Change all UIViewControllers Backgrounds












1















I want to change all my project's UIViewControllers, so I have this:



let bg = BackgroundImage().backgroundImage
bg.alpha = 0.2
bg.frame = self.view.frame

let wBg = UIView()
wBg.frame = self.view.frame
wBg.backgroundColor = UIColor(white: 1, alpha: 0.5)

self.view.addSubview(wBg)
self.view.sendSubview(toBack: wBg)

self.view.addSubview(bg)
self.view.sendSubview(toBack: bg)


Where BackgroundImage().backgroundImage returns a UIImageView.



But how can I implement this on all my UIViewControllers without having to copy/paste the same in all my VC.

          One solution is to create a function in a UIViewController extension. This function should setup the view controller's background as needed.



          Then in the viewDidLoad function of each of your view controllers you can call that extension function.

          1. Create BaseViewController.swift



          class BaseViewController: UIViewController {
          override func viewDidLoad() {
          setBackgroundImage()
          }

          setBackgroundImage() {

          }
          }


          2. Other ViewController will inherit the BaseViewController



          class TimelinesViewController: BaseViewController {

          }

            The problem with this solution is that it doesn't work for table view controllers and collection view controllers and others.
