How can I programmatically force a search in the UISearchBar?

How can I force the UISearchBar to automatically start a new search (like pressing the Search button)? Is there an easy way to achieve this?

Swift 5

If you just have a UISearchBar (not a UISearchViewController):

let searchBar: UISearchBar
searchBar.text = "foo" // Reset the search text
searchBar.becomeFirstResponder() // Select the field and bring up the keyboard

let searchBar: UISearchBar = /* The Searchbar */
searchBar.delegate?.searchBar?(searchBar, textDidChange: "")
searchBar.text = ""

This worked - Swift 4

   searchBar.text="Amber"
   self.searchBar(self.searchBar, textDidChange: "Amber")

I found that I needed to set the UISearchViewController to active before changing the value of the search field programatically to make UISearchViewController automatically perform the search:

// Need to set the searchDisplayController to active to 
// make the changes in search text trigger a search.
self.searchDisplayController.active = YES;
self.searchDisplayController.searchBar.text = @"New search string";

Swift 4

self.searchController.isActive = true
self.searchController.searchBar.text = "New search string"

After making sure that the text you want is inside your search bar you can call self.searchBarSearchButtonClicked(searchBar) (passing in your search bar) assuming you have already implemented this UISearchBarDelegate method searchBarSearchButtonClicked(_ searchBar: UISearchBar)

You can force your searchBar,

Objective C: 

[self searchBar:yourSearchBarName textDidChange: yourSearchingString];

Swift 3.0:

self.searchBar(self.yourSearchBarName, textDidChange: yourSearchingString)

This will trigger your searchBar.

seems dumb, but works, so it's not dumb ;)

NSString * forceReload = self.searchDisplayController.searchBar.text;
self.searchDisplayController.searchBar.text = forceReload;

Yes you only need to make an implicit call to the searchBarSearchButtonClicked: on your UISearchbarDelegate. Have a look to the official doc for more info about this delegate.

Just have the search input field become the first responder:

[self.searchInputField becomeFirstResponder];
