UISearchBar in place of UINavigationController UIN

Question

I have a UITableViewController with a UISearchDisplayController (and UISearchBar) that is contained in a UINavigationController as the root element. Is it possible to configure it so the UISearchBar appears in place of the UINavigationBar? I don't think hiding the navigation bar will work, a the next screen (pushed on) requires it to be visible (and this will create a strange animation glitch).

I'm basically going for a screen like the App Store search tab.

I've uploaded a sample screenshots of how it looks now:

Answer 1

In the viewDidLoad method of the controller you are pushing

[[self navigationController] setNavigationBarHidden:NO animated:YES];

Answer 2

Assign yourself as the delegate of the UINavigationController and implement - (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated.

Then use the passed in navigationController to hide the navigation bar. [navigationController setNavigationBarHidden:YES animated:animated]

Edit: Come to think of it, it would be better to pass the animated value into -setNavigationBarHidden:animated: as well. Code updated.

Here is my solution:
You don't need to hide the UINavigationBar, instead, you could merge the UISearchBar into UINavigationBar.

In YourClass.m file:
1. add a UISearchBar property
2. add the UISearchBar into the NavigationItem in the viewDidLoad section. code:

@interface YourClass ()
@property (weak, nonatomic) IBOutlet UISearchBar *searchBar;
@end

@implementation YourClass
- (void)viewDidLoad 
{
  [super viewDidLoad];

  // Reveal cancel button in UISearchBar.
  searchBar.showsCancelButton = YES;

  // Add UISearchBar as titleView of the UINavigationBar.
  self.navigationItem.titleView = searchBar;
}

last, don't forget to edit your .xib file. Just add the UISearchBar object right down the UINavigationBar and connect the referencing outlets of the UISearchBar to the File's Owner. Good luck!

I guess you can hide your navigationbar by setting the 'navigationBarHidden' property to true.

[navigationController setNavigationBarHidden:YES animated:NO];
