您可以按照您所写的 “我要寻找的功能” 列表进行操作...
1.时间戳和已验证徽章在任何时候都不得缩小。

// don't let Timestamp compress
 timeStampLabel.setContentCompressionResistancePriority(.required, for: .horizontal)

 // don't let "Dot" compress
 dotLabel.setContentCompressionResistancePriority(.required, for: .horizontal)

 // badge image view is square (1:1 ratio)
 //  Width Anchor prevents both compression and expansion
 badgeImageView.widthAnchor.constraint(equalTo: badgeImageView.heightAnchor).isActive = true

1.如果UIStackView未填满宽度，则时间戳必须占用剩余空间

// don't let Display Name, Handle or Dot expand Horizontally
 displayNameLabel.setContentHuggingPriority(.required, for: .horizontal)
 handleLabel.setContentHuggingPriority(.required, for: .horizontal)
 dotLabel.setContentHuggingPriority(.required, for: .horizontal)

1.手柄将首先收缩

// Handle shrink first
 handleLabel.setContentCompressionResistancePriority(.defaultLow, for: .horizontal)

1.显示名称将最后缩小

// Display Name shrink next
 displayNameLabel.setContentCompressionResistancePriority(.defaultLow + 1, for: .horizontal)

1.你没说具体是谁，所以...

// Handle *could* to shrink to "no width"
 //  so use a min-Width to show at least a char or two
 // if you want to allow it to disappear, comment out this line
 handleLabel.widthAnchor.constraint(greaterThanOrEqualToConstant: 24.0).isActive = true

下面是一个完整的例子--它有两个按钮......一个用于循环浏览一些样本数据，另一个用于切换标签的背景颜色以查看它们的框架。stackView被添加到主视图中，但当它在单元格中使用时（我假设是这样），它的工作方式是相同的：

class TwitLineVC: UIViewController {

    let displayNameLabel = UILabel()
    let badgeImageView = UIImageView()
    let handleLabel = UILabel()
    let dotLabel = UILabel()
    let timeStampLabel = UILabel()
    
    let sampleData: [[String]] = [
        ["Stack Overflow", "@StackOverflow", "Nov 13"],
        ["Longer Display Name", "@LongerHandle", "Nov 14"],
        ["Much Longer Display Name", "@ThisHandleWillCompress", "Nov 15"],
        ["Much Longer Display Name Will Also Compress", "@ThisHandleWillCompress", "Nov 16"],
    ]
    var idx: Int = 0
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        view.backgroundColor = .black
        
        guard let img = UIImage(named: "twcheck") else {
            fatalError("Could not load image!")
        }
        badgeImageView.image = img
        
        let stackView = UIStackView()
        stackView.spacing = 4
        
        stackView.translatesAutoresizingMaskIntoConstraints = false
        view.addSubview(stackView)
        
        let g = view.safeAreaLayoutGuide
        NSLayoutConstraint.activate([

            stackView.trailingAnchor.constraint(equalTo: g.trailingAnchor, constant: -20.0),
        ])

        // don't let Display Name, Handle or Dot expand Horizontally
        displayNameLabel.setContentHuggingPriority(.required, for: .horizontal)
        handleLabel.setContentHuggingPriority(.required, for: .horizontal)

        // Handle shrink first
        handleLabel.setContentCompressionResistancePriority(.defaultLow, for: .horizontal)

        displayNameLabel.setContentCompressionResistancePriority(.defaultLow + 1, for: .horizontal)
