How to assign a custom class programmatically in swift for UIButton

Question

I have created a UIButton with system type

let systemButton = UIButton(type: .system)

I have a subclass of UIButton named SSRadioButton.

Instead of doing this thing in IB, I want to do it programmatically. All suggestions are welcome.

No. My view controller will have nothing. Everything I need to do programmatically — Ramcharan Reddy, Jan 23 '17 at 12:45

Instead of

let systemButton = UIButton(type: .system)

Use,

let systemButton = SSRadioButton()

and do further activity.

If your intention is to make it programmatically, simply implement:

// make sure to setup the frame as it should...
let myButton = SSRadioButton(frame: CGRect(x: 0, y: 0, width: 500, height: 50))

// OR, for your case:
//let myButton = SSRadioButton(type: .system)

myButton.addTarget(self, action: #selector(myButtonPressed), for: .touchUpInside)
// setup all pther needed properties...

view.addSubview(myButton)

Target of the button:

func myButtonPressed() {
    print(#function)
}
