iOS Multiper连接框架邀请函哈德勒似乎不接受？ [英] iOS Multipeer connectivity framework invitationHandler doesn't seem to accept?

问题描述

我第一次使用mutlipeer连接框架，我想要编程（不是辅助类）控制。

一切都按照描述当我在两个独立的设备上运行我的代码，直到广告客户收到委托回调的时候：

浏览客户端的委托回调在发现广告客户时被调用：

   - （void）browser：（MCNearbyServiceBrowser *）browser foundPeer：（MCPeerID *）peerID withDiscoveryInfo：（NSDictionary *）info {
 [[UIAlertView alloc] initWithTitle：@Peer Found消息：peerID.displayName委托：nil cancelButtonTitle：@OKotherButtonTitles：nil，nil] show]; 
 
 _session = [[MCSession alloc] initWithPeer：_myPeerID]; 
 _session.delegate = self; 
 
 //连接到发现的对等体。 
 [_browser invitePeer：peerID toSession：_session withContext：nil timeout：30.0]; 
 [_browser stopBrowsingForPeers]; 
  

}

然后广告客户的代表回调在收到邀请时被调用：

   - （void）advertiser：（MCNearbyServiceAdvertiser *）广告客户didReceiveInvitationFromPeer :( MCPeerID *） peerID withContext：（NSData *）context invitationHandler：（void（^）（BOOL，MCSession *））invitationHandler {
 
 //当我的代码运行时，一切看起来都正确。 
 // eg。 peerID绝对是我的浏览器客户端的显示名称。
 
 _session = [[MCSession alloc] initWithPeer：_myPeerID]; 
 _session.delegate = self; 
 
 //使用简单版本进行测试...接受所有邀请。 
 inviteHandler（YES，_session）; 
 
 //停止广告
 [_advertiser stopAdvertisingPeer]; 
} 
  

调用'invitationHandler（YES，_session）'后，看起来像浏览客户端和广告客户端之间从未建立连接。

在客户端设备上的MCSession对象上，我没有收到任何委托回调（一次或两次我收到一个MCSessionStateNotConnected）。我会以为我会收到MCSession委托回调：

   - （void）session：（MCSession *）session peer： （MCPeerID *）peerID didChangeState :( MCSessionState）状态; 
  

我错过了什么吗？有其他人遇到这个问题吗？

解决方案

有一个苹果明显知道的错误。

这是导致发现的原因：为什么我的MCSession对等体随机断开？ / a>

您必须实现以下代理回调，即使它在文档中列为可选...

（MCPessionID *）peerID certificateHandler：（void（^）（BOOL accept））certificateHandler（（*））
{
certificateHandler（YES）;
}

I'm using the mutlipeer connectivity framework for the first time, and I want programmatic ( not with the assistant classes) control.

Everything is working exactly as described when I run my code on two separate devices up until the point when the 'advertiser' receives the delegate callback:

The browsing client's delegate callback is called when it discovers the advertiser:

-(void)browser:(MCNearbyServiceBrowser *)browser foundPeer:(MCPeerID *)peerID withDiscoveryInfo:(NSDictionary *)info{
    [[[UIAlertView alloc] initWithTitle:@"Peer Found" message:peerID.displayName delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil, nil] show];

    _session = [[MCSession alloc] initWithPeer:_myPeerID];
    _session.delegate = self;

    //connect to the discovered peer.
    [_browser invitePeer:peerID toSession:_session withContext:nil timeout:30.0];
    [_browser stopBrowsingForPeers];

}

Then the advertising client's delegate callback is called when it receives the invite:

-(void)advertiser:(MCNearbyServiceAdvertiser *)advertiser didReceiveInvitationFromPeer:(MCPeerID *)peerID withContext:(NSData *)context invitationHandler:(void (^)(BOOL, MCSession *))invitationHandler{

    //when my code runs, everything looks correct here. 
    //eg. peerID is definitely my 'browser' client's display name etc.

    _session = [[MCSession alloc] initWithPeer:_myPeerID];
    _session.delegate = self;

    //using a simple version for testing... accept all invites.
    invitationHandler(YES, _session);

    //stop advertising now.
    [_advertiser stopAdvertisingPeer];
}

After 'invitationHandler(YES, _session)' is called, it seems like the connection is never established between the 'browsing' client and the 'advertising' client.

I don't ever receive any delegate callbacks (once or twice I received a MCSessionStateNotConnected ) on the MCSession objects on either client device. I would have thought I would have received the MCSession delegate callback:

-(void)session:(MCSession *)session peer:(MCPeerID *)peerID didChangeState:(MCSessionState)state;

Am I missing something? Has anyone else come across this issue?

解决方案

There is a bug that Apple is aware of apparently.

This is what led to the discovery: Why does my MCSession peer disconnect randomly?

You must implement the following delegate callback even though it is listed as optional in the docs...

- (void) session:(MCSession *)session didReceiveCertificate:(NSArray *)certificate fromPeer:(MCPeerID *)peerID certificateHandler:(void (^)(BOOL accept))certificateHandler
{
 certificateHandler(YES);
}
