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
}

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.
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.
I have a custom UIWindow that is my own status bar, so I want to hide the status bar and show mine instead. I have
override var prefersStatusBarHidden: Bool {
return true
}
In both my UIWindow's rootViewController and the main ViewController. This hides the status bar, but it also hides my UIWindow. My UIWindow's windowLevel is UIWindowLevelStatusBar + 1, but I tested other windowLevels and it was hidden regardless of the level.
Setting an opaque background for my custom UIWindow is not an option.
How can I hide the status bar but not my custom UIWindow?
Edit: better solution
The same still holds true as before/below, but the actual code is shorter, simpler, and more Swifty.
In your AppDelegate, have
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
myStatusBarWindow.isHidden = false
return true
}
And, of course, hide the system status bar. Either do this in the build settings or info.plist, or in your view controller, say
override var prefersStatusBarHidden: Bool {
return true
}
Much better :)
Old solution
Unfortunately, I cannot find what is probably the best answer, but I have a workaround:
First show your window. Only after that should you hide the status bar. I am not sure why this works, but it does. You can do that like this:
// Class var
var statusBarHidden = false
// For example in viewDidLoad but only the order matters
override func viewDidLoad() {
myWindow.isHidden = false
statusBarHidden = true
setNeedsStatusBarAppearanceUpdate()
}
override var prefersStatusBarHidden: Bool {
return statusBarHidden
}
Through my experimentation I discovered that prefersStatusBarHidden is checked before viewDidLoad. Thus, we need to tell the view controller to check again once the window is shown. Again, I don't know why this works, but it does. If anyone can explain this phenomenon (why this order matters), that would be an excellent supplement to this solution.
My status bar is black and I'm trying to set as white, so I did what I found in some questions here and put this on my AppDelegate...
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
//Status bar color
UIApplication.shared.statusBarStyle = .lightContent
return true
}
There is no error in my console, nothing about this. The status bar text is still black. What could be causing this? There is another way to do that in swift 3.0?
ensure once in your project info.plist the row
View controller-based status bar appearance and set it to NO
In Swift3 you have to use following code, put anywhere in your view controller
override var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
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.
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
}
i wanna know if this can be done, i'm working on IOS 10, xCode 8 and swift 3, i tried various solutions from here but none works:
i tried to override the prefersStatusBarHidden, i tried to assign a false value but it's a get-only property and in appdelegate, i can't do this:
application.statusBarHidden = true
finally, i set in the plist the following:
Status bar is initially hidden to YES View
View controller-based status bar appearance to NO
and had no effect, i believe that all this solutions don't work because the upgrade to IOS 10.
Even after hiding the status bar for the entire app using:
application.isStatusBarHidden = true
AVPlayerViewController still showed the status bar. On going back to the presenting view controller (for which status bar was hidden earlier) status bar became visible. Tried to override prefersStatusBarHidden on both presenting and presented view controllers to no avail.
The only thing that worked was using deprecated method setStatusBarHidden in the presenting view controller's viewWillAppear method.
override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
UIApplication.shared.setStatusBarHidden(true, with: .none)
}
You can hide the status bar in any or all of your view controllers just by adding this code:
override var prefersStatusBarHidden: Bool {
return true
}
Any view controller containing that code will hide the status bar by default.
If you want to animate the status bar in or out, just call setNeedsStatusBarAppearanceUpdate() on your view controller – that will force prefersStatusBarHidden to be read again, at which point you can return a different value. If you want, your call to setNeedsStatusBarAppearanceUpdate() can actually be inside an animation block, which causes the status bar to hide or show in a smooth way.
from: https://www.hackingwithswift.com/example-code/uikit/how-to-hide-the-status-bar
This work for me:
override var prefersStatusBarHidden: Bool {
get {
return true;
}
}
Simply subclass the AVPlayerViewController:
class PlayerViewController: AVPlayerViewController {
override var prefersStatusBarHidden: Bool {
return true
}
}
and use PlayerViewController()
This can be solved using extension of AVPlayerViewController:
Add the following line to AVPlayerViewController
extension AVPlayerViewController{
override open var prefersStatusBarHidden: Bool {
return true
}
}
Do this steps:
In info.plist file set
View controller-based status bar appearance = NO
in AppDelegate.swift file
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// use this code to hide status bar
application.isStatusBarHidden = true
return true
}
This codes enough to hide status bar in swift 3.
