Notification throws exception

It did work as it should in my previous project but all of a sudden it throws exception and I've compared two, can't really figure out because both situations are identical.

This is what I'm getting -

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UISwipeGestureRecognizer toggleMenu:]: unrecognized selector sent to instance 0x7fb663f3cda0'

In OptionView.m

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(toggleMenu:) name:@"toggleMenuYes" object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(toggleMenu:) name:@"toggleMenuNo" object:nil];

-(void)toggleMenu:(NSNotification *)shouldOpenMenu{
[self.animator removeAllBehaviors];

NSString *one = @"1";

if (shouldOpenMenu.object == one) {
    NSLog(@"yes");
    self.yesOrNo = YES;  
}
else {
    self.yesOrNo = NO;  
}   

}

In myVC.m

UISwipeGestureRecognizer *showMenuGesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self
                                                                                          action:@selector(handleGesture:)];
    showMenuGesture.direction = UISwipeGestureRecognizerDirectionRight;
    [self.optionViewCell addGestureRecognizer:showMenuGesture];
    showMenuGesture.delegate = self;


    UISwipeGestureRecognizer *hideMenuGesture = [[UISwipeGestureRecognizer alloc] initWithTarget:self
                                                                                          action:@selector(handleGesture:)];
    hideMenuGesture.direction = UISwipeGestureRecognizerDirectionLeft;
    [self.optionViewCell addGestureRecognizer:hideMenuGesture];
    hideMenuGesture.delegate = self;


-(void)handleGesture:(UISwipeGestureRecognizer *)gesture{

if (gesture.direction == UISwipeGestureRecognizerDirectionRight) {

    [[NSNotificationCenter defaultCenter] postNotificationName:@"toggleMenuYes" object:@"1"];
}
else{

    [[NSNotificationCenter defaultCenter] postNotificationName:@"toggleMenuNo" object:@"0"];
}

}
