问题
What would be the class responsible for call answering screen. I think it's a private framework, or even the SpringBoard. But the SpringBoard has dozens of classes, and as I have access only to the header, it is difficult to know what the caller display phone service.
Does anyone know what class and method to the caller?
回答1:
There are two classes responsible for that (one for Phone call and second for facetime) in /System/Library/SpringBoardPlugins/IncomingCall.servicebundle/IncomingCall plugin
MPIncomingFaceTimeCallController
MPIncomingPhoneCallController
and -(id)newBottomBar selector.
The another way is writing a plugin for iEnhancer which deals with it, I can provide you plugin SDK.
