Dismissing keyboard from UISearchBar when the X button is tapped

Question

I\'m using the UISearchBar (but not the SearchDisplayController that\'s typically used in conjunction) and I\'d like to dismiss the keyboard when you hit the \'X\' button.

Answer 1

I used a combination of @radiospiel's answer and also the answer that @Tozar linked to:

@interface SearchViewController : UIViewController  {
    // all of our ivar declarations go here...
    BOOL shouldBeginEditing;
    ....
}

...
@end

@implementation SearchViewController
...
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
    if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) {
        ...
        shouldBeginEditing = YES;
    }
}
...

- (void) searchBar:(UISearchBar *)theSearchBar textDidChange:(NSString *)searchText {
    // TODO - dynamically update the search results here, if we choose to do that.

    if (![searchBar isFirstResponder]) {
        // The user clicked the [X] button while the keyboard was hidden
        shouldBeginEditing = NO;
    }
    else if ([searchText length] == 0) {
        // The user clicked the [X] button or otherwise cleared the text.
        [theSearchBar performSelector: @selector(resignFirstResponder)
                        withObject: nil
                        afterDelay: 0.1];
    }
}

- (BOOL)searchBarShouldBeginEditing:(UISearchBar *)bar {
    // reset the shouldBeginEditing BOOL ivar to YES, but first take its value and use it to return it from the method call
    BOOL boolToReturn = shouldBeginEditing;
    shouldBeginEditing = YES;
    return boolToReturn;
}
@end
