The UISearchBar doesn't dismiss the keyboard when enter is pressed

Question

The UISearchBar doesn't dismiss the keyboard when enter is pressed, or the user touch somewhere else.

I need to use the remove keyboard button on the bottom right of the iOS keyboard in order to remove the keyboard and invoke:

- (void)searchBarTextDidEndEditing:(UISearchBar *)aSearchBar

How can I fix it?

Answer 1

- (void)searchBarTextDidEndEditing:(UISearchBar *)aSearchBar {
    [aSearchBar resignFirstResponder];
}

Also you have to set delegate for the UISearchBar: UISearchBarDelegate

It should work.

Here is sample code http://developer.apple.com/library/ios/#samplecode/ToolbarSearch/Listings/ToolbarSearch_APLToolbarSearchViewController_m.html#//apple_ref/doc/uid/DTS40009461-ToolbarSearch_APLToolbarSearchViewController_m-DontLinkElementID_9

Another option is searchBarSearchButtonClicked we can use.

- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
{
    [searchBar resignFirstResponder];
    // You can write search code Here
}

Answer 2

Add UISearchBarDelegate in .h

Also set SearchBar's object delegate to self.

you should do add UISearchBarDelegate's method:

- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
{
    [searchBar resignFirstResponder];
    // Do the search...
}

EDIT : Above doesnot work then add this:

[self.view endEditing:YES];

Answer 3

for swift 1.2 keyboard will hide when you click finished , and there is another function for cancel but it's not good to use it as when the user click cancel he might want to search for another word ...

func searchBarSearchButtonClicked(searchBar: UISearchBar) {
        searchBar.resignFirstResponder()
    }

Answer 4

Use the following code snippet to close/hide the keyboard when return button is clicked.

- (BOOL)searchBar:(UISearchBar *)searchBar shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text 
{

    if([text isEqualToString:@"\n"])
    {        
        [searchBar resignFirstResponder];
        return NO;
    }
        return YES;
}
