how do I properly change my status bar style in swift 2/ iOS 9?

Question

I'm attempting to change my status bar's style to .Light but the previous code I implemented in swift 1.2 seems not to work anymore.. here's the code:

override func viewDidLoad() {
        super.viewDidLoad()

        UIApplication.sharedApplication().statusBarStyle = .LightContent

    }

now I have my View controller-based status bar appearance info.plist setting to YES, and reading the UIKit doc, this will negate any statusBarStyle changes and keep it at default. However when I change the setting to 'NO' and change the statusBarStyle, I get this <Error>: CGContextSaveGState: invalid context 0x0. If you want to see the backtrace, please set CG_CONTEXT_SHOW_BACKTRACE environmental variable in my debugger.. So is this a bug in Xcode? because to change the status bar style you must change info.plist setting to NO, but when that happens.. error

Answer 1

Apple have added the capability to change the status bar style in the deployment info. Simply choose 'Light'.

Also set View controller-based status bar appearance key to NO in the Info.plist

Answer 2

I always did this way.

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    //Changing Status Bar
    override func preferredStatusBarStyle() -> UIStatusBarStyle {

        //LightContent
        return UIStatusBarStyle.LightContent

        //Default
        //return UIStatusBarStyle.Default
    }
}

It works in any swift 2.x version. This requires that you set View controller-based status bar appearance in your Info.plist file to YES.

Swift 3 just add View controller-based status bar appearance with value NO to info.plistand then add to ViewControllerwhere you want:

UIApplication.shared.statusBarStyle = UIStatusBarStyle.lightContent
