Floating button

some time we need to fix the button on uiview so that it will not change their position and clicking on it , we can extra event also.

1: for that we need to take the help of third party library.

Download the class of : KCFloatingActionButton

2: Now its time to load into UIViewController

3: take a parent UIWindow

4: Now add to UIViewController class :

func layout(){
         currentWindow = UIApplication.shared.keyWindow
        let fab = KCFloatingActionButton(frame: CGRect(x: CGFloat(SCREEN_WIDTH - 80), y: CGFloat(SCREEN_HEIGHT - 180), width: CGFloat(50), height: CGFloat(50)))
        fab.buttonColor = UIColor().HexToColor(hexString: accentColor)
        fab.plusColor = UIColor.white;
        fab.addItem(self.globalObjectCatalogProduct.languageBundle.localizedString(forKey: "sharetoother", value: "", table: nil), icon: UIImage(named: "icShare")){ item in
            self.sharetoOther();
        }
        fab.addItem(self.globalObjectCatalogProduct.languageBundle.localizedString(forKey: "addyourreview", value: "", table: nil), icon: UIImage(named: "ic_add_review")){ item in
          self.performSegue(withIdentifier: "addReviewSegue", sender: self)
        }
        fab.addItem(self.globalObjectCatalogProduct.languageBundle.localizedString(forKey: "addtowishlist", value: "", table: nil), icon: UIImage(named: "ic_wishlist_pdf")){ item in
            self.addToWishlist();
        }
        
        fab.fabDelegate = self
        fab.tag = 1300;
        currentWindow?.addSubview(fab)
    
        
    }

func layout(){

currentWindow = UIApplication.shared.keyWindow

let fab = KCFloatingActionButton(frame: CGRect(x: CGFloat(SCREEN_WIDTH - 80), y: CGFloat(SCREEN_HEIGHT - 180), width: CGFloat(50), height: CGFloat(50)))

fab.buttonColor = UIColor().HexToColor(hexString: accentColor)

fab.plusColor = UIColor.white;

fab.addItem(self.globalObjectCatalogProduct.languageBundle.localizedString(forKey: "sharetoother", value: "", table: nil), icon: UIImage(named: "icShare")){ item in

self.sharetoOther();

}

fab.addItem(self.globalObjectCatalogProduct.languageBundle.localizedString(forKey: "addyourreview", value: "", table: nil), icon: UIImage(named: "ic_add_review")){ item in

self.performSegue(withIdentifier: "addReviewSegue", sender: self)

}

fab.addItem(self.globalObjectCatalogProduct.languageBundle.localizedString(forKey: "addtowishlist", value: "", table: nil), icon: UIImage(named: "ic_wishlist_pdf")){ item in

self.addToWishlist();

}

fab.fabDelegate = self

fab.tag = 1300;

currentWindow?.addSubview(fab)

}

5: For removing we have to use:

 override func viewWillDisappear(_ animated: Bool) {
        currentWindow.viewWithTag(1300)?.removeFromSuperview();
        currentWindow = nil
    }

override func viewWillDisappear(_ animated: Bool) {

currentWindow.viewWithTag(1300)?.removeFromSuperview();

currentWindow = nil

}
