问题
I receive messages from a Google Talk account, they are shown in the Table View in the Ios emulator, but when i send it, it is not shown in the Google Talk client (in another computer). This is the code:
-(IBAction)sendchat:(id)sender
{
General *general = [General sharedManager];//It is a singleton class used to store some values that need to be accesible in the whole application.
NSXMLElement *body = [NSXMLElement elementWithName:@"body"];
text=[mensaje text];
NSLog(@"Texto en el body: %@", text);
[body setStringValue:text];
NSArray *dest=[general.firstfrom componentsSeparatedByString:@"/"];//in firstfrom is stored the account from wich we receive the first message. This app cannot start a conversation itself, must only answer
NSLog(@"Destination trimmed: %@", [dest objectAtIndex:0]);//Here, the destination account shows correctly (without the /xxxx stuff, just name@gmail.com)
XMPPMessage *mens=[[XMPPMessage alloc]init];
[mens addAttributeWithName:@"body" stringValue:text];
[mens addAttributeWithName:@"sender" stringValue:general.userlogin];
NSLog(@"text vale: %@", text);
NSXMLElement *messagetosend = [NSXMLElement elementWithName:@"message"];
[messagetosend addAttributeWithName:@"type" stringValue:@"chat"];
[messagetosend addAttributeWithName:@"to" stringValue:[dest objectAtIndex:0]];
[messagetosend addChild:body];
NSLog(@"We are sending to: %@", [dest objectAtIndex:0]);
[self.xmppStream sendElement:messagetosend];
[self xmppStream:xmppStream didReceiveMessage:mens];//manage the sent message as it was received, to show it in the Table View
self.mensaje.text=@"";
}
As I say, messages are received perfectly, but I cannot send. Ive seen plenty of examples of how to send, and they are like my code. If i debug sender it is shown ok (namesender@gmail.com), and the "to" attribute is ok too (namereceiver@gmail.com). The xmppStrem is set correctly (as far as i know):
xmppStream = [[XMPPStream alloc] init];
[xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];
In ViewDidLoad method.
Any help? Thank you.
---EDIT---
I forgot to say, both accounts know each others and in the Google Talk client, the presence is sent.
回答1:
I found the answer. I had two classes receiving messages, because Class A must receive a message to trigger the pushing of the view of the class B (this app is unable to start a chat conversation by itself). So, i set two xmppStream, one for every class. I put an xmppStream in my General class, make both classes take that xmppStream, and it now sends messages.
