        super.init(coder: aDecoder)
        contentView = loadViewFromNib()
        addSubview(contentView)
        addConstraints()
    }
    
    func loadViewFromNib() -> UIView {
        let nib = UINib(nibName: NSStringFromClass(type(of: self)).components(separatedBy: ".").last!, bundle: Bundle(for: type(of: self)))
        let view = nib.instantiate(withOwner: self, options: nil).first as! UIView
        return view
    }
    
    func addConstraints() {
        contentView.translatesAutoresizingMaskIntoConstraints = false
        var constraint = NSLayoutConstraint(item: contentView, attribute: .leading, relatedBy: .equal, toItem: self, attribute: .leading, multiplier: 1, constant: 0)
        addConstraint(constraint)
        constraint = NSLayoutConstraint(item: contentView, attribute: .trailing, relatedBy: .equal, toItem: self, attribute: .trailing, multiplier: 1, constant: 0)
        addConstraint(constraint)
        constraint = NSLayoutConstraint(item: contentView, attribute: .top, relatedBy: .equal, toItem: self, attribute: .top, multiplier: 1, constant: 0)
        addConstraint(constraint)
        constraint = NSLayoutConstraint(item: contentView, attribute: .bottom, relatedBy: .equal, toItem: self, attribute: .bottom, multiplier: 1, constant: 0)
        addConstraint(constraint)
    }
