3.xと4.xの差分

  • func onClickMyButton(sender: UIButton) と func moviePlayBackDidFinish(notification: NSNotification) に @objc を追加

2.xと3.xの差分

  • UIColorによる色指定の簡略化
  • NSURLからURLに変更
  • CGRectMake(CGFloat, CGFloat, CGFloat, CGFloat)からCGRect(x: CGFloat, y: CGFloat, width: CGFloat, height: CGFloat)に変更
  • UIButton.setTitle(String?, forState: UIControlState)からUIButton.setTitle(String?, for: UIControlState)に変更
  • NSNotificationCenter.defaultCenter().addObserver(AnyObject, selector: Selector, name: String?, object: AnyObject?)からNotificationCenter.default.addObserver(AnyObject, selector: Selector, name: NSNotification.Name?, object: AnyObject?)に変更
  • NSNotificationCenter.defaultCenter().removeObserver(AnyObject, name: String?, object: AnyObject?)からNotificationCenter.default.removeObserver(AnyObject, name: NSNotification.Name?, object: AnyObject?)に変更
