init UIView with arguments?

Question

My UIView looks like this :

  override init (frame : CGRect)
    {

        super.init(frame : frame)

    }

I would like to add an argument such as :

 override init (frame : CGRect, number:Int)

What is the right way to do it so I can init and send arg in one line ?

Answer 1

You would define your class something like this:

class MyView: UIView {
    let number: Int

    init(frame: CGRect, number: Int) {
        self.number = number

        super.init(frame: frame)
    }

    required init?(coder aDecoder: NSCoder) {
        // Need to initialize the number property here. Do so appropriately.
        super.init(coder: aDecoder)
    }
}

The use of the number property is just an example. Do what you actually need.

And you would create an instance like this:

let mv = MyView(frame: .zero, number: 42)

Obviously you would pass a useful frame.
