Understanding and Implementing adBannerView over UITabBar

In this post, we’ll delve into the world of UIKit and explore how to successfully integrate an adBannerView over a UITabBar. We’ll take a step-by-step approach, discussing the necessary components, settings, and code snippets required to achieve this feat.

Understanding adBannerView and UITabBar

Before diving into the implementation, let’s briefly review what each component is and its purpose:

adBannerView

An adBannerView is a part of Apple’s iAd framework, which allows developers to easily integrate ads into their iOS applications. It provides a pre-built UI element for displaying banner-style ads.

UITabBar

The UITabBar is a part of the UIKit framework and serves as the tab bar for an application. It contains multiple tabs, each representing a different screen or view within the app.

Setting Up the Project

To implement adBannerView over a UITabBar, we’ll start by creating a new single-view app project in Xcode. This will give us a basic setup to work with.

Next, we need to add the necessary dependencies to our project:

Open your project’s target settings.
Navigate to the “General” tab.
Scroll down and locate the “Frameworks, Libraries, and Embedded Content” section.
Click the “+” button next to this section and select “iAd.framework”.
Click “Add”.

Understanding adBannerView Configuration

To display an adBannerView over a UITabBar, we need to configure it properly:

Setting the Ad Size

The adBannerView needs an ad size to be displayed effectively. We can set this by creating an instance of the ADFormatSpec class and specifying the desired width and height.

#import <AdSupport/ADFormatSpec.h>

// Define the ad format spec
ADFormatSpec *format = [[ADFormatSpec alloc] initWithSize:CGSizeMake(320, 44)];

Setting the Ad Image

We need to provide an image for our ad. This can be a URL or an actual image asset.

#import <iAd/iAd.h>

// Create an iAd instance and specify the ad image URL
iAd *ad = [[iAd alloc] initWithFormat:format];
[ad setAdUnitID:@"YOUR_AD_UNIT_ID"]; // Replace with your actual ad unit ID
NSString *imageUrl = @"https://example.com/ad-image.jpg";
ad.imageURL = [NSURL URLWithString:imageUrl];

Implementing adBannerView over UITabBar

Now that we have our adBannerView configured, let’s implement it over the UITabBar.

Creating an adBannerView Instance

First, create an instance of the ADBannerView class.

#import <AdSupport/ADBannerView.h>

// Create an instance of the ADBannerView
ADBannerView *bannerView = [[ADBannerView alloc] initWithFormat:format];

Adding the bannerView to the UITabBar

To display our adBannerView over the UITabBar, we need to add it as a subview to the tab bar’s window.

#import <UIKit/UIKit.h>

// Get the main window and add the banner view to it
[self.window.rootViewController.view addSubview:bannerView];

Resizing the adBannerView

To ensure our adBannerView is displayed correctly, we need to resize it according to the tab bar’s size.

#import <AdSupport/ADBannerView.h>

// Define a function to update the banner view frame
- (void)updateBannerViewFrame {
    bannerView.frame = CGRectMake(0, self.tabBar.height - 44, bannerView.bounds.size.width, 44);
}

Implementing adBannerView under UITableViewCell

To display our adBannerView under each cell in a table view, we’ll create a custom table view cell class.

Custom Table View Cell Class

First, create a new file called Cell.h and add the following code:

#import <UIKit/UIKit.h>

@interface MyTableViewCell : UITableViewCell

@property (nonatomic, strong) ADBannerView *bannerView;

@end

Next, create a corresponding implementation file called Cell.m:

#import "Cell.h"

@implementation MyTableViewCell

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {
        // Initialize the banner view
        _bannerView = [[ADBannerView alloc] initWithFormat:[[ADFormatSpec alloc] initWithSize:CGSizeMake(320, 44)]];
        _bannerView.frame = CGRectMake(0, self.bounds.size.height - 44, self.bounds.size.width, 44);
    }
    return self;
}

- (void)layoutSubviews {
    [super layoutSubviews];

    // Update the banner view frame
    self.bannerView.frame = CGRectMake(0, self.bounds.size.height - 44, self.bounds.size.width, 44);
}

Displaying adBannerView under UITableViewCell

To display our adBannerView under each cell in a table view, we’ll need to update the table view’s delegate method.

#import <UIKit/UIKit.h>

@interface MyViewController : UIViewController <UITableViewDataSource, UITableViewDelegate>

@end

@implementation MyViewController

- (void)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    // Create a new instance of our custom table view cell
    MyTableViewCell *cell = [[MyTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"Cell"];

    // Update the ad banner view's frame according to the cell size
    [cell.bannerView setBannerViewFrame:CGRectMake(0, cell.bounds.size.height - 44, cell.bounds.size.width, 44)];

    // Add the banner view to the cell's subviews
    [cell.bannerView addSubview:tableView];

    return cell;
}

@end

Conclusion

In this article, we’ve explored how to display an adBannerView over a UITabBar. We’ve covered setting up the necessary dependencies, configuring the ad banner view, and implementing it over the UITabBar. Additionally, we’ve discussed displaying the ad banner view under each cell in a table view.

By following these steps and customizing our implementation to fit your specific needs, you should now be able to successfully display an adBannerView over a UITabBar in your iOS application.
