Iphone – How to enable cancel button with UISearchBar

cancel-buttoniphoneuisearchbar

In the contacts app on the iPhone if you enter a search term, then tap the "Search" button, the keyboard is hidden, BUT the cancel button is still enabled. In my app the cancel button gets disabled when I call resignFirstResponder.

Anyone know how to hide the keyboard while maintaining the cancel button in an enabled state?

I use the following code:

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

The keyboard slides out of view, but the "Cancel" button to the right of the search text field is disabled, so that I cannot cancel the search. The contacts app maintains the cancel button in an enabled state.

I think maybe one solution is to dive into the searchBar object and call resignFirstResponder on the actual text field, rather than the search bar itself.

Any input appreciated.

This method worked in iOS7.

- (void)enableCancelButton:(UISearchBar *)searchBar
{
    for (UIView *view in searchBar.subviews)
    {
        for (id subview in view.subviews)
        {
            if ( [subview isKindOfClass:[UIButton class]] )
            {
                [subview setEnabled:YES];
                NSLog(@"enableCancelButton");
                return;
            }
        }
    }
}

(Also be sure to call it anywhere after [_searchBar resignFirstResponder] is used.)

Iphone – UISearchbar clearButton forces the keyboard to appear

This is an old question and I just came across the same issue and managed to solve it the following way:

When the searchBar:textDidChange: method of the UISearchBarDelegate gets called because of the user tapping the 'clear' button, the searchBar hasn't become the first responder yet, so we can take advantage of that in order to detect when the user in fact intended to clear the search and not bring focus to the searchBar and/or do something else.

To keep track of that, we need to declare a BOOL ivar in our viewController that is also the searchBar delegate (let's call it shouldBeginEditing) and set it with an initial value of YES (supposing our viewController class is called SearchViewController):

@interface SearchViewController : UIViewController <UISearchBarDelegate> {
    // 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;
    }
}
...
@end

Later on, in the UISearchBarDelegate, we implement the searchBar:textDidChange: and searchBarShouldBeginEditing: methods:

- (void)searchBar:(UISearchBar *)bar textDidChange:(NSString *)searchText {
    NSLog(@"searchBar:textDidChange: isFirstResponder: %i", [self.searchBar isFirstResponder]);
    if(![searchBar isFirstResponder]) {
        // user tapped the 'clear' button
        shouldBeginEditing = NO;
        // do whatever I want to happen when the user clears the search...
    }
}


- (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;
}

Basically, that's it.

Objective-c – Cocoa Touch – UISearchBar Keyboard – Hide ‘Search’ Button

SOLVED. I just used a textfield instead upon the searchbar so it looks similar.
