I´m developing a theos tweak and I would like to modify mainly the incoming call view (iOS 5 and iOS 6). I would appreciate the name of the class that handle this view for hook into it´s methods. I already try MPIncomingPhoneCallController and SBCallAlertDisplay and none of those had worked for me.
If you dump the headers on the InCallService.app (phone app), you will see a PHAlert class with a method called - (void)showOnViewController:(id)arg1;. This will display the "incoming call" view on top of any UIViewController. You can use this with the frontmost application: [[SpringBoard sharedApplication] _accessibilityFrontMostApplication].
