Objective c 如何在iphone应用程序中实现google聊天

我在网上搜索了很多，但找不到能够帮助我开始google chat实现的实际示例源代码，xmpp框架提供的示例代码也不清楚，因为它有一个Mac桌面应用程序的示例项目

在xmppframework中提供的示例项目（iphoneXmpp）的帮助下，我可以向所有在线/在线/不在线的朋友展示，但它也没有告诉我如何开始聊天

请为我提供任何示例源代码，以便我可以在我的应用程序中初始化谷歌聊天

我真的被卡住了

提前感谢

本教程应该可以做到这一点：

好的，我没有放弃，在研究了xmpp框架的桌面应用程序并尝试将其包含在我的iphone应用程序中后，我找到了一些解决方案

下面是通过gmail向聊天朋友发送信息的代码

-(void)sendMessage
{
messageStr = [NSString stringWithFormat:@"%@",[msgField text] ];
//messageStr = [NSString stringWithString:@"hello ji....."];

BOOL isEmpty = [ self validateIsEmpty:msgField.text];
if([messageStr length] > 0 && isEmpty == NO )
{
    NSXMLElementK *body = [NSXMLElementK elementWithName:@"body"];
    [body setStringValue:messageStr];

    NSXMLElementK *message = [NSXMLElementK elementWithName:@"message"];
    [message addAttributeWithName:@"type" stringValue:@"chat"];
    [message addAttributeWithName:@"to" stringValue:[[user jid] full]];
    [message addChild:body];
            [[self xmppStream ] sendElement:message];
}

在didReceiveMessage中，我有以下代码

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

NSLog(@"---------- xmppStream:didReceiveMessage: ----------");

NSLog(@"--jid---%@", [[user jid] full]);
NSLog(@"--from----%@", [message from]);
//if(![[[user jid] full] isEqual:[message from]]) return;// important when chatting with 2 or more .. and receiving 2 or more messages...

if([message isChatMessageWithBody])
{
    NSString *msg = [[message elementForName:@"body"] stringValue];

    NSLog(@"mmmmmmmmmmssssssgggg-%@",msg);

    [str appendString:[NSString stringWithFormat:@"%@:%@\n\n", [message from], msg]];
    [chatBox setText:str];
}
}

我能够使用这两种方法发送/接收聊天，但问题是，有时我从可用在线联系人（我们可以与之聊天）的表视图中选择的个人id没有收到消息，但任何其他人都会收到消息

好吧，我没有放弃，在研究了xmpp框架的桌面应用程序并试图将其包含在我的iphone应用程序中之后，我找到了一些解决方案

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

    NSString *msg = [[message elementForName:@"body"] stringValue];
    NSString *from = [[message attributeForName:@"from"] stringValue];

    if (msg.length==0) {
        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Receiving Message" 
                                                            message:[NSString stringWithFormat:@"From %@",from]  
                                                           delegate:nil 
                                                  cancelButtonTitle:@"Ok"

这对你来说非常有用，它也会提醒你谁在发送消息，谁想和你聊天，但是我只是被困在我应该在哪里为我登录到iOS SDK的用户实现注销
