アプリにxmppを統合し、すべてのユーザーをテーブルビューに一覧表示できるようにしましたが、オンラインユーザーのみを表示してから、オンラインの友達にメッセージを送受信する機能を実装したいと考えています...
役立つコードを教えてください...
これが私のコードで、Facebookのログイン後に実行されます。
- (void)fbDidLogin
{
NSLog(@"logged in.....................");
[appDelegate.facebook requestWithGraphPath:@"me" andDelegate:self];
DDLogVerbose(@"%s accessToken: %@ expirationDate: %@",__PRETTY_FUNCTION__,appDelegate.facebook.accessToken,appDelegate.facebook.expirationDate);
self.accessToken = appDelegate.facebook.accessToken;
if (xmppStreamFB) {
[xmppStreamFB release];
xmppStreamFB = nil;
}
xmppStreamFB = [[XMPPStreamFacebook alloc] init];
xmpReconnect = [[XMPPReconnect alloc] initWithStream:xmppStreamFB];
if (xmppRosterStorage) {
[xmppRosterStorage release];
xmppRosterStorage = nil;
}
xmppRosterStorage = [[XMPPRosterCoreDataStorage alloc] init];
if (xmppRoster) {
[xmppRoster release];
xmppRoster = nil;
}
xmppRoster = [[XMPPRoster alloc] initWithStream:xmppStreamFB rosterStorage:xmppRosterStorage];
[xmppStreamFB addDelegate:self];
[xmppRoster addDelegate:self];
[xmppRoster setAutoRoster:YES];
xmppStreamFB.myJID = [XMPPJID jidWithString:[NSString stringWithFormat:@"%@@chat.facebook.com", uid]];
// You may need to alter these settings depending on the server you're connecting to
allowSelfSignedCertificates = NO;
allowSSLHostNameMismatch = YES;
// Uncomment me when the proper information has been entered above.
NSError *error = nil;
if (![xmppStreamFB connect:&error])
NSLog(@"Error connecting: %@", error);
if(!tableView)
{
tableView = [[UITableView alloc]initWithFrame:CGRectMake(0,0, 480, 320) style:UITableViewStylePlain];
}
[tableView setFrame:CGRectMake(0,0, 480, 320)];
[tableView setTag:2];
[tableView setDelegate:self];
[tableView setDataSource:self];
[tableView setHidden:NO];
[tableView setBackgroundColor:[UIColor clearColor]];
[tableView setSeparatorStyle:UITableViewCellSeparatorStyleSingleLine];
[tableView setAlpha:1.0];
[self.view addSubview:tableView];
[self.tableView reloadData];
[self showTopBar];
}
ユーザーをオンラインで表示し、チャット機能を実装するためのxmppフレームワークの実際のフローがわかりません...
i have the following delegate methods as well..
- (void)xmppStreamDidSecure:(XMPPStreamFacebook *)sender
{
NSLog(@"---------- xmppStreamDidSecure: ----------");
}
- (void)xmppStreamDidConnect:(XMPPStreamFacebook *)sender
{
NSLog(@"---------- xmppStreamDidConnect: ----------");
isOpen = YES;
NSError *error = nil;
if (![self.xmppStreamFB authenticateWithAppId:_APP_ID accessToken:self.accessToken error:&error])
{
NSLog(@"Error authenticating: %@", error);
}
else {
NSLog(@"NO Error authenticating:");
/*
ChatViewController *cvc = [[ChatViewController alloc] init];
[self.view addSubview:cvc.view];*/
}
}
- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender
{
NSLog(@"---------- xmppStreamDidAuthenticate: ----------");
[self goOnline];
}
- (void)xmppStream:(XMPPStream *)sender didNotAuthenticate:(NSXMLElement *)error
{
NSLog(@"---------- xmppStream:didNotAuthenticate: ----------");
}
- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq
{
NSLog(@"---------- xmppStream:didReceiveIQ: ----------");
/*
ChatViewController *cvc = [[ChatViewController alloc] init];
[self.view addSubview:cvc.view];*/
return NO;
}
- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message
{
NSLog(@"---------- xmppStream:didReceiveMessage: ----------");
}
- (void)xmppStream:(XMPPStream *)sender didReceivePresence:(XMPPPresence *)presence
{
NSLog(@"---------- xmppStream:didReceivePresence: ----------");
}
- (void)xmppStream:(XMPPStream *)sender didReceiveError:(id)error
{
NSLog(@"---------- xmppStream:didReceiveError: ----------");
}
- (void)xmppStreamDidDisconnect:(XMPPStream *)sender
{
NSLog(@"---------- xmppStreamDidDisconnect: ----------");
if (!isOpen)
{
NSLog(@"Unable to connect to server. Check xmppStream.hostName");
}
}
そして、オンラインとオフラインのユーザープレゼンスのための2つの方法ですが、私のタスクのためにそれらを変更する方法がわかりません。
- (void)goOnline
{
NSXMLElement *presence = [NSXMLElement elementWithName:@"presence"];
[[self xmppStream] sendElement:presence];
}
- (void)goOffline
{
NSXMLElement *presence = [NSXMLElement elementWithName:@"presence"];
[presence addAttributeWithName:@"type" stringValue:@"unavailable"];
[[self xmppStream] sendElement:presence];
}
