如何将数组中的项写入UILabel？

import UIKit

class ViewController: UIViewController {
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let myArray = ["苹果", "香蕉", "橙子"]
        
        let label = UILabel(frame: CGRect(x: 100, y: 100, width: 200, height: 50))
        label.textAlignment = .center
        label.textColor = .black
        
        // 将数组中的项转换为字符串并赋值给UILabel的text属性
        label.text = myArray.joined(separator: ", ")
        
        self.view.addSubview(label)
    }
}
