How to detect the location of taps in ios 7

I have a view controller with half table view (bottom, 320x289)and half map view (top, 320,289). How can I detect location of tap?

Currently my code for the tap looks like this - when tapping, it hides the navigation bar so that the map gets some extra real estate. However, because it's not detecting location of the tap, when I tap on the tableview, I'm not able to segue into my table view controller. 

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hideShowNavigation)];
tap.numberOfTapsRequired = 1;
[self.view addGestureRecognizer:tap];

Ideally I would like to detect location of taps. If tapped at the top (if height <=289px), it hides navigation bar (or maybe even segue into a separate view controller where map is full screen). If tapped at the bottom (if height > 289px), then it pushes the segue into table view controller.

- (void) hideShowNavigation:(id)sender
{
    [self.navigationController setNavigationBarHidden:!self.navigationController.navigationBarHidden];

    [self hidesBottomBarWhenPushed];
}

Here's the whole code:

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    self.navigationController.navigationBar.translucent = YES;
    self.automaticallyAdjustsScrollViewInsets = YES;

    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hideShowNavigation:)];
        tap.numberOfTapsRequired = 1;
        [self.view addGestureRecognizer:tap];    
}

- (void) hideShowNavigation:(id)sender
{
    CGPoint = [sender locationInView:self.view];
    CGFloat y = location.y;

    if(y<=289){
        [self.navigationController setNavigationBarHidden:!self.navigationController.navigationBarHidden];

        [self hidesBottomBarWhenPushed];
    }
}

In your selector:

CGPoint location = [sender locationInView:self.view];
CGFloat x = location.x;
CGFloat y = location.y;
