Change color of UISwitch in “off” state

Question

I\'ve learned that we can change the UISwitch button appearance in its \"on\" state, but is it also possible to change the color of the UISwitch in the \"off\" state?

Answer 1

Should you need other switches around your app, it might be also a good idea implementing @LongPham's code inside a custom class. As others have pointed out, for the "off" state you'll need to change the background colour as well, since the default is transparent.

class MySwitch: UISwitch {

  required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)

    // Setting "on" state colour
    self.onTintColor        = UIColor.green

    // Setting "off" state colour
    self.tintColor          = UIColor.red
    self.layer.cornerRadius = self.frame.height / 2
    self.backgroundColor    = UIColor.red
  }
}
