J'ai une question J'ai fait une petite application de connectivité Multipeer par a tutorial Je réécris le code un peu pour qu'il fonctionne avec swift 2.0. Tout fonctionne bien mais si j'envoie ma simulation une invitation de mon iPhone 6s, elle ne se connecte pas pourquoi?Swift2.0 Multipeer Connectivité Impossible de se connecter
code:
import MultipeerConnectivity
import UIKit
class ViewController: UIViewController, MCSessionDelegate, MCBrowserViewControllerDelegate {
var browser : MCBrowserViewController!
var assistant : MCAdvertiserAssistant!
var session : MCSession!
var peerID: MCPeerID!
@IBOutlet var chatView: UITextView!
@IBOutlet var messageField: UITextField!
override func viewDidLoad() {
super.viewDidLoad()
self.peerID = MCPeerID(displayName: UIDevice.currentDevice().name)
print(UIDevice.currentDevice().name)
//self.session = MCSession(peer: peerID, securityIdentity: nil, encryptionPreference: .Required)
self.session = MCSession(peer: self.peerID)
self.session.delegate = self
// create the browser viewcontroller with a unique service name
self.browser = MCBrowserViewController(serviceType: "LCOC-Chat", session: self.session)
self.browser.delegate = self
// tell the assistant to start advertising our fabulous chat
self.assistant = MCAdvertiserAssistant(serviceType:"LCOC-Chat", discoveryInfo:nil, session:self.session)
self.assistant.start()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
@IBAction func showBrowser(sender: UIButton) {
self.presentViewController(self.browser, animated: true, completion: nil)
}
@IBAction func sendChat(sender: UIButton) {
if self.session.connectedPeers.count > 0 {
if let msg = self.messageField.text!.dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: false) {
// 3
do {
try self.session.sendData(msg, toPeers: self.session.connectedPeers, withMode: MCSessionSendDataMode.Unreliable)
} catch let error as NSError {
let ac = UIAlertController(title: "Send error", message: error.localizedDescription, preferredStyle: .Alert)
ac.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
presentViewController(ac, animated: true, completion: nil)
}
}
}
//-----------------this might ne3ed to be UNCOMMENTED!!!
//self.updateChat(self.messageField.text!, fromPeer: self.peerID)
self.messageField.text = ""
}
func updateChat(text : String, fromPeer peerID: MCPeerID) {
// Appends some text to the chat view
print("Incoming msg: \(text)")
// If this peer ID is the local device's peer ID, then show the name
// as "Me"
var name : String
switch peerID {
case self.peerID:
name = "Me"
default:
name = peerID.displayName
}
// Add the name to the message and display it
let message = "\(name): \(text)\n"
self.chatView.text = self.chatView.text + message
}

dismissViewControllerAnimated(true, completion: nil)
}
func browserViewController(browserViewController: MCBrowserViewController, shouldPresentNearbyPeer peerID: MCPeerID, withDiscoveryInfo info: [String : String]?) -> Bool {
return true
}
//---------------------------------------Session
func session(session: MCSession, didReceiveData data: NSData, fromPeer peerID: MCPeerID) {
// Called when a peer sends an NSData to us
// This needs to run on the main queue
dispatch_async(dispatch_get_main_queue()) {

//let msg = NSString(data: data, encoding: NSUTF8StringEncoding)
let msg = String(data: data, encoding: NSUTF8StringEncoding)!

}
// The following methods do nothing, but the MCSessionDelegate protocol
// requires that we implement them.
