[iPhone高级] 基于XMPP的IOS聊天客户端程序
为了方便程序调用，我们把XMPP的一些主要方法写在AppDelegate中
在AppDelegate.m下这几个方法为：
[java]
-(void)setupStream{
//初始化XMPPStream
xmppStream = [[XMPPStream alloc] init];
[xmppStream addDelegate:self delegateQueue:dispatch_get_current_queue()];
}
-(void)goOnline{
//发送在线状态
XMPPPresence *presence = [XMPPPresence presence];
[[self xmppStream] sendElement:presence];
}
-(void)goOffline{
//发送下线状态
XMPPPresence *presence = [XMPPPresence presenceWithType:@"unavailable"];
[[self xmppStream] sendElement:presence];
}
-(BOOL)connect{
[self setupStream];
//从本地取得用户名，密码和服务器地址
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *userId = [defaults stringForKey:USERID];
NSString *pass = [defaults stringForKey:PASS];
NSString *server = [defaults stringForKey:SERVER];
if (![xmppStream isDisconnected]) {
return YES;
}
if (userId == nil || pass == nil) {
return NO;
}
//设置用户
[xmppStream setMyJID:[XMPPJID jidWithString:userId]];
//设置服务器
[xmppStream setHostName:server];
//密码
password = pass;
//连接服务器
NSError *error = nil;
if (![xmppStream connect:&error]) {
NSLog(@"cant connect %@", server);
return NO;
}
return YES;
}
-(void)disconnect{
[self goOffline];
[xmppStream disconnect];
}
-(void)setupStream{
//初始化XMPPStream
xmppStream = [[XMPPStream alloc] init];
[xmppStream addDelegate:self delegateQueue:dispatch_get_current_queue()];
}
-(void)goOnline{
//发送在线状态
XMPPPresence *presence = [XMPPPresence presence];
[[self xmppStream] sendElement:presence];
}
-(void)goOffline{
//发送下线状态
XMPPPresence *presence = [XMPPPresence presenceWithType:@"unavailable"];
[[self xmppStream] sendElement:presence];
}
-(BOOL)connect{
[self setupStream];
//从本地取得用户名，密码和服务器地址
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
NSString *userId = [defaults stringForKey:USERID];
NSString *pass = [defaults stringForKey:PASS];
NSString *server = [defaults stringForKey:SERVER];
if (![xmppStream isDisconnected]) {
return YES;
}
if (userId == nil || pass == nil) {
return NO;
}
//设置用户
[xmppStream setMyJID:[XMPPJID jidWithString:userId]];
//设置服务器
[xmppStream setHostName:server];
//密码
password = pass;
//连接服务器
NSError *error = nil;
if (![xmppStream connect:&error]) {
NSLog(@"cant connect %@", server);
return NO;
}
return YES;
}
-(void)disconnect{
[self goOffline];
[xmppStream disconnect];
}这几个是基础方法，接下来就是XMPPStreamDelegate中的方法，也是接受好友状态，接受消息的重要方法
[java]
//连接服务器
- (void)xmppStreamDidConnect:(XMPPStream *)sender{
isOpen = YES;
NSError *error = nil;
//验证密码
[[self xmppStream] authenticateWithPassword:password error:&error];
}
//验证通过
- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender{
[self goOnline];
}
//收到消息
- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message{
// NSLog(@"message = %@", message);
NSString *msg = [[message elementForName:@"body"] stringValue];
NSString *from = [[message attributeForName:@"from"] stringValue];
NSMutableDictionary *dict = [NSMutableDictionary dictionary];
[dict setObject:msg forKey:@"msg"];
[dict setObject:from forKey:@"sender"];
//消息委托(这个后面讲)
[messageDelegate newMessageReceived:dict];
}
//收到好友状态
- (void)xmppStream:(XMPPStream *)sender didReceivePresence:(XMPPPresence *)presence{
&nbs
