It is also integrated with AppleWatch, so you can control the slides from your wrist.
- iOS 8.0+ (Apple Watch & Keynote presentations support - iOS 9.0+)
SmartSlides workflow mechanism is based on Apple MultipeerConnectivity framework. Managing advertiser & browsing functionality implemented in AdvertisingManager & BrowsingManager classes.
For example, creating advertising session workhorse method:
func createPresentationSessionWithName(name : String) {
let presentationSession = PresentationSession(peer: MCPeerID(displayName: name), serviceType: kServiceTypeName, delegate: handler, index: 0, creationDate: NSDate(), broadcastingDevice: UIDevice().model)
sessions.append(presentationSession)
isActive = true
delegate?.connectivityManagerDidChangeState(self)
}Creating browsing session:
func instantiateObserverSessionWithName(name : String, browsingDelegate delegate : BrowsingHandlerDelegate?) {
browsingSession = MCSession(peer : MCPeerID(displayName: name), securityIdentity : nil, encryptionPreference: .None)
handler = BrowsingHandler(browsingDelegate: delegate)
(handler as! BrowsingHandler).connectivityDelegate = connectivityDelegate
browsingSession!.delegate = handler
}Both AdvertisingManager & BrowsingManager callbacks handling incapsulated in SessionHandler child classes - AdvertiserHandler & BrowsingHandler. These classes handle receiving messages data between peers, monitoring connection state & files transfering progress. Messaging between peers is also incapsulated via SessionCommand classes. Each message type, data transfers actions should be encapsulated in specific class, SessionCommand inheriter.
Simple ping message sending & receiving command class example:
class CommandPing: SessionCommand {
required init(parameters: [String : String]) {}
func execute(session: MCSession, peers: [MCPeerID]) -> (Bool) {
AppDelegate.shared.browsingManager.backPingMessageReceived()
return true
}
}
class CommandGetPing: SessionCommand{
required init(parameters: [String : String]) { }
func execute(session: MCSession, peers: [MCPeerID]) -> (Bool) {
do {
print("Ping received, ping sent back")
try session.sendData(SessionHandler.dataRequestForCommandType(.PingServer, parameters: nil), toPeers: peers, withMode: .Reliable)
return true
} catch let error as NSError {
print("Error sending ping: \(error)")
return false
}
}
}Presentation files can be provided by Dropbox (just create app page on [Dropbox] (https://www.dropbox.com/developers) and add key & secret string in AppDelegate), Mail app attachments and also 2 presentation files are already presented in the app by default
