UISearchBar in navigationbar
To put searchBar into the center of navigationBar:
self.navigationItem.titleView = self.searchBarTop;
To put searchBar to the left/right side of navigationBar:
UIBarButtonItem *searchBarItem = [[UIBarButtonItem alloc] initWithCustomView:searchBar];
self.navigationItem.rightBarButtonItem = searchBarItem;
As of iOS 7, the UISearchDisplayController supports this by default. Set the UISearchDisplayController's displaysSearchBarInNavigationBar = YES
to get this working easily.
Per the documentation:
Starting in iOS 7.0, you can use a search display controller with a navigation bar (an instance of the UINavigationBar class) by configuring the search display controller’s displaysSearchBarInNavigationBar and navigationItem properties.
As one commenter noted, using searchDisplayController.displaysSearchBarInNavigationBar = true
ends up hiding any existing left/right bar button items.
I've found two different ways of adding a searchBar
to a navigationBar
using iOS7's new property on searchDisplayController
.
1) Nib Based Approach
If you're using a .xib, you can set a User Defined Runtime Attribute for this value and for whatever reason, the leftBarButtonItem stays in tact. I have not tested it with a rightBarButtonItem.
2) Code (Timing Matters)
If you want to implement in code, timing seems to matter. It seems that you must add the searchBar
to the navigationBar
first, then set your barButtonItem
.
- (void)viewDidLoad
{
...
self.searchDisplayController.displaysSearchBarInNavigationBar = true;
self.navigationItem.leftBarButtonItem = [UIBarButtonItem new];
...
}
