Hi in my app there is an image thumbnail for each table cell
it works but when the image there isn't for that row i'd like to show a default image the image url is retrieved from an html string and put into an array could you help me to write this code?it shows the image when there is but not the default image when there isn't any image

 if ([[item imagesFromContent] count]>0) {

        //if added

        if([[item imagesFromContent] objectAtIndex:0]){
            [cell.thumbnail setImageWithURL:[NSURL URLWithString:[[item imagesFromContent] objectAtIndex:0]]
                           placeholderImage:[UIImage imageNamed:@"thumb.png"]];

        //default image
            [cell.thumbnail setImageWithURL:[NSURL URLWithString:@"img415x280.png"]
                           placeholderImage:[UIImage imageNamed:@"thumb.png"]];

i've tryed also this way

-(NSArray *)imagesFromHTMLString:(NSString *)htmlstr
    NSMutableArray *imagesURLStringArray = [[NSMutableArray alloc] init];

    NSError *error;

    NSRegularExpression *regex = [NSRegularExpression

    [regex enumerateMatchesInString:htmlstr
                              range:NSMakeRange(0, htmlstr.length)
                         usingBlock:^(NSTextCheckingResult *result, NSMatchingFlags flags, BOOL *stop) {

                               //if added

                            if ([htmlstr substringWithRange:result.range]!=nil) {
                                 [imagesURLStringArray addObject:[htmlstr substringWithRange:result.range]];
                                 [imagesURLStringArray addObject:@"img415x280.png"];

    return [NSArray arrayWithArray:imagesURLStringArray];
