A custom Swift utility "FBSDKLiveVideo" to stream Facebook Live videos on iOS.
The following example would create a full-screen live video preview that is started when the user taps the trigger button linked in your Storyboard.
class ViewController: UIViewController {
var liveVideo: FBSDKLiveVideo!
override func viewDidLoad() {
super.viewDidLoad()
// Create the live video service
liveVideo = FBSDKLiveVideo(
delegate: self,
previewSize: self.view.bounds,
videoSize: CGSize(width: 1280, height: 720)
)
// Optional: Configure the live-video (see the source for all options)
liveVideo.privacy = .me // or .friends, .friendsOfFriends, .custom
liveVideo.audience = "me" // or your user-id, page-id, event-id, group-id, ...
// Optional: Add the preview view of the stream to your container view.
myView.addSubView(liveVideo.preview)
}
@IBAction func recordButtonTapped() {
liveVideo.start()
}
@IBAction func stopButtonTapped() {
liveVideo.stop();
}
@IBAction func adBreakButtonTapped() {
liveVideo.adBreakStartNow = true
liveVido.update();
}
@IBAction func deleteButtonTapped() {
liveVido.delete();
}
}
extension ViewController: FBSDKLiveVideoDelegate {
func liveVideo(_ liveVideo: FBSDKLiveVideo, didStartWith session: FBSDKLiveVideoSession) {
// Live video started
}
func liveVideo(_ liveVideo: FBSDKLiveVideo, didStopWith session: FBSDKLiveVideoSession) {
// Live video ended
}
func liveVideo(_ liveVideo: FBSDKLiveVideo, didErrorWith: Error) {
// Live video errored
}
func liveVideo(_ liveVideo: FBSDKLiveVideo, didChange sessionState: FBSDKLiveVideoSessionState) {
// Live video changed session state
// One of: .none, .previewStarted, .starting, .started, .ended, .error
}
func liveVideo(_ liveVideo: FBSDKLiveVideo, didAdd cameraSource: FBSDKLiveVideoSession) {
// New camera source added to the stream
}
func liveVideo(_ liveVideo: FBSDKLiveVideo, didUpdate session: FBSDKLiveVideoSession) {
// Live video was updated through update()
}
func liveVideo(_ liveVideo: FBSDKLiveVideo, didDelete session: FBSDKLiveVideoSession) {
// Live video was deleted through delete()
}

facebook-live-ios-sample.xcworkspacefile in Xcode - Change the app-id inside the
Info.plistto match your app. Ensure to configure the App-ID correctly - Run the project on your iOS device! By default, it will only start a live-stream to your private audience ("Only me")
