MPC handler - how to stop the spinning activity monitor?

I have a multiplayer game and it simply connects via the MPC Handler. The connect window shows the people nearby and connected players. There's one of those spinning activity icons and it continues search spinning even though peers have successfully connected. It's not a button or Activity Indicator View. It's just there as part of the handler so I don't know how to stop it after a player has connected. Any ideas? Thanks. Screenshot. http://ift.tt/1AZ1hJK

import UIKit
import MultipeerConnectivity

class MPCHandler: NSObject, MCSessionDelegate {

var peerID:MCPeerID!
var session:MCSession!
var browser:MCBrowserViewController!
var advertiser:MCAdvertiserAssistant? = nil

func setupPeerWithDisplayName (displayName:String){
    peerID = MCPeerID(displayName: displayName)
}

func setupSession(){
    session = MCSession(peer: peerID)
    session.delegate = self
}

func setupBrowser(){
    browser = MCBrowserViewController(serviceType: "my-game", session: session)
}

func advertiseSelf(advertise:Bool){
    if advertise{
        advertiser = MCAdvertiserAssistant(serviceType: "my-game", discoveryInfo: nil, session: session)
        advertiser!.start()
    }else{
        advertiser?.stop()
        advertiser = nil
    }

}

func session(session: MCSession!, peer peerID: MCPeerID!, didChangeState state: MCSessionState) {
    let userInfo = ["peerID":peerID, "state":state.rawValue]
    dispatch_async(dispatch_get_main_queue(), { () -> Void in
        NSNotificationCenter.defaultCenter().postNotificationName("MPC_DidChangeStateNotification", object: nil, userInfo: userInfo)
    })
}

func session(session: MCSession!, didReceiveData data: NSData!, fromPeer peerID: MCPeerID!) {
    let userInfo = ["data":data, "peerID":peerID]
    dispatch_async(dispatch_get_main_queue(), { () -> Void in
        NSNotificationCenter.defaultCenter().postNotificationName("MPC_DidReceiveDataNotification", object: nil, userInfo: userInfo)
    })
}

func session(session: MCSession!, didFinishReceivingResourceWithName resourceName: String!, fromPeer peerID: MCPeerID!, atURL localURL: NSURL!, withError error: NSError!) {

}

}

func session(session: MCSession!, didReceiveStream stream: NSInputStream!, withName streamName: String!, fromPeer peerID: MCPeerID!) {
