SmartViewSDK iOS APIs

The iOS APIs provide methods and functionalities of the Smart View for iOS to users. With these APIs, we can communicate with Samsung Smart TV using an iOS device.

For more information, see the Samsung Developers

The swift API is used for mobile applications, to connect to SmartTV applications.

Download library

  • Download the SmartViewSDK iOS Sender SDK.

  • Install by CocoaPods

    • Add pod to Xcode project Open ‘Podfile’ and add smart-view-sdk for pod name
    • pod ‘smart-view-sdk’

Introduction

To facilitate communication between a iOS mobile device and Samsung Smart TV, the Smart View provides API’s for discovery, launch and communicate processes.

iOS APIs are provided as a dynamic library framework which implies that the applications using the framework can be submitted in the App Store only if their deployment target is iOS 8.0 or higher.

Steps:

1. Discovery
Discover compatible Samsung Smart TVs on your local network
2. Launch
Launch the installed app on TV
3. Connect
Connect and communicate with a TV application and other mobile devices

Discovery

You can discover a compatible Samsung Smart TV on your network using the ServiceSearch class. The workflow is as follows :

  • Start the Discovery Process.
  • Listen for notifications indicating services add/removed or implementing a ServiceSearchDelegate.
  • Stop the Discovery Process.

While discovering compatible TVs, you should display a list of discovered services to the user, allow them to select one and then communicate with the service selected. At any time you can get the list of the last discovered services.

Code Snippet with Examples (Swift):

	let serviceSearch = Service.search()
	init () {
    // The delegate is implemented as a weak reference
    serviceSearch.delegate = self
    serviceSearch.start()
	}

	// MARK: - ServiceSearchDelegate -

	func onServiceFound(service: Service) {
	    // Update your UI by using the serviceDiscovery.services array
	}
	
	func onServiceLost(service: Service) {
	    // Update your UI by using the serviceDiscovery.services array
	}
	
	// After the user connects to a device stop the search by calling
	serviceSearch.search( )
Alternatively, you can subscribe for notifications (Please unsubscribe when you are done).

	var didFindServiceObserver: AnyObject? = nil
	var didRemoveServiceObserver: AnyObject? = nil

	func listenForNotifications()
	{
    didFindServiceObserver = NSNotificationCenter.defaultCenter().addObserverForName(MSDidFindService, object: serviceSearch, queue: NSOperationQueue.mainQueue( )) { (notification) -> Void in
        let serviceSearch = notification.object as? ServiceSearch
        let service = notification.userInfo["service"] as? Service
    }

    didRemoveServiceObserver = NSNotificationCenter.defaultCenter().addObserverForName(MSDidRemoveService, object: serviceSearch, queue: NSOperationQueue.mainQueue( )) { (notification) -> Void in
        let serviceSearch = notification.object as? ServiceSearch
        let service = notification.userInfo["service"] as? Service
    }
	}

If you want to use notifications, closures and the main queue for your notification you can use the equivalent
convenience method call.

	public func on(notificationName: String, performClosure: (NSNotification!) -> void) -> AnyObject
	public func off(observer: AnyObject)

On selecting a service from the list of available services, you can interact with the service to get additional
information about the device or you can either start, stop, install, and retrieve information about applications.
Both installed applications and cloud applications can be launched.

BLE Device Discovery

SmartView framework supports discovery of Samsung devices via Bluetooth Low Energy in the surrounding area. BLE
discovery allows user to see the list of available TVs that user can connect with. BLE discovery does not support
retrieving the Service objects using Bluetooth currently.

The following example demonstrates how to launch BLE discovery and get the discovered devices.
Launch the search for BLE devices:

	let serviceSearch = Service.search()        
	serviceSearch.startUsingBLE()

Implement corresponding delegate method to handle the discovery events:

	func onFoundOnlyBLE(NameOfTV: String)
	{
    print("Found BLE device: \(NameOfTV)")
    // Update your UI...
	}

Launch

Once you have a selected device or “service” , you can now interact with both installed TV apps and Cloud apps.

Working With Installed TV Apps
Before you can work with an installed TV app, you must first know the “ID” of the TV application you want to work
with.If your TV app is still in development, you can use the folder name of your app as the id. Once the TV app
has been released into Samsung Apps, you must use the supplied app id.

There are four core functions for working with installed apps

  1. Service.createApplication (id: AnyObject, channelURI: String, args: [String:AnyObject]?) : Get reference to
    your TV app by app ID
  2. application.start (completionHandler: ((success: Bool, error: NSError?) -> Void)?) : Launch the TV app
  3. application.stop (completionHandler: ((success: Bool, error: NSError?) -> Void)?) : Terminate the TV app
  4. application.install (completionHandler: ((success: Bool, error: NSError?) -> Void)?) : Install the TV app.
	let uri: NSURL = app.getConfig().getWebAppUri();
	let channelID: String = "com.samsung.multiscreen.helloworld"

	let msApplication = service.createApplication(uri, channelURI: channelID, args: nil)!
	msApplication.connectionTimeout = 5.0

	// Launch the application without connecting to it
	msApplication.start() { (success, error) -> Void in
    if success  {
        print("App started")
    } else {
        print("App cannot start: \(error)")
    }
	}

Connect

You need to be connected to TV to communicate with any application. If you connect an application without calling
start() method it will be launched automatically before connecting.

	let uri: NSURL = app.getConfig().getWebAppUri();
	let channelID: String = "com.samsung.multiscreen.helloworld"

	let msApplication = service.createApplication(uri, channelURI: channelID, args: nil)!
	msApplication.connectionTimeout = 5.0
	msApplication.connect(attrs) { (client, error) -> Void in
    if client != nil {
        print("App connected")
    } else {
        print("App cannot connect: \(error)")
    }
	}

WoW (Wake on Wireless LAN)

Latest SmartViewSDK include Enhaned WOW feature

SDK 2.4.0 makes your app enable WOW function automatically without NO source code change.

  1. If your app have been connected once,

    • SDK manage the TV device list for WOW feature
    • SDK handles below Basic UI scenario
  2. Basic UI scenario

    • Turn the TV off (put to standby).
    • Appears marked as “TV_NAME(standby)” within 7 seconds.
    • Select the TV.
    • The TV power on
    • The TV WebApp(or DMP) should start loading on the TV.
    • The video should start playing on the TV.

Implement manually lower version of SDK 2.4.0

1.How to get MAC Address:

    service!.getDeviceInfo(5, completionHandler:
    {
            (deviceInfo, error) -> Void in         

                let device = deviceInfo!["device"]

                let wifi = device!["wifiMac"]

    })

2.Wake up TV:

	Service.WakeOnWirelessLan(macAddr)

3.Wake up TV and connect:

	//Default timeout for connection is used Service.DEFAULT_WOW_TIMEOUT_VALUE:NSTimeInterval = 6
    
    Service.WakeOnWirelessAndConnect(macAddr, uri, completionHandler: {(service, error) -> Void in
            if(service != nil)
            {
            let url = NSURL(string: "http://dev-multiscreen-examples.s3-website-us-west-1.amazonaws.com/examples/helloworld/tv/")

            let app = service?.createApplication(url!, channelURI: "com.samsung.multiscreen.msf20", args: nil)

            app?.delegate = self

            app?.connect()
        }
    })

	//Connect using custom timeout
	//let timeout:NSTimeInterval = 12

      Service.WakeOnWirelessAndConnect(macAddr, uri, timeout, completionHandler: {(service, error) -> Void in
                 .....      
         })
