Banner

Banner ads are classic static banners, usually located at the bottom or top of the screen. Appodeal supports traditional 320x50 banners, 728x90 tablet banners and smart banners that adjust to the size and orientation of the device.

You can use our demo app as a reference project.

Demo App

Fixed Positioned Banner

Display Banner At The Bottom Of The Screen

Banner is a singleton now, if you are using bannerTop or bannerBottom on different controllers, the SDK will use the same banner instance.

Banner ads are refreshed every 15 seconds automatically by default. To display a banner, you need to call the following code:

Appodeal.showAd(.bannerBottom, rootViewController: self)

Display Banner At The Top Of The Screen

Appodeal.showAd(.bannerTop, rootViewController: self)

Display Banner At The Left Or Right Corner Of The Screen

If your app uses landscape interface orientation you can show Appodeal Banner at the left or right corner. The banner will have the offset according to the safe area layout guide.

caution

Disable banner smart sizing if you use AppodealShowStyleBannerLeft or AppodealShowStyleBannerRight

// Overrides default rotation angles
// Appodeal.setBannerLeftRotationAngleDegrees(90, rightRotationAngleDegrees: 180)


Appodeal.showAd(.bannerLeft, forPlacement: placement, rootViewController: self)
// Appodeal.showAd(.bannerRight, forPlacement: placement, rootViewController: self)

Checking If Ad Is Loaded

You can check if the ad has been loaded before showing it. This method returns a boolean value indicating whether or not the banner has been loaded.

Appodeal.isReadyForShow(with: .bannerTop)

We recommend you to check ad caching before trying to show it.

Callbacks

Callbacks are used to track different lifecycle events of an ad, e.g., when a banner has successfully loaded or is about to appear. To get them, you need to set the delegate as follows:

//set delegate
Appodeal.setBannerDelegate(self)

Usually, the class that implements banners is also the delegate class. That's why the delegate property can be set to self.

Now you can use the following callback methods:

// banner was loaded (precache flag shows if the loaded ad is precache)
func bannerDidLoadAdIsPrecache(_ precache: Bool) {}
// banner was shown
func bannerDidShow() {}
// banner failed to load
func bannerDidFailToLoadAd() {}
// banner was clicked
func bannerDidClick() {}
// banner did expire and could not be shown
func bannerDidExpired() {}
tip

All callbacks are called on the main thread.

caution

If automatic caching is ON for the Banner ad type, do not show the banner in the bannerDidLoadAdIsPrecache callback. The banner will be refreshed automatically after the first show.

Hide

To remove the banner from your view hierarchy:

Appodeal.hideBanner()

Custom Positioned Banner

Display Banner In Programmatically Created View

You can also add the Appodeal banner to your view hierarchy manually.

For example:

override func viewWillAppear(_ animated: Bool) {
super.viewWillAppear(animated)
if let banner = Appodeal.banner() {
self.view.addSubview(banner)
banner.frame = CGRect(x: 0, y: 0, width: self.view.bounds.width, height: 50)
}
}

Important!

Custom BannerView must be on the top of the hierarchy and mustn't be overlapped by other views.

Advanced

Placements

Appodeal SDK allows you to tag each impression with different placement. To be able to use placements, you need to create them in Appodeal Dashboard. Read more about placements.

Appodeal.showAd(.bannerTop, forPlacement: placement, rootViewController: self)

If the loaded ad can't be shown in a specific placement, nothing will be shown. If auto caching is enabled, the SDK will start to cache another ad, which can affect display rate. To save the loaded ad for future use (for instance, for another placement) check if the ad can be shown before calling show method:

Appodeal.canShow(.bannerTop, forPlacement: placement)

You can configure your impression logic for each placement.

If you have no placements or call Appodeal.show with a placement that does not exist, the impression will be tagged with 'default' placement with corresponding settings applied.

Important!

Placement settings affect ONLY ad presentation, not loading or caching.

Check If Banner Is Initialized

Appodeal.isInitialized(for: .banner)

Returns true if banner was initialized.

Check If Autocache Is Enabled

Appodeal.isAutocacheEnabled(.banner)

Returns true if autocache is enabled for banner.

Advanced BannerView Integration

If basic integration is not appropriate for you due to the complex views hierarchy of your app, you can use AppodealBannerView UIView subclass to integrate banners.

import UIKit
import Appodeal

class YourViewController : UIViewController, AppodealBannerViewDelegate {

override func viewDidLoad () {
super.viewDidLoad()
// required: init ad banner
var bannerView: AppodealBannerView!
bannerView.init(size: bannerSize, rootViewController: self);

// optional: set delegate
bannerView.setDelegate(self);

// required: add banner to superview and call -loadAd to start banner loading
self.view addSubview(bannerView);
bannerView.loadAd();
}

// optional: implement any of AppodealBannerViewDelegate methods
func bannerViewDidLoadAd(_ bannerView: APDBannerView, isPrecache precache: Bool) {
NSLog("bannerView was loaded")
}

func bannerView(_ bannerView: APDBannerView, didFailToLoadAdWithError error: Error) {
NSLog("bannerView failed to load");
}

func bannerViewDidInteract(_ bannerView: APDBannerView) {
NSLog("bannerView was clicked")
}

func bannerViewDidShow(_ bannerView: APDBannerView) {
NSLog("bannerView was shown")
}

func bannerViewExpired(_ bannerView: APDBannerView) {
NSLog("bannerView did expire and could not be shown")
}
}
tip

To provide better user expirience we recommend to use single banner instance for all you screens where banner is shown.

There are several examples how to properly pass banner instance between screens using UIStoryboardSegue and in-code navigation through UINavigationController.

Storyboard based application example.

  1. Create auxiliary protocol that will layout banner view in View Controller's view. In this example we will layout at the bottom of screen.
BannerContainableController.swift
import Foundation
import UIKit
import Appodeal


protocol BannerContainableController: UIViewController {
var bannerContainerView: UIView! { get }
}

extension BannerContainableController {
func layoutBannerView(_ bannerView: APDBannerView) {
bannerView.removeFromSuperview()
bannerView.rootViewController = self
bannerContainerView.addSubview(bannerView)

NSLayoutConstraint.activate([
bannerView.topAnchor.constraint(equalTo: bannerContainerView.topAnchor),
bannerView.bottomAnchor.constraint(equalTo: bannerContainerView.bottomAnchor),
bannerView.leftAnchor.constraint(equalTo: bannerContainerView.leftAnchor),
bannerView.rightAnchor.constraint(equalTo: bannerContainerView.rightAnchor),
])
}
}

This protocol will be used in both ParentViewController and ChildViewController to layout banner view.

  1. Create new seque in storyboard with identifier: ShowChildViewController
  1. Override prepare(for segue:, sender:) method in ParentViewController and pass banner instance to ChildViewController.
ParentViewController.swift

import UIKit
import Appodeal


class ParentViewController: UIViewController, BannerContainableController {
@IBOutlet weak var bannerContainerView: UIView!

private lazy var bannerView = APDBannerView(size: kAPDAdSize320x50)

override func viewDidLoad() {
super.viewDidLoad()
// Load banner and it to the view in hierarchy
bannerView.loadAd()
bannerView.translatesAutoresizingMaskIntoConstraints = false
layoutBannerView(bannerView)
}

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
guard
segue.identifier == "ShowChildViewController",
let childViewController = segue.destination as? ChildViewController
else { return }

childViewController.onDismiss = { [weak self] in
guard let self else { return }
self.layoutBannerView(self.bannerView)
}

childViewController.bannerView = bannerView
}
}

  1. When user returns to ParentViewController we need to pass back banner view. To achieve this we will use onDismiss callback.
ChildViewController.swift
import Foundation
import UIKit
import Appodeal


class ChildViewController: UIViewController, BannerContainableController {
@IBOutlet weak var bannerContainerView: UIView!

weak var bannerView: APDBannerView?

var onDismiss: (() -> ())?

override func viewDidLoad() {
super.viewDidLoad()
guard let bannerView = bannerView else { return }
layoutBannerView(bannerView)
}

override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
onDismiss?()
}
}

UINavigationController based application example.

  1. Create auxiliary protocol that will layout banner view in View Controller's view. We will use the same implementation from the previous storyboard example.

  2. In ParentViewController create new instance of ChildViewController and pass banner instance to it.

ParentViewController.swift
import UIKit
import Appodeal


class ParentViewController: UIViewController, BannerContainableController {
private lazy var bannerView = APDBannerView(size: kAPDAdSize320x50)

override func viewDidLoad() {
super.viewDidLoad()
self.navigationItem.title = "Root View Controller"

bannerView.translatesAutoresizingMaskIntoConstraints = false

bannerView.rootViewController = self
bannerView.loadAd()

layoutBannerView(bannerView)

setupNavigationButton()
}

func setupNavigationButton() {
var configuration = UIButton.Configuration.filled()
configuration.titlePadding = 16
configuration.imagePadding = 16

let button = UIButton(configuration: configuration)
button.setImage(UIImage(systemName: "chevron.right"), for: .normal)
button.setTitle("Go To The Next View Controller", for: .normal)
button.translatesAutoresizingMaskIntoConstraints = false
button.addTarget(self, action: #selector(navigateToChildrenViewController), for: .touchUpInside)

view.addSubview(button)

NSLayoutConstraint.activate([
button.centerYAnchor.constraint(equalTo: view.centerYAnchor),
button.centerXAnchor.constraint(equalTo: view.centerXAnchor),
button.heightAnchor.constraint(equalToConstant: 44)
])
}

@objc func navigateToChildrenViewController() {
let destinationViewController = ChildViewController()
destinationViewController.layoutBannerView(bannerView)
destinationViewController.onDismiss = { [weak self] in
guard let self = self else { return }
self.layoutBannerView(self.bannerView)
}
navigationController?.pushViewController(destinationViewController, animated: true)
}
}
  1. In ChildViewController we will use the same approach to pass back banner view on dismiss using closure.
import UIKit

class ChildViewController: UIViewController, BannerContainableController {
var onDismiss: (() -> ())?

override func viewDidLoad() {
super.viewDidLoad()
}

override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(animated)
onDismiss?()
}
}

BannerView in SwifUI based application

As for UIKit based application for SwiftUI we recommend to use single banner instance for all you screens where banner is shown.

To achieve this behaviour you need to implement several auxiliary classes.

  1. Create APDBannerViewController that will be using for banner view layout and controlling of a view lifecycle
APDBannerViewController.swift
import UIKit
import Appodeal

final class APDBannerViewController: UIViewController {
weak var bannerView: APDBannerView?

var onDismiss: (() -> ())?

override func viewDidLoad() {
super.viewDidLoad()
layoutBannerView()
}

deinit {
onDismiss?()
}

func layoutBannerView() {
guard let bannerView = bannerView else { return }

bannerView.removeFromSuperview()
bannerView.rootViewController = self
view.addSubview(bannerView)

NSLayoutConstraint.activate([
bannerView.topAnchor.constraint(equalTo: view.topAnchor),
bannerView.bottomAnchor.constraint(equalTo: view.bottomAnchor),
bannerView.leftAnchor.constraint(equalTo: view.leftAnchor),
bannerView.rightAnchor.constraint(equalTo: view.rightAnchor),
])
}
}

  1. Create BannerView - a view that will implement UIViewControllerRepresentable protocol and will be used in SwiftUI views hierarchy. Also we need to implement custom Coordinator (singleton in this case) that uses NSHashTable to store to manage APDBannerViewController instances.
BannerView.swift
import SwiftUI


struct BannerView: UIViewControllerRepresentable {
typealias UIViewControllerType = APDBannerViewController

func makeUIViewController(context: Context) -> APDBannerViewController {
let controller = APDBannerViewController()
controller.bannerView = context.coordinator.bannerView
controller.onDismiss = context.coordinator.dismiss
context.coordinator.store(controller)
return controller
}

func updateUIViewController(
_ uiViewController: APDBannerViewController,
context: Context
) {}

func makeCoordinator() -> Coordinator {
return .shared
}

final class Coordinator {
static let shared = Coordinator()

private lazy var storage = NSHashTable<APDBannerViewController>(options: .weakMemory)

lazy var bannerView: APDBannerView = {
let bannerView = APDBannerView(size: kAPDAdSize320x50)
bannerView.translatesAutoresizingMaskIntoConstraints = false
bannerView.loadAd()
return bannerView
}()

func store(_ controller: APDBannerViewController) {
storage.add(controller)
}

func dismiss() {
let previousController = storage.allObjects.last

previousController?.bannerView = bannerView
previousController?.layoutBannerView()
}
}
}

  1. Now we can use BannerView in SwiftUI views hierarchy.
caution

BannerView is requred to have frame with fixex height.

ContentView.swift
import SwiftUI


struct ContentView: View {
var body: some View {
NavigationStack {
VStack {
BannerView()
.frame(height: 50)
.frame(maxWidth: .infinity)
.background(Color(uiColor: .secondarySystemFill))
Spacer()
NavigationLink(
destination: {
ChildView()
},
label: {
HStack {
Image(systemName: "chevron.right")
Text("Go To The Next View")
}
.foregroundColor(.white)
.padding()
.background(RoundedRectangle(cornerRadius: 8).fill(Color.blue))
}
)
}
.navigationTitle("Root View")
}
}
}


struct ChildView: View {
var body: some View {
NavigationStack {
VStack {
Spacer()
BannerView()
.frame(height: 50)
.frame(maxWidth: .infinity)
.background(Color(uiColor: .secondarySystemFill))
}
.navigationTitle("Child View")
}
}
}


Enable Smart Banners

Smart banners are banner ads which automatically fit the screen/container size. Using them helps to deal with increasing fragmentation of the screen sizes on different devices. To enable them, use the following method:

//for top/bottom banners allows banner view to resize automatically to fit device screen
Appodeal.setSmartBannersEnabled(true)
//for banner view allows banner view to resize automatically to fit device screen
bannerView.usesSmartSizing = true

Change Banner Background

This method allows to create a grey background for banner ads:

//for top/bottom banners
Appodeal.setBannerBackgroundVisible(true)

//for bannerView
bannerView.backgroundVisible = true

Enable Banner Refresh Animation

//for top/bottom banners
Appodeal.setBannerAnimationEnabled(true)

//for bannerView
bannerView.bannerAnimationEnabled = true

Get Predicted eCPM

This method returns the expected eCPM for the cached ad. The amount is calculated based on historical data for the current ad unit.

Appodeal.predictedEcpm(for: .banner)
