I’m trying to subclass UITextField, but I get this error:

Unable to call non-designated initializer as super constructor

. The code I have is:

private class Select: UITextField {

    @OverrideInit
    constructor(): super()

    override fun caretRectForPosition(position: UITextPosition): CValue<CGRect> {
        return CGRectMake(x = 0.0, y = 0.0, width = 0.0, height = 0.0)
    }

    override fun selectionRectsForRange(range: UITextRange): List<*> {
        return listOf<Any?>(null)
    }

    override fun canPerformAction(action: COpaquePointer?, withSender: Any?): Boolean {
        return false
    }
}

Anyone know what should I do? I guess I could use

disableDesignatedInitializerChecks

but that doesn’t seem right

not sure how to spell this in Kotlin but you should be calling

super(frame: CGRectZero)

, I believe

Thanks! I added:

UITextField(frame = CGRectZero.readValue())

Let’s see if it works 🙂

UITextField(cValue())

should work

And what about the override of selectionRectsForRange? The way I was overriding it, it gives me an error about the null
