多重连接框架 - 断开的对等体在MCBrowserController中保持会话

Question

这里有一个类似的问题：Multipeer Connectivity Framework - Lost Peer stays in Session

但遗憾的是答案没有帮助，或者我误解了它们。

我有我的多重连接应用程序，并且还测试了Apples自己的MultipeerGroupChat应用程序。

当对等方断开连接时，有时它们会留在会话中。当对等体尝试重新连接时，这会导致连接失败。

我在applicationWillTerminate中尝试过[session disconnect]，但它仍然会发生。

如何让MCBrowserViewController更新自己与谁连接以及谁不是？

-(id)init{
self = [super init];
if (self) {
    _peerID = nil;
    _session = nil;
    _browser = nil;
    _advertiser = nil;
}
    _appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
    return self;
}

-(void)setupMCBrowser{
_browser = [[MCBrowserViewController alloc] initWithServiceType:@"session" session:_session];
_browser.maximumNumberOfPeers = 8;
}

-(void)session:(MCSession *)session peer:(MCPeerID *)peerID didChangeState:(MCSessionState)state{
NSDictionary *dict = @{@"peerID": peerID,
                       @"state" : [NSNumber numberWithInt:state]
                       };

[[NSNotificationCenter defaultCenter] postNotificationName:@"MCDidChangeStateNotification"
                                                    object:nil
                                                  userInfo:dict];

switch (state)
{

    case MCSessionStateConnecting:
    {

        _statusID = @"Connecting";
        break;
    }

    case MCSessionStateConnected:
    {

        _statusID = @"Connected";
        if (_firstPeer == NULL){
            _firstPeer = peerID.displayName;
        }
        else if (_secondPeer == NULL){
            _secondPeer = peerID.displayName;
        }
        else if (_thirdPeer == NULL){
            _thirdPeer = peerID.displayName;
        }
        break;
    }

    case MCSessionStateNotConnected:
    {
        if ([peerID isEqual:_firstPeer]){
            _firstPeer = NULL;
        }
        else if ([peerID isEqual:_secondPeer]){
            _secondPeer = NULL;
        }
        else if ([peerID isEqual:_thirdPeer]){
            _thirdPeer = NULL;
        }
        _statusID = @"Connection Lost";
        break;
    }
}
