If statement not working with NSNumber?

Question

I'm new to coding and can't find an accurate answer anywhere. I'm trying to make the NSNumber return false if the BOOL is true. Any help? Thanks

static BOOL someBOOL;

%hook  (class I want to hook)

-(void)sampleMethod:(NSNumber *)boolNumber
{
    if (!someBOOL) 
    {
        [NSNumber numberWithBool:NO];
    } 
    else 
    {
        return %orig;
    }
}

%end

Sorry I forgot to state this is a tweak for jailbreak, so %hook is used to hook into a class and use its methods — Andrew68, May 11 '14 at 21:27
You're forgetting the `return`, also your method states `void` as a return value, not `NSNumber` — Marcel, May 11 '14 at 21:34

Init someBOOL:

static BOOL someBOOL = YES;

Then

if (!someBOOL) 
{
    return [NSNumber numberWithBool:NO];
} 
else 
{
    return %orig;
}

And to return replace void with NSNumber and remove excess parameter

-(NSNumber*)sampleMethod

To get returned value:

NSNumber *n = [self sampleMethod];

I did this and I got the error: "cannot initialize return object of type 'BOOL' (aka 'signed char') with an rvalue of type NSNumber *" – Andrew68 May 11 '14 at 21:47
Where does NSNumber *n = [self sampleMethod]; go? – Andrew68 May 11 '14 at 22:09
NSNumber has a method called boolValue. Use it on the line that is causing this: "cannot initialize return object of type 'BOOL' (aka 'signed char') with an rvalue of type NSNumber *'.

@nicael Please use either `YES` or `NO` to initialize a `BOOL` variable. Also keep in mind that `someBool` will be initialized to `NO` by default. – rmaddy May 12 '14 at 00:18
