Banner Integration for iOS

Banners are rectangular, system-initiated ads that can be either static or animated, and are served in a designated area around your live app content.

Step 1. Implement the Delegate

The ironSource SDK fires several delegate methods to inform you of Banner activity. The SDK will notify your delegate methods of all possible events listed below:

#pragma mark - ISBannerDelegate
/** Called after a banner ad has been successfully loaded
 */
- (void)bannerDidLoad:(ISBannerView *)bannerView {
dispatch_async(dispatch_get_main_queue(), ^{
        self.bannerView = bannerView;
        self.bannerView.translatesAutoresizingMaskIntoConstraints = NO;
       
        CGFloat y = self.view.frame.size.height - (self.bannerView.frame.size.height / 2);
        if (@available(ios 11.0, *)) {
            y -= self.view.safeAreaInsets.bottom;
        }
        self.bannerView.center = CGPointMake(self.view.frame.size.width / 2, y);
       
        [self.view addSubview:self.bannerView];
    });
}
/**
 Called after a banner has attempted to load an ad but failed.
 
 @param error The reason for the error
 */
- (void)bannerDidFailToLoadWithError:(NSError *)error {}
/**
 Called after a banner has been clicked.
 */
- (void)didClickBanner {}
/**
 Called when a banner is about to present a full screen content.
 */
- (void)bannerWillPresentScreen {}
/**
 Called after a full screen content has been dismissed.
 */
- (void)bannerDidDismissScreen {}
/**
 Called when a user would be taken out of the application context.
 */
- (void)bannerWillLeaveApplication {}

/MARK: Banner Delegates
    
   /**
     Called after a banner ad has been successfully loaded
     */
    func bannerDidLoad(_ bannerView: ISBannerView!)
    
   /**
     Called after a banner has attempted to load an ad but failed.
     @param error The reason for the error
     */
    func bannerDidFailToLoadWithError(_ error: Error!)
   /**
     Called after a banner has been clicked.
     */
    func didClickBanner()
    
   /**
     Called when a banner is about to present a full screen content.
     */
    func bannerWillPresentScreen()
   /**
     Called after a full screen content has been dismissed.
     */
    func bannerDidDismissScreen()
    
   /**
     Called when a user would be taken out of the application context.
     */
    func bannerWillLeaveApplication()

Step 2. Load Banner Ad

To load a banner ad, call the following method:

• Initiate the Banner view by calling this method (in this example it’s the BANNER banner size):
  
  • Objective-C
  • Swift

  [IronSource loadBannerWithViewController:self size:ISBannerSize_BANNER];

  See table below for details about our supported standard banner sizes:

  ISBannerSize	Description	Dimensions in points (WxH)
  ISBannerSize_BANNER	Standard Banner	320 x 50
  ISBannerSize_LARGE	Large Banner	320 x 90
  ISBannerSize_RECTANGLE	Medium Rectangular Banner	300 x 250
  ISBannerSize_SMART	Smart Banner (Adjusted for both iPhone and iPad)	If (screen height ≤ 720) 320 x 50 If (screen height > 720) 728 x 90

• Another option is initiating the banner with Custom size, using this signature (WxH in points):
  
  • Objective-C
  • Swift

  [IronSource loadBannerWithViewController:self size:[[ISBannerSize alloc] initWithWidth:320 andHeight:50];

Create and load a banner ad:

Here’s an example that initiates and loads a banner in the viewDidLoad method:

#import "ViewController.h"
#import <IronSource/IronSource.h>
 
@interface ViewController () <ISBannerDelegate>
 
@property (nonatomic, strong) ISBannerView      *bannerView;
 
@end
 
@implementation ViewController
 
- (void)viewDidLoad {
    [super viewDidLoad];
 
    [IronSource setBannerDelegate:self];
    [IronSource initWithAppKey:@"YOUR_APP_KEY" adUnits:@[IS_BANNER]];
   
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(orientationChanged:)
                                                 name:@"UIDeviceOrientationDidChangeNotification"
                                               object:nil];
   
    [IronSource loadBannerWithViewController:self size:ISBannerSize_BANNER];
}
 
#pragma mark - Orientation delegate
- (void)orientationChanged:(NSNotification *)notification {
    dispatch_async(dispatch_get_main_queue(), ^{
        if (self.bannerView) {
            CGFloat y = self.view.frame.size.height - (self.bannerView.frame.size.height / 2);
            if (@available(ios 11.0, *)) {
                y -= self.view.safeAreaInsets.bottom;
            }
            self.bannerView.center = CGPointMake(self.view.frame.size.width / 2, y);
        }
    });
}
 
#pragma mark - Banner Delegate Functions
- (void)bannerDidLoad:(ISBannerView *)bannerView {
    dispatch_async(dispatch_get_main_queue(), ^{
        self.bannerView = bannerView;
        self.bannerView.translatesAutoresizingMaskIntoConstraints = NO;
       
        CGFloat y = self.view.frame.size.height - (self.bannerView.frame.size.height / 2);
        if (@available(ios 11.0, *)) {
            y -= self.view.safeAreaInsets.bottom;
        }
        self.bannerView.center = CGPointMake(self.view.frame.size.width / 2, y);
       
        [self.view addSubview:self.bannerView];
    });
}
 
- (void)bannerDidFailToLoadWithError:(NSError *)error {
}
 
- (void)didClickBanner {
}
 
- (void)bannerWillPresentScreen {
}
 
- (void)bannerDidDismissScreen {
}
 
- (void)bannerWillLeaveApplication {
}
 
@end

Step 3. Additional Load Settings

We support placements, pacing and capping for Banners on the ironSource dashboard. Learn how to set up placements, capping and pacing for Banners to optimize your app’s user experience here.

If you’ve set up placements for your Banner, call the following method to serve a Banner ad in a specific placement:

[IronSource loadBannerWithViewController:self size:ISBannerSize_BANNER placement:placement];

IronSource.loadBanner(with: YOUR_VIEW_CONTROLLER, size: YOUR_BANNER_SIZE, placement: YOUR_PLACEMENT_NAME)

Step 4. Destroy the Banner Ad

To destroy a banner, call the following method:

[IronSource destroyBanner: bannerView];

IronSource.destroyBanner(YOUR_IRONSOURCE_BANNER)

A destroyed banner can no longer be loaded. If you want to serve it again, you must initiate it again.

Step 5.  Integrate a Banner Provider

Next, integrate the ad network adapters to serve Banners through ironSource Mediation. We currently support ironSource, Admob, AppLovin, Facebook, Fyber and Inmobi Banners.

For better understanding of bannerSize’s behaviour per network, please follow table:

Done!
You are now all set up to serve Banners in your application. Verify your integration with our Integration Helper.
