XMPP Series----------user registration and User login features

1. Create a new project

2. Import the XMPP framework

Latest XMPP framework: Https://github.com/robbiehanson/XMPPFramework

Drag several folders of XMPP into the project and the files you need are as follows:

and renamed Sample_xmppframework.h to XMPPFramework.h.

Next, import two dependent libraries: Libresolv.dylib and Libxml2.dylib, and then add header search:

Add a PCH file again

Add the following code to the PCH file:

#ifdef __objc__    #import <UIKit/UIKit.h>    #import "XMPPFramework.h" #endif

Then set the project PCH file

$SRCROOT is followed by the project name/pch file name.

After completing the above steps, the project can be compiled successfully!

Now start building the login interface for the project:

First encapsulate an XMPP tool class: Jkxmpptool

. h file

#import <Foundation/Foundation.h> @interface jkxmpptool:nsobject<xmppstreamdelegate> @property ( Nonatomic, Strong) Xmppstream *xmppstream;//module @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

. m file

#import "JKXMPPTool.h" @implementation jkxmpptoolstatic 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];        The socket connection should know the HOST port and connect [Self.xmppstream Sethostname:kxmpp_host];        [Self.xmppstream Sethostport:kxmpp_port]; Why the AddDelegate? Because Xmppframework uses a large number of multicast proxy multicast-delegate, the agent is generally 1 to 1, but this multicast proxy is a one-to-many, and can add or remove at any time [Self.xmppstream adddelegate:                Self Delegatequeue:dispatch_get_main_queue ()]; Add a function module//1.autoping send a stream:ping if you want to indicate that you are active, you should return a pong _xmppautoping = [[Xmppautoping alloc] init]        ;                All module modules must activate active [_xmppautoping Activate:self.xmppStream]; Autoping because it will periodically send pings, ask the other side to return pong, so this time we need to set [_xmppautoping sETPINGINTERVAL:1000];        It is not just the server that responds; if it is a normal user, it will respond to [_xmppautoping Setrespondstoqueries:yes]; This process is C---->s; observe S--->c (needs to be set on the server)//2.autoreconnect automatically reconnect, when we are disconnected, automatically reconnected up, and the last information automatically added to _x        Mppreconnect = [[Xmppreconnect alloc] init];        [_xmppreconnect Activate:self.xmppStream];    [_xmppreconnect Setautoreconnect:yes]; } return _xmppstream;} -(void) Loginwithjid: (Xmppjid *) JID Andpassword: (NSString *) password{//1.

Then the login function:

The action for the login button is as follows:

#pragma mark-click event/** logon event */-(ibaction) Loginclick: (ID) Sender {    NSString *username = _usernamefield.text;
   nsstring *password = _passwordfield.text;        NSString *message = nil;    if (username.length <= 0) {        message = @ "User name not filled in";    } else if (password.length <= 0) {        message = @ "Password not filled in"; c7/>}        if (Message.length > 0) {        Uialertview *alertview = [[Uialertview alloc] Initwithtitle:nil message: Message Delegate:nil cancelbuttontitle:@ "I Know" otherbuttontitles:nil];        [Alertview show];    } else {[        [jkxmpptool sharedinstance] Loginwithjid:[xmppjid jidwithuser:username domain:@ "im.joker.cn" resource:@ "IOS"] andpassword:password];}    }

returning a successful login message with a notification

-(void) loginsuccess{    NSLog (@ "loginsuccess");        [Self performseguewithidentifier:@ "Loginsegue" sender:self];}

Then realize the function of registering:

-(Ibaction) Registaction: (ID) Sender {nsstring *username = _usernamefield.text;    NSString *password = _passwordfield.text;        NSString *confirm = _confirmfield.text;    NSString *message = nil;    if (username.length <= 0) {message = @ "username not filled in";    } else if (password.length <= 0) {message = @ "Password not filled in";    } else if (confirm.length <= 0) {message = @ "Confirmation password not filled in"; } if (Message.length > 0) {uialertview *alertview = [[Uialertview alloc] Initwithtitle:nil Message:messa        GE Delegate:nil cancelbuttontitle:@ "I Know" otherbuttontitles:nil];    [Alertview show]; } else if (![        Password Isequaltostring:confirm]) {message = @ "Password is inconsistent with confirmation password"; Uialertview *alertview = [[Uialertview alloc] initwithtitle:nil message:message delegate:nil cancelButtonTitle:@ "I know."        Otherbuttontitles:nil];    [Alertview show]; } else {[[Jkxmpptool sharedinstance] Registerwithjid:[xmppjid jidwithuser:username domain:@ ' im.joker.cn ' resource:@ "IOS"] andpassword:password]; }}

Since registration does not require authentication, registration returns BOOL results directly, so the connection Broker method is improved:

This is the successful initialization of the XML stream-(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];}    }
