Question

I am presenting a modal view controller as a form sheet and dismissing it when the cancel button, which is a bar button item, is clicked. I need to dismiss it when I tap on outside of that view. Please help me with a reference. Note: my modal view controller is presented with a navigation controller.

@cli_hlt, @Bill Brasky thanks for your answer. I need to dismiss it when tap occurs outside of the modal view which is a form sheet. I am pasting my code below.

-(void)gridView:(AQGridView *)gridView didSelectItemAtIndex:(NSUInteger)index  
{        
    if(adminMode) 
    {
        CHEditEmployeeViewController *editVC = [[CHEditEmployeeViewController alloc] initWithNibName:@"CHEditEmployeeViewController" bundle:nil];
        editVC.delegate = self;
        editVC.pickedEmployee = employee;
        editVC.edit = TRUE;
        editVC.delegate = self;
        UINavigationController *navigationController = [[UINavigationController alloc]initWithRootViewController:editVC];
        navigationController.modalPresentationStyle = UIModalPresentationFormSheet;
        [self presentModalViewController:navigationController animated:YES];

        return;
    }   //the above code is from the view controller which presents the modal     view. Please look at the below code too which is from my modal view controller. Please guide me in a proper way.   -(void)tapGestureRecognizer {

    UITapGestureRecognizer *recognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handleTapBehind:)];
    [recognizer setNumberOfTapsRequired:1];
    recognizer.cancelsTouchesInView = NO; //So the user can still interact with controls in the modal view
    [self.view addGestureRecognizer:recognizer];

}

- (void)handleTapBehind:(UITapGestureRecognizer *)sender
{
    if (sender.state == UIGestureRecognizerStateEnded) 
    {
        CGPoint location = [sender locationInView:nil]; //Passing nil gives us coordinates in the window

    //Then we convert the tap's location into the local view's coordinate system, and test to see if it's in or outside. If outside, dismiss the view.

        if (![self.view pointInside:[self.view convertPoint:location fromView:self.view.window] withEvent:nil]) 
        {
            [self dismissModalViewControllerAnimated:YES];
            [self.view.window removeGestureRecognizer:sender];
        }

    }
}

Ah ok. So I’m afraid thats not quite possible using the presentModalViewController: method. The whole idea of a “modal” view/window/message box/etc. pp. is that the user cannot do anything else than processing whatever the view/window/message box/etc. pp. wants him/her to do.

What you want to do instead is not present a modal view controller, but rather load and show your form view controller the regular way. Note in your master controller that the form is just showing e.g. with a BOOL variable and then handle there any taps that might occur. If your form is showing, dismiss it.
