Why does iAd banner interferes with my UIView animations - ios

Question

I have an iAd that I created following this tutorial and for some reason when the iAd shows-up any animation going on at that time stops. In other words the animations work fine until the iAd apears and as soon as the iAd apears any animation going at that moment stops or it goes back to its original position without finishing the animation.
This is the code I have for the iAd
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
_adBanner = [[ADBannerView alloc] initWithFrame:CGRectMake(0, self.view.frame.size.height, 320, 50)];
_adBanner.delegate = self;
}
- (void)bannerViewDidLoadAd:(ADBannerView *)banner
{
if (!_bannerIsVisible)
{
if (_adBanner.superview == nil)
{
[self.view addSubview:_adBanner];
}
[UIView beginAnimations:#"animateAdBannerOn" context:NULL];
banner.frame = CGRectOffset(banner.frame, 0, -banner.frame.size.height);
[UIView commitAnimations];
_bannerIsVisible = YES;
}
}
- (void)bannerView:(ADBannerView *)banner didFailToReceiveAdWithError:(NSError *)error
{
if (_bannerIsVisible)
{
[UIView beginAnimations:#"animateAdBannerOff" context:NULL];
banner.frame = CGRectOffset(banner.frame, 0, banner.frame.size.height);
[UIView commitAnimations];
_bannerIsVisible = NO;
}
}
And this is one of the animations I have
- (IBAction)showHideBlackboard:(id)sender
{
[UIView animateWithDuration:0.6 delay: 0.0 options: UIViewAnimationOptionCurveEaseIn animations:^
{
self.controlsView.frame= CGRectMake(10, 10, 250, 250);
}completion:^(BOOL finished)
{
[UIView animateWithDuration:0.6 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^
{
self.drawingView.alpha = 1.0;
self.drawingView.frame= CGRectMake(10, 10, 350, 350);
}completion:nil ];
}];
}
Any idea why does the iAd interferes with UIView animations?

I recently had a similar problem. It turned out that avoiding the option
self.translatesAutoresizingMaskIntoConstraints = NO;
in my UIView subclass solved the problem.
