【中文标题】Facebook 原生广告 FBNativeAdsManagerDelegate 实现方法没有调用

【英文标题】：Facebook Native Ads FBNativeAdsManagerDelegate implementation methods did not called

【问题描述】：

Facebook Native Ads 中的FBNativeAdsManagerDelegate 在 UIViewController 类中正常工作，但在自定义 NSObject 类中使用时它不起作用，即它的委托方法 nativeAdsLoaded 和 nativeAdsFailedToLoadWithError 没有被调用。

CustomFBAd.h 文件

@import FBAudienceNetwork;

#import <Foundation/Foundation.h>

@protocol OnFBNativeAdLoadedDelegate<NSObject>

- (void)onFBNativeAdLoaded:(UIView *)adView;

@end

@interface CustomFBAd : NSObject

@property (nonatomic,weak) id <OnFBNativeAdLoadedDelegate>delegate;

-(void)requestNativeAd:(NSString *)FaceBookPlacementID;
@end

CustomFBAd.m 文件

#import "CustomFBAd.h"

@interface CustomFBAd ()<FBNativeAdsManagerDelegate,FBNativeAdDelegate>

@property (nonatomic, strong) FBNativeAdsManager *manager;
@property (nonatomic, weak) FBNativeAdScrollView *scrollView;

@end
@implementation CustomFBAd

-(void)requestNativeAd:(NSString *)FaceBookPlacementID
    if(FaceBookPlacementID.length != 0)
        FBNativeAdsManager *manager = [[FBNativeAdsManager alloc] initWithPlacementID:FaceBookPlacementID forNumAdsRequested:5];
        manager.delegate = self;
        [FBAdSettings addTestDevice:@"cf1bb93becbe6e31f26fdf7d80d19b4ae225afaa"];
        [manager loadAds];
        self.manager = manager;
    


#pragma mark - FBNativeAdDelegate implementation

- (void)nativeAdDidClick:(FBNativeAd *)nativeAd

    //    NSLog(@"Native ad was clicked.");


- (void)nativeAdDidFinishHandlingClick:(FBNativeAd *)nativeAd

    //    NSLog(@"Native ad did finish click handling.");


- (void)nativeAdWillLogImpression:(FBNativeAd *)nativeAd

    //    NSLog(@"Native ad impression is being captured.");


#pragma mark FBNativeAdsManagerDelegate

-(void)nativeAdDidLoad:(FBNativeAd *)nativeAd




- (void)nativeAdsLoaded

    NSLog(@"Native ads loaded, constructing native UI...");

    if (self.scrollView) 
        [self.scrollView removeFromSuperview];
        self.scrollView = nil;
    

    FBNativeAdScrollView *scrollView = [[FBNativeAdScrollView alloc] initWithNativeAdsManager:self.manager withType:FBNativeAdViewTypeGenericHeight120];
    scrollView.xInset = 0;
    scrollView.delegate = self;
    self.scrollView = scrollView;

    [self.delegate onFBNativeAdLoaded:self.scrollView];


- (void)nativeAdsFailedToLoadWithError:(NSError *)error

    NSLog(@"Native ads failed to load with error: %@", error);


@end

如上述代码中所述，我确实在requestNativeAd 方法中将 FBNativeAdsManager 的委托设置为

manager.delegate = self;

也用作FBNativeAdsManagerDelegate,FBNativeAdDelegate

@interface CustomFBAd ()<FBNativeAdsManagerDelegate,FBNativeAdDelegate>

并将此代码称为

    CustomFBAd *objFBAd = [[CustomFBAd alloc]init];
    objFBAd.delegate = self;
    [objFBAd requestNativeAd:@"my_FB_placement_Id"];

任何线索（注意：如果我在UIViewController 中使用相同的代码）？谢谢

两天后还有 Facebook 的人可以回答吗？

如果您的委托方法在 uiviewcontroller 中被调用，则代码存在问题。我想你必须在你的控制器中有一个强大的 CustomFBAd 参考。因为没有其他参考资料占用您的 CustomFBAd。希望它有所帮助:)

【参考方案1】：

在强烈引用CustomFBAd 之后它终于起作用了，它就像一个魅力（感谢@MuhammadZohaibEhsan）。所以初始化CustomFBAd as

@property(nonatomic, strong) CustomFBAd * objFBAd;

然后改变

    CustomFBAd *objFBAd = [[CustomFBAd alloc]init];
    objFBAd.delegate = self;
    [objFBAd requestNativeAd:@"my_FB_placement_Id"];

到

    self.objFBAd = [[CustomFBAd alloc]init];
    self.objFBAd.delegate = self;
    [self.objFBAd requestNativeAd:@"my_FB_placement_Id"];

我可以发布这个作为答案吗:)

终于救了我。谢谢你:)
