我想让它像下面的图片，但它就像上面的图片一样。
这是我的代码。
lazy var button = UIDropDownButton().then {
$0.setAction().subscribe(onNext: {
switch $0 {
case .popularity: break
// 인기순 정렬 코드
case .suggestion: break
// 추천순 정렬 코드
case .lowestPrice: break
// 최저가순 정렬 코드
}
})
.disposed(by: disposeBag)
}
lazy var barButtonItem = UIBarButtonItem(customView: button)
override func viewDidLoad() {
super.viewDidLoad()
setNavigationBar()
}
override func viewWillAppear(_ animated: Bool) {
setNavigationBar()
}
private func setNavigationBar() {
setLargeTitleNavigationBar(title: "제품")
self.navigationItem.rightBarButtonItem = barButtonItem
let searchController = UISearchController(searchResultsController: nil)
self.navigationItem.searchController = searchController
}
setLargeTitleNavigationBar 方法在这里。
extension UIViewController {
func setLargeTitleNavigationBar(title: String) {
self.navigationController?.navigationBar.prefersLargeTitles = true
self.navigationController?.setBackButon()
self.navigationController?.navigationBar.backgroundColor = nil
self.navigationController?.navigationBar.shadowImage = nil
self.navigationController?.navigationBar.setBackgroundImage(nil, for: UIBarMetrics.default)
self.navigationItem.title = title
}
我不知道如何解决这个问题。我喜欢 Snapkit，但我可以阅读故事板。
