我想通过swift做这样的布局：

我试着用这样的方式来做：

var buttonArray = [UILabel]()
for (myKey,myValue) in colorDictionary{
   buttonArray += [colorButton(withColor: myValue, title: myKey)]
}
let horizontalStack = UIStackView(arrangedSubviews: buttonArray)
horizontalStack.axis = .horizontal
horizontalStack.distribution = .fillEqually
horizontalStack.alignment = .fill
horizontalStack.translatesAutoresizingMaskIntoConstraints = false
horizontalStack.transform = CGAffineTransform(rotationAngle: -CGFloat.pi / 2)

let label2       = UILabel()
label2.text      = "Label"
label2.backgroundColor = .red
label2.textColor = .white
label2.textAlignment = .center
label2.lineBreakMode = .byCharWrapping
label2.numberOfLines = 0
label2.translatesAutoresizingMaskIntoConstraints = false
label2.transform = CGAffineTransform(rotationAngle: -CGFloat.pi / 2)
        
let mainStackView = UIStackView()
mainStackView.axis = .horizontal
mainStackView.translatesAutoresizingMaskIntoConstraints = false
mainStackView.addArrangedSubview(label2)
mainStackView.addArrangedSubview(horizontalStack)

    mainContainer.addSubview(mainStackView)

    
    
    NSLayoutConstraint.activate([
        mainStackView.topAnchor.constraint(equalTo: mainContainer.topAnchor, constant: 5),
        mainStackView.leftAnchor.constraint(equalTo: mainContainer.leftAnchor,
                                        constant: 20),
        mainStackView.rightAnchor.constraint(equalTo: mainContainer.rightAnchor,
                                         constant: -20),
        mainStackView.heightAnchor.constraint(equalToConstant: 270),
    ])

其中colorButton为：

func colorButton(withColor color:UIColor, title:String) -> UILabel{
        let newButton = UILabel()
        newButton.backgroundColor = color
        newButton.text = title
        newButton.textAlignment = .center
        newButton.textColor = UIColor.white
        return newButton
    }

这是我得到的结果

我怎样才能使所有这些标签看起来像所需的图像？而且我也不知道是否标签旋转可以用我的方法。
