Mac 下AppRTCDemo xcode 工程搭建和webrtc源码下载

提示（若不想自己下载源码或是编译，可到我的网盘提取： https://yunpan.cn/cYCbp5zIAAUqq  访问密码 ff5a

一、

（1） git clone https://github.com/pristineio/webrtc-build-scripts.git

（2）打开xcode工程，切换到WebRTC Dance，运行，则开始下载并编译代码（必须可以翻墙）

（3）切换到AppRTCDemo，运行

参考网址：

http://tech.pristine.io/build-ios-apprtc/

二、运行AppRTCDemo，可能会 遇到以下错误：

1.

解决：如下图，添加VideoToolbox.framework

2.  如下图错误：

.

解决：

到下面目录添加：ARDUtilities.h/m文件

3. demo起来后，iphone手机端没有视频

iphone手机端没有视频，是因为手机不能翻墙，

/src/talk/examples/objc/AppRTCDemo目录下替换ARDAppEngineClient.m和ARDCEODTURNClient.m两个文件 ，主要是将https://apprtc.appspot.com/  替换成 http://apprtc.diveinedu.com:8080（无需翻墙）
