[Swift] 검색창(UISearchBar) custom programmatically , SnapKit 사용

뇽안
제가 아래와 같은 화면을 구현하고 싶었어요

(👆피그마 화면임)

그래서 UISearchBar를 통해 커스텀을 해줬습니다.

searchBar.setImage(UIImage(named: "search_back"), for: .search, state: .normal)

이렇게 search 부분에 제가 원하는 back 이미지를 넣구 타입을 .search 로 해주면
왼쪽 leftView에 디폴트인 검색 이미지가 아니라 원하는 이미지가 들어가요

근데 🤔 이거를 클릭하면 pop이 되어야하는디,,

클릭 어케하는지 아시는분~?~?

일단 전체 코드는 이러했습니뎅

import SnapKit
import UIKit

public class SearchBarView: UIView {
    public let searchBar = UISearchBar()
    
    override init(frame: CGRect) {
        super.init(frame: frame)
        
        setupView()
    }
    
    required init?(coder: NSCoder) {
        super.init(coder: coder)
    }
    
    private func setupView() {
        backgroundColor = .white
        searchBar.delegate = self
        searchBar.clipsToBounds = true
        searchBar.layer.cornerRadius = 4
        searchBar.layer.borderColor = UIColor(red: 0.902, green: 0.902, blue: 0.902, alpha: 1).cgColor
        searchBar.layer.borderWidth = 1
        
        searchBar.placeholder = "왼쪽 버튼을 어떻게 누를까 ?"
        searchBar.setImage(UIImage(named: "search_back"), for: .search, state: .normal)
        searchBar.setImage(UIImage(named: "search_cancel"), for: .clear, state: .normal)
        
        if let textfield = searchBar.value(forKey: "searchField") as? UITextField {
            textfield.attributedPlaceholder = NSAttributedString(string: textfield.placeholder ?? "", attributes: [NSAttributedString.Key.foregroundColor : UIColor(named: "gr-d") ?? .lightGray, NSAttributedString.Key.font : UIFont.NotoSansKR(type: .Regular, size: 15)])
            textfield.tintColor = UIColor(named: "yp-m")
            textfield.textColor = UIColor(named: "bk")
            textfield.font = UIFont.NotoSansKR(type: .Regular, size: 15)
            textfield.backgroundColor = .white
            if let leftView = textfield.leftView as? UIImageView {
                leftView.image = leftView.image?.withRenderingMode(.alwaysTemplate)
            }
            
            if let rightView = textfield.rightView as? UIImageView {
                rightView.image = rightView.image?.withRenderingMode(.alwaysTemplate)
            }
            
        }
        
        addSubview(searchBar)
        searchBar.snp.makeConstraints {
            $0.top.equalToSuperview().offset(6)
            $0.bottom.equalToSuperview().inset(16)
            $0.leading.equalToSuperview().offset(16)
            $0.trailing.equalToSuperview().inset(16)
        }
    }
}

저는 일단 leftView를 없애구 imageView를 넣어서 해결?을 했습니다..
이게 맞나.. 모르겠지만 얼렁뚱땅 해결쓰
