UIApplication.sharedApplication().setStatusBarStyle() deprecated in iOS 9

Question

I have been using

UIApplication.sharedApplication().setStatusBarStyle()

In my appDelegate and it has worked fine, but since iOS 9, this method

Answer 1

This worked fine for me in Xcode 7.

In AppDelegate:

UIApplication.sharedApplication().statusBarStyle = .LightContent

Answer 2

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 3

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 4

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 5

Swift 5, iOS 13.5+

I'm gonna make a recap that I hope it's gonna be helpful.

#1: General solution without using preferredStatusBarStyle

To answer the question, if we don't want to care about exceptions screens and not use the preferredStatusBarStyle property from view controllers as Apple recommends, I think that indeed setting the UIViewControllerBasedStatusBarAppearance to false and changing the Status Bar Style under General settings -> Deployment info to light, as @Rick already recommended, is the way to go.

#2: Using preferredStatusBarStyle

For my case, I wanted to be able to have the UIStatusBarStyle.lightContent as default, but with some screens having the UIStatusBarStyle.default; and in these kind of cases, the solution #1 isn't possible.

Since also having a general extension to UIViewController that allows to change the default value isn't obviously possible for this property, the only and best way to proceed in these cases if we don't want to use deprecated methods, is via inheritance.

So, a possibility is to have a general BaseViewController (and also the BaseNavigationController if you use one) that you controller inherits from, that sets the preferredStatusBarStyle to .lightContent.

With this approach, now you can simply set the style to default where needed, while maintaining the lightContent as default.

Answer 6

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:
