Box Preview SDK

This SDK makes it easy to present Box files in your iOS application.

NOTE: The Box iOS Preview SDK in Objective-C (prior to v3.0.0) has been moved from the main branch to the objective-c-maintenance branch. Going forward, the main branch will contain the iOS Preview SDK in Swift, starting with v3.0.0.

Requirements

Installing the SDK

Carthage

Step 1: Add to your Cartfile

Step 2: Update dependencies

$ carthage update --use-xcframeworks --platform iOS

Step 3: The xcframework in the Carthage/Build folder is already referenced in the BoxPreviewSDKSampleApp Xcode project.

For more detailed instructions, please see the official documentation for Carthage.

CocoaPods

Step 1: Add to your Podfile

pod 'BoxPreviewSDK', '~> 3.0'

Step 2: Install pod by running the following command in the directory with the Podfile

$ pod install

For more detailed instructions, please see the official documentation for Cocoapods.

Swift Package Manager

Importing BoxPreviewSDK into Project

Step 1: Click on Xcode project file

Step 2: Click on Swift Packages and click on the plus to add a package

Step 3: Enter the following repository url https://github.com/box/box-ios-preview-sdk.git and click next

Step 4: Leave the default settings to get the most recent release and click next to finish importing

The process should look like below:

Import Package

Adding BoxPreviewSDK as a Dependency

For detailed instructions, please see the official documentation for SPM.

Getting Started

To get started with the SDK, you'll need the Client ID and Client Secret of your app in the Box Developer Console. If you're familar with Getting Started with the OAuth2 Sample App in the Box Content SDK you'll find the process very similar.

Sample Apps

OAuth2 Sample App

A sample app using OAuth2 Authentication can be found in the repository here. This app demonstrates how to use the Box Preview SDK to make calls with OAuth2 Authentication, and can be run directly by entering your own credentials to log in.

To execute the sample app:

Step 1: Run carthage

$ cd SampleApps/OAuth2SampleApp
$ carthage update --use-xcframeworks --platform iOS

Step 2: Open Xcode Project File

$ open OAuth2SampleApp.xcodeproj

Step 3: Insert your client ID and client secret

First, find your OAuth2 app's client ID and secret from the Box Developer Console. Then, add these values to the sample app in Constants.swift file:

static let clientId = "YOUR CLIENT ID GOES HERE"
static let clientSecret = "YOUR CLIENT SECRET GOES HERE"

Step 4: Set redirect URL

Using the same client ID from the previous step, set the redirect URL for your application in the Box Developer Console to boxsdk-<<YOUR CLIENT ID>>://boxsdkoauth2redirect, where <<YOUR CLIENT ID>> is replaced with your client ID. For example, if your client ID were vvxff7v61xi7gqveejo8jh9d2z9xhox5 the redirect URL should be boxsdk-vvxff7v61xi7gqveejo8jh9d2z9xhox5://boxsdkoauth2redirect

Step 5: Insert your client ID to receive the redirect in the app

Open the Info.plist file in the sample app and find the key here: URL Types --> Item 0 --> URL Schemes --> Item 0 Using the same client ID from the previous step, set the value for Item 0 to boxsdk-<<YOUR CLIENT ID>>, where <<YOUR CLIENT ID>> is replaced with your client ID. For example, if your client ID were vvxff7v61xi7gqveejo8jh9d2z9xhox5 the redirect URL should be boxsdk-vvxff7v61xi7gqveejo8jh9d2z9xhox5

Info.plist setting

Step 6: Run the sample app

The app opens with a prompt to begin OAuth2.0 Authentication. Tap "OAuth2.0 Authentication" to proceed.

On the next screen, tap "Login".

An iOS System Dialog pops up asking if you agree to open a URL to authenticate. Tap "Continue" to proceed.

A Box login page loads. Enter your credentials and tap "Authorize" to proceed.

A confirmation screen displays the name of your application, as defined in the Box Developer Console, along with the scopes it is configured with. Tap "Grant access to Box" to grant your application access to the Box account.

The next screen displays all the files in the root folder for the account. If you don't see any files on the screen, check that you have files saved in the root folder of the Box account. Note that for simplicity, folders are not displayed in this sample app. From this screen you can tap the back arrow to log out, or tap a file name in the list to download it and display it. PDF and all iOS-supported image files are currently supported in the app.

CCG Auth Sample App

A sample app using CCG Authentication can be found in the repository here. This app demonstrates how to use the Box Preview SDK to make calls with CCG Authentication.

To execute the sample app:

Step 1: Run carthage

$ cd SampleApps/CCGSampleApp
$ carthage update --use-xcframeworks --platform iOS

Step 2: Open Xcode Project File

$ open CCGSampleApp.xcodeproj

Step 3: Insert your client ID and client secret

First, find your CCG app's client ID and secret from the Box Developer Console. Then, add these values to the sample app in Constants.swift file:

static let clientId = "YOUR CLIENT ID GOES HERE"
static let clientSecret = "YOUR CLIENT SECRET GOES HERE"

Step 4: Insert your userId if you to use CCG for user connection or enterpriseId for account service connection

You can find these values in your app at Box Developer Console. Then, add these values to the sample app in Constants.swift file:

static let userId = "YOUR USER ID GOES HERE"
static let enterpriseId = "YOUR ENTERPRISE ID GOES HERE"

Step 5: Uncomment the appropriate section in authorizeWithCCGClient() method in ViewController class.

As this sample app is prepared to CCG authentication as user and account service, you should uncomment Section 1 for CCG connection for account service or Section 2 for CCG connection for user account.

Step 6: Run the sample app

Open a PDF File

Tap a PDF file in the file list. A progress bar indicates the download progress as the file is retrieved from Box. When the progress reaches 100%, the document is displayed.

The toolbar at the top contains an arrow to go back to the file list, the file name, the current page number, an outline view button (if the document contains an outline) and a gallery view button. The toolbar can be toggled by tapping the document.

The outline view allows you to view the hierarchical structure of the document and offers quick navigation to a particular page.

The gallery view shows large thumbnails of each page and offers quick navigation to a particular page.

The document supports left and right swiping gestures to navigate one page at a time, pinch-to-zoom gestures and panning.

For PDF files containing multiple pages, the thumbnail navigation bar at the bottom of the screen allows for quick navigation through the entire document.

Open an Image File

Tap an image file (JPG, JPEG, PNG files are currently supported) in the file list. A progress bar indicates the download progress as the file is retrieved from Box. When the progress reaches 100%, the image is displayed.

The toolbar at the top contains an arrow to go back to the file list and the file name. The toolbar can be toggled by tapping the image.

The image supports pinch-to-zoom gestures and panning.

The Preview SDK supports opening multiple images at once, but this is currently not exposed in the sample app. Feel free to play around with this functionality on your own, by calling BoxPreviewSDK.openImageFiles(fileIds:selectedId:delegate:allowedAction:displayThumbnails)

Loads all images in thumbnail navigation bar at the bottom of the screen
Supports left and right swiping gestures to navigate from one image to the next
Gallery view

Future Enhancements

You can expect to see the following enhancements in future updates of the Box Preview SDK:

Support for more file types
Local file caching
Start app on last-viewed file
And more!

Versions

We use a modified version of Semantic Versioning for all changes. See version strategy for details which is effective from 30 July 2022.

Supported Version

Only the current MAJOR version of SDK is supported. New features, functionality, bug fixes, and security updates will only be added to the current MAJOR version.

A current release is on the leading edge of our SDK development, and is intended for customers who are in active development and want the latest and greatest features. Instead of stating a release date for a new feature, we set a fixed minor or patch release cadence of maximum 2-3 months (while we may release more often). At the same time, there is no schedule for major or breaking release. Instead, we will communicate one quarter in advance the upcoming breaking change to allow customers to plan for the upgrade. We always recommend that all users run the latest available minor release for whatever major version is in use. We highly recommend upgrading to the latest SDK major release at the earliest convenient time and before the EOL date.

Version schedule
