Swift Equivalent of Objective-C for Flutter Native Ads


I want to implement Native Ads for my Flutter project(It's using Swift, not Objective-C)

https://developers.google.com/admob/flutter/native

Interestingly there is no native ads documentation for swift in flutter. It's only for Objective-c. What is the swift equivalent of these?

Appdelegate:

#import "FLTGoogleMobileAdsPlugin.h"

@implementation AppDelegate
- (BOOL)application:(UIApplication *)application
    didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
  [GeneratedPluginRegistrant registerWithRegistry:self];

  NativeAdFactoryExample *nativeAdFactory = [[NativeAdFactoryExample alloc] init];
  [FLTGoogleMobileAdsPlugin registerNativeAdFactory:self
                                          factoryId:@"adFactoryExample"
                                    nativeAdFactory:nativeAdFactory];

  return [super application:application didFinishLaunchingWithOptions:launchOptions];
}
@end

NativeAdFactoryExample:

/**
 * The example NativeAdView.xib can be found at
 * //github.com/googleads/googleads-mobile-flutter/blob/master/packages/google_mobile_ads/example/ios/Runner/NativeAdView.xib
 */
@interface NativeAdFactoryExample : NSObject <FLTNativeAdFactory>
@end

@implementation NativeAdFactoryExample
- (GADNativeAdView *)createNativeAd:(GADNativeAd *)nativeAd
                             customOptions:(NSDictionary *)customOptions {
  // Create and place ad in view hierarchy.
  GADNativeAdView *adView =
      [[NSBundle mainBundle] loadNibNamed:@"NativeAdView" owner:nil options:nil].firstObject;

  // Associate the native ad view with the native ad object. This is
  // required to make the ad clickable.
  adView.nativeAd = nativeAd;

  // Populate the native ad view with the native ad assets.
  // The headline is guaranteed to be present in every native ad.
  ((UILabel *)adView.headlineView).text = nativeAd.headline;

  // These assets are not guaranteed to be present. Check that they are before
  // showing or hiding them.
  ((UILabel *)adView.bodyView).text = nativeAd.body;
  adView.bodyView.hidden = nativeAd.body ? NO : YES;

  [((UIButton *)adView.callToActionView) setTitle:nativeAd.callToAction
                                         forState:UIControlStateNormal];
  adView.callToActionView.hidden = nativeAd.callToAction ? NO : YES;

  ((UIImageView *)adView.iconView).image = nativeAd.icon.image;
  adView.iconView.hidden = nativeAd.icon ? NO : YES;

  ((UILabel *)adView.storeView).text = nativeAd.store;
  adView.storeView.hidden = nativeAd.store ? NO : YES;

  ((UILabel *)adView.priceView).text = nativeAd.price;
  adView.priceView.hidden = nativeAd.price ? NO : YES;

  ((UILabel *)adView.advertiserView).text = nativeAd.advertiser;
  adView.advertiserView.hidden = nativeAd.advertiser ? NO : YES;

  // In order for the SDK to process touch events properly, user interaction
  // should be disabled.
  adView.callToActionView.userInteractionEnabled = NO;

  return adView;
}
@end

Besides,

How should the ListTileNativeAdView.xib file be?


Solution

  • I found the solution.

    https://codelabs.developers.google.com/codelabs/admob-inline-ads-in-flutter#7

    You can look this section: Implement NativeAdFactory for iOS (Swift)

    ListTileNativeAdFactory.swift:

    // TODO: Import google_mobile_ads
    import google_mobile_ads
    
    // TODO: Implement ListTileNativeAdFactory
    class ListTileNativeAdFactory : FLTNativeAdFactory {
    
        func createNativeAd(_ nativeAd: GADNativeAd,
                            customOptions: [AnyHashable : Any]? = nil) -> GADNativeAdView? {
            let nibView = Bundle.main.loadNibNamed("ListTileNativeAdView", owner: nil, options: nil)!.first
            let nativeAdView = nibView as! GADNativeAdView
    
            (nativeAdView.headlineView as! UILabel).text = nativeAd.headline
    
            (nativeAdView.bodyView as! UILabel).text = nativeAd.body
            nativeAdView.bodyView!.isHidden = nativeAd.body == nil
    
            (nativeAdView.iconView as! UIImageView).image = nativeAd.icon?.image
            nativeAdView.iconView!.isHidden = nativeAd.icon == nil
    
            nativeAdView.callToActionView?.isUserInteractionEnabled = false
    
            nativeAdView.nativeAd = nativeAd
    
            return nativeAdView
        }
    }
    

    AppDelegate.swift:

    import UIKit
    import Flutter
    
    // TODO: Import google_mobile_ads
    import google_mobile_ads
    
    @UIApplicationMain
    @objc class AppDelegate: FlutterAppDelegate {
      override func application(
        _ application: UIApplication,
        didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
      ) -> Bool {
        GeneratedPluginRegistrant.register(with: self)
    
        // TODO: Register ListTileNativeAdFactory
        let listTileFactory = ListTileNativeAdFactory()
        FLTGoogleMobileAdsPlugin.registerNativeAdFactory(
            self, factoryId: "listTile", nativeAdFactory: listTileFactory)
    
        return super.application(application, didFinishLaunchingWithOptions: launchOptions)
      }
    }

    Besides,

    You can use xib file at official github

    https://github.com/googleads/googleads-mobile-flutter/blob/main/packages/google_mobile_ads/example/ios/Runner/NativeAdView.xib
