Toggle between select/deselect UIButton - ios

Question

I have a button which I want to change background color and text when tapped(select) and bring it back to its original state when tapped again (deselect). I am able to select it but I am not being able to deselect it. I have researched on SO and I am getting errors in this code in the if-else part
#IBAction func btn1Pressed(_ sender: AnyObject) {
sender.setTitleColor(UIColor.blue, for: UIControlState.normal)
(sender as! UIButton).backgroundColor = UIColor.green
if sender.isSelected {
sender.selected = false
}
else {
sender.selected = true
}
}

Answer 1

Try this:
#IBAction func btnPressed(_ sender: AnyObject) {
guard let button = sender as? UIButton else { return }
if !button.isSelected {
button.isSelected = true
button.setTitleColor(UIColor.blue, for: UIControl.State.normal)
button.backgroundColor = UIColor.green
}
else {
button.isSelected = false
button.setTitleColor(UIColor.green, for: UIControl.State.normal)
button.backgroundColor = UIColor.blue
}
}

It sounds to me like UISwitch is what you're looking for. Give it a try instead of wasting time implementing something that's already there for you.

Answer 3

try this
#IBAction func btn1Pressed(sender: UIButton) {
if sender.selected {
sender.selected = false
sender.setTitleColor(UIColor.redColor(), forState: .Normal)
sender.backgroundColor = UIColor.blackColor()
}
else {
sender.selected = true
sender.setTitleColor(UIColor.redColor(), forState: .Selected)
sender.backgroundColor = UIColor.blackColor()
}
}

Answer 4

Change background color of selected button from storyboard like below in state config choose selected and then change background color and also coustomize default for normal button.
and use below in action
(sender as! UIButton).selected = !(sender as! UIButton).selected

Answer 5

Please try this code first you need to crate action and propert of the button like
#IBOutlet var btn_ButtonPressed: UIButton!
then Action.
#IBAction func click_ButtonPressed(_ sender: Any) {
if !sender.isSelected() {
sender.selected = true
btn_ButtonPressed.setTitleColor(UIColor.red, forState: .normal)
btn_ButtonPressed.backgroundColor = UIColor.yellow
}
else {
sender.selected = false
btn_ButtonPressed.setTitleColor(UIColor.yellow, forState: .normal)
btn_ButtonPressed.backgroundColor = UIColor.red
}
}

Answer 6

this one worked fine for me!
//
#IBAction func buttonColorChanger(sender : UIButton ) {
if button.isSelected == false
{
button.backgroundColor = UIColor.purple
print("selected")
button.setTitle("selected", for: .normal)
button.setTitleColor(UIColor.white, for: .normal)
button.isSelected = true
}else{
button.backgroundColor = UIColor.white
print("unselected")
button.isSelected = false
}
}

A cleaner approach would be:
#objc private func buttonTapped(_ sender: UIButton) {
sender.isSelected.toggle()
if selected {
// Setup appearance for selected state.
} else {
// Setup appearance for deselected state.
}
}
