Added delegate method to notify when left view is overlapped by right vi...

I need ability to know when right views are positioned in such way that left menu view is overlapped (to be able make some animations on left view depending on overlaps). Added delegate method so now it is possible to know the overlapping status.

I think a delegate method is the wrong approach for this because this is a property for the current state of an ANAdvancedNavigationController instance.

How about a new property -[ANAdvancedNavigationController isFirstViewControllerViewOverlappingWith...] or -[ANAdvancedNavigationController isFirstViewControllerViewOverdraggedToLeft]?

You are right, state property will be better approach here I think. I just will setup KVO to track the changes.
Removed delegate things and added isFirstViewControllerViewOverdraggedToLeft property instead.

Am i correct that the property isFirstViewControllerViewOverdraggedToLeft now only returns valid results if a view controller is pushed or popped? How about something like

- (BOOL)isFirstViewControllerViewOverdraggedToLeft
{
  if (self.viewControllers.count > 0) {
    UIViewController *firstRightViewController = self.viewControllers[0];
    return firstRightViewController.view.superview.frame.origin.x <= ANAdvancedNavigationControllerDefaultLeftPanningOffset;
  }
  return NO;
}

and maybe make it kvo conform while the user is panning?

Added isFirstViewControllerViewOverdraggedToLeft getter and status updating while panning to __mainPanGestureRecognizedDidRecognizePanGesture.

Is the iVar still needed? I thought - (BOOL)isFirstViewControllerViewOverdraggedToLeft {...} now always contains a valid result.

isFirstViewControllerViewOverdraggedToLeft property is readonly and I need somehow update it before sending KVO notifications. Not sure how to do that without ivar. Could you advice?

[xzenon]

Added value tracking so KVO notifications are not generated when overlap status unchanged.
