创建函数以编程方式从Swift4中的字符串数组创建UILabels

import UIKit

func createLabels(from strings: [String]) -> [UILabel] {
    var labels: [UILabel] = []
    
    for string in strings {
        let label = UILabel()
        label.text = string
        label.textColor = .black
        label.textAlignment = .center
        label.font = UIFont.systemFont(ofSize: 16)
        labels.append(label)
    }
    
    return labels
}

// 使用示例
let stringArray = ["Hello", "World", "From", "Swift"]
let labels = createLabels(from: stringArray)

// 假设您有一个视图来添加这些标签
for label in labels {
    view.addSubview(label)
    // 设置每个标签的位置和大小
    label.frame = CGRect(x: 0, y: 0, width: 100, height: 30)
}

for (index, label) in labels.enumerated() {
    view.addSubview(label)
    label.translatesAutoresizingMaskIntoConstraints = false
    NSLayoutConstraint.activate([
        label.centerXAnchor.constraint(equalTo: view.centerXAnchor),
        label.centerYAnchor.constraint(equalTo: view.centerYAnchor, constant: CGFloat(index * 40))
    ])
}
