ios - Swift 搜索两个字符串集合

Question

我有一个新闻应用程序，它使用 https://newsapi.org ，它使用大约 60 个源，因此目录相当长。因为我不太擅长快速编程，所以我制定了一个很难搜索的解决方案，并且在互联网上找不到任何解决方案。但我需要实现一个 UISearchBar，否则它不是很用户友好。这是我的两个字符串集合，源名称和 URL。

var sourceURL = [

名称和 URL 位于同一 IndexPath 上，因此当您单击名称时，它会加载 URL。代码如下所示:

override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return self.sourceName.count
}


override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    let cell = UITableViewCell()

    cell.textLabel?.text = sourceName[indexPath.row]

    cell.textLabel?.font = UIFont.systemFont(ofSize: 20, weight: UIFontWeightHeavy)

    cell.textLabel?.textAlignment = NSTextAlignment.center

    cell.backgroundColor = UIColor.clear

    return cell
}

override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

    if sourceURL[indexPath.row] != "" {

        sourceStruct.source = sourceURL[indexPath.row]

        sourceStruct.sourceTitle = sourceName[indexPath.row]

        let loginPageView = (self.storyboard?.instantiateViewController(withIdentifier: "NewsHome"))! as UIViewController
        self.present(loginPageView, animated: true, completion: nil)

    } else {

        let vc = UIStoryboard.init(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "ArticleWV") as! ArticleWV

        vc.url = "https://newsapi.org"

        self.present(vc, animated: true, completion: nil)

     }
}

使用 UI，它看起来像这样:

我会对每一个提示感到非常高兴，我已经在这个问题上坚持了好几个星期了。预先感谢，M.Rest

您只需要正确实现numberOfRowsInSection，以便在使用时在搜索栏中键入文本并根据搜索文本过滤数组。

下面的示例可能会有所帮助。如果您需要任何帮助，请告诉我。
