ios - Swift subclass UIView

Question

I want to subclass UIView and show a login like view. I've created this in Objective-C, but now I want to port it to Swift. I do not use storyboards, so I create all my UI in code.

But the first problem is that I must implement initWithCoder. I gave it a default implementation since It won't be called. Now when I run the program it crashes, because I've to implement initWithFrame as well. Now I got this:

override init() {
    super.init()
    println("Default init")
}

override init(frame: CGRect) {
    super.init(frame: frame)
    println("Frame init")
}

required init(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    println("Coder init")
}

My question is where should I create my textfield etc... and if I never implement frame and coder how can I "hide" this?

Answer 1

I usually do something like this, its a bit verbose.

class MyView: UIView {
    override init(frame: CGRect) {
        super.init(frame: frame)
        addBehavior()
    }

    convenience init() {
        self.init(frame: CGRect.zero)
    }

    required init(coder aDecoder: NSCoder) {
        fatalError("This class does not support NSCoding")
    }

    func addBehavior() {
        print("Add all the behavior here")
    }
}



let u = MyView(frame: CGRect.zero)
let v = MyView()

(Edit: I've edited my answer so that the relation between the initializers is more clear)
