isbx_apprtc_在ios的使用

ISBX apprtc 在iOS的使用

1. 把WebRTC视频聊天集成到你的app中

项目目录 - 终端中输入 pod install AppRTC

2. 从这里你可以找到ARTCVideoChatViewController类 ,接下来集成的详细步骤:

1. 初始化SSL peer 连接

WebRTC可以通过SSL安全通信. 如果你要测试https,这是必须的. 你要修改你的appDelegate.m如下:

1. #import "RTCPeerConnectionFactory.h"
2. 在 didFinishLaunchingWithOption:方法中加入 : [RTCPeerConnectionFactory initializeSSL];
3. 在applicationWillTerminate: 方法中: [RTCPeerConnectionFactory deinitializeSSL];

2. 添加视频聊天

需要两个控件:

• Local Video View : 显示设备相机
• Remote Video View : 显示远程相机.

步骤:

• 1.在你的ViewController或无论什么要放这两个视图的类中 ,引入:

#import <libjingle_peerconnection/RTCEAGLVideoView.h>
#import <AppRTC/ARDAppClient.h>

• 2.这个类要实现ARDAppClientDelegate 和 RTCEAGLVideoViewDelegate 协议.

@interface ARTCVideoChatViewController : UIViewController <ARDAppClientDelegate, RTCEAGLVideoViewDelegate>

//ARDAppClientDelegate: 管理当远程客户端连接和断开实践. 同时处理收到本地和远程视频提要.
//RTCEAGLVideoViewDelegate : 负责确定视频帧大小.

• 3.定义这些属性:

//执行AppRTC服务器连接并加入聊天室
@property (strong, nonatomic) ARDAppClient *client;
//视图中显示的远程视频
@property (strong, nonatomic) IBOutlet RTCEAGLVideoView *remoteView;
//显示的本地视频
@property (strong, nonatomic) IBOutlet RTCEAGLVideoView *localView;
@property (strong, nonatomic) RTCVideoTrack *localVideoTrack;
@property (strong, nonatomic) RTCVideoTrack *remoteVideoTrack;

• 4.初始化这些属性,并设置代理

/* Initializes the ARDAppClient with the delegate assignment */
  self.client = [[ARDAppClient alloc] initWithDelegate:self];

  /* RTCEAGLVideoViewDelegate provides notifications on video frame dimensions */
  [self.remoteView setDelegate:self];
  [self.localView setDelegate:self];

• 5.接入一个视频聊天室

// 设置Url
[self.client setServerHostUrl:@"https://apprtc.appspot.com"];
[self.client connectToRoomWithId:@"room123" options:nil];

主要内容在connectRoomWithId: option:里面:

1. 首先把state 更改为kARDAppClientStateConnecting.
2. 发送TURN Request.

3. 注册room服务器

   • 1. 处理ARDAPPClientDelegate方法事件

//连接状态.
- (void)appClient:(ARDAppClient *)client didChangeState:(ARDAppClientState)state {
switch (state) {
    case kARDAppClientStateConnected:
        NSLog(@"Client connected.");
        break;
    case kARDAppClientStateConnecting:
        NSLog(@"Client connecting.");
        break;
    case kARDAppClientStateDisconnected:
        NSLog(@"Client disconnected.");
        [self remoteDisconnected];
        break;
}
}
//接收本地视频轨迹
- (void)appClient:(ARDAppClient *)client didReceiveLocalVideoTrack:(RTCVideoTrack *)localVideoTrack {
self.localVideoTrack = localVideoTrack;
[self.localVideoTrack addRenderer:self.localView];
}
//接收远程视频轨迹
- (void)appClient:(ARDAppClient *)client didReceiveRemoteVideoTrack:(RTCVideoTrack *)remoteVideoTrack {
self.remoteVideoTrack = remoteVideoTrack;
[self.remoteVideoTrack addRenderer:self.remoteView];
}

- (void)appClient:(ARDAppClient *)client didError:(NSError *)error {
/* Handle the error */
}

• 7.处理RTCEAGLVideoViewDelegate回调

- (void)videoView:(RTCEAGLVideoView *)videoView didChangeVideoSize:(CGSize)size { //根据返回的大小调整localView或remoteView }
