Question

我无法收到服务器发送的IQ数据包。

如何在XMPPFramework中收听自定义IQ数据包？

这种方法不起作用：

- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq

我正在使用XMPPFramework。

<iq id="pvrequest" type="get">
<pvcommand xmlns='detayopenfireplugin:iq:customiq'>
<sendClassName>MainScreenController</sendClassName>
<sendMethodName>getMainUsersInfo</sendMethodName>
<spvcommand>eyJtbmFtZSI6ImdldE1haW5Vc2Vyc0luZm9Gb3JXZWIiLCJjbGlkIjoiMTAwIiwiY25hbWUiOiJvcmcuZGV0YXlzb2Z0LmF0b21pYy5kZXRheW9wZW5maXJlcGx1Z2luLnByb2Nlc3Nvci5leHRlcm5hbHByb2Nlc3Nvci5zdWJwcm9jZXNzb3IuQnVzaW5lc3MiLCJ1c2lkIjoiUDA0MDUifQ==</spvcommand>
</pvcommand>
</iq>

您是否在视图控制器中为xmpp分配了委托。

 (void)setupStream
{
NSAssert(xmppStream == nil, @"Method setupStream invoked multiple times");

// Setup xmpp stream
// 
// The XMPPStream is the base class for all activity.
// Everything else plugs into the xmppStream, such as modules/extensions and delegates.

xmppStream = [[XMPPStream alloc] init];

#if !TARGET_IPHONE_SIMULATOR
{
    // Want xmpp to run in the background?
    // 
    // P.S. - The simulator doesn't support backgrounding yet.
    //        When you try to set the associated property on the simulator, it simply fails.
    //        And when you background an app on the simulator,
    //        it just queues network traffic til the app is foregrounded again.
    //        We are patiently waiting for a fix from Apple.
    //        If you do enableBackgroundingOnSocket on the simulator,
    //        you will simply see an error message from the xmpp stack when it fails to set the property.

    xmppStream.enableBackgroundingOnSocket = YES;
}
#endif

// Setup reconnect
// 
// The XMPPReconnect module monitors for "accidental disconnections" and
// automatically reconnects the stream for you.
// There's a bunch more information in the XMPPReconnect header file.

xmppReconnect = [[XMPPReconnect alloc] init];

// Setup roster
// 
// The XMPPRoster handles the xmpp protocol stuff related to the roster.
// The storage for the roster is abstracted.
// So you can use any storage mechanism you want.
// You can store it all in memory, or use core data and store it on disk, or use core data with an in-memory store,
// or setup your own using raw SQLite, or create your own storage mechanism.
// You can do it however you like! It's your application.
// But you do need to provide the roster with some storage facility.

xmppRosterStorage = [[XMPPRosterCoreDataStorage alloc] init];
//  xmppRosterStorage = [[XMPPRosterCoreDataStorage alloc] initWithInMemoryStore];

xmppRoster = [[XMPPRoster alloc] initWithRosterStorage:xmppRosterStorage];

xmppRoster.autoFetchRoster = YES;
xmppRoster.autoAcceptKnownPresenceSubscriptionRequests = YES;

// Setup vCard support
// 
// The vCard Avatar module works in conjuction with the standard vCard Temp module to download user avatars.
// The XMPPRoster will automatically integrate with XMPPvCardAvatarModule to cache roster photos in the roster.

xmppvCardStorage = [XMPPvCardCoreDataStorage sharedInstance];
xmppvCardTempModule = [[XMPPvCardTempModule alloc] initWithvCardStorage:xmppvCardStorage];

xmppvCardAvatarModule = [[XMPPvCardAvatarModule alloc] initWithvCardTempModule:xmppvCardTempModule];

// Setup capabilities
// 
// The XMPPCapabilities module handles all the complex hashing of the caps protocol (XEP-0115).
// Basically, when other clients broadcast their presence on the network
// they include information about what capabilities their client supports (audio, video, file transfer, etc).
// But as you can imagine, this list starts to get pretty big.
// This is where the hashing stuff comes into play.
// Most people running the same version of the same client are going to have the same list of capabilities.
// So the protocol defines a standardized way to hash the list of capabilities.
// Clients then broadcast the tiny hash instead of the big list.
// The XMPPCapabilities protocol automatically handles figuring out what these hashes mean,
// and also persistently storing the hashes so lookups aren't needed in the future.
// 
// Similarly to the roster, the storage of the module is abstracted.
// You are strongly encouraged to persist caps information across sessions.
// 
// The XMPPCapabilitiesCoreDataStorage is an ideal solution.
// It can also be shared amongst multiple streams to further reduce hash lookups.

xmppCapabilitiesStorage = [XMPPCapabilitiesCoreDataStorage sharedInstance];
xmppCapabilities = [[XMPPCapabilities alloc] initWithCapabilitiesStorage:xmppCapabilitiesStorage];

xmppCapabilities.autoFetchHashedCapabilities = YES;
xmppCapabilities.autoFetchNonHashedCapabilities = NO;

// Activate xmpp modules

[xmppReconnect         activate:xmppStream];
[xmppRoster            activate:xmppStream];
[xmppvCardTempModule   activate:xmppStream];
[xmppvCardAvatarModule activate:xmppStream];
[xmppCapabilities      activate:xmppStream];

// Add ourself as a delegate to anything we may be interested in

[xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];
[xmppRoster addDelegate:self delegateQueue:dispatch_get_main_queue()];

// Optional:
// 
// Replace me with the proper domain and port.
// The example below is setup for a typical google talk account.
// 
// If you don't supply a hostName, then it will be automatically resolved using the JID (below).
// For example, if you supply a JID like 'user@quack.com/rsrc'
// then the xmpp framework will follow the xmpp specification, and do a SRV lookup for quack.com.
// 
// If you don't specify a hostPort, then the default (5222) will be used.

//  [xmppStream setHostName:@"talk.google.com"];
//  [xmppStream setHostPort:5222];  


// You may need to alter these settings depending on the server you're connecting to
allowSelfSignedCertificates = NO;
allowSSLHostNameMismatch = NO;
}
