XMPPFramework-IOS开发（二）登陆以及自定义类

XMPPFramework自带的例子，很不适合正式的应用环境，所以在登陆之前，我们先把xmpp相关操作提取出来，写成一个单独的类来进行管理操作

先介绍下XMPPFramework里面常用的类

XMPPStream：xmpp基础服务类

XMPPRoster：好友列表类

XMPPRosterCoreDataStorage：好友列表（用户账号）在core data中的操作类

XMPPvCardCoreDataStorage：好友名片（昵称，签名，性别，年龄等信息）在core data中的操作类

XMPPvCardTemp：好友名片实体类，从数据库里取出来的都是它

XMPPvCardAvatarModule：好友头像

XMPPReconnect：如果失去连接,自动重连

XMPPRoom：提供多用户聊天支持

XMPPPubSub：发布订阅

1、新建一个XMPPManager类

2、引入头文件

 #import "XMPPFramework.h" 

3、定义下所需属性和方法

@property (nonatomic, strong, readonly) XMPPStream *xmppStream;
 
//xmpp自动连接对象，在异常断开后可以尝试自动连接
@property (nonatomic, strong, readonly) XMPPReconnect *xmppReconnect;
 
//xmpp中好友列表
@property (nonatomic, strong, readonly) XMPPRoster *xmppRoster;
 
//初始化Stream
- (void)setupStream;
 
//连接服务器
- (BOOL)connect;
 
//断开服务器
- (void)disconnect;
 
//登出
- (void)logout;
 
//下线，此处下线是指发消息给服务器，变更下自己的状态，而不是断开socket连接
- (void)goOffline;
 
//获取用户JID
- (XMPPJID *) getMyJid;

 

4、方法实现，直接帖代码

#import "XMPPManager.h"
 
@interface XMPPManager()
@property (nonatomic, strong) NSString *password;
@property (nonatomic, assign) BOOL isXmppConnected;
@property (nonatomic, assign) BOOL isXmppSetuped;
@property (nonatomic, assign) BOOL allowSelfSignedCertificates;
@property (nonatomic, assign) BOOL allowSSLHostNameMismatch;
 
 
- (void)goOnline;
- (void)goOffline;
@end
 
@implementation XMPPManager
 
- (void)setupStream {
    NSLog(@"xmpp setup");
    if (self.isXmppSetuped) {
        return;
    }
     
    _xmppStream = [[XMPPStream alloc] init];
    _xmppReconnect = [[XMPPReconnect alloc] init];
 
    // Activate xmpp modules
    [_xmppReconnect activate:_xmppStream];
    [_xmppReconnect setAutoReconnect:YES];
     
     
    // Add ourself as a delegate to anything we may be interested in
    [_xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];
    [_xmppReconnect addDelegate:self delegateQueue:dispatch_get_main_queue()];
     
     
    [_xmppStream setHostName:@"192.168.1.209"];
     
     
    [_xmppStream setHostPort:5222];
     
    // You may need to alter these settings depending on the server you're connecting to
     
    self.allowSelfSignedCertificates = NO;
    self.allowSSLHostNameMismatch = NO;
     
     
}
 
-(XMPPJID *) getMyJid
{
    return [self.xmppStream myJID];
}
 
- (void)goOnline {
    NSLog(@"xmpp goOnline");
     
    // 上传自己的在线状态
    NSString *status=[[NSUserDefaults standardUserDefaults] stringForKey:@"status"];
    if (!status) {
        status=@"available";
    }
    XMPPPresence *presence = [XMPPPresence presenceWithType:status];
    [[self xmppStream] sendElement:presence];
     
}
 
//下线
- (void)goOffline {
    XMPPPresence *presence = [XMPPPresence presenceWithType:@"unavailable"];
    [[self xmppStream] sendElement:presence];
}
 
- (BOOL)connect {
    //[self setupStream];
    NSLog(@"xmpp connect");
     
    NSString *jabberID = [[NSUserDefaults standardUserDefaults] objectForKey:@"jid"];
    NSString *myPassword = [[NSUserDefaults standardUserDefaults] objectForKey:@"password"];
     
    if (![self.xmppStream isDisconnected]) {
        return YES;
    }
     
    if (jabberID == nil || myPassword == nil) {
        return NO;
    }
     
    [self.xmppStream setMyJID:[XMPPJID jidWithString:jabberID]];
    self.password = myPassword;
    NSError *error = nil;
     
    if (![self.xmppStream connectWithTimeout:XMPPStreamTimeoutNone error:&error])
    {
        NSLog(@"Error connecting: %@", error);
         
        return NO;
    }
    return YES;
}
 
//登出
- (void)logout{
    [self disconnect];
    [self teardownStream];
}
 
- (void)disconnect {
     
    NSLog(@"xmpp disconnect");
     
    [self goOffline];
    [_xmppStream disconnect];
}
 
- (void)teardownStream
{
    [_xmppStream removeDelegate:self];
     
    [_xmppReconnect deactivate];
     
    [_xmppStream disconnect];
     
    _xmppStream = nil;
    _xmppReconnect = nil;
 
    self.isXmppSetuped = NO;
    self.isXmppConnected = NO;
    self.isAccessibilityElement = NO;
     
}
 
- (void)xmppStream:(XMPPStream *)sender socketDidConnect:(GCDAsyncSocket *)socket
{
    NSLog(@"socket connect");
}
 
- (void)xmppStream:(XMPPStream *)sender willSecureWithSettings:(NSMutableDictionary *)settings
{
     
    if (self.allowSelfSignedCertificates)
    {
        [settings setObject:[NSNumber numberWithBool:YES] forKey:(NSString *)kCFStreamSSLAllowsAnyRoot];
    }
     
    if (self.allowSSLHostNameMismatch)
    {
        [settings setObject:[NSNull null] forKey:(NSString *)kCFStreamSSLPeerName];
    }
    else
    {
        NSString *expectedCertName = nil;
         
        NSString *serverDomain = _xmppStream.hostName;
        NSString *virtualDomain = [_xmppStream.myJID domain];
         
        if (serverDomain == nil)
        {
            expectedCertName = virtualDomain;
        }
        else
        {
            expectedCertName = serverDomain;
        }
         
        if (expectedCertName)
        {
            [settings setObject:expectedCertName forKey:(NSString *)kCFStreamSSLPeerName];
        }
    }
}
 
- (void)xmppStreamDidConnect:(XMPPStream *)sender {
    NSLog(@"xmpp xmppStreamDidConnect");
    NSError *error = nil;
     
     
    [[self xmppStream] authenticateWithPassword:self.password error:&error];
}
 
- (void)xmppStreamDidDisconnect:(XMPPStream *)sender withError:(NSError *)error
{
    NSLog(@"xmppStreamDidDisconnect with error:%@",error);
    //[[self appDelegate] hideHUD];
}
 
- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender {
    NSLog(@"xmpp xmppStreamDidAuthenticate");
     
    [self goOnline];
}
 
- (void)xmppStream:(XMPPStream *)sender didNotAuthenticate:(NSXMLElement *)error
{
    NSLog(@"xmpp didNotAuthenticate error--%@",error);
     
}
 
- (void)xmppStream:(XMPPStream *)sender didReceiveMessage:(XMPPMessage *)message {
     
    NSLog(@"Received message: %@",message);
}
 
- (void)xmppStream:(XMPPStream *)sender didReceivePresence:(XMPPPresence *)presence {
    NSLog(@"--> %@", presence);
}
 
- (void)xmppStream:(XMPPStream *)sender didReceiveError:(id)error
{
    NSLog(@"Did Receive Error!");
}
 
- (BOOL)xmppStream:(XMPPStream *)sender didReceiveIQ:(XMPPIQ *)iq
{
    NSLog(@"did ReceiveIQ");
    NSLog(@"ReceiveIQ:%@",iq);
    return NO;
}

 

这个类的逻辑图如下：

5、登陆实现

-(IBAction)btnLogin:(id)sender
{
    [[NSUserDefaults standardUserDefaults] setObject:self.txtUserName.text forKey:@"jid"];
    [[NSUserDefaults standardUserDefaults] setObject:self.txtPassword.text forKey:@"password"];
    [[self appDelegate].xmppManager connect];
}
 
- (AppDelegate *)appDelegate
{
    return (AppDelegate *)[UIApplication sharedApplication].delegate;
}

 

成功连接服务器，并接收到服务器返回的状态信息
