How to detect touches in status bar

So this is my current solution, which works amazingly well. But please come with other ideas, as I don't really like it...

• Add a scrollview somewhere in your view. Maybe hide it or place it below some other view etc.
• Set its contentSize to be larger than the bounds
• Set a non-zero contentOffset
• In your controller implement a delegate of the scrollview like shown below.

By always returning NO, the scroll view never scrolls up and one gets a notification whenever the user hits the status bar. The problem is, however, that this does not work with a "real" content scroll view around. (see question)

- (BOOL)scrollViewShouldScrollToTop:(UIScrollView *)scrollView
{
    // Do your action here
    return NO;
}

Finally, i've assembled the working solution from answers here. Thank you guys.

Declare notification name somewhere (e.g. AppDelegate.h):

static NSString * const kStatusBarTappedNotification = @"statusBarTappedNotification";

Add following lines to your AppDelegate.m:

#pragma mark - Status bar touch tracking
- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [super touchesBegan:touches withEvent:event];
    CGPoint location = [[[event allTouches] anyObject] locationInView:[self window]];
    CGRect statusBarFrame = [UIApplication sharedApplication].statusBarFrame;
    if (CGRectContainsPoint(statusBarFrame, location)) {
        [self statusBarTouchedAction];
    }
}

- (void)statusBarTouchedAction {
    [[NSNotificationCenter defaultCenter] postNotificationName:kStatusBarTappedNotification
                                                        object:nil];
}

Observe notification in the needed controller (e.g. in viewWillAppear):

[[NSNotificationCenter defaultCenter] addObserver:self
                                         selector:@selector(statusBarTappedAction:)             
                                             name:kStatusBarTappedNotification
                                           object:nil];

Remove observer properly (e.g. in viewDidDisappear):

[[NSNotificationCenter defaultCenter] removeObserver:self name:kStatusBarTappedNotification object:nil];

Implement notification-handling callback:

- (void)statusBarTappedAction:(NSNotification*)notification {
    NSLog(@"StatusBar tapped");
    //handle StatusBar tap here.
}

Hope it will help.

Swift 3 update

Tested and works on iOS 9+.

Declare notification name somewhere:

let statusBarTappedNotification = Notification(name: Notification.Name(rawValue: "statusBarTappedNotification"))

Track status bar touches and post notification. Add following lines to your AppDelegate.swift:

override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    super.touchesBegan(touches, with: event)

    let statusBarRect = UIApplication.shared.statusBarFrame
    guard let touchPoint = event?.allTouches?.first?.location(in: self.window) else { return }

    if statusBarRect.contains(touchPoint) {
        NotificationCenter.default.post(statusBarTappedNotification)
    }
}

Observe notification where necessary:

NotificationCenter.default.addObserver(forName: statusBarTappedNotification.name, object: .none, queue: .none) { _ in
    print("status bar tapped")
}

Adding this to your AppDelegate.swift will do what you want:

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
    super.touchesBegan(touches, withEvent: event)
    let events = event!.allTouches()
    let touch = events!.first
    let location = touch!.locationInView(self.window)
    let statusBarFrame = UIApplication.sharedApplication().statusBarFrame
    if CGRectContainsPoint(statusBarFrame, location) {
        NSNotificationCenter.defaultCenter().postNotificationName("statusBarSelected", object: nil)
    }
}

Now you can subscribe to the event where ever you need:

NSNotificationCenter.defaultCenter().addObserverForName("statusBarSelected", object: nil, queue: nil) { event in

    // scroll to top of a table view
    self.tableView!.setContentOffset(CGPointZero, animated: true)
}
