How to hide control center status bar in Theos tweak?

Question

I'm starting my adventure with creating tweaks for a jailbroken iPhone. I installed the FLEXing tweak from the NSCake repo and while browsing through the headers I encountered a problem. I want to hide control center status bar, but the code doesn't work. I've tried using -(void)setHidden and -(void)isHidden.

Tweak.x:

%hook CCUIStatusBar
    -(void)setHidden:(bool)hidden {
        %orig(YES);
    }
%end
