3.课堂上创建过程

打开终端:(1)pod search EaseMob (2)cd + 文件夹的名字 (3) vim Podfile 打开编辑器 (4)pod 'Easemob', '~> 2.1.4’(5)Esc (6)shift+; 输入wq (8) pod update(9)导入 #import <EaseMob.h>

4.创建一个有登陆和注册页的storyBoard

在AppDelegate.m里面写

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    //初始化EaseMob
    [[EaseMobsharedInstance] registerSDKWithAppKey:@"chenkai#bjs151251"apnsCertName:@"push"];
    //启动完成
    [[EaseMobsharedInstance] application:application didFinishLaunchingWithOptions:launchOptions];
   
        //获取LoginAndRegister的Storyboard
    UIStoryboard *loginStoryboard = [UIStoryboardstoryboardWithName:@"LoginAndRegist"bundle:nil];
    //获取Storyboard里面的根视图控制器(模态到初始的Controller)
    UIViewController *loginVC = [loginStoryboard instantiateInitialViewController];
    //让loginStoryboard可见
    [self.windowmakeKeyAndVisible];
    //模态
    [self.window.rootViewControllerpresentViewController:loginVC animated:YEScompletion:nil];
   
    returnYES;

}

 

 

一.注册页面

#import "ViewController.h"

@interface ResistViewController : ViewController
///用户名
@property (weak, nonatomic) IBOutletUITextField *userNameField;
///密码
@property (weak, nonatomic) IBOutletUITextField *passwordField;
///确认密码
@property (weak, nonatomic) IBOutletUITextField *confirmField;
//点击注册的方法

- (IBAction)didClickRegistButtonAction:(UIButton *)sender;}

.m文件

 

#import "ResistViewController.h"

#import <EaseMob.h>
@interfaceResistViewController ()

@end

@implementation ResistViewController

- (void)viewDidLoad {
    [superviewDidLoad];
}
//点击注册的方法
- (IBAction)didClickRegistButtonAction:(UIButton *)sender {
   
    if (self.userNameField.text.length > 0 && self.passwordField.text.length > 0) {
        if ([self.passwordField.textisEqualToString:self.confirmField.text]) {
           
            /*
            //注册的同步方法
            EMError *error = nil;
          BOOL isSuccess =  [[EaseMob sharedInstance].chatManager registerNewAccount:self.userNameField.text password:self.passwordField.text error:&error];
            if (!isSuccess) {
                NSLog(@"注册成功");
            }
             */
           
            //异步的注册方法(这里和同步的区别就是不用布尔值接收,用error)
             [[EaseMobsharedInstance].chatManagerasyncRegisterNewAccount:self.userNameField.text  password:self.passwordField.textwithCompletion:^(NSString *username, NSString *password, EMError *error) {
                if (!error) {
                    NSLog(@"注册成功");
                }
            } onQueue:dispatch_get_main_queue() ];
           
        }

    }

二.登陆了页面

 

#import "LoginViewController.h"
#import <EaseMob.h>
@interfaceLoginViewController ()
///用户名
@property (weak, nonatomic) IBOutletUITextField *userNameField;
///密码
@property (weak, nonatomic) IBOutletUITextField *passworkField;

//登录按钮的点击方法
- (IBAction)didClickLoginButtonAction:(UIButton *)sender;

@end

@implementation LoginViewController

- (void)viewDidLoad {
    [superviewDidLoad];
}

//登陆的按钮的点击方法
- (IBAction)didClickLoginButtonAction:(UIButton *)sender {
  
    //判断
    if (self.userNameField.text.length > 0 && self.passworkField.text.length > 0) {
        //这里这里要设置infor.plist设置请求才可以登陆成功
         /*
           //同步的block方法
       EMError *error = nil;
        NSDictionary *loginInfo = [[EaseMob sharedInstance].chatManager loginWithUsername:self.userNameField.text password:self.passworkField.text error:&error ];
        if (!error&&loginInfo) {
            NSLog(@"登陆成功");
          //登陆成功返回好友页面
          [self dismissViewControllerAnimated:YES completion:nil];
        }
          */
         //异步的block方法
        [[EaseMobsharedInstance].chatManagerasyncLoginWithUsername:self.userNameField.text  password:self.passworkField.textcompletion:^(NSDictionary *loginInfo, EMError *error) {
            if (!error) {
               NSLog(@"登陆成功");
            }
        } onQueue:dispatch_get_main_queue() ];
       
        //登陆成功返回好友页面
        [selfdismissViewControllerAnimated:YEScompletion:nil];
    }
   
}

@end

 

三.好友列表页面

#import "RosterTableController.h"
#import <EaseMob.h>
#import "ChatTableController.h"
@interfaceRosterTableController ()<IChatManagerDelegate>

///好友列表的属性
@property(nonatomic,strong)NSMutableArray *rosterArray;

@end

@implementation RosterTableController

//获取好友列表
- (void)reloadAllRosters{
    EMError *error = nil;
    NSArray *rosters = [[EaseMobsharedInstance].chatManagerfetchBuddyListWithError:&error];
    if (!error) {
        [self.rosterArrayremoveAllObjects];
        [self.rosterArrayaddObjectsFromArray:rosters];
        //刷新tableView
        [self.tableViewreloadData];
        NSLog(@"获取成功 -- %@",rosters);
    }
}

- (void)viewDidAppear:(BOOL)animated{
    [superviewDidAppear:animated];
    //刷新好友列表
    [selfreloadAllRosters];
}

- (void)viewDidLoad {
    [superviewDidLoad];
    //初始化好友数组
    self.rosterArray = [NSMutableArraynew];
   
    [selfreloadAllRosters];
   
    //添加代理
    [[EaseMobsharedInstance].chatManageraddDelegate:selfdelegateQueue:dispatch_get_main_queue()];
}

- (void)didReceiveMemoryWarning {
    [superdidReceiveMemoryWarning];
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    returnself.rosterArray.count;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Roster"forIndexPath:indexPath];
    EMBuddy *roster = self.rosterArray[indexPath.row];
    cell.textLabel.text = roster.username;
   
    return cell;
}

- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
   
    returnYES;
}


- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
    if (editingStyle == UITableViewCellEditingStyleDelete) {
      
        //删除好友
        EMBuddy *buddy = self.rosterArray[indexPath.row];
        EMError *error = nil;
        //removeFromRemote:是否从对方的好友删除        [[EaseMobsharedInstance].chatManagerremoveBuddy:buddy.usernameremoveFromRemote:YESerror:&error ];                //从数组删除        [self.rosterArrayremoveObject:buddy];        if (!error) {            NSLog(@"删除成功");        }               //先删除数据再操作UI         [tableView deleteRowsAtIndexPaths:@[indexPath]withRowAnimation:UITableViewRowAnimationFade];    } elseif (editingStyle == UITableViewCellEditingStyleInsert) {           }  }- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {    if ([segue.identifierisEqualToString:@"Chat"]) {        //传值        //选中的行数        NSIndexPath *indexPath = [self.tableViewindexPathForSelectedRow];        EMBuddy *buddy = self.rosterArray[indexPath.row];        ChatTableController *chatTC = [segue destinationViewController];        chatTC.buddy = buddy;    }}//接收到好友请求- (void)didReceiveBuddyRequest:(NSString *)username message:(NSString *)message{       UIAlertController *alertC = [UIAlertControlleralertControllerWithTitle:@"好友请求"message:message preferredStyle:(UIAlertControllerStyleAlert)];    //接收好友    UIAlertAction *accept = [UIAlertActionactionWithTitle:@"接收"style:(UIAlertActionStyleDefault) handler:^(UIAlertAction * _Nonnull action) {        EMError *error = nil;       BOOL success = [[EaseMobsharedInstance] .chatManageracceptBuddyRequest:username error:&error];        if (!error && success) {            NSLog(@"接收好友请求");        }    }];    [alertC addAction:accept];    //拒绝好友    UIAlertAction *refuse = [UIAlertActionactionWithTitle:@"拒绝"style:(UIAlertActionStyleDefault) handler:^(UIAlertAction * _Nonnull action) {        EMError *error = nil;        BOOL success = [[EaseMobsharedInstance].chatManagerrejectBuddyRequest:username reason:@"不是人类"error:&error ];        if (!error && success) {            NSLog(@"拒绝好友请求");        }    }];    [alertC addAction:refuse];

    //模态

    [selfpresentViewController:alertC animated:YEScompletion:nil];

}

四.添加好友界面

#import "AddViewController.h"
#import <EaseMob.h>
@interfaceAddViewController ()
///好友的用户名
@property (weak, nonatomic) IBOutletUITextField *userNameField;

- (IBAction)didClickAddBUttonAction:(UIButton *)sender;

@end

@implementation AddViewController

- (void)viewDidLoad {
    [superviewDidLoad];
}

//点击添加按钮的方法
- (IBAction)didClickAddBUttonAction:(UIButton *)sender {
   
    if (self.userNameField.text.length > 0) {
        //添加好友
        EMError *error = nil;
        BOOL isSuccess = [[EaseMobsharedInstance].chatManageraddBuddy:self.userNameField.textmessage:@"我想加你为好友"error:&error ];
        if (!error && isSuccess) {
            NSLog(@"发送好友请求成功");
        }
    }
   

}

五.聊天页面

.h文件

#import <UIKit/UIKit.h>
#import <EaseMob.h>

@interface ChatTableController : UITableViewController

///会话的TextField
@property (weak, nonatomic) IBOutletUITextField *chatField;

///好友属性
@property(nonatomic,strong)EMBuddy *buddy;

.m文件  这里需要用到一个类

#import "ChatTableController.h"
#import "MessageBody.h"
@interfaceChatTableController ()<IChatManagerDelegate>

///消息列表
@property(nonatomic,strong)NSMutableArray *messageArray;
//发送消息
- (IBAction)sendMessage:(UIBarButtonItem *)sender;

@end

@implementation ChatTableController

- (void)viewDidLoad {
    [superviewDidLoad];
   
    self.messageArray = [NSMutableArraynew];
   
    EMConversation *conversation = [[EaseMobsharedInstance].chatManagerconversationForChatter:self.buddy.usernameconversationType:eConversationTypeChat ];
    //接收消息代理执行
    conversation.enableUnreadMessagesCountEvent = YES;
    //添加代理队列
    [[EaseMobsharedInstance].chatManageraddDelegate:selfdelegateQueue:dispatch_get_main_queue()];
    //展示标题
    self.title = self.buddy.username;
   
   
    }

- (void)didReceiveMemoryWarning {
    [superdidReceiveMemoryWarning];
}


- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    return1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    returnself.messageArray.count;
}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Chat"forIndexPath:indexPath];
    EMMessage *message = self.messageArray[indexPath.row];
    if ([message.toisEqualToString:self.buddy.username]) {
        cell.textLabel.text = @"";
        MessageBody *body = message.messageBodies[0];
        //字符 对象
        EMChatText *textBody = [body chatObject];
        cell.detailTextLabel.text = textBody.text;
    }else{
        MessageBody *body = message.messageBodies[0];
        //字符 对象
        EMChatText *textBody = [body chatObject];
        cell.textLabel.text = textBody.text;
        cell.detailTextLabel.text = @"";
    }
   
    return cell;}//刷新消息记录- (void)reloadAllMessages{    //通过两人的会话取聊天记录    EMConversation *conversation = [[EaseMobsharedInstance].chatManagerconversationForChatter:self.buddy.usernameconversationType:eConversationTypeChat];    NSArray *messages = [conversation loadAllMessages];       if (messages.count > 0) {        [self.messageArrayremoveAllObjects];        [self.messageArrayaddObjectsFromArray:messages];               //滚动到最后一条        NSIndexPath *indexPath = [NSIndexPathindexPathForRow:self.messageArray.count - 1inSection:0];        //刷新tableView        [self.tableViewreloadData];        [self.tableViewscrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionBottomanimated:YES];    }}//接收到消息- (void)didReceiveMessage:(EMMessage *)message{    NSLog(@"接收到消息");    [selfreloadAllMessages];}//接收离线消息- (void)didReceiveOfflineMessages:(NSArray *)offlineMessages{    NSLog(@"接收离线消息");    [selfreloadAllMessages];}//将要发送消息- (void)willSendMessage:(EMMessage *)message error:(EMError *)error{    NSLog(@"将要发送消息");}//消息发送成功- (void)didSendMessage:(EMMessage *)message error:(EMError *)error{    NSLog(@"消息发送成功");    [selfreloadAllMessages];}- (IBAction)sendMessage:(UIBarButtonItem *)sender {    //创建文本消息    EMChatText *chatText = [[EMChatTextalloc] initWithText:self.chatField.text];    /*     这是错误的//    //创建MessageBody//    MessageBody *body = [[MessageBody alloc] initWithChatObject:chatText];//    body.messageBodyType = eMessageBodyType_Text;    */    EMTextMessageBody *body = [[EMTextMessageBodyalloc]initWithChatObject:chatText];    //创建message对象    EMMessage *message = [[EMMessagealloc] initWithReceiver:self.buddy.usernamebodies:@[body]];    EMError *error = nil;    [[EaseMobsharedInstance].chatManagersendMessage:message progress:nilerror:&error];    if (!error) {        NSLog(@"消息发送成功");        [selfreloadAllMessages];    } }

@end

六.创建的类

.h文件

#import <Foundation/Foundation.h>
#import <EaseMob.h>

@interface MessageBody : NSObject<IEMMessageBody>

@property (nonatomic, assign) MessageBodyType messageBodyType;

@property (nonatomic, strong, readonly) id<IEMChatObject> chatObject;

@property (nonatomic, weak) EMMessage *message;

- (id)initWithChatObject:(id<IEMChatObject>)aChatObject;

@end

.m文件(这里是因为签订了协议必须实现这个方法)

#import "MessageBody.h"
@implementation MessageBody

- (id)initWithChatObject:(id<IEMChatObject>)aChatObject{
    returnnil;
}

@end
