关于点击uisearchbar后给屏幕增加手势的问题

原来只需要在这个delegate里增加个手势就行了啊，记得需要在下面的delegate里remove掉 (因为手势弄成全局的了，所以还需要在dealloc里release）

#pragma mark--

#pragma mark-UISearchBarDelegate

- (void)searchBarTextDidBeginEditing:(UISearchBar *)searchBar

{

    if(!_resignGes){

        _resignGes = [[UITapGestureRecognizer alloc] init];

    }

    _resignGes.numberOfTapsRequired = 1;

    [_resignGes addTarget:self action:@selector(searchResignFirstResponder)];

    [self.view addGestureRecognizer:_resignGes];

。。。。

}

-(void)searchBarCancelButtonClicked:(UISearchBar *)searchBar

{

    [_searchBar resignFirstResponder];

    if(!_searchBar.isFirstResponder){

        [self.view removeGestureRecognizer:_resignGes];

    }

    _searchBar.showsCancelButton = NO;

}
