ios - 在 Swift 3 中更改来自 JSON url 的数据的行高

Question

您好，我有一个从 JSON url 引入数据的应用程序，我正在尝试更改一些排版的行高，即 articleContentValue，此处的先前答案使用 String 作为值，但我使用的是文章结构。到目前为止，我的代码如下:

import Foundation
import UIKit

class myVC: UIViewController {

    var article: Article?

    @IBOutlet var scrollView: UIScrollView!
    @IBOutlet var mainImageView: UIImageView!
    @IBOutlet var articleTitle: UILabel!
    @IBOutlet var articleContentValue: UILabel!


    override func viewDidLoad() {
        super.viewDidLoad()

        if let article = article {

            articleTitle.text = article.name
            mainImageView.hnk_setImage(from: article.mainImage)
            articleContentValue.text = article.content

        }

        articleContentValue.textColor = UIColor(red:0.27, green:0.27, blue:0.27, alpha:1.0)

    }
}

谢谢

试试这个:

    let attributedString = NSMutableAttributedString(string: article.content)
    let paragraphStyle = NSMutableParagraphStyle()
    paragraphStyle.lineSpacing = 2 // Whatever line spacing you want in points
    attributedString.addAttribute(NSParagraphStyleAttributeName, value:paragraphStyle, range:NSMakeRange(0, attributedString.length))
    articleContentValue.attributedText = attributedString;
