Facebook Audience Network：將FBNativeAd設(shè)置為FBMediaView堆疊UI

編程之家收集整理的這篇文章主要介紹了ios–FBAudienceNetwork：將FBNativeAd設(shè)置為FBMediaView堆疊UI，編程之家小編覺得挺不錯的，現(xiàn)在分享給大家，也給大家做個參考。

以下代碼行使我的UI堆棧

1. adMediaView.nativeAd = nativeAd

2. // adMediaView - FBMediaView

3. // nativeAd - FBNativeAd

我已經(jīng)嘗試將其在后臺線程中異步執(zhí)行,但沒有幫助.有辦法解決嗎？

1. dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_DEFAULT,0),{

2.    adMediaView.nativeAd = nativeAd

3. });

我已經(jīng)通過pod安裝了FBAudienceNetwork,并且更新了它.最新版本是4.7.0

1. pod 'FBAudienceNetwork'

解決方法

NativeAdView使用FBMediaView創(chuàng)建廣告.

現(xiàn)在,在您的View Controller頭文件中聲明了FBNativeAdDelegate協(xié)議,并聲明并將實(shí)例變量連接到您的UI.XIB：

1. @import FBAudienceNetwork; // import Audience Network module

2. @interface MyViewController : UIViewController <FBNativeAdDelegate>

3.  // Other code might go here...

4.  @property (weak,nonatomic) IBOutlet UIImageView *adIconImageView;

5.  @property (weak,nonatomic) IBOutlet UILabel *adTitleLabel;

6.  @property (weak,nonatomic) IBOutlet UILabel *adBodyLabel;

7.  @property (weak,nonatomic) IBOutlet UIButton *adCallToActionButton;

8.  @property (weak,nonatomic) IBOutlet UILabel *adSocialContextLabel;

9.  @property (weak,nonatomic) IBOutlet UILabel *sponsoredLabel;

10.  @property (weak,nonatomic) FBMediaView *adCoverMediaView;

11.  @property (weak,nonatomic) IBOutlet UIView *adView;

12. @end

然后,在View Controller的實(shí)現(xiàn)文件中添加一個初始化FBNativeAd并請求加載廣告的方法：

1. FBNativeAd *nativeAd;

2. FBAdchoicesView *adChoicesView;

3. - (void)showNativeAd

4. {

5.  nativeAd = [[FBNativeAd alloc] initWithPlacementID:@"YOUR_PLACEMENT_ID"];

6.  nativeAd.delegate = self;

7.  [nativeAd loadAd];

8. }

現(xiàn)在,您已經(jīng)添加了加載廣告的代碼,添加以下功能來處理加載故障,并在加載后構(gòu)建廣告：

1. - (void)nativeAdDidLoad:(FBNativeAd *)nativeAd

2. {

3.  [self.adTitleLabel setText:nativeAd.title];

4.  [self.adBodyLabel setText:nativeAd.body];

5.  [self.SocialContextLabel setText:nativeAd.socialContext];

6.  [self.sponsoredLabel setText:@”Sponsored”];

7.  [self.adCallToActionButton setTitle:nativeAd.callToAction];

8.  [nativeAd.icon loadImageAsyncWithBlock:^(UIImage *image) {

9.    [self.adIconImageView setImage:image];      

10.  }];

11.  // Allocate a FBMediaView to contain the cover image or native video asset

12.  adCoverMediaView = [[FBMediaView alloc] initWithFrame:coverFrame]];

13.  [adCoverMediaView setNativeAd:nativeAd];

14.  // Add adChoicesView

15.  adChoicesView = [[FBAdChoicesView alloc] initWithNativeAd:nativeAd];

16.  [adView addSubview:adChoicesView];

17.  [adChoicesView updateFrameFromSuperview];

18.  // Register the native ad view and its view controller with the native ad instance

19.  [nativeAd registerViewForInteraction:adView withViewController:self];

20. }

21. - (void)nativeAd:(FBNativeAd *)nativeAd didFailWithError:(NSError *)error

22. {

23.  NSLog(@"Ad failed to load with error: %@",error);

24. }

要顯示原生廣告封面圖片,建議您使用能夠同時顯示圖片和影片資源的Facebook Audience Network MediaView.
