- (void)sendAction:(SEL)action to:(nullable id)target forEvent:(nullable UIEvent *)event {
  [super sendAction:action to:target forEvent:event];
  [[UIApplication sharedApplication] beginIgnoringInteractionEvents];
  dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.2 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
    [[UIApplication sharedApplication] endIgnoringInteractionEvents];
  });
}
