Cant hide status bar - ios

Cant hide status bar. Is it possible on iPhones with an eyebrow?
In ViewController:
...
override var prefersStatusBarHidden: Bool {
return true
}
...
override func viewDidLoad() {
super.viewDidLoad()
print(prefersStatusBarHidden) // true
}
...

Method 1: Go to Your info.plist file.
Add a key called “View controller-based status bar appearance” and set its value to NO.
Method 2: Go to your app delegate and write this line of code.
UIApplication.shared.isStatusBarHidden = true
Example:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
UIApplication.shared.isStatusBarHidden = true
return true
}

Add View controller-based status bar appearance in .plist and set it to YES.

preferredStatusBarStyle .lightContent doesn't work with Navigation Controller

preferredStatusBarStyle .lightContent doesn't work with Navigation Controller. I have tried this method below
override var preferredStatusBarStyle: UIStatusBarStyle { return .lightContent }
This is my first time to face this kind of issue. This code works in my Previous apps.
I even change this in my target:
I think you forget to change statusbar style in info.plist
Change in info.plist the row
View controller-based status bar appearance and set it to YES
and in Your ViewController:
override var preferredStatusBarStyle: UIStatusBarStyle { return .lightContent }
No other code is required
Make sure that in your Info.plist file you have View controller-based status bar appearance set to NO. It would also be helpful to check that you don't programatically set the status bar to a different color in a view controller by accident. If you're using the above function, do you call self.setNeedsStatusBarAppearanceUpdate? But you shouldn't need to write any code at all if you set Light as the value in your project settings and NO in your plist file.
Another option that has worked for me in the past is in your AppDelegate file, in the didFinishLaunchingWithOptions function do this:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
UIApplication.shared.statusBarStyle = .lightContent
return true
}

Is it possible to change Status Bar color for all view controllers?

I have been searching for a while now and I only found answers that describe to change color on one view controller not for all view controllers.
Is it possible to do it?
Only two steps are needed to change the status bar style for the entire app. 🙂
Step 1
Add a new property to the project's Info.plist file and set it to false.
<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>
Step 2
Go to your project's target and under General / Deployment Info, switch Status Bar Style from Default to Light.
Doing these steps will ensure the status bar behaves the same in the entire project.
Set the style of the status bar in AppDelegate.swift:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
UIApplication.shared.statusBarStyle = .lightContent
return true
}
And add the following code to your Info.plist:
<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>
First in info.plist set View controller-based status bar appearance to NO
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
let statusBar: UIView = UIApplication.shared.value(forKey: "statusBar") as! UIView
if statusBar.responds(to:#selector(setter: UIView.backgroundColor)) {
statusBar.backgroundColor = UIColor.blue
}
UIApplication.shared.statusBarStyle = .lightContent
return true
}
The output screenshot is below
You can set background color for status bar during application launch or during viewDidLoad of your view controller.
extension UIApplication {
var statusBarView: UIView? {
return value(forKey: "statusBar") as? UIView
}
}
// Set upon application launch, if you've application based status bar
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
UIApplication.shared.statusBarView?.backgroundColor = UIColor.red
return true
}
}
or
// Set it from your view controller if you've view controller based statusbar
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
UIApplication.shared.statusBarView?.backgroundColor = UIColor.red
}
}
Here is result:
Here is Apple Guidelines/Instruction about status bar change. Only Dark & light (while & black) are allowed in status bar.
Here is - How to change status bar style:
If you want to set status bar style, application level then set UIViewControllerBasedStatusBarAppearance to NO in your `.plist' file.
Or programatically you can do it from app delegate:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
application.statusBarStyle = .lightContent
return true
}
if you wan to set status bar style, at view controller level then follow these steps:
Set the UIViewControllerBasedStatusBarAppearance to YES in the .plist file, if you need to set status bar style at UIViewController level only.
In the viewDidLoad add function - setNeedsStatusBarAppearanceUpdate
override preferredStatusBarStyle in your view controller.
-
override func viewDidLoad() {
super.viewDidLoad()
self.setNeedsStatusBarAppearanceUpdate()
}
override var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
Set value of .plist according to status bar style setup level.
Swift 4
In AppDelegate.swift add this extension:
extension UINavigationController {
override open var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
}
Yes,
Step 1:
Open your info.plist and insert a new key named "View controller-based status bar appearance" to NO
Step 2:
Open the viewcontroller file where you want to change the statusBarStyle and put the following code in viewWillAppear(),
UIApplication.shared.statusBarStyle = .lightContent
Step 3 :
Also, implement the viewWillDisappear() method for that specific viewController and put the following lines of code,
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
UIApplication.shared.statusBarStyle = UIStatusBarStyle.default
}
All the best
Important clarification
It is very important to understand two approaches to customizing the status bar.
Is it possible to change Status Bar color for all view controllers?
Boolean answer is Yes, but, in legal way, it is so close to No that answering Yes is provocative if you need colors other that black or white.
There are two approaches when it comes to customizing Status bar appearance.
First approach – one color for whole app
In info.plist you find or create a key called
View controller-based status bar appearance
and set it to NO.
What it does? It essentially establishes a setting that says that in your application, status bar appearance is not defined individually by each view controller. This is super important to understand. This means that you have uniform setting for entire app, for all screens. This is what you needed. But. You are limited to only two settings: white and black. And there's no way you can customize it using documented API.
To set this up:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
application.statusBarStyle = .lightContent
return true
}
Second approach – individual color for each view controller
This is the opposite. To make it work, go ahead to info.plist and set
View controller-based status bar appearance
to YES
This way, whenever a new view controller is open, status bar style is set individually if you insert this implementation in each UIViewController instance you need:
override var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
You have the same as in first, set either dark or light style for statusbar.
Third approach – Hack!
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
if let statusbar = value(forKey: "statusBar") as? UIView {
statusbar.backgroundColor = UIColor.blue
}
return true
}
Why hack? If you need status bar color other than black or white. Here you use undocumented API. You get statusBar object using KVC and manually set its color. This is dirty, not legal way, but so far it's the only way to set up custom color for statusbar. It may well lead your app to being rejected. But maybe you're lucky. In order to set it once and for all, you will need to set to NO the aforementioned flag so that status bar did not initialize its style with each view controller.

Hide Status Bar In certain View controllers *Specific*

I have a very specific question concerning hiding status bar.
I incorporated the code below to easily get a status bar on every view controller, but I have a cameraViewcontroller where I don't want a status bar. I'm trying to hide the status bar.
//change the statusbar color for all view controllers
application.statusBarStyle = .lightContent
I tried using
override var prefersStatusBarHidden: Bool {
return true
}
and
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
UIApplication.shared.isStatusBarHidden = true
return true
}
but none of this seems to work. I'm new to programming and stack overflow so please help me out. I tried search for the answer but can't seem to find the answer to this particular dilemma. Your help will be much appreciated! Thank you.
its works for me perfectly.
Objective-C
-(BOOL)prefersStatusBarHidden{
return YES;
}
Swift
override var prefersStatusBarHidden: Bool {
return true
}
you should also use info.plist
"View controller-based status bar appearance" set to NO
"Status bar is initially hidden" set to YES
Can you apply below code in the CameraVC :
override var prefersStatusBarHidden: Bool {
return true
}

preferredStatusBarStyle is not working [duplicate]

This question already has answers here:
How to set Status Bar Style in Swift 3
(33 answers)
Closed 5 years ago.
I used to use setStatusBarStyle in my project and it works fine, but it is deprecated so I use preferredStatusBarStyle, that didn't work.
knowing that I've:
Call the method setNeedsStatusBarAppearanceUpdate.
Set "View controller-based status bar appearance" to NO in info.plist
Override the function
(UIStatusBarStyle)preferredStatusBarStyle
{
return UIStatusBarStyleLightContent;
}
this function is not called
Note: I'm using navigation controller.
Here is Apple Guidelines/Instruction about status bar change.
If you want to set status bar style, application level then set UIViewControllerBasedStatusBarAppearance to NO in your .plist file. And in your appdelegate > didFinishLaunchingWithOptions add following ine (programatically you can do it from app delegate).
Objective C
[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent animated:YES];
Swift
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
application.statusBarStyle = .lightContent
return true
}
if you want to set status bar style, at view controller level then follow these steps:
Set the UIViewControllerBasedStatusBarAppearance to YES in the .plist file, if you need to set status bar style at UIViewController level only.
In the viewDidLoad add function - setNeedsStatusBarAppearanceUpdate
override preferredStatusBarStyle in your view controller.
Objective C
- (void)viewDidLoad
{
[super viewDidLoad];
[self setNeedsStatusBarAppearanceUpdate];
}
- (UIStatusBarStyle)preferredStatusBarStyle
{
return UIStatusBarStyleLightContent;
}
Swift
override func viewDidLoad() {
super.viewDidLoad()
self.setNeedsStatusBarAppearanceUpdate()
}
override var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
Set value of .plist according to status bar style setup level.
You can set background color for status bar during application launch or during viewDidLoad of your view controller.
extension UIApplication {
var statusBarView: UIView? {
return value(forKey: "statusBar") as? UIView
}
}
// Set upon application launch, if you've application based status bar
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
UIApplication.shared.statusBarView?.backgroundColor = UIColor.red
return true
}
}
or
// Set it from your view controller if you've view controller based statusbar
class ViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
UIApplication.shared.statusBarView?.backgroundColor = UIColor.red
}
}
Here is result:

iOS popViewControllerAnimated black bar appear

I have two viewcontrollers.The first viewcontroller has no statusbar.
class ViewController: UIViewController {
override func prefersStatusBarHidden() -> Bool {
return true
}
}
Also I have set UIViewControllerBasedStatusBarAppearance to YES in Info.plist.
The second viewcontroller has statusbar.
class SecondViewController: UIViewController {
override func prefersStatusBarHidden() -> Bool {
return false
}
}
The relationship between them is a push segue.
The last thing is that I have set translucent property to false in application:didFinishLaunchingWithOptions: method.
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
UINavigationBar.appearance().translucent = false
UINavigationBar.appearance().barTintColor = UIColor.redColor()
return true
}
When I click back in the navigationbar,there is a black bar.How can I get rid of it?When I set translucent to true,the black bar is gone.
After reading the post Explaining difference between automaticallyAdjustsScrollViewInsets, extendedLayoutIncludesOpaqueBars, edgesForExtendedLayout in iOS7,I have figured out a solution.
Set extendedLayoutIncludesOpaqueBars to true.
func viewDidLoad() {
extendedLayoutIncludesOpaqueBars = true // property introduced in iOS7,default value is false
}
