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

all I finally used transform and layer.cornerRadius too. But I have added translation to it to be center.

    private func setSwitchSize() {
    let iosSwitchSize = switchBlockAction.bounds.size
    let requiredSwitchSize = ...
    let transform = CGAffineTransform(a: requiredSwitchSize.width / iosSwitchSize.width, b: 0,
                                      c: 0, d:  requiredSwitchSize.height / iosSwitchSize.height,
                                      tx: (requiredSwitchSize.width - iosSwitchSize.width) / 2.0,
                                      ty: (requiredSwitchSize.height - iosSwitchSize.height) / 2.0)

    switchBlockAction.layer.cornerRadius = iosSwitchSize.height / 2.0
    switchBlockAction.transform = transform
}

And I did use backgroundColor and tintColor in designer. Hope it helps.
