UIBarButton not working when toolbar superview has UITapGestureRecognizers?

Question

I am experiencing this strange behavior.

I create a clean project (view template), add a toolbar with a button and hook it up with an action. it works ;) BUT, then when I add a UITapGestureRecognizer to the view of my viewcontroller the toolbar button stops working. (It is pressed but its action is not called) When I add the UITapGestureRecognizer only the action linked to it is called. It is like uitapgesture recognizer view were hiding the toolbar but actually is not.

What is happening here? What am I missing?

- (IBAction)itemAction{
    NSLog(@"%s", _cmd);
    self.view.backgroundColor = [UIColor whiteColor];
}
- (void) tapAction{
    NSLog(@"%s", _cmd);
    self.view.backgroundColor = [UIColor greenColor];
}
- (void)viewWasTapped:(UITapGestureRecognizer *)recognizer{
    if (recognizer.state == UIGestureRecognizerStateRecognized) {
        [self tapAction];
    }
}
- (void)viewDidLoad {
    [super viewDidLoad];
    UITapGestureRecognizer *tapGestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(viewWasTapped:)];
    [tapGestureRecognizer setNumberOfTapsRequired:1];
    [self.view addGestureRecognizer:tapGestureRecognizer];
    [tapGestureRecognizer release]; 
}

EDIT: the project source can be downloaded from here

Thanks in advance for any advice

Answer 1

I've encountered a similar problem, and found this answer quite helpful, especially because it allows selectively excluding the gesture recognizer based on the type of view that was touched.

Answer 2

Eventually I found the reason:

tapGestureRecognizer.cancelsTouchesInView = NO;
