当用户收到错误或断开与XMPP的连接时,重新连接XMPP

Question

我已经在XMPP框架的帮助下实现了一个聊天应用程序.但是我收到的错误显示如下:

xmpp did receive error:-
Printing description of error:
<stream:error xmlns:stream="http://etherx.jabber.org/streams"><conflict xmlns="urn:ietf:params:xml:ns:xmpp-streams"></conflict><text xmlns="urn:ietf:params:xml:ns:xmpp-streams" lang="">Replaced by new connection</text></stream>

需要一些指导可能导致此错误的原因以及如何重新连接使用XMPP.

谢谢.

使用XMPPReconnect类..

@property (nonatomic, readonly) XMPPReconnect *xmppReconnect;

self.xmppReconnect = [[XMPPReconnect alloc] init];
[self.xmppReconnect activate:self.xmppStream];
[self.xmppReconnect addDelegate:self delegateQueue:dispatch_get_main_queue()];

并实现'XMPPReconnect'委托方法

- (void)xmppReconnect:(XMPPReconnect *)sender didDetectAccidentalDisconnect:(SCNetworkReachabilityFlags)connectionFlags
{
    NSLog(@"didDetectAccidentalDisconnect:%u",connectionFlags);
}
- (BOOL)xmppReconnect:(XMPPReconnect *)sender shouldAttemptAutoReconnect:(SCNetworkReachabilityFlags)reachabilityFlags
{
    NSLog(@"shouldAttemptAutoReconnect:%u",reachabilityFlags);
    return YES;
}
