        let borderLayer = CALayer()
        let widthOfBorder = getBorderWidht()
        borderLayer.frame = CGRectMake(-15, self.frame.size.height - widthOfBorder, self.frame.size.width+20, self.frame.size.height)
        borderLayer.borderWidth = widthOfBorder
        borderLayer.borderColor = getBottomLineColor()
        self.layer.addSublayer(borderLayer)
        self.layer.masksToBounds = true
        
    }

            let leftimageView = UIImageView.init(frame: CGRectMake(0, 0, 20, 20))//Create a imageView for left side.
            leftimageView.image = SideImage
            leftAddView.addSubview(leftimageView)
            self.leftView = leftAddView
            self.leftViewMode = UITextFieldViewMode.Always

    }
    
    
    func getBottomLineColor() -> CGColor {
        return bottomLineColor.CGColor;
        
    }
    @IBInspectable var cusborderWidth:CGFloat = 1.0
