1.配置证书

2.导入SDK

3.快速集成

3.1 在delegate 配置 Appkey 初初始化 chatManager

#import "AppDelegate.h"
//Lite版本
#import 
@interface AppDelegate ()

@end

@implementation AppDelegate


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    
    //AppKey:注册的AppKey，详细见下面注释。
    //apnsCertName:推送证书名（不需要加后缀），详细见下面注释。
    EMOptions *options = [EMOptions optionsWithAppkey:@"vgios#xmg1chat"];
    options.apnsCertName = nil;
    [[EMClient sharedClient] initializeSDKWithOptions:options];
    
    
    // 写个nil 默认代理会在主线程调用
    [[EMClient sharedClient].chatManager addDelegate:self delegateQueue:nil];
    return YES;
}


#pragma mark 自动登录的回调
-(void)didAutoLoginWithInfo:(NSDictionary *)loginInfo error:(EMError *)error{
    if (!error) {
        NSLog(@"%s 自动登录成功 %@",__FUNCTION__, loginInfo);
    }else{
        NSLog(@"自动登录失败 %@",error);
    }
    
}

// APP进入后台
- (void)applicationDidEnterBackground:(UIApplication *)application
{
    [[EMClient sharedClient] applicationDidEnterBackground:application];
}

// APP将要从后台返回
- (void)applicationWillEnterForeground:(UIApplication *)application
{
    [[EMClient sharedClient] applicationWillEnterForeground:application];
}

3.2 注册账号

 EMError *error = [[EMClient sharedClient] registerWithUsername:@"zbccc" password:@"zbccc"];
    if (error==nil) {
        NSLog(@"注册成功");
    }
    
    if (error) {
        NSLog(@"%@",error.errorDescription);
    }

3.2 登录

  
    [[EMClient sharedClient] loginWithUsername:@"zbccc"
                                      password:@"zbccc"
                                    completion:^(NSString *aUsername, EMError *aError) {
                                        if (!aError) {
                                            NSLog(@"登录成功");
                                        } else {
                                            NSLog(@"登录失败");
                                        }
                                    }];


//自动登录
EMError *error = [[EMClient sharedClient] loginWithUsername:@"8001" password:@"111111"];
if (!error)
{
   [[EMClient sharedClient].options setIsAutoLogin:YES];
}

3.3加好友

  [[EMClient sharedClient].contactManager addContact:@"8001"
                                           message:@"我想加您为好友"
                                        completion:^(NSString *aUsername, EMError *aError) {
                                            if (!aError) {
                                                NSLog(@"邀请发送成功");
                                            }
                                        }];

//同意好友申请
[[EMClient sharedClient].contactManager approveFriendRequestFromUser:@"8001"
                                                          completion:^(NSString *aUsername, EMError *aError) {
                                                              if (!aError) {
                                                                  NSLog(@"同意好友成功");
                                                              }
                                                          }];

//拒绝好友申请
[[EMClient sharedClient].contactManager declineFriendRequestFromUser:@"8001"
                                                          completion:^(NSString *aUsername, EMError *aError) {
                                                              if (!aError) {
                                                                  NSLog(@"拒绝好友成功");
                                                              }
                                                          }];

3.4获取好友

//从服务器获取所有的好友
[[EMClient sharedClient].contactManager getContactsFromServerWithCompletion:^(NSArray *aList, EMError *aError) {
    if (!aError) {
        NSLog(@"获取成功");
    }
}];
//从数据库获取所有的好友
NSArray *userlist = [[EMClient sharedClient].contactManager getContacts];

3.5删除好友

// 删除好友
[[EMClient sharedClient].contactManager deleteContact:@"8001"
                                           isDeleteConversation: YES
                                           completion:^(NSString *aUsername, EMError *aError) {
                                               if (!aError) {
                                                   NSLog(@"删除成功");
                                               }
