i used rectangles test out program need make them buttons. how programmatically? 

import uikit

class interestviewcontroller: uiviewcontroller {

var squareview: uiview! var square: uiview! var frogs: uiview! var colson: uiview! var wwdc: uiview! var gravity: uigravitybehavior! var animator: uidynamicanimator! var collision: uicollisionbehavior! override func viewdidload() {     super.viewdidload()     squareview = uiview(frame: cgrectmake(100, 100, 100, 100))          view.addsubview(squareview)     animator = uidynamicanimator(referenceview: view)        squareview.backgroundcolor = uicolor.blackcolor()     gravity = uigravitybehavior(items: [squareview])     animator.addbehavior(gravity)     collision = uicollisionbehavior(items: [squareview])     collision.translatesreferenceboundsintoboundary = true     animator.addbehavior(collision)       // additional setup after loading view. }  override func didreceivememorywarning() {     super.didreceivememorywarning()     // dispose of resources can recreated. }

}

question: how programmatically?

short answer: don't. create buttons in ib. it's easier code first time, , way, waaaaay easier update , maintain. learn use ib. it's huge timesaver.

if bound , determined things hard way, you'll need use 1 of uibutton class initializers, buttonwithtype. you'd set frame , other attributes you're doing squareview.
