UISearchBar delegate not responding to cancel button

Question

I have a UIViewController that is a UISearchBarDelegate and a MKMapViewDelegate. The searchBarSearchButtonClicked event works fine, but when testing in iOS 4.2 the searchBarCancelButtonClicked never gets called when hitting the cancel button. In 4.3 everything works fine. I have other views with identical code and it works fine. I have triple checked the method signatures.

Could it be something to do with the MapView, or am I doing something blatantly wrong?

My .h file:

@interface MyViewController : UIViewController <UISearchBarDelegate,MKMapViewDelegate,UIAlertViewDelegate>{
MKMapView *mapMainView;
UISearchBar *sBar;

}

@property (nonatomic, retain) UISearchBar *sBar;
@end

And I create the search bar like so:

sBar = [[[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 320.0, 70.0)] autorelease];
sBar.delegate = self;
sBar.showsCancelButton = YES;
[self.view addSubview:sBar];
[sBar becomeFirstResponder];

The method:

- (void)searchBarCancelButtonClicked:(UISearchBar *)searchBar
{
[searchBar resignFirstResponder];
searchBar.hidden = YES;
}

Does anyone have an idea of why this may be happening?

Answer 1

I had the exact same problem. Holding the cancel button for a few seconds worked.

The reason for me was that I had implemented UITapGestureRecognizer in the tableview. So this took precedence over the button click or 'x' button click in the search bar.

The solution in my case was to restrict the gesture recognition to only the backgroundview of the tableview. I guess similar thing might be happening in your case. Try to restrict the gesture recognizers to the minimum subview required and the search bar should be outside that view.
