How can i reset UIlabel attributes to default settings in swift - ios

Question

I created a UIlabel named etiket. then I created an action button and I made changes like color change on it. it's a sample:
#IBAction func changeColor(_ sender: Any) {
etiket.textColor = UIColor.red
then I created again an action button and now when I pressed the button I want to reset UIlabel to default settings.
I tried this method
#IBAction func sifirla(_ sender: Any) {
etiket.text = "nil"
when I tried this method UIlabel completely disappeared.
How can I reset UIlabel attributes to default settings?
I did some research, but I could not find exactly what I wanted.

You need to create a label dynamically and assign a tag value to it.
func createLabel() -> UILabel {
let lbl = UILabel(frame: CGRect(x: 10, y: 10, width: 100, height: 55))
lbl.tag = 101
//set other properties of label
return lbl
}
In changeColor method you need to get label by tag value and set its color.
#IBAction func changeColor(_ sender: Any) {
if let lbl = self.view.viewWithTag(101) as? UILabel {
lbl.textColor = UIColor.red
}
}
In sifirla method you need to get label by tag value and remove it from its super view and create a new label and add it in your current view, so by adding a new UILabel instance you will get default settings of label.
#IBAction func sifirla(_ sender: Any) {
if let lbl = self.view.viewWithTag(101) as? UILabel {
lbl.removeFromSuperview()
let newLbl = self.createLabel()
self.view.addSubview(newLbl)
}
}
Note: If you are using autolayout then you need to set constraint to label instead of frame.
