之前在弄环信的视频通话，找了好久都没有找到资源，尤其是简书上面，虽然环信官方有集成音视频的视频，但是那个是在太模糊了，我这里只能被动接收视频，下面开始吧
我用的SDK是这个ios_IM_sdk_V3.1.4
1.将HyphenateFullSDK导入项目中然后
class.png
这些环信官方文档都有滴
2.登录注册的接口加入项目中
重点来了
3
ChatDemoHelper.h 我进行了删减

这里需要注意一点，ViewController.h 是根据你的主视图控制器来进行更改，环信上面是UITabBarController，随你喜欢了。。。
ViewController.m
//
// ViewController.m
// Two
//
// Created by maxh on 16/8/4.
// Copyright © 2016年 merise. All rights reserved.
//
#import "ViewController.h"
#import "ChatDemoHelper.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
[ChatDemoHelper shareHelper].mainVC = self;
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
@end
这里是给主视图控制器赋值
最后不要忘了创建PCH文件把#import "EMSDKFull.h"
define DEMO_CALL 1 这两个放进去哈，，啦啦啦，完成了，可以接听视频了
更新：
环信3.2.0之后新增加了DemoCallManager这个类，然而并不用担心，你直接把环信demo里面的call那个文件里面的类导入工程，其他的不用动，就和原来的一样的
