我有一个使用https://newsapi.org的新闻应用程序，它使用了大约60个来源，因此目录很长。因为我在快速编程方面并不擅长，所以我制定了一个难以搜索的解决方案，并且我在互联网上找不到任何解决方案。但我需要实现一个UISearchBar，否则它不是非常友好的。这些是我的两个字符串集合，即源和URL的名称。搜索两个字符串集合Swift

名称和URL位于同一IndexPath中，因此当您单击某个名称时，它会加载该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)
}
}
与UI，它看起来像这样：
