UISearchController changing status bar color on invocation

Question

I have the following code in my app, specifically in viewDidLoad: that sets up my UISearchController.

self.searchController = [[UISearchController alloc] initWithSearchResultsController:nil];
self.searchController.searchResultsUpdater = self;
self.searchController.hidesNavigationBarDuringPresentation = NO;
self.searchController.dimsBackgroundDuringPresentation = NO;
self.definesPresentationContext = NO;
self.searchController.searchBar.scopeButtonTitles = @[];
self.searchController.searchBar.searchBarStyle = UISearchBarStyleProminent;

[_tableView setTableHeaderView:_searchController.searchBar];

Whenever the search bar (which is added to the tableView) is invoked, the UIStatusBar color changes from UIStatusBarStyleLightContent to dark (white to black). Now, I figured out if I set,

self.definesPresentationContext = NO;

to the following:

self.definesPresentationContext = YES;

the issue is solved and the UIStatusBar color is preserved. However, another issue arises. When self.definesPresentationContext is set to YES , upon invocation the search bar shifts down for some reason, coincidently (or rightfully so) right under where the bottom of the UIRefreshControl displays on the tableView.

It does not work if i set hidesNavigationBarDuringPresentation to YES, bar is changing to black (from white) no matter I do. — Jakub Truhlář, May 06 '16 at 08:36

Setting View-controller based status bar appearance to No is not a solution if you want the view controllers to define how the status bar looks.

My solution consisted of two things:

Make sure the presenting view controller has definesPresentationContext set to YES
Make sure both the view controller that is pushed and the pushing view controller are laid out beneath the navigation bar (set extendedLayoutIncludesOpaqueBars to YES)

Interesting fix. Curious, did you have an issue with the search bar shifting down when invoked if extendedLayoutIncludesOpaqueBars was set to NO but definesPresentationContext set to YES? – Aug 12 '15 at 00:30
Yep. Exactly the same you described. – pfandrade Aug 12 '15 at 14:24

As of iOS 10 (maybe earlier?), if you have "View controller-based status bar appearance" set to YES in your Info.plist, simply set the preferredStatusBarStyle in the UIViewController that the UISearchController is included in.

- (UIStatusBarStyle)preferredStatusBarStyle {
    return UIStatusBarStyleLightContent;
}

(you don't need to subclass or create a category/extension of UISearchController to override preferredStatusBarStyle... it uses the preferredStatusBarStyle that you set in your UIViewController)

This is the right answer, putting it in the `UISearchController` subclass doesn't work. Thank you! — Markus, Sep 28 '18 at 20:22

I needed full control over my status bar colour. I use the extensions found here to ensure that the visible view controller is setting the preferred status bar colour.

For me it was therefore necessary to override UISearchController and override preferredStatusBarStyle and return the style I wanted.

This worked fine until iOS 10, did you find any better solution for 10? – gklka Sep 09 '16 at 09:17

I found the solution: since iOS 10, `UISearchController` asks the presenting view controller (usually your table view controller) for status bar style. You should implement `-preferredStatusBarStyle` there. – gklka Oct 28 '16 at 11:42

If you ViewController is inside a TabBarController then -

Instead of self.definesPresentationContext = YES;

Use self.tabBarController.definesPresentationContext = YES;

This worked for me in above scenario.

The status bar that is displayed when the search controller is presented (is active) belongs to the search controller. To set the preferred status bar style you must add a category to UISearchController and then override the preferredStatusBarStyle method.

Below is an example of the implementation file of the category:

@implementation UISearchController (Customization)

-(UIStatusBarStyle)preferredStatusBarStyle {
    return UIStatusBarStyleLightContent;
}

@end

Or we can write an extension on Swift (version 2, but you can translate it to 3 easily):

extension UISearchController {

   override public func preferredStatusBarStyle() -> UIStatusBarStyle{
      if Theme.lightTheme() {
          return UIStatusBarStyle.Default
      }
      else {
          return UIStatusBarStyle.LightContent
      }
   }
}

Where Theme is a class that regulate app colour theme.
