How to use a storyboard example

[JhonnyTawk]

How can I implement this behavior in storyboard?

[hungMta]

Let's implement this:
public required init?(coder aDecoder: NSCoder) { super.init(coder: aDecoder) Width = frame.width Height = frame.height }

The init of WormTabStrip doesn't setup Width and Height of TabStrip.
