Put status Bar Color in LightContent - ios

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.

Color of status bar on Xcode 9.3 not changing despite overriding

I've used the following code:
override var preferredStatusBarStyle: UIStatusBarStyle {
return .lightContent
}
It does work on my initial view controller scene, but it does not work on any other ones.
I've put the same function on each viewcontroller's Swift file.
Thanks in advance.
You can change the info.plist the row View controller-based status bar appearance and set it to NO
Then put this line of code in your appDelegate.swift in didFinishLaunchingWithOptions
UIApplication.shared.statusBarStyle = .lightContent
When you override preferredStatusBarStyle in a viewcontroller then it will work for that controller. But if you want to change whole application status bar style then put this line of code in you AppDelegate class.
UIApplication.shared.statusBarStyle = .lightContent
Perform the below changes to keep the status bar of color white.
Set View controller-based status bar appearance in info.plist = No
In AppDelegate, set UIApplication.shared.statusBarStyle = .lightContent
1.Change in info.plist the row View controller-based status bar appearance and set it to NO
2.Change in appDelegate.swift in didFinishLaunchingWithOptions
UIApplication.shared.statusBarStyle = .lightContent

How do you change the colour of the status bar with a button?

I'm trying to implement a button that changes the background of my app from white to black along with the colour of the status bar. Right now I have
#IBAction func buttonTapped(_ sender: Any) {
self.view.backgroundColor = UIColor.black
UIApplication.shared.statusBarStyle = .lightContent
}
This doesn't seem to work. Does anyone know of a way of changing the colour of the status bar font without reloading the entire view?
If you want to set status bar style, application level then set UIViewControllerBasedStatusBarAppearance to NO in your .plist file.

Change status bar style with animation

Since UIApplication.shared.setStatusBarStyle(.default, animated: true) is deprecated from IOS9 is it possible to change status bar style with animation on push? I cannot find any description in docs.
It's now a variable you have to override:
override var preferredStatusBarStyle: UIStatusBarStyle
override var preferredStatusBarUpdateAnimation: UIStatusBarAnimation
Depending on when you update the status bar, you might also have to call setNeedsStatusBarAppearanceUpdate()
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.
To tackle the animation part the way I made it transition smoothly between .lightContent and .default was to use something similar to below each time you change it.
UIView.animate(withDuration: 0.2) {
self.setNeedsStatusBarAppearanceUpdate()
}
Place that in your VC you want the status bar to animate and you'll have a nice smooth animation.
override var preferredStatusBarStyle: UIStatusBarStyle {
return lightStatusBar ? .lightContent : .default
}
Above is a snippet of me changing the content based on a condition I have.

Status Bar Style - Swift 3 - change at any time

I'm finding it hard to change the status bar style programatically.
I see how to statically set it for each ViewController using a combo of (in ViewController.swift):
override var preferredStatusBarStyle: UIStatusBarStyle {
return UIStatusBarStyle.default
}
and (in info.plist):
View controller-based status bar appearance = YES
...
I'm looking to change it whenever I want!
Found the answer after quite a lot of digging!
Set (in info.plist):
View controller-based status bar appearance = NO
and remove the (in ViewController.swift):
override var preferredStatusBarStyle: UIStatusBarStyle {
return UIStatusBarStyle.default
}
...
Now you can use (in ViewController.swift):
UIApplication.shared.setStatusBarStyle(UIStatusBarStyle.lightContent, animated: true)
And, to initially set the style for each ViewController, use viewDidAppear:
override func viewDidAppear(_ animated: Bool) {
UIApplication.shared.setStatusBarStyle(UIStatusBarStyle.lightContent, animated: false)
}
swift 3
1.Change in info.plist the row View controller-based status bar appearance and set it to NO
2.Change in appDelegate.swift in didFinishLaunchingWithOptions
UIApplication.shared.statusBarStyle = .lightContent
Store the status bar style as a property in your view controller:
var statusBarStyle: UIStatusBarStyle = .default
And then implement preferredStatusBarStyle in the same view controller:
override var preferredStatusBarStyle: UIStatusBarStyle {
return statusBarStyle
}
Then when you change statusBarStyle make sure to also call setNeedsStatusBarAppearanceUpdate. The preferredStatusBarStyle method is automatically called when the view appears/disappears, but if you change the status bar style while your view is visible, you have to tell the view controller the status bar appearance needs updating.
Note you still need to make the changes to the plist, and if your view controller is in a navigation controller, you may need to handle the status bar changes there instead (via a UINavigationController subclass, for example).
UIApplication.shared.setStatusBarStyle(…) was deprecated in iOS 9.0, so don't use that.

Remove Translucency of UIStatusBar

I am trying to make my UIStatusBar not translucent at all.
While my UINavigationBar is completely white, I want the UIStatusBar to follow that behavior.
In my appDelegate - didFinishLaunchingWithOptions I was trying:
UIApplication.sharedApplication().statusBarStyle = .Default
But there is no way for me to set e.g. the alpha or translucency.
Any ideas?
1) In your info.plist file insert a new record with key "View controller-based status bar appearance" and set it to NO
2) In case the previous step does not work:
In your application(_:didFinishLaunchingWithOptions:) method of the AppDelegate.swift file put
UIApplication.sharedApplication().statusBarStyle = .LightContent // or .default
3) Try this inside your controller:
override var preferredStatusBarStyle: UIStatusBarStyle {
return .default
}
4) Put this in your viewDidLoad method:
self.setNeedsStatusBarAppearanceUpdate()
