ios - 激活 ReightViewMode 时，SearchBar 会自动将未创建的 ImageView 添加到后台

Question

我需要向 searchTextField.RightView 添加一个View ，但是当我激活RightViewMode时，会显示一个不是我创建的 ImageView （放大镜）。

我的自定义搜索条码：

override init(frame: CGRect) {
    super.init(frame: .zero)
    setupLayout()
}

override func setNeedsLayout() {
    super.setNeedsLayout()
    self.searchTextField.rightViewMode = .always
}

private func setupLayout() {
    self.searchBarStyle = UISearchBar.Style.default
    self.placeholder = "Search..."
    self.sizeToFit()
    self.isTranslucent = false
    self.returnKeyType = .search
    self.searchTextField.leftView?.tintColor = .darkText
    self.showsCancelButton = true
    
    let view = UIView()
    view.backgroundColor = .red
    view.snp.makeConstraints({ make in
        make.size.equalTo(26)
    })
    self.searchTextField.rightView = view
}

视图控制器

override func viewDidLoad() {
    super.viewDidLoad()
    
    view.addSubview(customSearchBar)
    customSearchBar.snp.makeConstraints { make in
        make.leading.trailing.equalToSuperview()
        make.height.equalTo(30)
        make.center.equalToSuperview()
    }
}
