Build CEF in mac without implementing CefAppProtocol

[rahulchavan10]

Want to build CEF in mac without forcing the user of my library to implement CefAppProtocol. It will be very painful for them.

Please suggest some way where I can build CEF witout implementing CefAppProtocol.

I tried, but it is throwing below exception.

This is not supported.

Yes, It is not possible without implementing CefAppProtocol to avoid crashes at runtime.
I think it is possible to extend it in your 'library' through 'Extension and Category' in Objective C.
