClient for that user normally.

        if(v1AccessToken.length>0)
    {
   //  [[DBSession sharedSession] updateAccessToken:v1AccessToken accessTokenSecret:v1AccessTokenSecret forUserId:ui];
      [[DBSession sharedSession] updateAccessToken:@"" accessTokenSecret:@"" forUserId:@""];
        if([DBSession sharedSession] != nil)
        {
        NSLog(@"Reauthenticating");
           [self performSelector:@selector(fetchAllDropboxData) withObject:nil afterDelay:0.2];
 
        }
