I am trying to implement XLPagerTabStrip in my application. All is good because I have followed the official Tutorial I have changed the color of my collectionView to red. When the app runs in the simulator I see that there is a blank space like image
I want to know how to remove that blank space? because it should be all red and how can I change the black line color?
this is my code:
override func viewDidLoad() {
super.viewDidLoad()
settings.style.buttonBarBackgroundColor = .red
settings.style.buttonBarItemBackgroundColor = .red
settings.style.selectedBarBackgroundColor = purpleInspireColor
settings.style.buttonBarItemFont = UIFont.systemFont(ofSize: 12, weight: UIFont.Weight.regular)
settings.style.selectedBarHeight = 0.5
settings.style.buttonBarMinimumLineSpacing = 0
settings.style.buttonBarItemTitleColor = .white
settings.style.buttonBarItemsShouldFillAvailiableWidth = true
settings.style.buttonBarLeftContentInset = 0
settings.style.buttonBarRightContentInset = 0
changeCurrentIndexProgressive = { [weak self] (oldCell: ButtonBarViewCell?, newCell: ButtonBarViewCell?, progressPercentage: CGFloat, changeCurrentIndex: Bool, animated: Bool) -> Void in
guard changeCurrentIndex == true else { return }
oldCell?.label.textColor = .white
newCell?.label.textColor = self?.purpleInspireColor
}
}
I solved my problem I forgot that this line super.viewDidLoad() should be at last of viewDidload method

I have implemented a feature, when you press on a UITabBar icon and viewController1 scrolls up using its UIScrollView. It works perfectly, but if I scroll view down and stop somewhere, then switch to another viewController2, then get back to viewController1 and press tabBar icon - the viewController1 will scroll up, but Large Title will never be showed, and I should press tabBar icon one more time to show it:
The code I use for scroll up the VC1:
private var biggestTopSafeAreaInset: CGFloat = 0
override func viewSafeAreaInsetsDidChange() {
super.viewSafeAreaInsetsDidChange()
self.biggestTopSafeAreaInset = max(view.safeAreaInsets.top, biggestTopSafeAreaInset)
}
func tabBarController(_ tabBarController: UITabBarController, didSelect viewController: UIViewController) {
if tabBarController.selectedIndex == 0 {
let navigationVC = viewController as? UINavigationController
let firstVC = navigationVC?.viewControllers.first as? CurrencyViewController
guard let scrollView = firstVC?.view.subviews.first(where: { $0 is UIScrollView }) as? UIScrollView else { return }
if traitCollection.verticalSizeClass == .compact {
scrollView.setContentOffset(CGPoint(x: 0, y: -view.safeAreaInsets.top, animated: true)
} else {
scrollView.setContentOffset(CGPoint(x: 0, y: -biggestTopSafeAreaInset, animated: true)
}
}
}
I tried to track biggestTopSafeAreaInset in different stages of VC1 life, but it always has the same number - 196.0. But then why it doesn't scroll till the Large Title after viewControllers switch?
in your tableView set contentInsetAdjustmentBehavior to never
tableView.contentInsetAdjustmentBehavior = .never
in controller update the ui of navigation bar again
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
DispatchQueue.main.async { [weak self] in
self?.navigationController?.navigationBar.sizeToFit()
}
}
here is the navigation controller
class BaseNavigationController: UINavigationController {
override func viewDidLoad() {
super.viewDidLoad()
if #available(iOS 15.0, *) {
let scrollAppearance = UINavigationBarAppearance()
scrollAppearance.shadowColor = .white
scrollAppearance.backgroundColor = .white
let navigationBarAppearance = UINavigationBarAppearance()
navigationBarAppearance.configureWithDefaultBackground()
navigationBarAppearance.backgroundColor = .white
navigationBarAppearance.largeTitleTextAttributes = [
NSAttributedString.Key.font: UIFont.systemFont(ofSize: 26),
NSAttributedString.Key.foregroundColor: UIColor.black
]
navigationBarAppearance.titleTextAttributes = [
NSAttributedString.Key.font: UIFont.systemFont(ofSize: 17),
NSAttributedString.Key.foregroundColor: UIColor.black
]
UINavigationBar.appearance().backIndicatorImage = UIImage(named: "back-arrow")
UINavigationBar.appearance().standardAppearance = navigationBarAppearance
UINavigationBar.appearance().compactAppearance = navigationBarAppearance
UINavigationBar.appearance().scrollEdgeAppearance = scrollAppearance
navigationBar.tintColor = .black
navigationBar.prefersLargeTitles = true
navigationBar.isTranslucent = false
navigationItem.largeTitleDisplayMode = .automatic
} else {
navigationBar.largeTitleTextAttributes = [
NSAttributedString.Key.font: UIFont.systemFont(ofSize: 26),
NSAttributedString.Key.foregroundColor: UIColor.black
]
navigationBar.titleTextAttributes = [
NSAttributedString.Key.font: UIFont.systemFont(ofSize: 17),
NSAttributedString.Key.foregroundColor: UIColor.black
]
navigationBar.tintColor = .black
navigationBar.prefersLargeTitles = true
navigationBar.isTranslucent = false
navigationItem.largeTitleDisplayMode = .automatic
navigationBar.barTintColor = .white
}
}
override var preferredStatusBarStyle: UIStatusBarStyle {
return .darkContent
}
}
here is the Tabbar Controller
class TabbarController:UITabBarController {
override func viewDidLoad() {
super.viewDidLoad()
let c1 = C1()
let c2 = C2()
let c3 = C3()
c1.tabBarItem = UITabBarItem(title: "Home", image: UIImage(named: "home786"), tag: 0)
c1.tabBarItem.tag = 0
let nav1 = BaseNavigationController(rootViewController: c1)
c2.tabBarItem = UITabBarItem(title: "Setting", image: UIImage(named: "home786"), tag: 0)
c2.tabBarItem.tag = 1
let nav2 = BaseNavigationController(rootViewController: c2)
c2.tabBarItem = UITabBarItem(title: "User", image: UIImage(named: "home786"), tag: 0)
c2.tabBarItem.tag = 2
let nav3 = BaseNavigationController(rootViewController: c3)
viewControllers = [nav1,nav2,nav3]
selectedViewController = nav1
tabBarController?.viewControllers?.first?.view.backgroundColor = .red
}
}
Try to add this in viewDidLoad:
view.addSubview(UIView())
this single line block large title navigation Bar... I don't Know why, but this trick fix momentarily the issue...
After some research I found out what can fix my problem. If you call this method with a small delay in tabBarController didSelect then it will be possible to see a Large Title after switching viewControllers. But I still can't figure out exactly why it happened...
DispatchQueue.main.asyncAfter(deadline: .now() + 0.2) {
navigationVC?.navigationBar.sizeToFit()
}
I feel like I’m taking crazy pills. I want to change the color of the textfield within a UISearchBar, which is hosted in a UINavigationBar. The problem I’m having is that the UISearchBar gets the color of the UINavigationBar but the TextField doesn’t change color. I’ve tried several solutions here, but none of them seem to solve the issue. Any ideas how to change the TextField’s color?
I know there are other questions out there similar to this but I’ve tried every possible solution I’ve come across and haven’t found one that solves my issue.
Current Code:
let sc = UISearchController(searchResultsController: nil)
sc.delegate = self
let scb = sc.searchBar
scb.tintColor = UIColor.green
scb.barTintColor = UIColor.yellow
if let textfield = scb.value(forKey: "searchField") as? UITextField {
textfield.textColor = UIColor.blue
if let backgroundview = textfield.subviews.first {
// Background color
backgroundview.backgroundColor = UIColor.red
// Rounded corner
backgroundview.layer.cornerRadius = 5;
backgroundview.clipsToBounds = true;
}
}
navigationController?.navigationBar.barTintColor = UIColor.blue
navigationItem.searchController = sc
navigationItem.hidesSearchBarWhenScrolling = false
I’ve created a sample project to show it in action. Any help or guidance would be greatly appreciated!
Maybe the best solution is for creating an extension for UISearchBar if you want to use these settings in more controllers. Here are some example.
extension UISearchBar {
private func getViewElement<T>(type: T.Type) -> T? {
let svs = subviews.flatMap { $0.subviews }
guard let element = (svs.filter { $0 is T }).first as? T else { return nil }
return element
}
func getSearchBarTextField() -> UITextField? {
return getViewElement(type: UITextField.self)
}
func setTextColor(color: UIColor) {
if let textField = getSearchBarTextField() {
textField.textColor = color
}
}
func setTextFieldColor(color: UIColor) {
if let textField = getViewElement(type: UITextField.self) {
switch searchBarStyle {
case .minimal:
textField.layer.backgroundColor = color.cgColor
textField.layer.cornerRadius = 6
case .prominent, .default:
textField.backgroundColor = color
#unknown default:
print("something")
}
}
}
func setPlaceholderTextColor(color: UIColor) {
if let textField = getSearchBarTextField() {
textField.attributedPlaceholder = NSAttributedString(string: self.placeholder != nil ? self.placeholder! : "", attributes: [NSAttributedString.Key.foregroundColor: color])
}
}
func setTextFieldClearButtonColor(color: UIColor) {
if let textField = getSearchBarTextField() {
let button = textField.value(forKey: "clearButton") as! UIButton
if let image = button.imageView?.image {
button.setImage(image.transform(withNewColor: color), for: .normal)
}
}
}
func setSearchImageColor(color: UIColor) {
if let imageView = getSearchBarTextField()?.leftView as? UIImageView {
imageView.image = imageView.image?.transform(withNewColor: color)
}
}
}
Update:
Change navigationItem.searchController = sc to navigationItem.titleView = sc.searchBar.
am using XLpagertabstrip in my application .. but i have a problem that the text is bigger than the width and it got cut from both sides .. like image below:
as you can see last tab which is المواجهات المباشرة is not displayed fully..
this is my code:
override func viewDidLoad() {
super.viewDidLoad()
containerView.isScrollEnabled = false
containerView.delegate = self
self.settings.style.buttonBarBackgroundColor = UIColor.clear
self.settings.style.buttonBarItemBackgroundColor = UIColor.clear
self.settings.style.selectedBarBackgroundColor = UIColor.clear
self.settings.style.buttonBarItemFont = .boldSystemFont(ofSize: 7)
self.settings.style.selectedBarHeight = 1.0
self.settings.style.buttonBarMinimumLineSpacing = 0.1
self.settings.style.buttonBarItemTitleColor = UIColor.white
self.settings.style.buttonBarItemsShouldFillAvailableWidth = true
self.settings.style.buttonBarLeftContentInset = 0
self.settings.style.buttonBarRightContentInset = 0
self.settings.style.selectedBarHeight = 1.0
changeCurrentIndexProgressive = { [weak self] (oldCell: ButtonBarViewCell?, newCell: ButtonBarViewCell?, progressPercentage: CGFloat, changeCurrentIndex: Bool, animated: Bool) -> Void in
guard changeCurrentIndex == true else { return }
//oldCell?.label.adjustsFontSizeToFitWidth = true
//newCell?.label.adjustsFontSizeToFitWidth = true
oldCell?.label.textColor = UIColor.white
newCell?.label.textColor = UIColor.white
oldCell?.label.font = UIFont(name: "AJannatLT", size: 14)!
newCell?.label.font = UIFont(name: "AJannatLT", size: 14)
newCell?.label.lineBreakMode = .byCharWrapping
oldCell?.label.lineBreakMode = .byCharWrapping
self?.buttonBarView.selectedBar.backgroundColor = UIColor.white
}
getMatchInfo()
self.navigationController?.navigationBar.topItem?.title = " "
// Do any additional setup after loading the view.
}
but this will only change it's font size if i tabbed it ...
how to solve this? i want it from the start to be fully displayed and fit cell's width ..
but i have a problem that the text is bigger than the width and it got cut from both side
You can try lineBreakMode
label.lineBreakMode = .ByCharWrapping
Read more about LineBreakMode.
I am in process of adding large title in navigation bar in one of the application. The issue is title is little long so I will require to add two lines in large title. How can I add large title with two lines in navigation bar?
This is not about default navigation bar title! This is about large title which is introduced in iOS 11. So make sure you add suggestions by considering large title. Thanks
Based in #krunal answer, this is working for me:
extension UIViewController {
func setupNavigationMultilineTitle() {
guard let navigationBar = self.navigationController?.navigationBar else { return }
for sview in navigationBar.subviews {
for ssview in sview.subviews {
guard let label = ssview as? UILabel else { break }
if label.text == self.title {
label.numberOfLines = 0
label.lineBreakMode = .byWordWrapping
label.sizeToFit()
UIView.animate(withDuration: 0.3, animations: {
navigationBar.frame.size.height = 57 + label.frame.height
})
}
}
}
}
In the UIViewController:
override func viewDidLoad() {
super.viewDidLoad()
self.title = "This is a multiline title"
setupNavigationMultilineTitle()
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
setupNavigationMultilineTitle()
}
And for setting font and color on the large title:
navigation.navigationBar.largeTitleTextAttributes = [NSAttributedStringKey.foregroundColor: .red, NSAttributedStringKey.font: UIFont.boldSystemFont(ofSize: 30)]
Get a navigation item subviews and locate UILabel from it.
Try this and see:
self.navigationController?.navigationBar.prefersLargeTitles = true
self.navigationController?.navigationItem.largeTitleDisplayMode = .automatic
self.title = "This is multiline title for navigation bar"
self.navigationController?.navigationBar.largeTitleTextAttributes = [
NSAttributedStringKey.foregroundColor: UIColor.black,
NSAttributedStringKey.font : UIFont.preferredFont(forTextStyle: .largeTitle)
]
for navItem in(self.navigationController?.navigationBar.subviews)! {
for itemSubView in navItem.subviews {
if let largeLabel = itemSubView as? UILabel {
largeLabel.text = self.title
largeLabel.numberOfLines = 0
largeLabel.lineBreakMode = .byWordWrapping
}
}
}
Here is result:
The linebreak solution seems to be problematic when there's a back button. So instead of breaking lines, I made the label auto adjust font.
func setupLargeTitleAutoAdjustFont() {
guard let navigationBar = navigationController?.navigationBar else {
return
}
// recursively find the label
func findLabel(in view: UIView) -> UILabel? {
if view.subviews.count > 0 {
for subview in view.subviews {
if let label = findLabel(in: subview) {
return label
}
}
}
return view as? UILabel
}
if let label = findLabel(in: navigationBar) {
if label.text == self.title {
label.adjustsFontSizeToFitWidth = true
label.minimumScaleFactor = 0.7
}
}
}
Then it needs to be called in viewDidLayoutSubviews() to make sure the label can be found, and we only need to call it once:
private lazy var setupLargeTitleLabelOnce: Void = {[unowned self] in
if #available(iOS 11.0, *) {
self.setupLargeTitleAutoAdjustFont()
}
}()
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
let _ = setupLargeTitleLabelOnce
}
If there's any navigationController pop event back to this controller, we need to call it again in viewDidAppear(). I haven't found a better solution for this - there's a small glitch of label font changing when coming back from a pop event:
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
if #available(iOS 11.0, *) {
setupLargeTitleAutoAdjustFont()
}
}
You could try:
Create a custom UINavigationController
Add the protocol UINavigationBarDelegate to the class definition
Override the function navigationBar(_:shouldPush:)
Activate two lines mode using hidden variable item.setValue(true, forKey: "__largeTitleTwoLineMode")
Make navigationController.navigationBar.prefersLargeTitles = true
(Edit 7/13: I notice that this solution is not support scrollView, so now I'm in research)
I found a perfect solution on Swift5
but sorry for my poor English because I'm Japanese🇯🇵Student.
In case of 2 lines In case of 3 lines
At first, set navigation settings for largeTitle normally in viewDidLoad
//Set largeTitle
navigationItem.largeTitleDisplayMode = .automatic
navigationController?.navigationBar.prefersLargeTitles = true
navigationController?.navigationBar.largeTitleTextAttributes = [.font: UIFont.systemFont(ofSize: (fontSize + margin) * numberOfLines)]//ex) fontSize=26, margin=5, numberOfLines=2
//Set title
title = "multiple large\ntitle is working!"
It is most important point of this solution that font-size at largeTitleTextAttributes equals actual font-size(+margin) multiplied by number of lines.
Description image
Because, default specification of navigationBar attributes may be able to display only 1 line largeTitle.
Although, somehow, I did notice that in case of label-settings(the label which subview of subview of navigationBar) on direct, it can display any number of lines in 1 line of in case of navigationBar attributes.
So, we should do set big font in navigationbar attributes, and set small font in the label(subview of subview of navigationBar), and take into consideration the margins.
Do label settings direct in viewDidAppear like this:
//Find label
navigationController?.navigationBar.subviews.forEach({ subview in
subview.subviews.forEach { subsubview in
guard let label: UILabel = subsubview as? UILabel else { return }
//Label settings on direct.
label.text = title
label.font = UIFont.systemFont(ofSize: fontSize)
label.numberOfLines = 0
label.lineBreakMode = .byWordWrapping
label.sizeToFit()
}
})
Therefore, in short, the solution at minimum code is given like this:
import UIKit
class ViewController: UIViewController {
private let fontSize: CGFloat = 26, margin: CGFloat = 5
private let numberOfLines: CGFloat = 2
override func viewDidLoad() {
super.viewDidLoad()
setUpNavigation()
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
setMultipleLargeTitle()
}
private func setUpNavigation() {
//Set largeTitle
navigationItem.largeTitleDisplayMode = .automatic
navigationController?.navigationBar.prefersLargeTitles = true
navigationController?.navigationBar.largeTitleTextAttributes = [.font: UIFont.systemFont(ofSize: (fontSize + margin) * numberOfLines)]
//Set title
title = "multiple large\ntitle is working!"
}
private func setMultipleLargeTitle() {
//Find label
navigationController?.navigationBar.subviews.forEach({ subview in
subview.subviews.forEach { subsubview in
guard let label: UILabel = subsubview as? UILabel else { return }
//Label settings on direct.
label.text = title
label.font = UIFont.systemFont(ofSize: fontSize)
label.numberOfLines = 0
label.lineBreakMode = .byWordWrapping
label.sizeToFit()
}
})
}
}
thank you for reading :)
Swift 4 : Multi line even though the sentence is only short
title = "You're \nWelcome"
for navItem in(self.navigationController?.navigationBar.subviews)! {
for itemSubView in navItem.subviews {
if let largeLabel = itemSubView as? UILabel {
largeLabel.text = self.title
largeLabel.numberOfLines = 0
largeLabel.lineBreakMode = .byWordWrapping
}
}
}
If anyone looking for Title Lable Not Large Title, then below code is working.
Swift 5.X
func setMultilineNavigationBar(topText: String, bottomText : String) {
let topTxt = NSLocalizedString(topText, comment: "")
let bottomTxt = NSLocalizedString(bottomText, comment: "")
let titleParameters = [NSAttributedString.Key.foregroundColor : UIColor.white,
NSAttributedString.Key.font : UIFont.systemFont(ofSize: 16, weight: .semibold)]
let subtitleParameters = [NSAttributedString.Key.foregroundColor : UIColor.white,
NSAttributedString.Key.font : UIFont.systemFont(ofSize: 13, weight: .regular)]
let title:NSMutableAttributedString = NSMutableAttributedString(string: topTxt, attributes: titleParameters)
let subtitle:NSAttributedString = NSAttributedString(string: bottomTxt, attributes: subtitleParameters)
title.append(NSAttributedString(string: "\n"))
title.append(subtitle)
let size = title.size()
let width = size.width
guard let height = navigationController?.navigationBar.frame.size.height else {return}
let titleLabel = UILabel(frame: CGRect.init(x: 0, y: 0, width: width, height: height))
titleLabel.attributedText = title
titleLabel.numberOfLines = 0
titleLabel.textAlignment = .center
self.navigationItem.titleView = titleLabel
}
SWIFT 5 This UIViewController extension helped me. Scenario that I have is mixed with enabling and disabling large titles so FIRST ENABLE large title and then call this method. Call it in viewDidLoad, I have found bug with peeking back with swipe and then releasing touch, for some reason current navigation title become previous navigation title
extension UIViewController {
/// Sets two lines for navigation title if needed
/// - Parameter animated: used for changing titles on one controller,in that case animation is off
func multilineNavTitle(_ animated:Bool = true) {
if animated {
// setting initial state for animation of title to look more native
self.navigationController?.navigationBar.transform = CGAffineTransform.init(translationX: .screenWidth/2, y: 0)
self.navigationController?.navigationBar.alpha = 0
}
//Checks if two lines is needed
if self.navigationItem.title?.forTwoLines() ?? false {
// enabling multiline
navigationItem.setValue(true,
forKey: "__largeTitleTwoLineMode")
} else {
// disabling multiline
navigationItem.setValue(false,
forKey: "__largeTitleTwoLineMode")
}
// laying out title without animation
UIView.performWithoutAnimation {
self.navigationController?.navigationBar.layoutSubviews()
self.navigationController?.view.setNeedsLayout()
self.navigationController?.view.layoutIfNeeded()
}
if animated {
//animating title
UIView.animate(withDuration: 0.3) {
self.navigationController?.navigationBar.transform = CGAffineTransform.identity
self.navigationController?.navigationBar.alpha = 1
}
}
}
}
fileprivate extension String {
/// Checks if navigation title is wider than label frame
/// - Returns: `TRUE` if title cannot fit in one line of navigation title label
func forTwoLines() -> Bool {
let fontAttributes = [NSAttributedString.Key.font: SomeFont]
let size = self.size(withAttributes: fontAttributes)
return size.width > CGFloat.screenWidth - 40 //in my case
}
}
Just create a custom navigation controller. Rest will be handled by the OS itself
class MyNavigationViewController: UINavigationController {
override func viewDidLoad() {
super.viewDidLoad()
navigationBar.delegate = self
}
}
extension MyNavigationViewController: UINavigationBarDelegate {
func navigationBar(_ navigationBar: UINavigationBar, shouldPush item: UINavigationItem) -> Bool {
item.setValuesForKeys([
"__largeTitleTwoLineMode": true
])
return true
}
}
viewController.navigationItem
.setValuesForKeys(["__largeTitleTwoLineMode": true])
WARNING: This method does not work on older OS versions
I am setting a custom view as titleView of the navigation. When viewcontroller appear its title view comes at left side for a moment and then move to center,what could be wrong? I am using the following code
let itemImgs: [UIImage] = [UIImage(named: "MORE_Location")!, UIImage(named: "MORE_Department")!, UIImage(named: "By_Teams")!, UIImage(named: "MORE_Status")!]
self.navigationController?.navigationBar.isTranslucent = false
self.navigationController?.navigationBar.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.white]
menuView = BTNavigationDropdownMenu(navigationController: self.navigationController, containerView: self.navigationController!.view, title: AppMessage.EDEmployeePeople, items: items as [AnyObject], itemImgs: itemImgs)
menuView.cellHeight = 60
menuView.cellBackgroundColor = UIColor.red
menuView.cellSelectionColor = UIColor.clear
menuView.cellSeparatorColor = UIColor.clear
menuView.shouldKeepSelectedCellColor = false
menuView.cellTextLabelColor = UIColor.white
menuView.shouldChangeTitleText = false
menuView.cellTextLabelFont = UIFont(name: "Helvetica", size: 17)
if appNeedsAutoResize
{
menuView.cellTextLabelFont = UIUtils.getFontForApproprieteField(.subHeadline).font
}
menuView.cellTextLabelAlignment = .left // .Center // .Right // .Left
menuView.arrowPadding = 15
menuView.animationDuration = 0.5
menuView.maskBackgroundColor = UIColor.clear
menuView.maskBackgroundOpacity = 0.3
menuView.didSelectItemAtIndexHandler = {(indexPath: Int) -> () in
print("Did select item at index: \(indexPath)")
if indexPath == 3
{
let byStatusViewController = ByStatusViewController(nibName: "ByStatusViewController", bundle: nil)
//UIUtils.pushViewWhenHideBottom(self, anotherVC: byStatusViewController)
self.navigationController?.pushViewController(byStatusViewController, animated: true)
}
else
{
let dropVC = DepartmentViewController(nibName: "DepartmentViewController", bundle: nil)
switch indexPath
{
case 0:
dropVC.employeeGroupInfo = EmployeeGroupInfo.locationInfo
break
case 1:
dropVC.employeeGroupInfo = EmployeeGroupInfo.departmentInfo
break
default:
dropVC.employeeGroupInfo = EmployeeGroupInfo.teamInfo
break
}
// UIUtils.pushViewWhenHideBottom(self, anotherVC: dropVC)
self.navigationController?.pushViewController(dropVC, animated: true)
}
}
self.navigationItem.titleView = menuView
}
Try to add constraints of autoresizing masks to your menu view to keep the view centered.
E.g.
menuView.autoresizingMask = [.flexibleLeftMargin, .flexibleRightMargin, .flexibleTopMargin, .flexibleBottomMargin]
I had this problem and changing my function that customize my navigationItem from viewWillAppear() to viewDidLoad() resolved
