UIApplication.sharedApplication().setStatusBarStyl

Question

I have been using

UIApplication.sharedApplication().setStatusBarStyle()

In my appDelegate and it has worked fine, but since iOS 9, this method is deprecated and I can't find an alternative.

I want to change the statusbar style to .LightContent for my whole application, but the only suggestion xCode gives me is to handle this in every VC separately with;

override func preferredStatusBarStyle() -> UIStatusBarStyle {
    return .LightContent
}

Has anyone an idea how to do this for the whole application?

Thanks in advance

Answer 1

In Swift 3 is like that:

 UIApplication.shared.statusBarStyle = .lightContent

Answer 2

for those still working with Swift 3 in Xcode 8:

( slightly different to Marlon Ruiz's answer above, not an override function, but within viewDidLoad )

override func viewDidLoad() {
    super.viewDidLoad()

    var preferredStatusBarStyle: UIStatusBarStyle {
        return .lightContent
    }
}

Answer 3

To dynamically update UIStatusBarStyle on view controllers use this method

this will also remove deprecated warning

'setStatusBarStyle:' is deprecated: first deprecated in iOS 9.0 - Use -[UIViewController preferredStatusBarStyle]

for calling

[[UIApplication sharedApplication] setStatusBarStyle:style];

Let's Get Started

Objective - C

define UtilityFunction

+(void)setStatusBarStyle:(UIStatusBarStyle )style {    
    [[NSUserDefaults standardUserDefaults] setInteger:style forKey:@"UIStatusBarStyle"];
    [[NSUserDefaults standardUserDefaults] synchronize];
}

over-ride this method in your BaseViewController

- (UIStatusBarStyle)preferredStatusBarStyle {
    UIStatusBarStyle style = [[NSUserDefaults standardUserDefaults] integerForKey:@"UIStatusBarStyle"];
    return style;
}

set UIStatusBarStyle value for the AnyViewController using a UtilityFunction like below:

[UtilityFunctions setStatusBarStyle:UIStatusBarStyleDefault];

// call below code for preferred style
[self preferredStatusBarStyle];

Swift 4.0

define UtilityFunction

class func setPreferedStyle(style:UIStatusBarStyle)->Void {
    UserDefaults.standard.set(style, forKey: "UIStatusBarStyle")
    UserDefaults.standard.synchronize()
}

over-ride this method in your BaseViewController

override var preferredStatusBarStyle: UIStatusBarStyle {
    if let style: UIStatusBarStyle = UIStatusBarStyle(rawValue:UserDefaults.standard.integer(forKey: "UIStatusBarStyle")) {
        return style
    }
    return UIStatusBarStyle.lightContent
}

set UIStatusBarStyle value for the AnyViewController using a UtilityFunction like below:

Utility.setPreferedStyle(style: .lightContent)

// call below code for preferred style
preferredStatusBarStyle()

Answer 4

In info.plist, set: View controller-based status bar appearance boolean to NO

In app delegate's didFinishLaunchingWithOptions, use function parameter application (and not the [UIApplication sharedApplication] or simillary the UIApplication.sharedApplication() in swift) to set this like so:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    application.statusBarStyle = UIStatusBarStyleLightContent;
}

Answer 5

In swift 3.

In your view controller:

override var preferredStatusBarStyle: UIStatusBarStyle {
    return UIStatusBarStyle.lightContent
}

If you wish when the app run your launch screen also has the status bar in lightContent then:

Answer 6

This worked fine for me in Xcode 7.

In AppDelegate:

UIApplication.sharedApplication().statusBarStyle = .LightContent
