3.xと4.xの差分

• UITextBorderStyle が UITextField.BorderStyle に変更
• UIMenuControllerArrowDirection が UIMenuController.ArrowDirection に変更
• internal func onMenu の 1~3 に @objc を追加

2.3と3.0の差分

• UIColorの参照方法が変更(UIColor.grayColor()->UIColor.gray)
• CGRect,CGPointの初期化方法の変更(CGRectMake,CGPointMakeの廃止)
• UIMenuControllerのプロパティ名、メソッド名が一部変更(sharedMenuController()->shared)
• UITextFieldDelegateのデリゲートメソッドの引数が変化
• CGRectZeroがCGRect.zeroに変更
