How to set button label in swift 3? [duplicate]

Question

@IBOutlet weak var catParentIdButton: UIButton!

I have this code and now I want to write the button label programmatically.
What will be the syntax to write the label of the button in swift 3.0?

Answer 1

Method Signature changed in Swift 3.0

func setTitle(_ title: String?, 
      for state: UIControlState) // Use this method to set the title for the button

example:

btn.setTitle(title: "Title", for: .normal)

Note default state of a btn control is changed to .Normal to .normal.

// previous 
public static var Normal: UIControlState { get }

// Swift 3.0
static var normal: UIControlState { get }
