webrtc 编译完成，安装时错误

历尽千辛万苦，webrtc编译完成。如果能能走到这一步，那么恭喜你，你已经打败99%的人了。最后就是安装到真机上面测试，还有最后一个问题需要解决。

执行安装命令

ideviceinstaller -i out_ios/Debug-iphoneos/AppRTCDemo.app

发生错误：

Install failed.
Failed to verify code signature

错误日志

ERROR: Install failed. Got error "ApplicationVerificationFailed" with code 0xe8008016: Failed to verify code signature of <MIExecutableBundle : path = /private/var/mobile/Library/Caches/com.apple.mobile.installd.staging/temp.Ufd0uM/extracted/AppRTCDemo.app identifier = com.google.AppRTCDemo type = 4> : 0xe8008016 (Entitlements found that are not permitted by provisioning profile)

这是由于bundleid和签名不一致引起的，如何修改过签名证书，一般回发生这个错误

webrtc 默认的bundleid 为

com.google.AppRTCDemo

存在这个文件里：

./examples/objc/AppRTCDemo/ios/Info.plist

将下面这两行里的com.google.AppRTCDemo改为合适的bundleid

<key>CFBundleIdentifier</key>
<string>com.google.AppRTCDemo</string>

重新执行脚本生成编译工程：

webrtc/build/gyp_webrtc

再执行编译 ：

ninja -C out_ios/Debug-iphoneos AppRTCDemo

成功编译后执行以下命令安装app：

 ideviceinstaller -i out_ios/Debug-iphoneos/AppRTCDemo.app

若能成功输出：

Uploading AppRTCDemo.app package contents... DONE.
Installing '(null)'
Install: CreatingStagingDirectory (5%)

到这里大功告成。
