简单集成环信视频通话
集成环信语音通话和视频通话
环信
iOS 环信集成
iOS 环信3.2.3 集成聊天，语音，视频，通话
IOS环信集成单聊
 集成环信IM(单聊)
ios环信3.0版本集成(包含音频通话)
iOS 环信集成视频
环信

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

0d97265428a6:作者您好。我现在毕设在这方面陷入了困境。请您帮帮忙。万分感谢。
403cd85e800d:我只想集成一个接收视频被呼叫的功能,能加个qq详细聊一下么,我的:30329533
403cd85e800d:@风飞燕其实我最没看懂的是怎么唤起接收视频聊天这个功能,都需要哪些文件?
403cd85e800d:@风飞燕恩,我用pod集成的环信,然后我还需要把什么文件导入工程?Call的那个文件夹,还有其他什么东西么?
前端杜若:@如来撸管子如果你只想做接收视频的功能，你就把己方呼出功能注释掉就行
爱吃米饭的陈大鹰:请问一下环信的视频支持一种功能嘛?就是那种类似视频连麦一样,主播可以控制,在和A聊天的时候其他人不能聊天,然后A走之后下一个用户才能聊天?
前端杜若:@爱吃米饭的陈大鹰这个你要去问问环信技术，我没有弄过这个
c471f18d2f00:你那的视频通话画面清晰吗?我这码率调到最大5000了,画面还是很模糊
南巷旧人M:大神您好，我现在的需求就是吧整个的环信的示例demo移植到我的app中，但是老报错，大神能不能给一个demo？
南巷旧人M:@风飞燕你有视频链接吗？
南巷旧人M:@风飞燕视频好像是老版本的
前端杜若:@南巷旧人M 这个你可以看着环信的视频做，很清楚的
Mr_某某某:你好,我想请教一些关于环信视频的问题.方便给个扣扣号吗?
Hero_Guo:我只想实现双方简单的视屏通话, 该删哪些呢? 愁人...
前端杜若:@Hero_Guo 你先能看到视频了在修改界面嘛，ChatDemoHelper这个类很重要
前端杜若:@Hero_Guo 你需要CallViewController、ChatDemoHelper这两个类 ChatDemoHelper里面删掉不是#if DEMO_CALL == 1 ~#endif这里面的东西，CallViewController 你先删掉不需要的头文件保留#import <CoreTelephony/CTCallCenter.h>
#import <CoreTelephony/CTCall.h>
#import "CallViewController.h"

#import "ChatDemoHelper.h"
保留这些，然后看着删吧
前端杜若:我帮你看看，等会
Hero_Guo:需要在自己的工程中导入环信的 CellViewController 吗?
前端杜若:@Hero_Guo 如果你要自己写界面也可以
前端杜若:@Hero_Guo 需要，但是你要把不需要的代码删掉
