我有一個使用https://newsapi.org的新聞應用程序，它使用了大約60個來源，因此目錄很長。因爲我在快速編程方面並不擅長，所以我制定了一個難以搜索的解決方案，並且我在互聯網上找不到任何解決方案。但我需要實現一個UISearchBar，否則它不是非常友好的。這些是我的兩個字符串集合，即源和URL的名稱。搜索兩個字符串集合Swift

名稱和URL位於同一IndexPath中，因此當您單擊某個名稱時，它會加載該URL。代碼如下所示：
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)
}
}
與UI，它看起來像這樣：
