我正在尝试使用 Facebook SDK (FBAudienceNetwork.framework) 添加原生广告。
我在 Facebook SDK 本身中找到了一个不错的教程。但我的问题是，在 Tableview 中插入广告 时，索引路径会增加。在 didSelectRowAtIndexpath:tableview 中选择单元格时，我得到 增加的 indexpath（错误的）。
我应该怎么做才能获得单元格的确切索引路径？
输出：索引路径 = 0,2
输出：Indexpath = 0,3
感谢任何相关的帮助和建议。干杯！

集成FBNativeads的正确方法是使用FBNativeAdTableViewCellProvider.h类和[self.adsCellProvider adjustCount:self.objects.count forStride:adRowStep];
实施
1) .h 中的声明
@interface TableviewViewController : UITableViewController<FBNativeAdsManagerDelegate>{
int adRowStep;
}
@property (strong, nonatomic) FBNativeAd *nativeAd;
@property (strong, nonatomic) FBNativeAdsManager*adsManager;
@property (retain, nonatomic) FBNativeAdTableViewCellProvider*adsCellProvider;
2) forNumAdsRequested
下的ViewDidLoad（你可以自定义你想要多少广告）-(void)viewDidLoad{
self.adsManager = [[FBNativeAdsManager alloc]initWithPlacementID:@"PLACEMENT_ID" forNumAdsRequested:3];
self.adsManager.delegate = self;
[self.adsManager loadAds];
}
3) 从 FBNativeAdManager 加载的原生广告
-(void)nativeAdsLoaded{
self.adsCellProvider = [[FBNativeAdTableViewCellProvider alloc]initWithManager:self.adsManager forType:FBNativeAdViewTypeGenericHeight120];
self.adsCellProvider.delegate = self;
if (self.tableView != nil) {
[self.tableView reloadData];
}
}
- (void)nativeAd:(FBNativeAd *)nativeAd didFailWithError:(NSError *)error
{
NSLog(@"Native ad failed to load with error: %@", error);
}
- (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.");
}
4) UITableview 部分 + 行设置
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
if (self.adsCellProvider != nil) {
return [self.adsCellProvider adjustCount:self.objects.count forStride:adRowStep];
}
else{
return self.objects.count;
}
return 0;
}
5) 按顺序返回不同的单元格
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
CustomTableViewCell*cell;
if (self.adsCellProvider != nil && [self.adsCellProvider isAdCellAtIndexPath:indexPath forStride:adRowStep]) {
cell = [self.tableView dequeueReusableCellWithIdentifier:@"facebook_cell" forIndexPath:indexPath];
FBNativeAd*nativeAdx = self.adsManager.nextNativeAd;
if (nativeAdx) {
[nativeAdx unregisterView];
}
NSURL*image_url = nativeAdx.coverImage.url;
NSURL*image_icon_url = nativeAdx.icon.url;
dispatch_async(dispatch_get_global_queue(0,0), ^{
NSData * data = [[NSData alloc] initWithContentsOfURL: image_url];
NSData* data2 = [[NSData alloc] initWithContentsOfURL:image_icon_url];
if ( data == nil && data2 == nil)
return;
dispatch_async(dispatch_get_main_queue(), ^{
// WARNING: is the cell still using the same data by this point??
cell.adCoverMediaView.image = [UIImage imageWithData:data];
cell.adIconImageView.image = [UIImage imageWithData:data2];
});
});
// Render native ads onto UIView
cell.adTitleLabel.text = nativeAdx.title;
cell.adBodyLabel.text = nativeAdx.body;
cell.adSocialContextLabel.text = nativeAdx.socialContext;
cell.sponsoredLabel.text = @"Sponsored";
[cell.adCallToActionButton setTitle:nativeAdx.callToAction
forState:UIControlStateNormal];
cell.adChoicesView.nativeAd = nativeAdx;
cell.adChoicesView.corner = UIRectCornerTopRight;
[nativeAdx registerViewForInteraction:cell withViewController:self];
return cell;
}
else{
long dif = indexPath.row - (indexPath.row / adRowStep);
NSDictionary*object = [self.objects objectAtIndex:dif];
//Do whatever you want with your object + create his own cell
// This is not a Facebook Ad Cell
}
}
6) DidSelectRowAtIndexPath --> 用这个架构回答你的问题
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
if (self.adsCellProvider != nil && [self.adsCellProvider isAdCellAtIndexPath:indexPath forStride:adRowStep]) {
}
else{
long dif = indexPath.row - (indexPath.row / adRowStep);
PFObject*sender_obx = [self.objects objectAtIndex:dif];
PostDetailsViewController*rootViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"post_detail_VC"];
rootViewController.post_obx = sender_obx;
rootViewController.post_id = sender_obx.objectId;
[self.navigationController pushViewController:rootViewController animated:YES];
}
}
我就是这样做的。希望对你有帮助
【讨论】：
其实我会把UITableViewCell这个类子类化，并给它添加一个model属性。在TableView的
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
SubCellClass *cell = [tableView dequeueReusableCellWithIdentifier:cellName forIndexPath:indexPath];
cell.model = [self.data objectAtIndex:indexPath.row];
...
}
方法，我来设置模型属性。
当我选择单元格时，我可以调用 cell.model 并直接获取数据。
