How I can create Custom view element with animation like a separate class for all view controllers, so that not write this element each time for each VC.
For example:
I am want create bottom view with button and if I am press on button animation will be appeared, and I am can do different action for different VC.
How I can create this view with animation one time for all VC and implement different action inside VC?
I can only create it each time for each VC, all work done but it's terrible code and sometimes may be hard for maintenance.
This it example how I am create my bottom menu and this way looking good but how work.
import Foundation
import UIKit
class BottomMenu: UIViewController {
static let shared = BottomMenu()
var yPosBottomUIView: CGFloat = 90.0
var yPosCenterButton: CGFloat = 35
var yPosBackButton: CGFloat = 35
var yPosForwardButton: CGFloat = 35
var yPosContextMenu: CGFloat = 35
var yPosUpdateButton: CGFloat = 35
var backButtonEnable: Bool = false
var forwardButtonEnable: Bool = false
lazy var image: UIImageView = {
let image = UIImageView(frame: CGRect(x: 0, y: UIScreen.main.bounds.maxY - yPosBottomUIView, width: UIScreen.main.bounds.width, height: 90))
if (osTheme == .dark) {
DispatchQueue.main.async {
image.image = UIImage(named: "SurfaceBlack")
}
return image
} else {
DispatchQueue.main.async {
image.image = UIImage(named: "SurfaceLight")
}
return image
}
}()
lazy var centerButton: UIButton = {
let button = UIButton(frame: CGRect(x: (UIScreen.main.bounds.maxX / 2) - 25, y: (UIScreen.main.bounds.maxY - 50) - yPosCenterButton, width: 50, height: 50))
if (osTheme == .dark) {
button.backgroundColor = UIColor(red: 0.118, green: 0.118, blue: 0.15, alpha: 1)
} else {
button.backgroundColor = UIColor(red: 0.118, green: 0.118, blue: 0.15, alpha: 1)
}
button.layer.cornerRadius = 25
button.setImage(UIImage(named: "Menu"), for: .normal)
button.addTarget(self, action: #selector(centralButtonAction), for: .touchUpInside)
button.isEnabled = false
return button
}()
lazy var backButton: UIButton = {
let button = UIButton(frame: CGRect(x: (UIScreen.main.bounds.minX) + 25, y: (UIScreen.main.bounds.maxY - 15.5) - yPosBackButton, width: 36, height: 36))
button.backgroundColor = .clear
button.setImage(UIImage(named: "whiteBackArrow"), for: .normal)
button.addTarget(self, action: #selector(centralButtonAction), for: .touchUpInside)
button.isEnabled = backButtonEnable
return button
}()
lazy var forwardButton: UIButton = {
let button = UIButton(frame: CGRect(x: (UIScreen.main.bounds.minX) + 90, y: (UIScreen.main.bounds.maxY - 15.5) - yPosForwardButton, width: 36, height: 36))
button.backgroundColor = .clear
button.setImage(UIImage(named: "whiteBackArrow"), for: .normal)
button.imageView?.transform = CGAffineTransform(rotationAngle: CGFloat.pi)
button.addTarget(self, action: #selector(centralButtonAction), for: .touchUpInside)
button.isEnabled = forwardButtonEnable
return button
}()
lazy var contextMenu: UIButton = {
let button = UIButton(frame: CGRect(x: (UIScreen.main.bounds.maxX) - 60, y: (UIScreen.main.bounds.maxY - 15.5) - yPosContextMenu, width: 36, height: 36))
button.backgroundColor = .clear
button.setImage(UIImage(named: "ContextMenu"), for: .normal)
button.addTarget(self, action: #selector(contextMenuButtonAction), for: .touchUpInside)
return button
}()
lazy var updateButton: UIButton = {
let button = UIButton(frame: CGRect(x: (UIScreen.main.bounds.maxX) - 125, y: (UIScreen.main.bounds.maxY - 15.5) - yPosUpdateButton, width: 36, height: 36))
button.backgroundColor = .clear
button.setImage(UIImage(named: "updateN"), for: .normal)
button.addTarget(self, action: #selector(centralButtonAction), for: .touchUpInside)
button.isEnabled = false
return button
}()
lazy var blur: UIVisualEffectView = {
let blurEffectView = UIVisualEffectView(frame: CGRect(x: 0, y: 0, width: UIScreen.main.bounds.width, height: UIScreen.main.bounds.height))
let blurEffect = UIBlurEffect(style: .dark)
blurEffectView.effect = blurEffect
blurEffectView.alpha = 0
return blurEffectView
}()
#objc func centralButtonAction(_ sender: UIButton?) {
print("Center Tapped")
}
#objc func contextMenuButtonAction(_ sender: UIButton?) {
print("Context Menu Tapped")
// IF I am past blur effect here and some action for diffent VC nothing happens but each time I'll saw printed text above)
}
}
This is image of menu which I am create but I am write code each time for each VC
Menu have ... when I press on it I am show the same animation for all VC and add some others view BUT When I am closed others sub view I am want implement different action depend of VC where menu did be opened.

Did you tried making one controller as base controller that can be inherited by all child controller and the common actions/activites to be part of that controller. Or maybe using a container view for child controller so that you can inherit properties of your base controller to your child controller.It depends on whatever suits your actual requirements
