    <p>I have <code>DTAttributedTextContentView</code> in UITableViewCell and try to load it with html (with image), but can't find a proper way to do this. I have look into <code>DemoTextViewController.m</code> in Demo which have image load with </p> <pre><code>- (void)lazyImageView:(DTLazyImageView *)lazyImageView didChangeImageSize:(CGSize)size { NSURL *url = lazyImageView.url; CGSize imageSize = size; NSPredicate *pred = [NSPredicate predicateWithFormat:@"contentURL == %@", url]; // update all attachments that matchin this URL (possibly multiple images with same size) for (DTTextAttachment *oneAttachment in [_textView.attributedTextContentView.layoutFrame textAttachmentsWithPredicate:pred]) { oneAttachment.originalSize = imageSize; if (!CGSizeEqualToSize(imageSize, oneAttachment.displaySize)) { oneAttachment.displaySize = imageSize; } } // redo layout // here we're layouting the entire string, might be more efficient to only relayout the paragraphs that contain these attachments [_textView.attributedTextContentView relayoutText]; } </code></pre> <p>But I don't know how this will apply to UITableViewCell I tried</p> <pre><code>- (void)lazyImageView:(DTLazyImageView *)lazyImageView didChangeImageSize:(CGSize)size { NSURL *url = lazyImageView.url; CGSize imageSize = size; NSPredicate *pred = [NSPredicate predicateWithFormat:@"contentURL == %@", url]; for (UITableViewCell *cell in self.tableView.visibleCells) { if ([cell isKindOfClass:[CommentCell class]]) { CommentCell *cc = (CommentCell *)cell; for (DTTextAttachment *oneAttachment in [cc.attributedTextContentView.layoutFrame textAttachmentsWithPredicate:pred]) { oneAttachment.originalSize = imageSize; if (!CGSizeEqualToSize(imageSize, oneAttachment.displaySize)) { oneAttachment.displaySize = CGSizeMake(300, 100); } } [cc.attributedTextContentView relayoutText]; } } } </code></pre> <p>But the cell height not show correctly and the image isn't resize to fit <code>DTAttributedTextContentView</code> size. I can't find any document of how to implement this.</p> <p>If you have a better choice or solution, please tell me.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
