如何在swift中创建两个搜索栏？

import UIKit

let searchBar1 = UISearchBar()
let searchBar2 = UISearchBar()

searchBar1.placeholder = "搜索栏1"
searchBar2.placeholder = "搜索栏2"

searchBar1.searchBarStyle = .default
searchBar2.searchBarStyle = .default

// 可以根据需要设置其他属性，如背景颜色、文本颜色等

searchBar1.frame = CGRect(x: 0, y: 0, width: view.frame.width, height: 50)
searchBar2.frame = CGRect(x: 0, y: 50, width: view.frame.width, height: 50)

// 这里假设搜索栏位于视图控制器的顶部，高度为50，可以根据需要进行调整

view.addSubview(searchBar1)
view.addSubview(searchBar2)
