无法在iOS Swift中将HTML数据的新段落显示到Textview中

编程问答 2022-08-22

问题描述

我正在使用iOS（Swift）应用程序。我收到一些服务器响应，如下所示。

"description":"This is sample text to show in UI. When doing everyday activities.\u003cbr /\u003eclass is a strong predictor of life,and again sample text here.\u003cbr /\u003eSample text can show here also."

因此，上面的文本有3个段落，我试图在Textview中显示它们，但是用新行而不是新段落以纯文本显示。

    override func viewDidLoad() {
        super.viewDidLoad()

            let description = jsonResponse["description"] as! String
            
            self.textView.attributedText = description.htmlAttributedString()


}
    extension String {
        func htmlAttributedString() -> NSAttributedString? {
            guard let data = self.data(using: String.Encoding.utf16,allowLossyConversion: false) else { return nil }
            guard let html = try? NSMutableAttributedString(
                data: data,options: [NSAttributedString.DocumentReadingOptionKey.documentType: NSAttributedString.DocumentType.html],documentAttributes: nil) else { return nil }
            return html
        }
    }


The issue is it is showing text,But like new line showing instead of new paragraph. How to fix this?

解决方法

我已通过解决此问题，并将服务器转换为json序列化后，特殊字符代码显示为

因此，我已修复如下问题

    let description = jsonResponse["description"] as! String
    let formattedString = description.replacingOccurrences(of: "<br />",with: " \n\n")
    self.textView.text = formattedString
