Implementation of ADBannerView on storyboard with autolayout

Question

I have Xcode 6.3.2 and I have a problem with implementation of ADBannerView on storyboard. Xcode shows all the time a warning:

Frame for "Banner View" will be different at run time.

I added 3 constraints, you can see them below.

All of constraints Center horizontally Bottom space to bottom layout guide = 0 Bottom constraint Leading space = 0 enter image description here

How to implement banner correctly?

I can not use "self.canDisplayBannerAds = true" because I also use "bannerViewDidLoadAd" and "didFailToReceiveAdWithError" to resize content and also "bannerViewActionShouldBegin" and "bannerViewActionDidFinish" to pause and start again application activity.

SOLVED!

To add iAd banner using Auto Layout and Size Classes in portrait and landscape but without using canDisplayBannerAds first declare banner var bannerView: ADBannerView!.

Use this to set delegate and add banner to view:

func loadAds() {
    bannerView = ADBannerView(adType: ADAdType.Banner)
    bannerView.hidden = true
    bannerView.delegate = self
    self.view.addSubview(bannerView)
}

Use following code to let banner rotate with screen and resize screen content contentView when iAd loads (bottomConstraint is a constraint from contentView to bottom):

override func viewDidLayoutSubviews() {
    self.layoutAnimated(UIView.areAnimationsEnabled())
}

func layoutAnimated(animated: Bool) {
    var contentFrame = self.view.bounds

    var sizeForBanner = bannerView.sizeThatFits(contentFrame.size)

    var bannerFrame = bannerView.frame
    if self.bannerView.bannerLoaded {

        contentFrame.size.height -= sizeForBanner.height
        bannerFrame.origin.y = contentFrame.size.height
        bannerFrame.size.height = sizeForBanner.height
        bannerFrame.size.width = sizeForBanner.width

        let verticalBottomConstraint = self.bottomConstraint
        verticalBottomConstraint.constant = sizeForBanner.height
        self.view.layoutSubviews()
        bannerView.hidden = false
    } else {
        bannerFrame.origin.y = contentFrame.size.height
        bannerView.hidden = true
        let verticalBottomConstraint = self.bottomConstraint
        verticalBottomConstraint.constant = 0
    }
    UIView.animateWithDuration(animated ? 0.25 : 0.0, animations: {
        self.contentView.layoutIfNeeded()
        self.bannerView.frame = bannerFrame
    })
}

Here you call above code to show and hide banner when loads or failed to load iAd

func bannerViewDidLoadAd(banner: ADBannerView!) {
    self.layoutAnimated(true)
}

func bannerView(banner: ADBannerView!, didFailToReceiveAdWithError error: NSError!) {
    self.layoutAnimated(true)
}

Now you can use bannerViewActionShouldBegin and bannerViewActionDidFinish to pause and start your app activity. :)

I believe this is an Auto Layout issue for ADBannerView's. I implement my ADBannerView's in a similar manner and I've been unable to find a way to silence the warning while at the same time satisfying the flexibility required for my ADBannerView. Implementing an AdMob GADBannerView in the same exact way does not cause an Auto Layout warning to occur. As you can see in my screen shot, the ADBannerView will indeed be stretched across the devices screen, width = 600, but Auto Layout still thinks it is at the default size, width = 480.

The best answer at this time is to simply ignore the warning.
