以编程方式添加约束以防止按钮重叠SWIFT 4

Question

我想知道是否有人能以编程方式帮助我。我想要的是：

我在循环内创建按钮，并且按钮水平对齐。某些按钮的宽度不同，这意味着按钮可以与另一个按钮重叠。是否可以使用约束来防止重叠并在两者之间添加一个空白区域？

在此先感谢

代码：

 for (j, _) in buttonInfo.enumerated(){ 
     let button: UIButton = buttonArray[j] 
     let stackView = UIStackView(); 

     stackView.spacing = 30; 


     button.tag = Int((buttonInfo[j]?.pID)!)! 
     button.setTitle(buttonInfo[j]?.title, for: .normal) 
     button.addTarget(self, action: #selector(PalletViewController.productCall), for: .touchUpInside) 

     let stock = Int(buttonInfo[j]!.stock) 

     if(stock! == 0 || stock! < 0){ 
      button.isHidden = true; 
     } 


     let views = ["view": view, "button": button] as [String : Any] 





     let spacing = NSLayoutConstraint.constraints(withVisualFormat: "H:|-(10)-|", options: NSLayoutFormatOptions(rawValue: 0), metrics: nil, views: views); 

     view.addConstraints(spacing); 


    }

堆栈视图是最好的选择，可以通过编程方式也创建它。 https://developer.apple.com/library/content/documentation/UserExperience/Conceptual/AutolayoutPG/LayoutUsingStackViews.html
