SetStatusBarHidden deprecated in iOS 9.0

Question

I upgrade my code from iOS 8 to iOS 9. I have a piece of code in my program [[UIApplication applicationName] setStatusBarHidden:YES]; .

I get a warning: setStatusBarHidden is deprecated in iOS 9.0, Use is [UIViewController prefersStatusBarHidden ". If I just replaced" setStatusBarHidden "with" prefersStatusBarHidden ", I get an" instance method not found ". Can someone please suggest me how to solve this problem?

Answer 1

Add the code below to your view controller.

  - (BOOL)prefersStatusBarHidden { return NO; } 

Note:

• If you change the return value for this method, call setNeedsStatusBarAppearanceUpdate .
• For childViewController, to indicate that the child view controller should control privileged status, hidden / unclosed state, implement childViewControllerForStatusBarHidden .

Answer 2

you need to add a method to your viewController.m

 - (BOOL)prefersStatusBarHidden { return NO; } 

Answer 3

Swift 3.1 Xcode 8.2.1

• Change the info.plist line. Look at the controller-based status bar and set it to NO.

• In your target settings, check "Hide status bar"

Both steps required

Answer 4

Swift 3 with Xcode 8.3.3

1) Add a line to Info.plist.

2) In your ViewController ViewDidLoad (), override add:

  UIApplication.shared.isStatusBarHidden = true 

Answer 5

Here is my quick code for setting the status bar and style.

 extension UIViewController { public var privateStatusBarHidden: Bool { return statusBarHidden } public var privateStatusBarStyle: UIStatusBarStyle { return statusBarStyle } public func setStatusBarHidden(hidden: Bool, animated: Bool = false) { statusBarHidden = hidden if animated { UIView.animate(withDuration: 0.25, animations: { self.setNeedsStatusBarAppearanceUpdate() }) } else { self.setNeedsStatusBarAppearanceUpdate() } } public func setStatusBar(style: UIStatusBarStyle) { statusBarStyle = style self.setNeedsStatusBarAppearanceUpdate() } public static func swizzleStatusBarHiddenPropertyForViewController() { var original = class_getInstanceMethod(UIViewController.self, #selector(getter: UIViewController.prefersStatusBarHidden)) var changeling = class_getInstanceMethod(UIViewController.self, #selector(getter: UIViewController.privateStatusBarHidden)) method_exchangeImplementations(original, changeling) original = class_getInstanceMethod(UIViewController.self, #selector(getter: UIViewController.preferredStatusBarStyle)) changeling = class_getInstanceMethod(UIViewController.self, #selector(getter: UIViewController.privateStatusBarStyle)) method_exchangeImplementations(original, changeling) original = class_getClassMethod(UIViewController.self, #selector(UIViewController.swizzleStatusBarHiddenPropertyForViewController)) changeling = class_getClassMethod(UIViewController.self, #selector(UIViewController.emptyFunction)) method_exchangeImplementations(original, changeling) } @objc private static func emptyFunction() {} } 

Using

• in laucing function

UIViewController.swizzleStatusBarHiddenPropertyForViewController ()

• for hide / show statusBar, in a UIViewController

. self.setStatusBar (hidden: true / false)

Answer 6

prefersStatusBarHidden is available from iOS 7+ .

Use this in your UIViewController class

  var isHidden = true{ didSet{ self.setNeedsStatusBarAppearanceUpdate() } } override var prefersStatusBarHidden: Bool { return isHidden } 

If you change the return value for this method, call setNeedsStatusBarAppearanceUpdate (). To indicate that the child, the view manager should monitor the preferred status bar, hidden / unclosed, implements the childViewControllerForStatusBarHidden method.

Answer 7

The prefersStatusBarHidden solution does not work.

Which worked instead of [[UIApplication applicationName] setStatusBarHidden: YES];

use

UIApplication.sharedApplication.statusBarHidden = YES;
