【问题描述】：
当我转到我的设置视图控制器时，标签栏应该消失；但是，它并没有走一条路，而是变成黑色，覆盖了一些设置页面。这是图片（我涵盖了私人信息）：
这是我的设置控制器代码：
private let reuseIdentifier = "SettingsCell"
class SettingsViewController: UIViewController {
// MARK: - Properties
override func viewDidAppear(_ animated: Bool) {
self.navigationController?.navigationBar.prefersLargeTitles = true
}
var tableView: UITableView!
var userInfoHeader: UserInfoHeader!
var user: User?
// MARK: - Init
override func viewDidLoad() {
super.viewDidLoad()
configureUI()
}
// MARK: - Helper Functions
func configureTableView() {
tableView = UITableView()
tableView.delegate = self
tableView.dataSource = self
tableView.rowHeight = 60
tableView.register(SettingsCell.self, forCellReuseIdentifier: reuseIdentifier)
view.addSubview(tableView)
tableView.frame = CGRect(x: 0, y: 0, width: view.frame.width, height: 800)
let frame = CGRect(x: 0, y: 0, width: view.frame.width, height: 85)
userInfoHeader = UserInfoHeader(frame: frame)
userInfoHeader.usernameLabel.text = "\(user?.firstName ?? "") \(user?.lastName ?? "")"
userInfoHeader.schoolLabel.text = user?.school
if let imageUrl = user?.imageUrl1, let url = URL(string: imageUrl) {
// Nuke.loadImage(with: url, into: self.image1Button)
SDWebImageManager().loadImage(with: url, options: .continueInBackground, progress: nil) { (image, _, _, _, _, _) in
self.userInfoHeader.profileImageView.image = image
}
}
let tapRecognizer = UITapGestureRecognizer(target: self, action: #selector(goToProfile))
userInfoHeader.addGestureRecognizer(tapRecognizer)
tableView.tableHeaderView = userInfoHeader
tableView.tableFooterView = UIView()
}
@objc fileprivate func goToProfile() {
let userDetailsController = CurrentUserDetailsNoReportController()
let myBackButton = UIBarButtonItem()
myBackButton.title = " "
navigationItem.backBarButtonItem = myBackButton
userDetailsController.cardViewModel = user?.toCardViewModel()
navigationController?.pushViewController(userDetailsController, animated: true)
}
func configureUI() {
configureTableView()
// navigationController?.navigationBar.isTranslucent = false
navigationItem.title = "Settings"
navigationItem.leftBarButtonItem = UIBarButtonItem(image: #imageLiteral(resourceName: "icons8-chevron-left-30").withRenderingMode(.alwaysOriginal), style: .plain, target: self, action: #selector(handleBack))
}
@objc fileprivate func handleBack() {
dismiss(animated: true)
}
@objc fileprivate func handleSwitchNotification(sender: UISwitch) {
if sender.isOn {
showSettingsAlert(sender: sender)
}
else {
showSettingsAlert(sender: sender)
}
}
@objc fileprivate func handleSwitchLocation(sender: UISwitch) {
if sender.isOn {
showSettingsAlert2(sender: sender)
}
else {
showSettingsAlert2(sender: sender)
}
}
private func showSettingsAlert(sender: UISwitch) {
let alert = UIAlertController(title: "Notifications Permissions", message: "Change your notifications permissions?", preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "Open Settings", style: .default) { action in
UIApplication.shared.open(URL(string: UIApplication.openSettingsURLString)!)
})
alert.addAction(UIAlertAction(title: "Cancel", style: .cancel) { action in
sender.isOn = false
return
})
present(alert, animated: true)
}
private func showSettingsAlert2(sender: UISwitch) {
let alert = UIAlertController(title: "Location Permissions", message: "Change your location permissions?", preferredStyle: .alert)
alert.addAction(UIAlertAction(title: "Open Settings", style: .default) { action in
UIApplication.shared.open(URL(string: UIApplication.openSettingsURLString)!)
})
alert.addAction(UIAlertAction(title: "Cancel", style: .cancel) { action in
sender.isOn = false
return
})
present(alert, animated: true)
}
}
extension SettingsViewController: UITableViewDelegate, UITableViewDataSource {
func numberOfSections(in tableView: UITableView) -> Int {
return SettingsSection.allCases.count
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
guard let section = SettingsSection(rawValue: section) else {return 0}
switch section {
case .Social:
return SocialOptions.allCases.count
case .Communications:
return CommunicationOptions.allCases.count
case .About:
return AboutOptions.allCases.count
}
}
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return 40
}
func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let view = UIView()
view.backgroundColor = .white
let title = UILabel()
title.font = UIFont.boldSystemFont(ofSize: 22)
title.textColor = #colorLiteral(red: 0.2196078449, green: 0.007843137719, blue: 0.8549019694, alpha: 1)
title.text = SettingsSection(rawValue: section)?.description
view.addSubview(title)
title.anchor(top: view.topAnchor, leading: view.leadingAnchor, bottom: view.bottomAnchor, trailing: nil, padding: .init(top: 2, left: 10, bottom: 2, right: 0))
return view
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: reuseIdentifier, for: indexPath) as! SettingsCell
guard let section = SettingsSection(rawValue: indexPath.section) else {return UITableViewCell()}
switch section {
case .Social:
let social = SocialOptions(rawValue: indexPath.row)
cell.sectionType = social
case .Communications:
let communications = CommunicationOptions(rawValue: indexPath.row)
cell.sectionType = communications
switch communications {
case .location:
switch CLLocationManager.authorizationStatus() {
case .notDetermined, .restricted, .denied:
cell.switchControl.isOn = false
cell.switchControl.addTarget(self, action: #selector(handleSwitchLocation), for: .valueChanged)
default:
cell.switchControl.isOn = true
cell.switchControl.addTarget(self, action: #selector(handleSwitchLocation), for: .valueChanged)
}
default:
let isRegisteredForRemoteNotifications = UIApplication.shared.isRegisteredForRemoteNotifications
if isRegisteredForRemoteNotifications {
cell.switchControl.isOn = true
cell.switchControl.addTarget(self, action: #selector(handleSwitchNotification), for: .valueChanged)
} else {
cell.switchControl.isOn = false
cell.switchControl.addTarget(self, action: #selector(handleSwitchNotification), for: .valueChanged)
}
}
case .About:
let about = AboutOptions(rawValue: indexPath.row)
cell.sectionType = about
}
cell.selectionStyle = .none
return cell
}
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
guard let section = SettingsSection(rawValue: indexPath.section) else {return}
switch section {
case .Social:
let social = SocialOptions(rawValue: indexPath.row)
if social?.description == "Edit Profile" {
let settingsController = NiceEditProfile()
settingsController.user = user
let myBackButton = UIBarButtonItem()
myBackButton.title = " "
self.navigationItem.backBarButtonItem = myBackButton
self.navigationController?.pushViewController(settingsController, animated: true)
}
else if social?.description == "Logout" {
let firebaseAuth = Auth.auth()
let loginViewController = LoginViewController()
let navController = UINavigationController(rootViewController: loginViewController)
navController.modalPresentationStyle = .fullScreen
do {
try firebaseAuth.signOut()
} catch { }
present(navController, animated: true)
}
case .Communications:
let communications = CommunicationOptions(rawValue: indexPath.row)
case .About:
let about = AboutOptions(rawValue: indexPath.row)
if about?.description == "Privacy" {
let privacyCon = PrivacyController()
self.navigationController?.pushViewController(privacyCon, animated: true)
}
else if about?.description == "Terms of Use" {
let termsController = TermsViewController()
self.navigationController?.pushViewController(termsController, animated: true)
}
}
}
}
这是我到设置控制器的过渡（这个控制器有一个标签栏）
@objc func handleSettings() {
let settingsController = ViewController()
//settingsController.delegate = self
settingsController.user = user
let navController = UINavigationController(rootViewController: settingsController)
navController.modalPresentationStyle = .fullScreen
present(navController, animated: true)
}
隐藏标签栏不起作用。这似乎只发生在 iOS 13.5 之后会发生什么？
【问题讨论】：
-
"标签栏应该消失" 为什么它会消失？我没有看到任何关于标签栏的代码。
