回答1:

Make sure the view controller which has the SearchBar implements the SearchBarDelegate and you set the searchBar.delegate to self:

@interface AddressSearchViewController : UIViewController <UISearchBarDelegate>

then implement the following method:

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

This will make the keyboard disappear when you tap the search button on the keyboard or the search bar

For the search bar:

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

And same thing for the text field:

- (void)textFieldDidEndEditing:(UITextField *)textField
{
    [textField resignFirstResponder];
}

Use this code in ViewDidLoad

-(void) ViewDidLoad
 {
    [super ........];
    UITapGestureRecognizer *gestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hideKeyboard)];
    [self.view addGestureRecognizer:gestureRecognizer];
    gestureRecognizer.cancelsTouchesInView = NO;    
 }

 - (void) hideKeyboard 
 {
    [texfieldname1 resignFirstResponder];
    [texfieldname2 resignFirstResponder];
 }
