Problems Integrating iOS project with Box SDK

votes

I am having problems with the instructions to integrate the Box iOS SDK with my project. I have followed the instructions on https://github.com/box/box-ios-sdk-v2 and I have gotten my app to successfully authenticate. Now, I am stuck in the Making API Calls section on the first part (Get a folder's children). My skeleton app to get this working just has basically two buttons for now: (1) link; and (2) get children. After I link, it asks to login to box.com; I do; then it comes back to an empty screen. Then, I have to run the program again, and then hit get children. I attempted to look at this link (iOS Box SDK BoxFolder.children always nil) and other questions to find a solution, but have not been able to. Here are the routines for each of those:

- (IBAction)linkAction:(id)sender {

    UIViewController *authorizationController = [[BoxAuthorizationViewController alloc] initWithAuthorizationURL:[[BoxSDK sharedSDK].OAuth2Session authorizeURL] redirectURI:nil]; 
    [self presentViewController:authorizationController animated:YES completion:nil]; 
}

- (IBAction)getChildrenAction:(id)sender { 

    BoxCollectionBlock success = ^(BoxCollection *collection) 
    { 
        dispatch_sync(dispatch_get_main_queue(), ^{ 
            NSLog(@"CHILDREN SUCCESS!!!"); 
        }); 
    }; 

    BoxAPIJSONFailureBlock failure = ^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, NSDictionary *JSONDictionary)
    {

        dispatch_sync(dispatch_get_main_queue(), ^{ 
            // handle errors 
            NSLog(@"CHILDREN ERROR, error = %@", error); 
        }); 
    }; 

    NSString *folderID = BoxAPIFolderIDRoot; 

    [[BoxSDK sharedSDK].foldersManager folderItemsWithID:folderID requestBuilder:nil success:success failure:failure]; 

}

HERE IS THE SUCCESSFUL OUTPUT AFTER LINKING:

There are files in my base directory at box.com. I would very much appreciate if anyone could help me with this. I have been attempting to follow the instructions explicitly. Or please let me know if you need any more information to diagnose this. Thank you very much.

the error code you had is 20002 which represent this state

access token is expired and the operation cannot be reenqueued because it already has been reenqueued before.

that's from box API GIT docs,so you should make sure about your access token is valid when you perform this operation.

Also,take a look at folder picker you should do something like that :

   if ([BoxSDK sharedSDK].OAuth2Session.isAuthorized)
{
    // in order to avoid a short lag, jump immediatly to the file picker if we are already authorized
    [self presentBoxFolderPicker];
}
else
{
    BoxFolderBlock success = ^(BoxFolder * folder) {
        [self presentBoxFolderPicker];
    };
    BoxAPIJSONFailureBlock failure = ^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, NSDictionary *JSONDictionary){
        [self boxError:error];
    };
    // try sending a hearbeat
    [[BoxSDK sharedSDK].foldersManager folderInfoWithID:BoxAPIFolderIDRoot
                                         requestBuilder:nil
                                                success:success
                                                failure:failure];
}
