Dismiss ModalViewController with NavigationController in iPad When tap outside the view - ios

Question

So I am usually follow this way to dismiss ModalViewController when tap outside its view
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
if(UIUserInterfaceIdiomPad == UI_USER_INTERFACE_IDIOM())
{
if(![self.view.window.gestureRecognizers containsObject:recognizer])
{
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.window addGestureRecognizer:recognizer];
[recognizer release];
}
}
}
- (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:recognizer];
}
}
}
its working good with regular ModalViewController .. but now I have a modelViewController which is a NavigationViewController with "x" viewController as the root one .. when I use this way and tap on the navigationBar the controller is dismissed , or when I navigate to "y" controller from x controller and want to get back , also when I click the back button the ModalView is dismissed ! which is wrong behavior to me .. I just want the controller to be dismissed in case the tap was completely outside the controller (view area + navigationBar area) .. any one can provide a help please ?

Update your code following:
- (void)handleTapBehind:(UITapGestureRecognizer *)sender
{
if (sender.state == UIGestureRecognizerStateEnded)
{
CGPoint flocation = [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.
CGPoint tap = [self.view convertPoint:flocation fromView:self.view.window];
CGPoint tapBar = [self.navigationController.navigationBar convertPoint:flocation fromView:self.view.window];
if (![self.view pointInside:tap withEvent:nil] && ![self.navigationController.navigationBar pointInside:tapBar withEvent:nil])
{
// Remove the recognizer first so it's view.window is valid.
[self.view.window removeGestureRecognizer:sender];
[self dismissModalViewControllerAnimated:YES];
}
}
}
Remove UITapGestureRecognizer from window when tap on UIBarButtonItem
-(void)viewWillDisappear:(BOOL)animated {
[self.view.window removeGestureRecognizer:self.tapOutsideGestureRecognizer];
}
