ios - 当用户遇到错误或与 XMPP 断开连接时重新连接 XMPP

Question

我在XMPP 框架的帮助下实现了一个聊天应用程序。但是我收到一个错误，如图所示:

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>

需要有关可能导致此错误的原因以及如何使用 XMPP 重新连接的一些指导。

谢谢。

Answer 1

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(delegate)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;
}
