A bit too much story-telling here. > Source/WebKit2/UIProcess/ApplicationStateTracker.mm:76 > -ApplicationStateTracker::ApplicationStateTracker(UIView *view, SEL didEnterBackgroundSelector, SEL willEnterForegroundSelector) > +ApplicationStateTracker::ApplicationStateTracker(UIView *view, SEL didEnterBackgroundSelector, SEL didFinishSnapshottingAfterEnteringBackgroundSelector, SEL willEnterForegroundSelector) Why all this selector magic, rather than just an Obj-C protocol or something?
