PeerObjectiveC is WebRTC client library for iOS, that communicate to peerjs-server.

This library is modified from the AppRTCDemo (that Google has been published) for peerjs-server signaling process and PeerJS like API interface.

1. Clone this repository.

   $ git clone https://github.com/hiroeorz/PeerObjectiveC.git
   

2. And build it on Xcode.

1. Clone this repository.

   $ git clone https://github.com/hiroeorz/PeerObjectiveC.git
   

2. Copy Peer directory to your project, and add to your app on Xcode.

   $ cp -r PeerObjectiveC/Peer /path/to/yourapp/
   

3. You will need to add a few frameworks to your project in order for it to build correctly.

   • libc++.dylib
   • libicucore.dylib
   • Security.framework
   • CFNetwork.framework
   • GLKit.framework
   • libstdc++.6.dylib
   • AudioToolbox.framework
   • AVFoundation.framework
   • CoreAudio.framework
   • CoreMedia.framework
   • CoreVideo.framework
   • CoreGraphics.framework
   • OpenGLES.framework
   • QuartzCore.framework
   • libsqlite3.dylib

4. Initialize RTCPeerConnectionFactory in your AppDelegate.m

   AppDelegate.m

   #import "RTCPeerConnectionFactory.h"
   
   - (BOOL)application:(UIApplication *)application 
     didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
   {
       [RTCPeerConnectionFactory initializeSSL];
       return YES;
   }

5. And create instance of Peer class in ViewController.

   ViewController.m

   #import <AVFoundation/AVFoundation.h>
   #import "Peer.h"
   
   @interface ViewController () <RTCEAGLVideoViewDelegate>
   @property(nonatomic, strong) Peer *peer;
   @end
   
   @implementation ViewController {
   
   @synthesize peer = _peer;
   
   - (void)viewDidAppear:(BOOL)animate
   {
     __block typeof(self) __self = self;
   
     // Create Configuration object.
     NSDictionary *config = @{@"key": @"your_api_key", @"port": @(9000)};
   
     // Create Instance of Peer. 
     _peer = [[Peer alloc] initWithConfig:config];
   
     // Set Callbacks.
     _peer.onOpen = ^(NSString *id) {
       NSLog(@"onOpen");
     };
   
     _peer.onCall = ^(RTCSessionDescription *sdp) {
       NSLog(@"onCall");
     };
   
     _peer.onReceiveLocalVideoTrack = ^(RTCVideoTrack *videoTrack) {
       NSLog(@"onReceiveLocalVideoTrack");
     };
   
     _peer.onReceiveRemoteVideoTrack = ^(RTCVideoTrack *videoTrack) {
       NSLog(@"onReceiveRemoteVideoTrack");
     };
   
     _peer.onError = ^(NSError *error) {
       NSLog(@"onError: %@", error);
     };
   
     _peer.onClose = ^() {
       NSLog(@"onClose");
     };
   
     // Start signaling to peerjs-server.
     [_peer start:^(NSError *error){
       if (error) {
         NSLog(@"Error while openning websocket: %@", error);
       }
     }];
   }

   All default configuration is here.

   NSDictionary *config = @{@"host": @"0.peerjs.com",
                            @"port": @(80),
                            @"key": @"peerjs",
                            @"path": @"/",
                            @"secure": @(NO),
                            @"config": @{
                                @"iceServers": @[
                                    @{@"url": @"stun:stun.l.google.com:19302", @"user": @"", @"password": @""}
                                ]
                            }};
