I want white status bar in my app. For this I set View controller-based status bar appearance to NO and Status bar style to UIStatusBarStyleLightContent. But now I need to hide status bar in some view controllers. To hide it I have to set View controller-based status bar appearance to YES and add - (BOOL)prefersStatusBarHidden {return YES;}. But status bar is black now. It's black when View controller-based status bar appearance is YES and white if NO. So the question is, how to set white status bar and hide it?
UPD:
code in VC that I want to have white status bar (prefferdSTatusBarStyle not called)
code in VC with hidden status bar
.plist settings
Result is black status bar, that hides in some VC
UPD2:
I know it's bad to use deprecated methods but with [[UIApplication sharedApplication] setStatusBarHidden:YES]; everything works as I want. If anyone have better solution please let me know.
This is the swift version:
To hide the status bar or change it's appearance, you need to override the following properties in your view controller itself
override var prefersStatusBarHidden: Bool{
return true
}
the above hides the status bar and below if you want to set it to white:
override var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
In your plist file add View controller-based status bar appearance Bool property and set it to YES.
Now in your view controller add the methods like below:
// TO MAKE STATUS BAR WHITE
override func preferredStatusBarStyle() -> UIStatusBarStyle {
return .LightContent
}
// TO MAKE STATUS BAR BLACK
override func preferredStatusBarStyle() -> UIStatusBarStyle {
return .LightContent
}
// RETURN TRUE TO HIDE AND FALSE TO SHOW STATUS BAR
override func prefersStatusBarHidden() -> Bool {
return true
}
For Objective-C
- (BOOL)prefersStatusBarHidden {
return NO;
}
-(UIStatusBarStyle)preferredStatusBarStyle {
return UIStatusBarStyleLightContent;
}
For removing redundant code you can make a BaseViewController as subclass of UIViewController and add the methods in that class. And override the method in the class which requires change.
you can set using xcode status bar style is "light"
if your viewcontroller is embedded in UInavigationController then try writing this code in your
-(BOOL)prefreStatusBarHidden
{
return [self.navigationController prefersStatusBarHidden];
}
You can do this by setting the navigation background image in your base viewcontroller.
UIImage *bgImage = [UIImage imageNamed:#"bg_navigationbar"];
[self.navigationController.navigationBar setBackgroundImage:bgImage forBarMetrics:UIBarMetricsDefault];

I am able to hide the status bar on the launch screen by setting Status bar is initially hidden to YES in Info.plist and then I want to show it on my first view controller with a .lightContent style.
However UIApplication.shared.statusBarStyle = .lightContent is deprecated since iOS 9 (so I don't want to use it) and using the following code give me a black status bar on my first view controller.
override var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
How can I change the status bar style when my first view controller load?
I am trying to find a global solution like UIApplication.shared.statusBarStyle = .lightContent since I don't really want to set the status bar style for every view controller.
I have tested the solutions with View controller-based status bar appearance set to YES and NO.
The problem you're experiencing is that UINavigationController doesn't defer the choice of status bar to its view controllers.
Instead, for a navigation controller, the status bar style can be set by adjusting the barStyle property of its navigationBar.
If it is set to a black style, then the status bar will be light style:
navigationController?.navigationBar.barStyle = .black
Note, that this will also change the color of the navigationBar, however you can still set the bar's colour to whatever you want using barTintColor:
navigationController?.navigationBar.barTintColor = .purple
If you want to make a global change, so that all instances of UINavigationController use the same status bar style (useful if you've got multiple tabs all of which use a navigation controller), then you can add an extension on UINavigationController and override the preferredStatusBarStyle property:
extension UINavigationController {
open override var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
}
A final option, is to defer the choice to the view controllers in the navigation controller's stack.
To do that, override the childViewControllerForStatusBarStyle property of your navigation controller extension and have it return the topViewController:
extension UINavigationController {
open override var childViewControllerForStatusBarStyle: UIViewController? {
return topViewController
}
}
In this case, you'll need to override preferredStatusBarStyle in all of your view controllers (not the optimal approach, but it's an option if you need this granular level of control on a per-child-controller basis).
All of these solutions require that your View controller-based status bar appearance key in Info.plist is set to YES.
I try to put my Status Bar in Light Content.
The problem is that I have set View controller-based status bar
appearance to YES .
In my ViewController I put :
override open var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
I also try to put this in my AppDelegate :
application.statusBarStyle = .lightContent
After thats I still have a Dark (black) Status Bar.
ios 10 and swift 3
Change in info.plist the row View controller-based status bar appearance and set it to NO
Change in appDelegate.swift in didFinishLaunchingWithOptions
UIApplication.shared.statusBarStyle = .lightContent
In perticular viewcontroller use
override var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
In your ViewController's viewDidLoad method try calling
self.setNeedsStatusBarAppearanceUpdate()
didFinishLaunching Method in AppDelegate Class Single line code.
application.statusBarStyle = .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
}
Set value of .plist according to status bar style setup level.
I have a UITabBarController as the root view controller. Each tab has a view controller embedded inside of a navigation controller. My navigation bars are a dark color so I need the status bar to be set to .lightContent. I also need to hide the status bar dynamically.
If I set "View controller-based status bar appearance" to "NO", I can set the status bar correctly to ".lightContent", but I cannot hide the status bar dynamically.
If I set "View controller-based status bar appearance" to "YES", the status bar will only set to ".lightContent" if a navigation bar is NOT present.
This is what I use in each view controller to show or hide the status bar:
var shouldHideStatusBar: Bool = false {
didSet { self.setNeedsStatusBarAppearanceUpdate() }
}
override var prefersStatusBarHidden: Bool { return shouldHideStatusBar }
override var preferredStatusBarUpdateAnimation: UIStatusBarAnimation { return .slide }
override var preferredStatusBarStyle: UIStatusBarStyle { return .lightContent }
I have also tried:
navigationController?.navigationBar.barStyle = .black
There must be something I am missing in order to set the status bar to .lightContent and still be able to dynamically show and hide the status bar.
Resulted to using a deprecated method:
UIApplication.shared.setStatusBarHidden(true, with: .slide)
Not ideal, but works. Hopefully, someone has a solution without relying on a deprecated method.
You have to bubble these values up through your view hierarchy. For instance, your tabBarController should be asking its selectedViewController what its value for prefersStatusBarHidden is then your navigationController needs to ask its topViewController what its value for prefersStatusBarHidden is. This way when prefersStatusBarHidden is called on the tabBarController it relays back what the top most view controller wants to do with the status bar.
I need a white status bar for my main initial ViewController, but also be able to hide it in another ViewController. I can do one or the other, but not both at the same time. Any suggestions?
I set it to white by setting
View controller-based status bar appearance key to NO in the
Info.plist
override func preferredStatusBarStyle() -> UIStatusBarStyle {
return .LightContent
}
And to hide it (on another ViewController presented modally) I do,
override func prefersStatusBarHidden() -> Bool {
return statusBarHidden
}
however it won't hide unless I remove the key I previously added to the Info.plist, but if I remove the key, then the status bar goes back to black.
EDIT-MY Solution:
The View controller classes were not working in my case because I have the main view controller embedded in a navigation controller, my fix was to override the same methods but for the navigation controller instead of the view controller in question.
extension UINavigationController {
public override func preferredStatusBarStyle() -> UIStatusBarStyle {
return .LightContent
}
}
If you add
View controller-based status bar appearance key to NO in the Info.plist
You should use [UIApplication setStatusBarHidden:withAnimation:] and [UIApplication setStatusBarStyle:animated:] to change to the statusbar's appearance. Your method won't be called
As it is said in apple's document:
UIViewControllerBasedStatusBarAppearance (Boolean - iOS) Specifies whether the status bar appearance is based on the style preferred by the view controller that is currently under the status bar. When this key is not present or its value is set to YES, the view controller determines the status bar style. When the key is set to NO, view controllers (or the app) must each set the status bar style explicitly using the UIApplication object.
UIViewControllerBasedStatusBarAppearance key is the same as View controller-based status bar appearance key.
If you don't add the key,your method should work. try add both methods in these two Viewcontrollers, and add some breakpoint to see they're called or override by mistake.
The code in Swift 3.0 Xcode 8.2 works for me:
override open var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
override open var prefersStatusBarHidden: Bool {
return true
}
i am trying to change the status Bar Style of UISplitViewController
i used to do that with UINavigationBar
UINavigationBar.appearance().barStyle = UIBarStyle.Black
but the UISplitViewController does not have an appearance property
is there anyway to change that Style ?
View controller-based status bar appearance is set to YES by default. So you just have to subclass your split controller like
class SplitViewController: UISplitViewController {
override func preferredStatusBarStyle() -> UIStatusBarStyle {
return UIStatusBarStyle.BlackOpaque
}
}
