I am integrating a Google AdMob banner ad into a UIView container that has the following constraints:

View Hierarchy

Main View (root view of UIViewController). Container View (inside Main View, used to hold adBannerView). adBannerView (added programmatically inside Container View).

UIViewController's Main View │ ├── Container View (UIView) │ ├── Ad Banner View (GADBannerView or other ad view)

Constraints Container View: Left: 0 (Aligns to the left of the main view) Right: 0 (Aligns to the right of the main view) Bottom: 0 (Sticks to the bottom of the main view) Height: 70 (Fixed height)

Ad Banner View: Same bounds as Container View (matches its frame)

  • Container View is pinned to the bottom of the screen.
  • Ad Banner View is programmatically added inside Container View and set to match its bounds.
  • When the ad is loaded, it appears inside Container View without affecting other UI elements.

Here is my code for adding the banner ad:

func showAd(bannerViewContainer: UIView, VC: UIViewController) {
    var bannerView: BannerView!
    bannerView = BannerView(adSize: AdSizeFullBanner)
    bannerView.adUnitID = bannerAdsId
    bannerView.rootViewController = VC
    
    bannerView.load(Request())
    bannerView.frame = bannerViewContainer.bounds
    bannerViewContainer.addSubview(bannerView)
}

However, when the ad appears on the screen, I notice that there is extra space on the left side of the banner. The banner is not aligned properly within the container view.

What I Have Tried:

  • Checked the constraints - The container view has proper constraints (0 on left, right, and bottom).
  • Set the banner frame explicitly - I tried manually setting bannerView.frame = bannerViewContainer.bounds, but the issue persists.
  • Tried different ad sizes - Using AdSizeBanner and AdSizeSmartBannerPortrait, but the issue remains.

Questions:

  • Why is there extra left padding in the banner ad when it's inside a container with full width?

  • It is recommended to change to the latest version of SDK or the corresponding functions and codes. stackoverflow.com/a/79551643/17373286 Also, the Admob in iOS is unstable in providing the top, bottom, left, and right margins/padding or positions of the ad unit from Google. This also depends on the design quality of each advertiser. Commented Apr 7 at 21:13
