推荐答案

假设情节提要中有一个简单的搜索栏，请确保已将其连接为插座.然后以这个为例. 使用UISearchBarDelegate引用了解更多信息关于可用的委托方法.

Assuming you have a simple search bar in your storyboard, make sure you have it connected as an outlet. Then use this as an example. Use UISearchBarDelegate the reference to learn more about delegate methods available to you.

import UIKit

class ViewController: UIViewController, UISearchBarDelegate {

@IBOutlet var searchBar:UISearchBar!

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        searchBar.delegate = self
    }

    func searchBar(searchBar: UISearchBar, textDidChange searchText: String) {
        print("searchText \(searchText)")
    }

    func searchBarSearchButtonClicked(searchBar: UISearchBar) {
        print("searchText \(searchBar.text)")
    }

}
