How do I prevent an event (such as touched) from being passed to the parent Superview?

Question

iOS

In general, there is a parent View (Room Scheme View).
There is a child leaving translucent TableView.
Now after tap(select) in TableView, this tap is passed on to the parent View(Room Scheme View)
How to make sure that this tap is not passed to the parent View(Room Scheme View)?

Maybe this will help you?

Answer 2

The information you provided is not enough. Therefore, a tap cannot simply be transmitted to the parent. Which is exactly what I just checked. Check on which views the tap happens, for example, in this controller method.

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
        for touch in touches {
            print(touch.view)
        }
    }

Temporarily solved the problem like this:
RoomSchemeView.h:

/// необрабатываемая зона, в этой области тапы не обрабатываются
@property (nonatomic, assign) CGRect unprocessedRect;

RoomSchemeView.m

- (void)tap:(UIGestureRecognizer *)gr
{
    CGPoint point = [gr locationInView:self];
    // проверяем находится ли точка в необрабатываем зоне
    if (!CGRectEqualToRect(self.unprocessedRect, CGRectZero) && CGRectContainsPoint(self.unprocessedRect, point)) {
        NSLog(@"tap with point %@ in unprocessed rect %@", NSStringFromCGPoint(point), NSStringFromCGRect(self.unprocessedRect));
        return;
    }
    ...
}

RoomSchemeViewController.m:

- (void)showTableView
{
    if (!self.tableIsVisible) {
        self.tableView.frame = CGRectMake(-self.tableView.frame.size.width, self.tableView.frame.origin.y, self.tableView.frame.size.width, self.tableView.frame.size.height);
        [UIView animateWithDuration:.3 animations:^{
            self.tableView.frame = CGRectMake(0, self.tableView.frame.origin.y, self.tableView.frame.size.width, self.tableView.frame.size.height);
        } completion:^(BOOL finished) {
            self.tableIsVisible = YES;
            self.roomSchemeView.unprocessedRect = self.tableView.frame;
        }];
    }
}

- (void)hideTableView
{
    if (self.tableIsVisible) {
        self.tableView.frame = CGRectMake(0, self.tableView.frame.origin.y, self.tableView.frame.size.width, self.tableView.frame.size.height);
        [UIView animateWithDuration:.3 animations:^{
            self.tableView.frame = CGRectMake(-self.tableView.frame.size.width, self.tableView.frame.origin.y, self.tableView.frame.size.width, self.tableView.frame.size.height);
        } completion:^(BOOL finished) {
            self.tableIsVisible = NO;
            self.roomSchemeView.unprocessedRect = CGRectZero;
        }];
    }
}
