    <p>Here's a subclass of <code>UIView</code> that does what you want...</p> <p>You can place it in a <code>UIScrollView</code>. Call <code>-sizeThatFits:</code> to get the correct frame size during your superview's <code>-layoutSubviews</code>. (also for your enclosing scroll view's <em>contentSize</em>.)</p> <p>Note that I included a category on UILabel that returns a reasonable size to <code>-sizeThatFits:</code>, you may want to provide your own implementation.</p> <p><strong>View.h</strong></p> <pre><code>#import &lt;UIKit/UIKit.h&gt; @interface View : UIView @property ( nonatomic, strong, readonly ) UILabel * descriptionLabel ; @property ( nonatomic, strong, readonly ) UILabel * nameLabel ; @property ( nonatomic, strong, readonly ) UIImageView * pdfImageView ; @property ( nonatomic ) CGPDFDocumentRef pdf ; @end </code></pre> <p><strong>View.m</strong></p> <pre><code>#import "View.h" @implementation UILabel (SizeThatFits) -(CGSize)sizeThatFits:(CGSize)fitSize { return [ self.text sizeWithFont:self.font constrainedToSize:fitSize ] ; } @end @interface View () @property ( nonatomic, strong, readonly ) UIImage * pdfImage ; @end @implementation View @synthesize descriptionLabel = _descriptionLabel ; @synthesize nameLabel = _nameLabel ; @synthesize pdfImageView = _pdfImageView ; @synthesize pdfImage = _pdfImage ; -(void)dealloc { CGPDFDocumentRelease( _pdf ) ; } -(CGSize)sizeThatFits:(CGSize)size { CGSize fitSize = (CGSize){ size.width, CGFLOAT_MAX } ; CGSize result = { size.width, 0 } ; result.height = [ self.headerLabel sizeThatFits:fitSize ].height + [ self.label sizeThatFits:fitSize ].height + self.pdfImage.size.height * fitSize.width / self.pdfImage.size.width ; return result ; } -(void)layoutSubviews { CGRect bounds = self.bounds ; CGRect slice ; CGRectDivide( bounds, &amp;slice, &amp;bounds, [ self.headerLabel sizeThatFits:bounds.size ].height, CGRectMinYEdge ) ; self.headerLabel.frame = slice ; CGRectDivide( bounds, &amp;slice, &amp;bounds, [ self.label sizeThatFits:bounds.size ].height, CGRectMinYEdge ) ; self.label.frame = slice ; self.pdfImageView.frame = bounds ; } -(void)setPdf:(CGPDFDocumentRef)pdf { CGPDFDocumentRelease( _pdf ) ; _pdf = CGPDFDocumentRetain( pdf ) ; _pdfImage = nil ; } -(UILabel *)descriptionLabel { if ( !_descriptionLabel ) { UILabel * label = [[ UILabel alloc ] initWithFrame:CGRectZero ] ; label.numberOfLines = 0 ; // // ... configure label here // [ self addSubview:label ] ; _descriptionLabel = label ; } return _descriptionLabel ; } -(UILabel *)nameLabel { if ( !_nameLabel ) { UILabel * label = [[ UILabel alloc ] initWithFrame:CGRectZero ] ; label.numberOfLines = 0 ; // // ... configure label here // [ self addSubview:label ] ; _nameLabel = label ; } return _nameLabel ; } -(UIView *)pdfImageView { if ( !_pdfImageView ) { UIImageView * imageView = [[ UIImageView alloc ] initWithFrame:CGRectZero ] ; [ self addSubview:imageView ] ; _pdfImageView = imageView ; } return _pdfImageView ; } -(UIImage *)pdfImage { if ( !_pdfImage ) { CGPDFPageRef page = CGPDFDocumentGetPage( self.pdf, 1 ) ; // 1 indexed CGRect mediaBox = CGPDFPageGetBoxRect( page, kCGPDFMediaBox ) ; UIGraphicsBeginImageContextWithOptions( mediaBox.size, NO, self.window.screen.scale ) ; CGContextRef c = UIGraphicsGetCurrentContext() ; CGContextScaleCTM( c, 1.0f, -1.0f ) ; CGContextTranslateCTM( c, 0.0, -mediaBox.size.height ) ; CGContextDrawPDFPage( c, page ) ; _pdfImage = UIGraphicsGetImageFromCurrentImageContext() ; self.pdfImageView.image = _pdfImage ; UIGraphicsEndImageContext() ; } return _pdfImage ; } @end </code></pre> <p>If you need a page number footer, you can add another UILabel at the bottom, following the same pattern.</p>

    1. COThanks for the answer! I was trying yesterday and I saw that the image can easily be drawn at the end if i put a [self drawImage] after the statement if (currentRange.location == CFAttributedStringGetLength ((CFAttributedStringRef)currentText)) I'll try your version and I'll let you know!

    2. COwhichever you find easier--I like this because it's just 3 subviews... performance should also be good. If you want multiple pages, just make multiple views.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
