[kofsiwon]

Hey. What's wrong?

`
func setupFloatingMenu(){
self.floatingMenu.fabMenuItemSize = CGSize.init(width: 45, height: 45);
self.floatingMenu.shapePreset = .circle;
self.floatingMenu.delegate = self;

    var menuButton = FABButton(image: Icon.add, tintColor: .white);
    menuButton.backgroundColor = #colorLiteral(red: 0.1886929572, green: 0.4163666964, blue: 0.951190412, alpha: 1)
    menuButton.pulseColor = .white;
    self.floatingMenu.fabButton = menuButton;
    
    var reviewItem = FABMenuItem();
    reviewItem.title = "수강후기";
    reviewItem.titleLabel.fontSize = 13;
    reviewItem.titleLabel.textColor = .white;
    reviewItem.titleLabel.backgroundColor = .clear;
    reviewItem.fabButton.shadowColor = .black;
    reviewItem.fabButton.image = #imageLiteral(resourceName: "iconFreeReview");
    reviewItem.fabButton.backgroundColor = .white;
    reviewItem.fabButton.pulseColor = #colorLiteral(red: 0.1886929572, green: 0.4163666964, blue: 0.951190412, alpha: 1);
    
    var buyItem = FABMenuItem();
    buyItem.title = "수강신청";
    buyItem.titleLabel.fontSize = 13;
    buyItem.titleLabel.textColor = .white;
    buyItem.titleLabel.backgroundColor = .clear;
    buyItem.fabButton.shadowColor = .black;
    buyItem.fabButton.image = #imageLiteral(resourceName: "iconFreeBuy");
    buyItem.fabButton.backgroundColor = .white;
    buyItem.fabButton.pulseColor = #colorLiteral(red: 0.1886929572, green: 0.4163666964, blue: 0.951190412, alpha: 1);
    
    self.floatingMenu.fabMenuItems = [reviewItem, buyItem];
}

extension SWFreeLectureTableViewController : FABMenuDelegate{
func fabMenuWillOpen(fabMenu: FABMenu) {
self.blurView.isHidden = false;
self.blurView.alpha = 0;
UIView.animate(withDuration: 0.3, delay: 0) { [weak self] in
self?.blurView.alpha = 0.5;
fabMenu.fabButton?.imageView?.transform = .init(rotationAngle: 45);
} completion: { weak self in
//self?.blurView.isHidden = false;
}

    //    fabMenu.fabButton?.animate(.rotate(45))
    fabMenu.fabButton?.animate(.rotate(25));
}

func fabMenuWillClose(fabMenu: FABMenu) {
    self.blurView.alpha = 0.5;
    UIView.animate(withDuration: 0.3, delay: 0) { [weak self] in
        self?.blurView.alpha = 0;
        fabMenu.fabButton?.imageView?.transform = CGAffineTransform.identity;
    } completion: { [weak self](_) in
        self?.blurView.isHidden = true;
    }
    
    fabMenu.fabButton?.animate(.rotate(0));
}
