页控件中的多个uilabel

uipagecontrol uilabel uiscrollview swift

我正在尝试对多个uilabel执行scrollview+pagecontrol,即每个视图应该有两个uilabel,一个用于标题,一个用于描述。

我很熟悉在scrollview+pagecontrol中添加一个uilabel。问题是如何在scrollview的子视图中添加多个uilabel?我有以下代码,对于一个uilabel可以正常工作:

@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 ,我还想显示 reviews[index].name 以使该标签的样式独立于视图中描述标签的样式。有什么办法让我这么做吗?

谢谢大家!

你需要的是决定你想在哪里和如何显示你的两个标签,也就是说标签框架,我已经分成两部分,你可以根据你的需求改变框架,创建新的标签实例并将其添加到你的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
