1、建议使用cocoapods导入环信SDK



pod 'HyphenateSDK', :git => 'https://github.com/easemob/hyphenate-cocoapods.git'

2、导入EaseUI，将EaseUI拖入工程中

https://github.com/easemob/easeui_ios/tree/new_dev

最坑的报错如下

错误截图

修改错误

原因是因为里面有.c文件，一般情况下出现“Unknown type name”是头文件互相引用出现的，这里可以排除，由于源码使用是c\c++与oc混编，

考虑新的XCode编译文件类型导致的，尝试了几种方案，下面三种可以解决问题。解决方案：.c文件，将属性的 identity and type 改为Objective-C Source。

3、初始化SDK、注册、登录


#pragma mark - setupEMSDK
- (void)setupEMSDK
{
    //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:EMSDKAppKey];
    options.enableConsoleLog = NO;
    options.apnsCertName = EMSDKApnsCertName;
    [[EMClient sharedClient] initializeSDKWithOptions:options];
    [[EMClient sharedClient] addDelegate:self delegateQueue:nil];

    EMError *error1 = [[EMClient sharedClient] registerWithUsername:@"test" password:@"123456"];
    if (error1==nil) {
        NSLog(@"注册成功");
    }else {
        MMHLog(@"注册失败");
    }
    
    EMError *error = [[EMClient sharedClient] loginWithUsername:@"test" password:@"123456"];
    if (!error) {
        MMHLog(@"登录成功");
    } else {
        MMHLog(@"登录失败");
    }
}

- (void)applicationWillResignActive:(UIApplication *)application {

}

//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];
}

或者后台新建用户
如果有用户登录则变成绿色状态

新建用户

4、自动登录



    EMError *error = [[EMClient sharedClient] loginWithUsername:@"test" password:@"123456"];
    if (!error){
        [[EMClient sharedClient].options setIsAutoLogin:YES];
    }
