What's wrong with my code? (obj c tweak development)

Question

So, I'm new to tweak development and obj c and I'm trying to change the style of dock with this code

%hook SBWallpaperEffect
-(void)setStyle: (NSInteger)arg1{
    arg1 = 5;
}
%end

But it doesn't work. What am I doing wrong?

Answer 1

Ok so i figured out that im using NSInteger instead of long long. Like this:

• (void)setStyle:(long long)arg1;

Also, i was using

SBWallpaperEffect

Instead of

SBWallpaperEffectView

And i should've set the value inside %orig

So, this is the right way to write it:

%hook SBWallpaperEffectView
- (void)setStyle:(long long)arg1{
    arg1 = 5;
    %orig(arg1);
    return;
}
%end
