UIStatusBar style change + Xcode 10 + iOS 12

This article will help you to change the UIStatusBar style using Xcode 10 or later. Earlier we use, App.app().statusBarStyle = .default to change the appearance of UIStatusBar. From iOS 9.0 this is deprecated.

Now let us check how to change the UIStatusBar style.

Step 1:

Create a single view app, add one parameter “View controller-based status bar appearance” in Info.plist and set it to “NO”.

Step 2:

We have to override “preferredStatusBarStyle” and call “setNeedsStatusBarAppearanceUpdate” in order to change our status bar style.

eg: override var preferredStatusBarStyle: UIStatusBarStyle { return .default }

setNeedsStatusBarAppearanceUpdate()

Let’s try to change the color of the status bar with 2 button actions.

Define a var in our ViewController

var isDefault: Bool = false

Add 2 buttons named Black and White in your View Controller on in Storyboard and create corresponding IBActions for those.

@IBAction func black(_ sender: Any) {

isDefault = true

setNeedsStatusBarAppearanceUpdate()

}

@IBAction func white(_ sender: Any) {

isDefault = false

setNeedsStatusBarAppearanceUpdate()

}

That is it. Now the app will change status bar color with button actions.
