How to auto layout contentView?

[iOkay]

I called PKHUD show content view as follow, but content view's frame is zero, cannot show on view. How to deal with the frame of contentView without set one? Is it possible to auto layout the content View?

 let content = TipMessageView(type: type)
            content.label.text = message
            PKHUD.sharedHUD.contentView = content
            
            PKHUD.sharedHUD.show()
            PKHUD.sharedHUD.hide(afterDelay: TimeInterval(delaySec), completion: { (success) in
            
                if completion != nil {
                    DispatchQueue.main.async {
                        completion!()
                    }
                }
            })

Code of TipMessageView:

class TipMessageView: UIView {

    private var leftView: UIView = {
        let view = UIView()
        view.backgroundColor = UIColor.clear
        return view
    }()
    
    private var rightView: UIView = {
        let view = UIView()
        view.backgroundColor = UIColor.clear
        return view
    }()
    
    private var icon: UIImageView = {
        let view = UIImageView()
        view.backgroundColor = UIColor.clear
        return view
    }()
    var label: UILabel = {
        let label = UILabel()
        label.backgroundColor = UIColor.clear
        label.textAlignment = .center
        label.font = UIFont.PingFangSC_Semibold(size: 14)
        label.textColor = UIColor.white
        return label
    }()
    
    private var _type: TipMessageType = .success
    var type: TipMessageType {
        get {
            return _type
        }
        set(newValue) {
            _type = newValue
            if _type == .success {
                
                self.backgroundColor = UIColor(hexString: "#37B0CD")
                self.icon.image = UIImage(named: "tip_hud_suc")
            } else if _type == .fail {
                
                self.backgroundColor = UIColor(hexString: "#F26868")
                self.icon.image = UIImage(named: "tip_hud_fail")
            }
        }
    }
    
    init(type: TipMessageType) {
        
        //CGRect(x:0, y:0, width:204, height: 56)
        super.init(frame: CGRectZero)
        
        self.layer.cornerRadius = 4
        self.clipsToBounds = true
        
        self.addSubview(self.leftView)
        self.addSubview(self.icon)
        self.addSubview(self.label)
        self.addSubview(self.rightView)
        
        self.type = type
    }
    
    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    
    override func layoutSubviews() {
        
        super.layoutSubviews()
        
        self.leftView.snp.makeConstraints { (make) in
            
            make.left.equalTo(self)
            make.centerY.equalTo(self)
            make.width.equalTo(self.rightView)
            make.height.equalTo(1)
        }
        
        self.icon.snp.makeConstraints { (make) in
            make.centerY.equalTo(self)
            make.left.equalTo(self.leftView.snp.right)
            make.width.equalTo(19)
            make.height.equalTo(19)
        }
        
        self.label.snp.makeConstraints { (make) in
            make.centerY.equalTo(self)
            make.left.equalTo(self.icon.snp.right).offset(4)
        }
        
        self.rightView.snp.makeConstraints { (make) in
            
            make.centerY.equalTo(self)
            make.left.equalTo(self.label.snp.right)
            make.right.equalTo(self)
        }
    }
}
