Question

我想知道是否有人可以通过编程限制来帮助我。我想要的是：

我在循环内创建按钮，按钮水平对齐。某些按钮具有不同的宽度，因此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其间添加空格？

提前致谢

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);


    }

堆栈视图是最佳选择，您也可以通过编程方式创建它。 https://developer.apple.com/library/content/documentation/UserExperience/Conceptual/AutolayoutPG/LayoutUsingStackViews.html
