iOS 环信3.0 简单单聊集成

1、准备工作，配置证书，绑定APPID，。注意开发证书和生产证书。创建应用，上传p12 文件（证书）到环信后台，环信会返回一个应用标识就是APPKEY，以及你的推送证书的名字。

2、下载官方SDK，

3、新建个工程，把上面的 HyphenateFullSDK拖到工程里，开始配置。

• 设置bitcode 为 No；
• 创建pch ，

#ifdef __OBJC__

#import 
#import 
#define HUANXINAPPKEY @"1198170313178186#lxchatdemo"  //应用标识
#define APNSNAME @"LXChatDemo" //证明名字
#endif

配置依赖的静态库：

CoreMedia.framework
AudioToolbox.framework
AVFoundation.framework
MobileCoreServices.framework
ImageIO.framework
libc++.dylib
libz.dylib
libstdc++.6.0.9.dylib
libsqlite3.dylib
libiconv.dylib

如果编译出现这样的问题：

dyld: Library not loaded: @rpath/Hyphenate.framework/Hyphenate
  Referenced from: /Users/liangyi/Library/Developer/CoreSimulator/Devices/F3F0CB24-F891-489D-B71F-1AA6DA17832C/data/Containers/Bundle/Application/8D4D4F2E-A19F-4590-BE80-41403C735448/EMDemo.app/EMDemo
  Reason: image not found

//字面意思是嵌入二进制文件

最后编译command + B 通过即可。

4、根据官方视频简单实现单聊：

EMOptions 是SDK的设置选项
EMClient 是用户选项，大概看一下头文件，基本上包含了单聊，群聊，聊天室：

@property (nonatomic, strong, readonly) id chatManager;

/*!
 *  \~chinese 
 *  好友模块
 *
 *  \~english 
 *  Contact Management
 */
@property (nonatomic, strong, readonly) id contactManager;

/*!
 *  \~chinese 
 *  群组模块
 *
 *  \~english 
 *  Group Management
 */
@property (nonatomic, strong, readonly) id groupManager;

/*!
 *  \~chinese 
 *  聊天室模块
 *
 *  \~english 
 *  Chat room Management
 */
@property (nonatomic, strong, readonly) id roomManager;

直接按照视频实现下

#import "AppDelegate.h"
#import "ChatViewController.h"
@interface AppDelegate ()

@end

@implementation AppDelegate


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    
    EMOptions *option =[EMOptions optionsWithAppkey:HUANXINAPPKEY];
    option.apnsCertName = APNSNAME;
    
    EMError *error =[[EMClient sharedClient]initializeSDKWithOptions:option];
    if (!error) {
        NSLog(@"初始化成功");
    }
    error = [[EMClient sharedClient] registerWithUsername:@"111" password:@"111"];
    if (!error) {
        NSLog(@"注册成功");
    }else{
        NSLog(@"%@",error.errorDescription);
    }
    error = [[EMClient sharedClient] registerWithUsername:@"222" password:@"222"];
    if (!error) {
        NSLog(@"注册成功");
    }else{
        NSLog(@"%@",error.errorDescription);
    }
    
    error =[[EMClient sharedClient]loginWithUsername:@"111" password:@"111"];
    if (!error) {
        NSLog(@"登录成功");
    }else{
        NSLog(@"%@",error.errorDescription);
    }
//    error =[[EMClient sharedClient]loginWithUsername:@"222" password:@"222"];
//    if (!error) {
//        NSLog(@"登录成功");
//    }else{
//        NSLog(@"%@",error.errorDescription);
//    }
    
    self.window =[[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];
    ChatViewController *vc =[[ChatViewController alloc]initWithConversationId:@"222" conversationType:EMConversationTypeChat];
    UINavigationController *nav =[[UINavigationController alloc]initWithRootViewController:vc];
    self.window.rootViewController = nav;
    [self.window makeKeyAndVisible];
    return YES;
}

//接受消息 必须ChatManager 的代理
@interface ChatViewController ()
@property (weak, nonatomic) IBOutlet UITextField *input;
@property(nonatomic,strong)EMConversation *conversation;
@property (weak, nonatomic) IBOutlet UILabel *receiveLabel;

@end

@implementation ChatViewController
-(id)initWithConversationId:(NSString *)conversation conversationType:(EMConversationType)conversationType{
    self = [super initWithNibName:@"ChatViewController" bundle:nil];
    if (self) {
        self.conversation = [[EMClient sharedClient].chatManager getConversation:conversation type:conversationType createIfNotExist:YES];
        [[EMClient sharedClient].chatManager addDelegate:self delegateQueue:nil];
        
    }
    return self;
}
-(void)dealloc{
    [[EMClient sharedClient] removeDelegate:self];
}
- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
}
#pragma mark --接受消息---
-(void)messagesDidReceive:(NSArray *)aMessages{
    EMMessage *message = aMessages[0];
    EMTextMessageBody *body = (EMTextMessageBody *)message.body;
    self.receiveLabel.text = body.text;
}
#pragma mark ---发送消息---
- (IBAction)sendAction:(id)sender {
    EMTextMessageBody *body =[[EMTextMessageBody alloc]initWithText:self.input.text];
    EMMessage *message =[[EMMessage alloc]initWithConversationID:self.conversation.conversationId from:[EMClient sharedClient].currentUsername to:self.conversation.conversationId body:body ext:nil];
    [[EMClient sharedClient].chatManager sendMessage:message progress:^(int progress) {
       
    } completion:^(EMMessage *message, EMError *error) {
        if (!error) {
            NSLog(@"发送成功");
        }else{
            NSLog(@"%@",error.errorDescription);
        }
    }];
}

最后别忘了：

NSAppTransportSecurity
    
        NSAllowsArbitraryLoads
        
    

简单单聊集成就是这样了。至于消息的存储，排序，提示，还需要借助数据库，推送进行处理，当然也可以使用环信的数据库。
最简单的集成单聊页面，就是把EaseUI 拖到项目里，然后定义一个UIViewController继承与EaseMessageViewController即可：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    
    EMOptions *option =[EMOptions optionsWithAppkey:HUANXINAPPKEY];
    option.apnsCertName = APNSNAME;
    
    EMError *error =[[EMClient sharedClient]initializeSDKWithOptions:option];
    if (!error) {
        NSLog(@"初始化成功");
    }
    
    error =[[EMClient sharedClient]loginWithUsername:@"111" password:@"111"];
    if (!error) {
        NSLog(@"登录成功");
    }else{
        NSLog(@"%@",error.errorDescription);
    }

    
    self.window =[[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];
    ChatViewController *vc =[[ChatViewController alloc]initWithConversationChatter:@"222" conversationType:EMConversationTypeChat];
                             UINavigationController *nav =[[UINavigationController alloc]initWithRootViewController:vc];
    self.window.rootViewController = nav;
    [self.window makeKeyAndVisible];
    return YES;
}

然后就可以实现简单的单聊了，环信官方建议好友体系由自己管理，当然开发环境环信也提供了好友体系。
