1.创建一个新工程
2.导入XMPP框架
最新的XMPP框架下载地址：https://github.com/robbiehanson/XMPPFramework
将XMPP的几个文件夹拖进工程中，需要的文件如下：
然后把Sample_XMPPFramework.h改名为XMPPFramework.h
接下来导入两个依赖库：libresolv.dylib和libxml2.dylib，然后添加header search：
再添加一个pch文件
在pch文件中添加如下代码：
#ifdef __OBJC__
#import
#import "XMPPFramework.h"
#endif 
$SRCROOT后面是项目名/pch文件名。
做完以上步骤，项目就可以编译成功啦！
现在开始搭建项目的登录界面：
首先封装一个XMPP工具类：JKXMPPTool
.h文件
#import
@interface JKXMPPTool : NSObject
@property (nonatomic, strong) XMPPStream *xmppStream;
// 模块
@property (nonatomic, strong) XMPPAutoPing *xmppAutoPing;
@property (nonatomic, strong) XMPPReconnect *xmppReconnect;
@property (nonatomic, assign) BOOL xmppNeedRegister;
@property (nonatomic, copy) NSString *myPassword;
+ (instancetype)sharedInstance;
- (void)loginWithJID:(XMPPJID *)JID andPassword:(NSString *)password;
- (void)registerWithJID:(XMPPJID *)JID andPassword:(NSString *)password;
@end
#import "JKXMPPTool.h"
@implementation JKXMPPTool
static JKXMPPTool *_instance;
+ (instancetype)sharedInstance
{
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
_instance = [JKXMPPTool new];
});
return _instance;
}
- (XMPPStream *)xmppStream
{
if (!_xmppStream) {
_xmppStream = [[XMPPStream alloc] init];
//socket 连接的时候 要知道host port 然后connect
[self.xmppStream setHostName:kXMPP_HOST];
[self.xmppStream setHostPort:kXMPP_PORT];
//为什么是addDelegate? 因为xmppFramework 大量使用了多播代理multicast-delegate ,代理一般是1对1的，但是这个多播代理是一对多得，而且可以在任意时候添加或者删除
[self.xmppStream addDelegate:self delegateQueue:dispatch_get_main_queue()];
}
return _xmppStream;
}
- (void)loginWithJID:(XMPPJID *)JID andPassword:(NSString *)password
{
// 1.建立TCP连接
// 2.把我自己的jid与这个TCP连接绑定起来（即使匿名登录，依然得设置JID，只是我们可以设置一个任意的JID，例如anonymous@
[self.xmppStream setMyJID:JID];
self.myPassword = password;
self.xmppNeedRegister = NO;
[self.xmppStream connectWithTimeout:XMPPStreamTimeoutNone error:nil];
}
//注册方法里没有调用auth方法
- (void)registerWithJID:(XMPPJID *)JID andPassword:(NSString *)password
{
[self.xmppStream setMyJID:JID];
self.myPassword = password;
self.xmppNeedRegister = YES;
[self.xmppStream connectWithTimeout:XMPPStreamTimeoutNone error:nil];
}
- (void)goOnline
{
// 发送一个
// 我很忙
// xa
//
[presence addChild:[DDXMLNode elementWithName:@"status" stringValue:@"我现在很忙"]];
[presence addChild:[DDXMLNode elementWithName:@"show" stringValue:@"xa"]];
[self.xmppStream sendElement:presence];
}
#pragma mark ===== XMPPStream delegate =======
//socket 连接建立成功
- (void)xmppStream:(XMPPStream *)sender socketDidConnect:(GCDAsyncSocket *)socket
{
NSLog(@"%s",__func__);
}
//这个是xml流初始化成功
- (void)xmppStreamDidConnect:(XMPPStream *)sender
{
NSLog(@"%s",__func__);
//匿名登录 会随机生成一个username和JID，这个是在服务器的内存中随机生成，不会写入服务器的数据表，例如生成的jid为[email protected]/1nv8l4khxg
//为了防止客户端匿名登录,服务器有策略关闭匿名
// [self.xmppStream authenticateAnonymously:nil];
if (self.xmppNeedRegister) {
[self.xmppStream registerWithPassword:self.myPassword error:nil];
} else {
[self.xmppStream authenticateWithPassword:self.myPassword error:nil];
}
}
- (void)xmppStreamDidDisconnect:(XMPPStream *)sender withError:(NSError *)error
{
NSLog(@"%s",__func__);
}
//登录失败
- (void)xmppStream:(XMPPStream *)sender didNotAuthenticate:(DDXMLElement *)error
{
NSLog(@"%s",__func__);
}
//登录成功
- (void)xmppStreamDidAuthenticate:(XMPPStream *)sender
{
NSLog(@"%s",__func__);
[self goOnline];
[[NSNotificationCenter defaultCenter] postNotificationName:kLOGIN_SUCCESS object:nil];
}
@end 然后是登录功能:
登录按钮的action如下：
#pragma mark - click event
/** 登录事件 */
- (IBAction)loginClick:(id)sender {
NSString *username = _usernameField.text;
NSString *password = _passwordField.text;
NSString *message = nil;
if (username.length <= 0) {
message = @"用户名未填写";
} else if (password.length <= 0) {
message = @"密码未填写";
}
if (message.length > 0) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:nil message:message delegate:nil cancelButtonTitle:@"我知道了" otherButtonTitles:nil];
[alertView show];
} else {
[[JKXMPPTool sharedInstance] loginWithJID:[XMPPJID jidWithUser:username domain:@"im.joker.cn" resource:@"iOS"] andPassword:password];
}
}
- (void)loginSuccess
{
NSLog(@"loginSuccess");
[self performSegueWithIdentifier:@"loginSegue" sender:self];
}再然后实现注册的功能：
- (IBAction)registAction:(id)sender {
NSString *username = _usernameField.text;
NSString *password = _passwordField.text;
NSString *confirm = _confirmField.text;
NSString *message = nil;
if (username.length <= 0) {
message = @"用户名未填写";
} else if (password.length <= 0) {
message = @"密码未填写";
} else if (confirm.length <= 0) {
message = @"确认密码未填写";
}
if (message.length > 0) {
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:nil message:message delegate:nil cancelButtonTitle:@"我知道了" otherButtonTitles:nil];
[alertView show];
} else if (![password isEqualToString:confirm]) {
message = @"密码与确认密码不一致";
UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:nil message:message delegate:nil cancelButtonTitle:@"我知道了" otherButtonTitles:nil];
[alertView show];
} else {
[[JKXMPPTool sharedInstance] registerWithJID:[XMPPJID jidWithUser:username domain:@"im.joker.cn" resource:@"iOS"] andPassword:password];
}
}
//这个是xml流初始化成功
- (void)xmppStreamDidConnect:(XMPPStream *)sender
{
NSLog(@"%s",__func__);
if (self.xmppNeedRegister) {
BOOL result = [self.xmppStream registerWithPassword:self.myPassword error:nil];
NSNumber *number = [NSNumber numberWithBool:result];
[[NSNotificationCenter defaultCenter] postNotificationName:kREGIST_RESULT object:number];
} else {
[self.xmppStream authenticateWithPassword:self.myPassword error:nil];
}
