Microsoft Face API: iOS Client Library & Sample

This repo contains the iOS client library & sample for the Microsoft Face API, an offering within Microsoft Cognitive Services, formerly known as Project Oxford.

The Client Library

The easiest way to consume the iOS client library is via CocoaPods. To install via Cocoapods:

  1. Install Cocoapods - Follow the getting started guide to install Cocoapods.
  2. Add the following to your Podfile : pod 'ProjectOxfordFace'.
  3. Run the command pod install to install the latest ProjectOxfordFace pod.
  4. Add #import <ProjectOxfordFace/MPOFaceSDK.h> to all files that need to reference the SDK.

The Sample

The sample app demonstrates the use of the Microsoft Face API iOS client library. The sample shows scenarios such as face detection, face verification, and face grouping.


iOS must be version 8.1 or higher.

Building and running the sample

The sample app should already have the necessary Pods shipped with it. Open the ProjectOxfordFace.xcworkspace in Xcode and build.

  1. First, you must obtain a Face API subscription key by following the instructions on our website.
  2. Once in Xcode, under the example subdirectory, navigate to the file MPOAppDelegate.h and insert your subscription key for the Face API.
  3. To run the sample app, ensure that the target on top left side of Xcode is selected as ProjectOxfordFace-Example and select the play button or select Product > Run on the menu bar.
  4. Once the app is launched, click on the buttons to try out the different scenarios.

Microsoft will receive the images you upload and may use them to improve Face API and related services. By submitting an image, you confirm you have consent from everyone in it.

Having issues?

  1. Make sure you have selected ProjectOxfordFace-Example as the target.
  2. Make sure you have included the subscription key in MPOTestConstants.h.
  3. Make sure you have opened the .xcworkspace file and not the .xcodeproj file in Xcode.
  4. Make sure you have used the correct Deployment Team profile.
  5. Make sure you are running iOS 8.1 or higher.

Running and exploring the unit tests

Unit tests that demonstrate various Microsoft Cognitive Services scenarios such as detection, identification, grouping, similarity, verification, and face lists are located at Example/Tests.

To run the unit tests, first insert your subscription key in MPOTestConstants.h and then select the test navigator pane in Xcode to display all of the tests which can be run.
