моя проблема в том, что я не могу разобрать тег из XML-файла. Он возвращает нулевое значение, im тестируя его, используя NSLog с% @.Разбор содержимого xml тега
Если кто-то может указать мне решение, я был бы очень благодарен.
Вот код: BOOL обрабатывается = НЕТ; , если (currentText) {
// Remove newlines and whitespace from currentText
NSString *processedText = [currentText stringByRemovingNewLinesAndWhitespace];
// Process
switch (feedType) {
case FeedTypeRSS: {
// Item
if (!processed) {
if ([currentPath isEqualToString:@"/rss/channel/item/title"]) { if (processedText.length > 0) item.title = processedText; processed = YES; }
else if([currentPath isEqualToString:@"/rss/channel/item/url"]) { if (processedText.length > 0) item.image = processedText; processed = YES; }
else if([currentPath isEqualToString:@"/rss/channel/item/category"]) { if (processedText.length > 0) item.category = processedText; processed = YES; }
else if ([currentPath isEqualToString:@"/rss/channel/item/link"]) { if (processedText.length > 0) item.link = processedText; processed = YES; }
else if ([currentPath isEqualToString:@"/rss/channel/item/guid"]) { if (processedText.length > 0) item.identifier = processedText; processed = YES; }
else if ([currentPath isEqualToString:@"/rss/channel/item/description"]) { if (processedText.length > 0) item.summary = processedText; processed = YES; }
else if ([currentPath isEqualToString:@"/rss/channel/item/content:encoded"]) { if (processedText.length > 0) item.content = processedText; processed = YES; }
else if ([currentPath isEqualToString:@"/rss/channel/item/pubDate"]) { if (processedText.length > 0) item.date = [NSDate dateFromInternetDateTimeString:processedText formatHint:DateFormatHintRFC822]; processed = YES; }
else if ([currentPath isEqualToString:@"/rss/channel/item/enclosure"]) { [self createEnclosureFromAttributes:currentElementAttributes andAddToItem:item]; processed = YES; }
else if ([currentPath isEqualToString:@"/rss/channel/item/dc:date"]) { if (processedText.length > 0) item.date = [NSDate dateFromInternetDateTimeString:processedText formatHint:DateFormatHintRFC3339]; processed = YES; }
}
// Info
if (!processed && feedParseType != ParseTypeItemsOnly) {

вызов метода:
// Настройка внешнего вида таблицы элементов. - (UITableViewCell *) Tableview: (UITableView *) Tableview cellForRowAtIndexPath: (NSIndexPath *) indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
// Configure the cell.
MWFeedItem *item = [itemsToDisplay objectAtIndex:indexPath.row];
if (item) {
NSLog(@"content = %@",item.content);//<-------------------------------------------Returns a NULL
// Process
NSString *itemTitle = item.title ? [item.title stringByConvertingHTMLToPlainText] : @"[No Title]";
NSString *itemSummary = item.summary ? [item.summary stringByConvertingHTMLToPlainText] : @"[No Summary]";
// Set
cell.textLabel.font = [UIFont boldSystemFontOfSize:15];
cell.textLabel.text = itemTitle;
NSMutableString *subtitle = [NSMutableString string];
if (item.date) [subtitle appendFormat:@"%@: ", [formatter stringFromDate:item.date]];
[subtitle appendString:itemSummary];
cell.detailTextLabel.text = subtitle;
}
return cell;
}
