Help/Support How to %hook RootViewController function

[KingRalph 816 9.3.5]

I'm trying to modify the properties of an instance variable, so I decided to hook the variable inside the init function (because init is called first). Can someone please review my code? I feel like I'm missing something.

%hook RootViewController
 
- (id)init {
// Hook the instance variable for the ad's view 
adsView = MSHookIvar<UIView *>(self, "_bannerViewContainer");
// Hide the ad's UIView
adsView.hidden = YES;
 
return %orig;
}
%end

I re-coded the tweak. Decided to hook the GADViewController class function instead hooking of the instance variable.

Here is the updated code:

#import <substrate.h>
#import <Foundation/Foundation.h>

%hook GADBannerView

- (void)setFrame:(CGRect)frame {
    frame = CGRectMake(0,0,0,0);
    %orig(frame);
}

%end
