Ich verwende Anzeigen in einem uitableview, wobei jeder vierte Artikel in der Liste eine Anzeige ist.

Question

Ich benutze Anzeigen innerhalb einer UITableView, wobei jeder vierte Artikel in der Liste eine Anzeige ist. Es funktioniert, aber die Anzeige nimmt die Position eines Objekts wie 1-2-3-ad-5-6-7-ad nicht 1-2-3-ad-4-5-6-ad

Meine UITableView Methoden

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { 
    return 2; 
} 

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { 
    if (section==0) 
    { 
      return 0; 
    } 
    else{ 
     return [self.articlesArray count]; 
    } 
} 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 

    NSInteger row = [indexPath row]; 
    if (3 == (row % 4)) { // or 0 == if you want the first cell to be an ad! 
     static NSString *MyIdentifier = @"AdCell"; 
     AdViewCell *cell = (AdViewCell *)[tableView dequeueReusableCellWithIdentifier:MyIdentifier]; 
     if ((cell == nil) || (![cell isKindOfClass: AdViewCell.class] { 
      NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"AdCell" owner:self options:nil]; 
      cell = [nib objectAtIndex:0]; 
      cell = [[AdViewCell alloc] initWithStyle:UITableViewCellStyleDefault 
           reuseIdentifier:MyIdentifier] ; 
     } 
     GADBannerView *bannerView = [[GADBannerView alloc] initWithAdSize:kGADAdSizeMediumRectangle]; 

     bannerView =[[GADBannerView alloc] initWithFrame:CGRectMake(width,heigth,300,250)]; 

     bannerView.adUnitID =@""; 
     bannerView.rootViewController =self; 
     GADRequest *request = [GADRequest request]; 
     [bannerView loadRequest:request]; 

     [cell.contentView addSubview:bannerView]; 

     return cell; 
    } 
    else { 
     static NSString *simpleTableIdentifier = @"ArticleCell"; 
     ArticleViewCell *cell = (ArticleViewCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier ]; 
     cell.selectionStyle = UITableViewCellSelectionStyleNone; 
     if ((cell == nil) || (![cell isKindOfClass: ArticleViewCell.class])) 
     { 
      NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"ArticleCell" owner:self options:nil]; 
      cell = [nib objectAtIndex:1]; 
      cell = [[ArticleViewCell alloc] initWithStyle:UITableViewCellStyleDefault 
           reuseIdentifier:simpleTableIdentifier] ; 
     } 

     NSInteger offset = indexPath.row/4; 
     NSInteger roww = indexPath.row - offset; 
     NSDictionary * tempDictionary = [self.articlesArray objectAtIndex:roww]; 

     NSString *imageUrl = [[self.articlesArray objectAtIndex:indexPath.row]objectForKey:@"featured_image_thumbnail_tab_url"]; 
     imageUrl = [imageUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; 
     [cell.thumbnailImageView sd_setImageWithURL:[NSURL URLWithString:imageUrl ] placeholderImage:nil options:SDWebImageRetryFailed completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) { 
     if (image) { 
      // Set your image over here 
     }else{ 
      //something went wrong 
      NSLog(@"Error occured : %@", [error description]); 
     } 
    }]; 

    NSString * title=[tempDictionary valueForKeyPath:@"title.rendered"]; 

    cell.titleLabel.text = title; 

    NSString * excerpt=[tempDictionary valueForKeyPath:@"excerpt.rendered"]; 
    NSString *excerpt_rend =[self convertHTML:excerpt]; 
    cell.excerptLabel.text = excerpt_rend; 

    return cell; 
    } 
} 

#pragma mark - Navigation 

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender { 
    if ([[segue identifier] isEqualToString:@"showarticle"]){ 
    NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow]; 
    DGArticleViewController *articleViewController = (DGArticleViewController *)segue.destinationViewController; 
    articleViewController.articlesDetails = [self.articlesArray objectAtIndex:rowww]; //rowww = roww 
    NSLog(@"data article %@",articleViewController.articlesDetails); 
} 
} 

Answer 1

führen eine der Anzahl der angezeigten Anzeigen-Offset:

NSInteger offset = indexPath.row/4 
NSIngteger adjustedRow = indexPath.row - offset 
// use row from adjustedRow, instead of indexPath.row 
NSDictionary * tempDictionary = [self.articlesArray objectAtIndex:adjustedRow]; 
... 
NSString *imageUrl = [[self.articlesArray objectAtIndex:adjustedRow]objectForKey:@"featured_image_thumbnail_tab_url"]; 

Auch numberOfRowsInSection: Bedürfnisse angepasst werden, Otherwize Sie fehlende Elemente:

return [self.articlesArray count] + [self.articlesArray count]/4; 

Und in prepareForSegue:

NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow]; 
NSInteger *adjusted = indexPath.row - indexPath.row/4 
... 
articleViewController.articlesDetails = [self.articlesArray objectAtIndex:adjusted]; 
...

Test:

for (int testIndexPathRow = 0; testIndexPathRow < 100; ++testIndexPathRow) { 
    if (3 == testIndexPathRow % 4) { 
     NSLog(@"Ad"); 
    } else { 
     NSInteger offset = testIndexPathRow/4; 
     NSInteger row = testIndexPathRow - offset; 
     NSLog(@"data at index: %d", row); 
    } 
}

Answer 2

Sie müssen die indexpath.row anpassen, um die übersprungenen Zellen widerzuspiegeln. Ersetzen Sie in Ihrem else-Teil indexPath.row mit recordedRow-Nummer.

else 
{ 

static NSString *simpleTableIdentifier = @"ArticleCell"; 
ArticleViewCell *cell = (ArticleViewCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier ]; 
cell.selectionStyle = UITableViewCellSelectionStyleNone; 
if ((cell == nil) || (![cell isKindOfClass: ArticleViewCell.class])) 
{ 
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"ArticleCell" owner:self options:nil]; 
cell = [nib objectAtIndex:1]; 
cell = [[ArticleViewCell alloc] initWithStyle:UITableViewCellStyleDefault 
           reuseIdentifier:simpleTableIdentifier] ; 
} 

NSInteger adjustedRow = indexPath.row - indexPath.row/4; 
NSDictionary * tempDictionary = [self.articlesArray objectAtIndex:adjustedRow]; 

NSString *imageUrl = [[self.articlesArray objectAtIndex:adjustedRow]objectForKey:@"featured_image_thumbnail_tab_url"]; 
imageUrl = [imageUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]; 
[cell.thumbnailImageView sd_setImageWithURL:[NSURL URLWithString:imageUrl ] placeholderImage:nil options:SDWebImageRetryFailed completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType, NSURL *imageURL) { 
if (image){ 
    // Set your image over here 
}else{ 
    //something went wrong 
    NSLog(@"Error occured : %@", [error description]); 
} 
}]; 

NSString * title=[tempDictionary valueForKeyPath:@"title.rendered"]; 

cell.titleLabel.text = title; 


NSString * excerpt=[tempDictionary valueForKeyPath:@"excerpt.rendered"]; 
NSString *excerpt_rend =[self convertHTML:excerpt]; 
cell.excerptLabel.text = excerpt_rend; 

return cell; 
} 

Answer 3

Für Sie Beispiel-Array mit 8 Reihen haben und Sie möchten auch 2 Anzeigen, bedeutet insgesamt 10 Reihen. Aber Sie übergeben nur Array-Anzahl, die ein Problem verursacht. Um diese bitte folgende Code zu lösen

(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{ 
    if (section==0) 
    { 
     return 0; 
    } 
    else 
    { 

     return [self.articlesArray count] + ([self.articlesArray count]/4); 
    } 
} 

Fetch Daten aus dem Array, wie unten angegeben, wird es auf jeden Fall hilft Ihnen

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
     //Your current code 
     int index = indexPath.row/4 
     NSDictionary * tempDictionary = [self.articlesArray objectAtIndex:indexPath.row-index]; 

     //Your current code 
}
