How can I implement this code in swift 4 or xcode 9?
// Remove hairline between navigation bar and anything below such as search bar
UINavigationBar.appearance().shadowImage = UIImage()
I want to remove navBar underline.
Don't worry copy pasting will work.
// Remove Bottom Shadow
UINavigationBar.appearance().shadowImage = UIImage()
UINavigationBar.appearance().setBackgroundImage(UIImage(), for: .default)
Please check :
self.navigationController?.navigationBar.shadowImage = UIImage()

When applying transparent image in the navigation tab bar. It's turning white instead of being transparent..
self.navigationController?.navigationBar.setBackgroundImage(UIImage(), for: .default)
self.navigationController?.navigationBar.shadowImage = UIImage()
self.navigationController?.navigationBar.tintColor = UIColor.white
Ensure that something is under the navigation bar so that it does not just become transparent showing the white background. You will need to drag uiviews under it and then add layout constraints. Otherwise, make sure you check that you have not changed the color of the navigation bar elsewhere.
Use this extension to make navigation bar transperant.
extension UINavigationController {
func transparant() {
self.navigationBar.setBackgroundImage(UIImage(), for: UIBarMetrics.default)
self.navigationBar.shadowImage = UIImage()
self.navigationBar.isTranslucent = true
self.view.backgroundColor = UIColor.clear
}
}
if you are using Navigation Controller try this:
self.navigationController?.navigationBar.setBackgroundImage(UIImage(), for: .default)
self.navigationController?.navigationBar.shadowImage = UIImage()
title = "Some Title"
if you are using UINavigationBar try this:
#IBOutlet var navBarOutlet: UINavigationBar!
override func viewDidLoad() {
super.viewDidLoad()
// navigatin bar transparent
navBarOutlet.setBackgroundImage(UIImage(),for:.default)
navBarOutlet.shadowImage=UIImage()
navBarOutlet.topItem?.title = "Some Title"
}
I have the table view with headers. Headers have only custom text and white background. Headers are pinned on top when scrolling and I want to know, is there any way how to make the background of headers translucent same as navigation bar is? With some blur effect?
Thanks for any advice!
Change the backgroundColor to .clear, add a UIVisualEffectView below the label and set the constraints to the edges. Not sure if it will mimic the behaviour of navbar by default so you would have to play around a little with the UIBlurEffect options to get the desired effect.
let blurEffectStyle = UIBlurEffectStyle.extraLight
let blurEffect = UIBlurEffect(style: blurEffectStyle)
let visualEffectView = UIVisualEffectView(effect: blurEffect)
Then add to view and set the constraints
self.navigationController?.navigationBar.isTranslucent = true
self.navigationController?.navigationBar.shadowImage = UIImage()
self.navigationController?.view.backgroundColor = UIColor.clear
self.navigationController?.navigationBar.setBackgroundImage(UIImage(), for: .default)
self.navigationController?.navigationBar.backgroundColor = UIColor.clear
In my application I am using below code to add default navigation.
self.navigationController?.navigationBar.barStyle = UIBarStyle.default
self.navigationController?.navigationBar.backgroundColor = UIColor.clear
self.navigationController?.navigationBar.isTranslucent = false
self.navigationController?.navigationBar.barTintColor = // my color
self.navigationController?.navigationBar.tintColor = // my color
self.navigationController?.navigationBar.shadowImage = UIImage()
This code works fine till iOS 10. But in iOS 11 the back icon is not in the center.
I checked other similar issues regarding view title here and here but couldn't find any solution. Thanks.
So I found this answer and I did the same.
Removing this line from AppDelegate works for me.
UIBarButtonItem.appearance().setBackButtonTitlePositionAdjustment (UIOffsetMake(0, -60), for: .default)
As you can see in the video, there is a white thin line under the navigation bar the moment i start scrolling.
It would only disappear when I would press on the searchBar (contained by my searchController, so the search bar is not added from the Storyboard). I tried a lot of different combinations in order to try to make it disappear but nothing worked.
Any help is appreciated! Thanks!

This is the code inside my viewDidLoad:
searchController.searchBar.delegate = self
searchController.dimsBackgroundDuringPresentation = false
searchController.hidesNavigationBarDuringPresentation = false
searchController.searchBar.placeholder = "Search for a recipe"
searchController.searchBar.barTintColor = navigationController?.navigationBar.barTintColor
searchController.searchBar.tintColor = UIColor.white
Try to set background color and change shadow of the navigationBar. It possibly connected with navigationBar.
self.navigationController?.navigationBar.setBackgroundImage(UIImage(), forBarMetrics: UIBarMetrics.Default)
self.navigationController?.navigationBar.shadowImage = UIImage()
Try to add this line:
searchController.searchBar.backgroundColor = navigationController?.navigationBar.barTintColor
In the file setupSearchBar()
After code fix:
You can remove that shadow below your navigation bar by the way. I have created extension for doing this:
extension UINavigationBar {
func shouldRemoveShadow(_ value: Bool) -> Void {
self.setValue(value, forKey: "hidesShadow")
}
}
So I've been desperately trying hide the navigationBar bottom border/shadow. I've gone through all the SO answers I can get, but nothing works right.
Setting navBar background and shadow image to empty uiimage does nothing:
navigationController?.navigationBar.setBackgroundImage(UIImage(named: ""), forBarPosition: UIBarPosition.Any, barMetrics: UIBarMetrics.Default)
navigationController?.navigationBar.shadowImage = UIImage(named: "")
Setting clipsToBounds or masksToBounds = true works, but I lose status bar on top and when push to next VC with same navController, I get a black status bar.
navigationController?.navigationBar.layer.masksToBounds = true
or
navigationController?.navigationBar.clipsToBounds = true
Setting in appDelegate also does not work:
UINavigationBar.appearance().backIndicatorImage = UIImage(named: "")
UINavigationBar.appearance().shadowImage = UIImage(named: "")
I'm using Swift on iOS 8. Thanks for any other suggestions!
self.navigationController?.navigationBar.shadowImage = UIImage()
self.navigationController?.navigationBar.setBackgroundImage(UIImage(), forBarMetrics: .Default)
