Dismissing Keyboard FirstResponder problems

So i am making an app and am having some problems with dismissing the keyboard from UISearchBar and UITextFields. Here is the structure of my app:

NavigationController -> ViewC1 - (Modally)-> ViewC2 -(Modally) -> ViewC3

I have a search box in ViewC1, and when the "Search" button on the keyboard is pressed the keyboard is dismissed, this works fine. However if i return to ViewC1 after being in ViewC3 the keyboard no longer dismisses when the "Search" button is pressed. In the search bar delegate method i have put as follows:

- (void) searchBarSearchButtonClicked:(UISearchBar *)search
{
if ([search isFirstResponder]) {
    [search resignFirstResponder];
  } else {
    [search becomeFirstResponder];
    [search resignFirstResponder];
  }
}

This does not solve the problem and i am not sure why the keyboard is not dismissing. For reference, when returning to the original ViewC1, ViewC3 is dismissed as follows:

UIViewController *parent = self.presentingViewController;
[parent.presentingViewController dismissViewControllerAnimated:YES completion:nil];

Any help is appreciated, thanks.

Okay i figured out what the problem was. They first responder was being resigned but the keyboard was not disappearing because of a focus issue. There is a default behaviour on modal views to not dismiss the keyboard (which is not a bug apparently). So after returning from the modal view it was still having this behaviour (resigning first responder but not dismissing keyboard). The way i solved this was by placing the following code in both the modal views .m files:

- (BOOL)disablesAutomaticKeyboardDismissal {
return NO;
}

This solved it for me. Then by either using:

[search resignFirstResponder];

or

[self.view endEditing: YES];

The keyboard will dismiss fine!

You'll need to do some debugging with break points to figure out why that conditional statement is not being hit. You could also use the endEditing method in UIView to simply resign the responder whenever search is clicked:

- (void) searchBarSearchButtonClicked:(UISearchBar *)search
        [search endEditing:YES];
}

Try it....

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

Please declare IBOutlet UISearchBar *mySearchBar; in your .h file
Set delegate in your .xib file.

Hope this helped
