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

  1 #import "XMPPFramework.h" 

3、定义下所需属性和方法

 1 @property (nonatomic, strong, readonly) XMPPStream *xmppStream;

 2  

 3 //xmpp自动连接对象，在异常断开后可以尝试自动连接

 4 @property (nonatomic, strong, readonly) XMPPReconnect *xmppReconnect;

 5  

 6 //xmpp中好友列表

 7 @property (nonatomic, strong, readonly) XMPPRoster *xmppRoster;

 8  

 9 //初始化Stream

10 - (void)setupStream;

11  

12 //连接服务器

13 - (BOOL)connect;

14  

15 //断开服务器

16 - (void)disconnect;

17  

18 //登出

19 - (void)logout;

20  

21 //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

22 - (void)goOffline;

23  

24 //获取用户JID

25 - (XMPPJID *) getMyJid;

 

 

4、方法实现，直接帖代码

  1 #import "XMPPManager.h"

  2  

  3 @interface XMPPManager()

  4 @property (nonatomic, strong) NSString *password;

  5 @property (nonatomic, assign) BOOL isXmppConnected;

  6 @property (nonatomic, assign) BOOL isXmppSetuped;

  7 @property (nonatomic, assign) BOOL allowSelfSignedCertificates;

  8 @property (nonatomic, assign) BOOL allowSSLHostNameMismatch;

  9  

 10  

 11 - (void)goOnline;

 12 - (void)goOffline;

 13 @end

 14  

 15 @implementation XMPPManager

 16  

 17 - (void)setupStream {

 18     NSLog(@"xmpp setup");

 19     if (self.isXmppSetuped) {

 20         return;

 21     }

 22      

 23     _xmppStream = [[XMPPStream alloc] init];

 24     _xmppReconnect = [[XMPPReconnect alloc] init];

 25  

 26     // Activate xmpp modules

 27     [_xmppReconnect activate:_xmppStream];

 28     [_xmppReconnect setAutoReconnect:YES];

 29      

 30      

 31     // Add ourself as a delegate to anything we may be interested in

 32     [_xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];

 33     [_xmppReconnect addDelegate:self delegateQueue:dispatch_get_main_queue()];

 34      

 35      

 36     [_xmppStream setHostName:@"192.168.1.209"];

 37      

 38      

 39     [_xmppStream setHostPort:5222];

 40      

 41     // You may need to alter these settings depending on the server you're connecting to

 42      

 43     self.allowSelfSignedCertificates = NO;

 44     self.allowSSLHostNameMismatch = NO;

 45      

 46      

 47 }

 48

 56

 61     }

 62     XMPPPresence *presence = [XMPPPresence presenceWithType:status];

 64      

 65 }

 66  

 67 //下线

217 }

 

 

这个类的逻辑图如下：

 

5、登陆实现

 1 -(IBAction)btnLogin:(id)sender

 2 {

 3     [[NSUserDefaults standardUserDefaults] setObject:self.txtUserName.text forKey:@"jid"];

 4     [[NSUserDefaults standardUserDefaults] setObject:self.txtPassword.text forKey:@"password"];

 5     [[self appDelegate].xmppManager connect];

 6 }

 7  

 8 - (AppDelegate *)appDelegate

 9 {

10     return (AppDelegate *)[UIApplication sharedApplication].delegate;

11 }

 

 

成功连接服务器，并接收到服务器返回的状态信息
