ios - XMPP 在 objective-C 中实现 XEP-0198

Question

注意:服务器已经安装并运行流管理。

这是我的代码:

XMPPStreamManagementMemoryStorage *storage1=[[XMPPStreamManagementMemoryStorage alloc] init];
xmppStreamManagement=[[XMPPStreamManagement alloc] initWithStorage:storage1];
xmppStreamManagement.autoResume = YES;
[xmppStreamManagement enableStreamManagementWithResumption:TRUE maxTimeout:5];
[xmppStreamManagement addDelegate:self delegateQueue:dispatch_get_main_queue()];
[xmppStreamManagement activate:xmppStream];
 [xmppStreamManagement requestAck];

我也实现了委托(delegate)方法。 但是我既没有在委托(delegate)方法中得到响应，也没有看到流管理工作。

它将如何工作以及我们如何验证它？

这里，如果我在iOS端实现流管理成功，那么离线消息会自动丢失

- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message

我们将不胜感激。

在您的 iOS 应用中启用 XMPPStreamManagement 非常容易。

使用XMPPStreamManagementMemoryStorage 初始化您的XMPPStreamManagement 实例。

XMPPStreamManagementMemoryStorage *xmppSMMS = [[XMPPStreamManagementMemoryStorage alloc] init];
xmppStreamManagement = [[XMPPStreamManagement alloc] initWithStorage:xmppSMMS];

添加你的实现类作为它的委托(delegate)

[xmppStreamManagement addDelegate:self delegateQueue:dispatch_get_main_queue()];

一旦 XMPPStream 已连接并发生绑定(bind)，现在启用流管理。

[xmppStreamManagement activate:xmppStream];
xmppStreamManagement.autoResume = YES;
[xmppStreamManagement enableStreamManagementWithResumption:YES maxTimeout:0];
[xmppStreamManagement requestAck];

实现委托(delegate)方法

- (void)xmppStreamManagement:(XMPPStreamManagement *)sender wasEnabled:(NSXMLElement *)enabled{
}

- (void)xmppStreamManagement:(XMPPStreamManagement *)sender wasNotEnabled:(NSXMLElement *)failed{
}

- (void)xmppStreamManagement:(XMPPStreamManagement *)sender didReceiveAckForStanzaIds:(NSArray *)stanzaIds{
}
