Question

在应用程序中，正在调用invitationDidFail，有时它正确连接，但有时它不会...

否认连接的可能原因是什么？

// Display an alert sheet indicating a failure to connect to the peer.
- (void) invitationDidFail:(SessionManager *)session fromPeer:(NSString *)participantID
{
NSString *str;
if (alertView.visible) {
    // Peer cancelled invitation before it could be accepted/rejected
    // Close the invitation dialog before opening an error dialog
    [alertView dismissWithClickedButtonIndex:0 animated:NO];
    [alertView release];
    str = [NSString stringWithFormat:@"%@ is busy.\nPlease again", participantID];
    //[peerList removeAllObjects];
    [self peerListDidChange:nil];
    [self.tableData reloadData];
    //[self TwoPlayer:self];
} else {
    // Peer rejected invitation or exited app.
    str = [NSString stringWithFormat:@"%@ is busy.\nPlease try again", participantID];
    //[peerList removeAllObjects];
    [self peerListDidChange:nil];
    [self.tableData reloadData];
    //[self TwoPlayer:self];
  }
}

即使它不调用此方法，确定设备未与任何其他设备配对，那么有时它接受并调用didReceivedInvitation方法的原因是什么，或者有时它通过调用invitationDidFail来拒绝。< / p>

// Invitation dialog due to peer attempting to connect.
- (void) didReceiveInvitation:(SessionManager *)session fromPeer:(NSString     *)participantID;
{
[alertView dismissWithClickedButtonIndex:1 animated:NO];

NSString *str = [NSString stringWithFormat:@"Incoming Invite from %@", participantID];
if (alertView.visible) {
    [alertView dismissWithClickedButtonIndex:0 animated:NO];
    [alertView release];
}
alertView = [[UIAlertView alloc] 
             initWithTitle:str
             message:@"Do you wish to accept?" 
             delegate:self 
             cancelButtonTitle:@"Decline" 
             otherButtonTitles:nil];
[alertView addButtonWithTitle:@"Accept"]; 
[alertView show];
}

当我最近使用连接编写应用程序时，我使用了GKSession。我花了几周的时间尝试用它调试连接问题，最后我放弃了并停止使用它。连接时GKSession似乎存在许多问题，特别是如果断开连接然后尝试在短时间内重新连接（短时间可能是1分钟或更长时间）。似乎连接没有正确删除，然后它没有正确地重新创建连接。

最后，我拿出了所有GKSession代码并改为使用它。做了一个享受 - 没有更多的连接问题。

GCD Async Socket

什么GKSession不会在每次尝试时连接？
