Hide the keybord on clicking enter button or search button

I've added the UISearchBar button inside the UIBarButtonItem inside the toolbar button.

In the below form:

// search bar
UISearchBar *searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 260, 44)];
UIBarButtonItem *searchBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:searchBar];
[search开发者_如何转开发Bar release];

[buttons addObject:searchBarButtonItem];

Now the problem in when I click on the UISearchBar keyboard appears. I'd like to hide the keyboard on clicking in enter or search button. How can i do this?

Implement a method from UISearchBarDelegate:

- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar {
    [searchBar resignFirstResponder];
}

For Swift

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

You need to process the UISearchBarDelegate protocol methods.

In the following methods, call -resignFirstResponder method of UISearchBar.

- (BOOL)searchBarShouldBeginEditing:(UISearchBar *)searchBar
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
- (BOOL)searchBarShouldEndEditing:(UISearchBar *)searchBar

The detail of above delegate methods can be found in the Apple official document. I often resign first responder inside those delegate methods as the end of searching.

you can use UISEarchBar's delegate method

- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
{
   [searchBar resignFirstResponder];
}

and for enter (not tested)

- (void)searchBar:(UISearchBar *)searchBar textDidChange:(NSString *)searchText;   // called when text changes (including clear)
{
    if ([searchText isEqualToString:@"\n"])
               [searchBar resignFirstResponder];
}

Hope this helps you...

In the header file, add or connect to the UISearchBar outlet: should look something like this:

@property (weak, nonatomic) IBOutlet UISearchBar *searchBarName;

Then, in the implementor, add the following:

self.searchBarName.delegate = self;

in the viewDidLoad function.

Then add the following function:

- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar
{
    [self.searchBarName resignFirstResponder];
}

Also as mentioned above ensure that this is added/extended in the header
UISearchBarDelegate

use [textField endEditing:YES];, it should work for you, or you can create an oject of ur button and do [self.buttonObj resignFirstResponder]
