页面控件中的多个 UILabel

Question

我正在尝试为多个 UILabel 做一个 scrollView + pageControl，即每个视图应该有 2 个 UILabel - 一个用于标题，一个用于描述。

我熟悉将单个 UILabel 添加到 scrollView + pageControl 中。问题是如何将多个 UILabel 添加到 scrollView 的子视图中？我有以下代码适用于单个 UILabel：

@IBOutlet weak var bloggerReviewScrollView: UIScrollView!
@IBOutlet weak var bloggerReviewPageControl: UIPageControl!
var frame = CGRect(x: 0, y: 0, width: 0, height: 0)
var reviews: [Reviews] = [Reviews(name: "NameA", description: "DescriptionA", date: Date.init(), url: nil), Reviews(name: "NameB", description: "DescriptionB", date: Date.init(), url: nil)]

func updateReview() {
    reviewPageControl.numberOfPages = reviews.count
    for index in 0..<reviews.count {
        frame.origin.x = reviewScrollView.frame.size.width * CGFloat(index)
        frame.size = reviewScrollView.frame.size

        let reviewContent = UILabel(frame: frame)
        reviewContent.text = reviews[index].description
        reviewContent.numberOfLines = 0
        reviewScrollView.addSubview(reviewContent)
    }
    reviewScrollView.contentSize = CGSize(width: reviewScrollView.frame.size.width * CGFloat(reviews.count), height: reviewScrollView.frame.size.height)
    reviewScrollView.delegate = self
}

但是，除了reviews[index].description，我还想在不同的标签中显示reviews[index].name，以便该标签的样式独立于视图中描述标签的样式。我有什么办法吗？

非常感谢！

您需要决定在哪里以及如何显示两个标签，即标签框架，我分为两部分，您可以根据您的要求更改框架并创建新的 Label 实例并将其添加到您的 reviewScrollView

func updateReview() {
  reviewPageControl.numberOfPages = reviews.count
  for index in 0..<reviews.count {
    frame.origin.x = reviewScrollView.frame.size.width * CGFloat(index)
    frame.size = reviewScrollView.frame.size

    //title lable
    ////set title frame based on your requirment
     let reviewLabelFrame = CGRect(x: frame.origin.x, y: 0, width: frame.width, height: frame.height/2)
    let titleLabel = UILabel(frame: reviewLabelFrame)
    titleLabel.text = reviews[index]. name // get name and set the title  
    titleLabel.numberOfLines = 0
    reviewScrollView.addSubview(titleLabel)

    //descriptions Label

    //set descriptions frame based on your requirment
    let desLableFram = CGRect(x: frame.origin.x, y: frame.height/2, width: frame.width, height: frame.height/2)
    let desLable = UILabel(frame: desLableFram)
    desLable.text = reviews[index].description //get description and set 
    desLable.numberOfLines = 0
    reviewScrollView.addSubview(desLable) //add your descriptions
}

您需要根据您的要求计算两个标签的框架
