swift 隐藏狀态欄_隐藏狀态欄swift 4

I am trying to hide status bar in one of my UIViewControllers (Swift 4).

Firstly, I set View controller-based status bar appearance to YES in Info.plist.

I overrode the prefersStatusBarHidden property in my controller:

override var prefersStatusBarHidden: Bool {

return true

}

And in viewDidLoad(), I added setNeedsStatusBarAppearanceUpdate() function to force the prefersStatusBarHidden property to be read.

After all that, I still see the status bar on that UIViewController.

Can someone help me, please?

You probably found your own solution to this already, but I got it working this way:

override func viewWillAppear(_ animated: Bool) {

// Sets the status bar to hidden when the view has finished appearing

let statusBar: UIView = UIApplication.shared.value(forKey: "statusBar") as! UIView

statusBar.isHidden = true

}

override func viewWillDisappear(_ animated: Bool) {

// Sets the status bar to visible when the view is about to disappear

let statusBar: UIView = UIApplication.shared.value(forKey: "statusBar") as! UIView

statusBar.isHidden = false

}
