XMPPFramework-创建一个XMPPRoom [英] XMPPFramework - Create an XMPPRoom

问题描述

我一直在尝试使用下面提到的代码创建XMPPRoom，但是我在线查看了各种示例，但是当我使用此代码时，不会调用委托xmppRoomDidCreate或xmppRoomDidJoin委托.我不确定我在这里做错什么了吗?

PS:xmppStream的委托确实被调用，它已连接并得到授权，但是问题是XMPPRoom委托...

- (void)createChatRoom
{
    NSString *jabberID = @"[e-mail]";
    self.xmppStream.hostName = @"testservice.com";


    self.xmppStream = [[XMPPStream alloc]init];
    [self.xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];

    [self.xmppStream setMyJID:[XMPPJID jidWithString:jabberID]];

    NSError *error = nil;

    if (![self.xmppStream connectWithTimeout:XMPPStreamTimeoutNone error:&error]) {
        UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Error" message:[NSString stringWithFormat:@"Cannot connect to server %@",[error localizedDescription]] delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil];
        [alert show];

        return;
    }

    // Configure xmppRoom
    XMPPJID *roomJID = [XMPPJID jidWithString:@"[e-mail]"];

    XMPPRoomMemoryStorage *roomMemoryStorage = [[XMPPRoomMemoryStorage alloc] init];

    XMPPRoom *xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:roomMemoryStorage
                                                           jid:roomJID
                                                 dispatchQueue:dispatch_get_main_queue()];

    [xmppRoom activate:self.xmppStream];
    [xmppRoom addDelegate:self delegateQueue:dispatch_get_main_queue()];
}

解决方案

您是否在要监视XMPPRoom委托的视图控制器的.h文件中添加了<XMPPRoomDelegate>协议?

应该是这样的:@interface YourViewController : UIViewController <..., XMPPRoomDelegate>.

当然#import "XMPPRoom.h"也应该在提到的视图控制器的.h文件中.

添加:

您必须设置XMPPStream对象，使用XMPPJID连接到聊天"服务器(在大多数情况下为Jabber服务器)，然后侦听服务器响应，然后使用密码进行身份验证，然后从XMPPRoom开始如果上面提到的所有内容都进行得很好，那么就可以创建.

示例:

- (void)setupStream
{
    NSAssert(xmppStream == nil, @"Method setupStream invoked multiple times");
    xmppStream = [[XMPPStream alloc] init];

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

然后连接到服务器:

[self setupStream];

NSString *myJID = @"...";

[xmppStream setMyJID:[XMPPJID jidWithString:myJID]];

NSError *error2;
if ([xmppStream connect:&error2])
{
    NSLog(@"Connected to XMPP.");
}
else
{
    NSLog(@"Error connecting to XMPP: %@", [error2 localizedDescription]);
}

收听服务器响应(不要忘记在.h文件中添加<XMPPStreamDelegate>):

- (void)xmppStreamDidConnect:(XMPPStream *)sender
{    
    NSError *error;    
    if ([[self xmppStream] authenticateWithPassword:password error:&error])
    {
        NSLog(@"Authentificated to XMPP.");
    }
    else
    {
        NSLog(@"Error authentificating to XMPP: %@", [error localizedDescription]);
    }
}

监听服务器对身份验证状态的响应:

- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender
{
    NSLog(@"%s", __FUNCTION__);
    XMPPPresence *presence = [XMPPPresence presenceWithType:@"available"];
    [sender sendElement:presence]; 
}

，然后在身份验证成功后尝试通过调用函数来创建XMPPRoom:

- (void)createChatRoom
{    
    // Configure xmppRoom
    XMPPJID *roomJID = [XMPPJID jidWithString:@"[e-mail]"];

    XMPPRoomMemoryStorage *roomMemoryStorage = [[XMPPRoomMemoryStorage alloc] init];

    XMPPRoom *xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:roomMemoryStorage
                                                           jid:roomJID
                                                 dispatchQueue:dispatch_get_main_queue()];

    [xmppRoom activate:self.xmppStream];
    [xmppRoom addDelegate:self delegateQueue:dispatch_get_main_queue()];
    [xmppRoom joinRoomUsingNickname:user history:nil];
}

I have been trying to create a XMPPRoom using the below mentioned code, i have looked at various examples online however when i use this code, the delegate xmppRoomDidCreate or xmppRoomDidJoin delegates doesn't get called. I'm not sure what am i doing wrong here?

PS: the delegates of xmppStream do get called, it gets connected and authorized however, the issue is XMPPRoom delegates...

- (void)createChatRoom
{
    NSString *jabberID = @"[e-mail]";
    self.xmppStream.hostName = @"testservice.com";


    self.xmppStream = [[XMPPStream alloc]init];
    [self.xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];

    [self.xmppStream setMyJID:[XMPPJID jidWithString:jabberID]];

    NSError *error = nil;

    if (![self.xmppStream connectWithTimeout:XMPPStreamTimeoutNone error:&error]) {
        UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Error" message:[NSString stringWithFormat:@"Cannot connect to server %@",[error localizedDescription]] delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil];
        [alert show];

        return;
    }

    // Configure xmppRoom
    XMPPJID *roomJID = [XMPPJID jidWithString:@"[e-mail]"];

    XMPPRoomMemoryStorage *roomMemoryStorage = [[XMPPRoomMemoryStorage alloc] init];

    XMPPRoom *xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:roomMemoryStorage
                                                           jid:roomJID
                                                 dispatchQueue:dispatch_get_main_queue()];

    [xmppRoom activate:self.xmppStream];
    [xmppRoom addDelegate:self delegateQueue:dispatch_get_main_queue()];
}

解决方案

Did you add <XMPPRoomDelegate> protocol in the .h file of the view controller in which you want to monitor XMPPRoom's delegates?

It should be something like this: @interface YourViewController : UIViewController <..., XMPPRoomDelegate>.

Of course #import "XMPPRoom.h" should be also in .h file of the mentioned view controller.

ADDITION:

You have to setup XMPPStream object, connect to your 'chat' server (in most cases Jabber server) with XMPPJID, then listen for server response, then authentificate with the password and then to start with XMPPRoom creation if everything mentioned from above goes well.

Example:

- (void)setupStream
{
    NSAssert(xmppStream == nil, @"Method setupStream invoked multiple times");
    xmppStream = [[XMPPStream alloc] init];

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

Then to connect to server:

[self setupStream];

NSString *myJID = @"...";

[xmppStream setMyJID:[XMPPJID jidWithString:myJID]];

NSError *error2;
if ([xmppStream connect:&error2])
{
    NSLog(@"Connected to XMPP.");
}
else
{
    NSLog(@"Error connecting to XMPP: %@", [error2 localizedDescription]);
}

Listen for server response (do not forget to add <XMPPStreamDelegate> in .h file):

- (void)xmppStreamDidConnect:(XMPPStream *)sender
{    
    NSError *error;    
    if ([[self xmppStream] authenticateWithPassword:password error:&error])
    {
        NSLog(@"Authentificated to XMPP.");
    }
    else
    {
        NSLog(@"Error authentificating to XMPP: %@", [error localizedDescription]);
    }
}

Listen for server response for authentification status:

- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender
{
    NSLog(@"%s", __FUNCTION__);
    XMPPPresence *presence = [XMPPPresence presenceWithType:@"available"];
    [sender sendElement:presence]; 
}

and then try to create XMPPRoom by calling function after authentification success:

- (void)createChatRoom
{    
    // Configure xmppRoom
    XMPPJID *roomJID = [XMPPJID jidWithString:@"[e-mail]"];

    XMPPRoomMemoryStorage *roomMemoryStorage = [[XMPPRoomMemoryStorage alloc] init];

    XMPPRoom *xmppRoom = [[XMPPRoom alloc] initWithRoomStorage:roomMemoryStorage
                                                           jid:roomJID
                                                 dispatchQueue:dispatch_get_main_queue()];

    [xmppRoom activate:self.xmppStream];
    [xmppRoom addDelegate:self delegateQueue:dispatch_get_main_queue()];
    [xmppRoom joinRoomUsingNickname:user history:nil];
}
