以編程方式添加約束以防止按鈕重疊SWIFT 4

Question

我想知道是否有人能以編程方式幫助我。我想要的是：

我在循環內創建按鈕，並且按鈕水平對齊。某些按鈕的寬度不同，這意味着按鈕可以與另一個按鈕重疊。是否可以使用約束來防止重疊並在兩者之間添加一個空白區域？

在此先感謝

代碼：

 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); 


    }

堆棧視圖是最好的選擇，可以通過編程方式也創建它。 https://developer.apple.com/library/content/documentation/UserExperience/Conceptual/AutolayoutPG/LayoutUsingStackViews.html
