资源创建者：
(void)parseNodeAsMap:(XMPPElement*)message
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
if ([[message name] isEqualToString:@"presence"]) {
// NSLog(@"presence--%@--%@",[message attributeStringValueForName:@"type"],[message from].resource);
if ([[message attributeStringValueForName:@"type"] isEqualToString:@"unavailable"]) {
[[NSNotificationCenter defaultCenter] postNotificationName:@"VedioChatUserStatusNoti" object:[message from].resource userInfo:[NSDictionary dictionaryWithObject:@"0" forKey:@"key"]];
}else {
[[NSNotificationCenter defaultCenter] postNotificationName:@"VedioChatUserStatusNoti" object:[message from].resource userInfo:nil];
}
}else if([[message name] isEqualToString:@"message"]) {
if ([[message elementForName:@"body"] stringValue].length<1) {
[[NSNotificationCenter defaultCenter] postNotificationName:@"VedioChatMsgNoti" object:@"...." userInfo:nil];
}else {
// NSLog(@"message--%@",[[message elementForName:@"body"] stringValue]);
[[NSNotificationCenter defaultCenter] postNotificationName:@"VedioChatMsgNoti" object:[[message elementForName:@"body"] stringValue] userInfo:nil];
}
}else {
}
message = nil;
[pool drain];
}
并在此使用：`#pragma mark NOTI
(void)getChatUserStatus:(NSNotification*)noti{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
NSArray *user = [[noti object]componentsSeparatedByString:@"@userid"];
if (user.count<2)
{
RoomUser _ru = {_ru.p_id = userId,_ru.nickName = [[user objectAtIndex:0] copy],_ru.role = @"0"};
[_listDic setObject:[NSValue valueWithBytes:&_ru objCType:@encode(RoomUser)] forKey:userId];
int insertIndex = 0;
...
[_listKeys insertObject:userId atIndex:insertIndex];
onlineUserNum++;
}else {
RoomUser _ru = {_ru.p_id = [[user objectAtIndex:1] copy],_ru.nickName = [[user objectAtIndex:0] copy],_ru.role = [[user objectAtIndex:2] copy]};
if (![noti userInfo]) {
[_listDic setObject:[NSValue valueWithBytes:&_ru objCType:@encode(RoomUser)] forKey:[user objectAtIndex:1]];
int insertIndex = 0;
...
[_listKeys insertObject:_ru.p_id atIndex:insertIndex];
onlineUserNum++;
}else {
[_listKeys removeObject:_ru.p_id];
[_listDic removeObjectForKey:_ru.p_id];
onlineUserNum--;
}
}
//设置第一个标题的 内容
[(UIButton*)[titlesView viewWithTag:1] setTitle:[NSString stringWithFormat:@"%@ %d",[_titles objectAtIndex:0],onlineUserNum] forState:UIControlStateNormal];
user = nil;
[pool drain];
}
