Whats the code for button action?

Question

Me again, I'm loving this library but running into minor issues here and there.

For RaisedButton, what code is needed to create an action when the button is create programatically?

btn1.addTarget(self, action: "okButton", forControlEvents: UIControlEvents.TouchUpInside)

func okButton(sender:RaisedButton!) {
    print("button pressed")
}

results in unrecognized selector sent to instance.

Is `okButton(_:)` in the same view controller as where you add the target? And if `okButton(_:)` expects a parameter, you'll have to add the colon. — Eendje, Feb 13 '16 at 03:09

You will need to give "okButton:" as action as it takes an argument.

Try:

btn1.addTarget(self, action: "okButton:", forControlEvents: UIControlEvents.TouchUpInside)

In your code remove the unwrapping of the optional parameter:

func okButton(sender: RaisedButton) {
    print("button pressed")
}

Add the ":" at the end of your selector name:

btn1.addTarget(self, action: "okButton:", forControlEvents: .TouchUpInside)

That should solve your issue :)
