This SDK provides access to the Box V2 API. It currently supports file, folder, user, comment, and search operations.

Sample applications are forthcoming.

Add to your project

Dependent XCode Project + Framework

An alternative way to add the Box Cocoa SDK to your project is as a dependent XCode project. The BoxCocoaSDK framework is intended to be included in your application, rather than separately installed on a user's machine.

  1. Clone this repository into your project's directory. You can use git submodules if you want.
  2. Open your project in XCode.
  3. Drag BoxSDK.xcodeproj into the root of your project explorer.
    Dependent project

  4. Add the BoxCocoaSDK target as a target dependency.
    Target dependency

  5. Link with BoxCocoaSDK.framework
    Link with binary

  6. Create a build phase to copy the compiled framework into a 'Frameworks' directory in your application bundle.
    Copy to bundle

Note: steps 2-6 are covered in Apple's documentation on using frameworks.

  1. Add the -ObjC linker flag. This is needed to load categories defined in the SDK.
    Add linker flag

  2. #import <BoxCocoaSDK/BoxCocoaSDK.h>



Set your client ID and client secret on the SDK client:

[BoxCocoaSDK sharedSDK].OAuth2Session.clientID = @"YOUR_CLIENT_ID";
[BoxCocoaSDK sharedSDK].OAuth2Session.clientSecret = @"YOUR_CLIENT_SECRET";

One way to complete the OAuth2 flow is to have your app to register a custom URL scheme in order to receive an OAuth2 authorization code. In your Info.plist, register the following URL scheme:


Note: When setting up your service on Box, leave the OAuth2 redirect URI blank. The SDK will provide a custom redirect URI when issuing OAuth2 calls; doing so requires that no redirect URI be set in your service settings.


To authenticate your app with Box, you need to use OAuth2. It's easiest to use the user's default browser to execute the OAuth2 authentication and authorization. To get started, you simply ask the system to open the authentication URL:

NSURL *authURL = [[BoxCocoaSDK sharedSDK].OAuth2Session authorizeURL];
NSArray *urls = [NSArray arrayWithObject:authURL];
[[NSWorkspace sharedWorkspace] openURLs:urls
                withAppBundleIdentifier:nil //@"" if you want to specify Safari rather than the user's default browser

On successful authentication, your app will receive an "open in" request using the custom URL scheme you registered earlier. In your app delegate:

- (void)handleURLEvent:(NSAppleEventDescriptor *)event withReplyEvent:(NSAppleEventDescriptor *)replyEvent
    NSString *receivedUrlString = [[event paramDescriptorForKeyword:keyDirectObject] stringValue];
    [[BoxCocoaSDK sharedSDK].OAuth2Session performAuthorizationCodeGrantWithReceivedURL:[NSURL URLWithString:receivedUrlString]];

You can listen to notifications on [BoxCocoaSDK sharedSDK].OAuth2Session to be notified when a user becomes successfully authenticated.

Note: The SDK does not store tokens. We recommend storing the refresh token in the keychain and listening to notifications sent by the OAuth2Session. For more information, see the documetation for BoxOAuth2Session.

Making API calls

All SDK API calls are asynchronous. They are scheduled by the SDK on an NSOperationQueue. To be notified of API responses and errors, pass blocks to the SDK API call methods. These blocks are triggered once the API response has been received by the SDK.

Note: callbacks are not triggered on the main thread. Wrap updates to your app's UI in a dispatch_sync block on the main thread.

Get a folder's children

BoxCollectionBlock success = ^(BoxCollection *collection)
  // grab items from the collection, use the collection as a data source
  // for a table view, etc.

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

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

Get a file's information

BoxFileBlock success = ^(BoxFile *file)
  // manipulate the BoxFile.

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

[[BoxCocoaSDK sharedSDK].filesManager fileInfoWithID:folderID requestBuilder:nil success:success failure:failure];

Edit an item's information

To send data via the API, use a request builder. If we wish to move a file and change its name:

BoxFileBlock success = ^(BoxFile *file)
  // manipulate the BoxFile.

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

BoxFilesRequestBuilder *builder = [BoxFilesRequestBuilder alloc] init]; = @"My awesome file.txt"
builder.parentID = BoxAPIFolderIDRoot;

[[BoxCocoaSDK sharedSDK].filesManager editFileWithID:folderID requestBuilder:builder success:success failure:failure];

Upload a new file

BoxFileBlock fileBlock = ^(BoxFile *file)
  // manipulate resulting BoxFile

BoxAPIJSONFailureBlock failureBlock = ^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, NSDictionary *JSONDictionary)
  // handle failed upload

BoxAPIMultipartProgressBlock progressBlock = ^(unsigned long long totalBytes, unsigned long long bytesSent)
  // indicate progress of upload

BoxFilesRequestBuilder *builder = [[BoxFilesRequestBuilder alloc] init]; = @"Logo_Box_Blue_Whitebg_480x480.jpg";
builder.parentID = folderID;

NSString *path = [[NSBundle mainBundle] pathForResource:@"Logo_Box_Blue_Whitebg_480x480.jpg" ofType:nil];
NSInputStream *inputStream = [NSInputStream inputStreamWithFileAtPath:path];
NSDictionary *fileAttributes = [[NSFileManager defaultManager] attributesOfItemAtPath:path error:nil];
long long contentLength = [[fileAttributes objectForKey:NSFileSize] longLongValue];

[[BoxCocoaSDK sharedSDK].filesManager uploadFileWithInputStream:inputStream contentLength:contentLength MIMEType:nil requestBuilder:builder success:fileBlock failure:failureBlock progress:progressBlock];

Download a file

NSOutputStream *outputStream = [NSOutputStream outputStreamToFileAtPath:path append:NO];

BoxDownloadSuccessBlock successBlock = ^(NSString *downloadedFileID, long long expectedContentLength)
  // handle download, preview download, etc.

BoxDownloadFailureBlock failureBlock = ^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error)
  // handle download failure

BoxAPIDataProgressBlock progressBlock = ^(long long expectedTotalBytes, unsigned long long bytesReceived)
  // display progress

[[BoxCocoaSDK sharedSDK].filesManager downloadFileWithID:fileID outputStream:outputStream requestBuilder:nil success:successBlock failure:failureBlock progress:progressBlock];

Build Settings

The BoxCocoaSDK framework MUST be built with the OSX 10.8 SDK. It targets the 10.7 OS, and is not currently compatible with OSX 10.6 or earlier.


This SDK contains unit tests that are runnable with ./bin/ or alternatively rake spec.

To run tests specifically for the OS X platform, run tests with ./bin/ 10.8. This will compile BoxCocoaSDK and tests with the OS X 10.8 SDK.

Pull requests will not be accepted unless they include test coverage.


Documentation for this SDK is generated using appledoc. Documentation can be generated by running ./bin/ This script depends on the appledoc binary which can be downloaded using homebrew (brew install appledoc).

Documentation is hosted on this repo's github page.

Pull requests will not be accepted unless they include documentation.
