获取Swift中搜索栏的信息(Get informations on Search bar in Swift)

获取Swift中搜索栏的信息(Get informations on Search bar in Swift)

我有这个代码：

import UIKit class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() reload() } private func reload() { let requestUrl = "https://www.themoviedb.org/search/remote/multi?query=(XXXXXX)&language=en"

用户将在搜索栏中写入（XXXXXX）。

如何从搜索栏中捕获并转换为字符串？

I have this code :

import UIKit class ViewController: UIViewController { override func viewDidLoad() { super.viewDidLoad() reload() } private func reload() { let requestUrl = "https://www.themoviedb.org/search/remote/multi?query=(XXXXXX)&language=en"

The user will write the (XXXXXX) in search bar.

How Can I catch this from search bar and transform into a string ?

最满意答案

从xib / storyboard，通过创建这样的IBOutlet来获取搜索栏的引用

@IBOutlet weak var searchBar:UISearchBar!

您可以实现各种委托方法来观察文本中的更改和/或只需执行searchBar.text来访问用户输入的文本。

From the xib/storyboard, get the reference of the searchbar by creating an IBOutlet like so

@IBOutlet weak var searchBar:UISearchBar!

You can implement various delegate methods to observe the changes in the text and/or simply do searchBar.text to access the text entered b the user.
